Best Lightweight Weed Eater

If you are in a hurry, here are the best small lightweight weed eaters available, then see the two products below. Each of them has been tested and compared to offer a high-quality product under 10 lbs in total weight.

Worx GT 3.0 PowerShare 20V

Ultra-lightweight string trimmer lawn edger combo. Excellent run-time of 40 minutes. 2 x 2.0 Ah batteries included.

BlackDecker 20V MAX

Weighing just 4.5 lbs a great 2-in-1 lightweight small trimmer and lawn edger. 30-minute run-time.

Choosing the Best Small Lightweight Weed Eater

Before you buy a weed eater, there are a few essential things to know. These will help you choose a lightweight and small weed eater that has all the functionality you need.

Overall Weight Balance

The weight and balance of a weed eater are particularly important aspects to consider for this review. However, it needs to be appreciated that in the process of manufacturing to reduce weight, often means reducing materials or components.

This can result in more fragile lightweight plastic castings or smaller battery capacity. So, there is often a trade-off.

The lightest machines can weigh as little as 5 lbs, but I have limited all products to under 10 lbs in total weight including the battery unit.

A well-balanced trimer can often handle and feel lighter than its actual weight. So, I have considered ‘real feel’ and excluded any machine that was off-balance or awkward and may have put a strain on your wrists.

Electric Corded Weed Eater

Electric corded weed eaters, as the name implies, are powered by a 120V mains electric power cord. This design often has more power than a battery-powered model, plus the advantage of not requiring charge time.

However, the drawback to this design is the need to plug them into a fixed electrical outlet reducing mobility. Oftentimes you will also need to purchase additional extension cords to get the required distance to use the tool across your yard.

If you have a huge area to cover then an electric corded weed eater might not be the ideal choice for you.

Alternatively, an electric model can be an excellent choice if you have a small to the medium-sized yard, in this scenario, it will offer relatively high power at a low cost.

Motor Power (Amps)

Most electric corded weed eaters have a motor power between 1 and 10 amps. While a higher amp measure does indicate a more powerful motor, this is not always necessarily translated into higher torque and RPM.

Given our objective is to identify a lightweight weed eater, it seems fair to presume we are not doing to get heavy-duty performance from it. So, for most lightweight trimming applications around four amps of power will be adequate; for trimming grass, edging, light weeds, and so on.

Moveability

One drawback of electric corded weed eaters is the lack of moveability compared to battery-powered designs. There is always a trade-off. A battery has a limited run time, and a corded weed eater has a limited distance of travel due to being tethered to a power outlet.

Each model will have a different cord length, so be sure to check out your needs and purchase a suitable length of extension cord, to make sure all of your yard is accessible with your new weed eater.

Battery-Powered Weed Eater

Battery-Operated Weed Eaters bring a different set of advantages and disadvantages when compared to a corded product. They are often more expensive to purchase, as lithium-ion battery cells, or expensive to manufacture.

Batteries are heavy items, so when you add a battery to the lightweight battery-operated weed eater, it can add a notable amount of weight to the overall design and potentially cause an imbalance in the feel of the trimmer. But don’t worry…I will detail this under the product reviews section later in this article.

They also have a run-time limited to the storage capacity of the battery (I will talk more about this shortly). But you can always purchase more than one battery cell and simply switch it out and re-charge them on rotation.

However, there is one huge advantage to a battery-weed eater, unrestricted mobility. You can weave around your yard without getting in a tangle. In fact, you can throw your weed eater in your vehicle and take it anywhere you need to use it.

Battery Run Time (Ah)

Ampere-hours (Ah) is a measure of the lithium-Ion battery storage capacity. For example, you may have a battery of 2.0Ah, which means the battery will discharge 2.0 amps over one hour of use.

Think of it like this. If you have a battery that will discharge 2.0 Amp over 2 hours, and you use it on a weed eater that consumes 4.0 Amp per hour. You will get 30 minutes of charge time from a 2.0Ah battery for that particular weed eater.

In general, the higher the Ah the longer the machine will be powered. But…we are looking for lightweight weed eaters, right? So I have only selected products with lower Ah ratings and have converted this into run-time in minutes for easy comparison.

Battery Weight

A 2.0Ah battery cell can add 2lbs to a machine and a 4.0Ah battery 3lbs. If weight is a concern for you then it is often better to keep your battery size small and possibly buy an additional battery cell for longer run times.

Gas Weed Eater

A gas weed eater is traditionally powered by a 2-cycle engine. While there are advantages to this, like very high-power output, many people don’t like using them because they emit unpleasant fumes and a lot of noise.

But I can keep this section short. If our goal is to find a lightweight weed eater for residential use, then we can skip over gas-powered machines and stock with electric technology. It is easier to maintain, quieter, cleaner, and of course lighter.

Straight or Curved Shaft

Weed eaters may have either straight shafts or some shaped like the letter J. This shape can affect not only comfort and balance but even performance and weight distribution.

Controls Features

In addition to the regular features of a weed eater, some models have unique features. These can include anything from interchangeable heads to make cutting in tight corners to various power settings easier. So, let’s take a look at some of the more common features.

String Trimmer Line Cut Path

The cut path (cutting path) refers to the reach of the string trimmer line in both trimming material and ejecting debris. Essentially it is the cutting diameter of the rotating trimmer blade or string.

Most lightweight weed eaters intended for domestic use have a cut path between 10 and 14 inches. This is simply a matter of where you are going to use it. Go for smaller sizes if you have intricate areas, to trim or obstacles to cut around. Larger sizes will obviously clear more areas faster.

Lawn Edger Function

Traditionally, a lawn edger is an entirely separate garden power tool from a weed eater. However, many modern designs combine the two functions. Making them a great choice if you’re looking for versatility and value.

A lawn edger is a tool designed to sculpt the edge of your lawn. It cuts back grass growing over the edge of the lawn edging. If this isn’t a priority for you, you can decide whether you want this feature in a weed eater or not.

Interchangeable Head

Some weed eater models are designed so that you can switch the head out for different tools. These can vary in terms of the material they can handle (brush, grass, bushes, etc.), the amount of power they use, and the type of shaft they complement.

While people with straightforward yard work needs probably don’t need them, they can be beneficial for avid landscapers. But my recommendation is not to worry about this multi-functional type of weed eater, as the lightweight products are just not powerful enough to get value from this type of feature. It is really intended for high-powered brush cutters.

Line Feed Type

Weed eaters use plastic or composite string-like cutting lines. With use, the line will break off when it wears through, or maybe hits concrete paving. When this happens, you will need to feed a new section of line off the line spool and off you go again.

There are three methods of feeding line:

Manual Line Feed: This requires the operator to stop the machine, power it off, and feed new line by hand

Bump Line Feed: The operator can literally bump the head off the weed eater on the ground during operation, and a spring button will release a new length of the line.

Automatic Line Feed: The trimmer will identify when the line has snapped and automatically feed out a new length of the line during operation, allowing uninterrupted operation of the machine.

Speed Control

Some weed eaters have various speed control settings. At their most basic, these range from high efficiency/high power usage to lower efficiency/lower power usage.

Handles

Weedeater handles can vary in grip, comfort, and other features. You may want to compare different grips before buying to decide which is most comfortable for your needs.

Best Lightweight Weed Eater Reviews

The aim of this review is to find the best lightweight weed eater. For the test criteria, every weed eater is required to weigh less than 10 lbs with a battery. Product build quality, cutting performance, and additional features such as Edger function, are key benefits identified within the comparison.

Finally, for battery-operated trimmers, run-time, and battery charge time are also taken into consideration.

Emily Estep is a plant biologist and journalist who has worked for a variety of online news and media outlets, writing about and editing topics including environmental science and houseplants.

Whether you call it a “weed eater,” “weed whacker,” or “string trimmer,” these landscaping tools are ideal for trimming grass and weeds along the edge of a flowerbed, around a tree trunk, underneath a deck, and in other hard-to-reach places.

Jeremy Yamaguchi, the CEO of Lawn Love, says, “A weed whacker can quickly and effectively trim grass, weeds, and other unwanted plant growth in areas difficult to reach with a mower or shears. When choosing one, the most important thing to look for is the power it offers, as well as the size and weight of the tool. Gas weed eaters are the most powerful, but electric models are best for most homeowners.”

He cautions, “To ensure safe use of a weed whacker, always wear the appropriate protective gear, including goggles and gloves, stand with your feet apart for balance, hold the tool’s handle firmly but comfortably with both hands, and never operate the weed whacker without its guard attached.”

Best Overall

Ryobi 40-Volt Lithium-Ion Brushless Electric Cordless String Trimmer

If you want the power of a gas weed eater but the convenience of a battery-powered tool, then this 40-volt offering from Ryobi is the answer. Our top choice of string trimmer is loaded with great features, including a brushless motor for longer life with less required maintenance and an adjustable handle so you can position it comfortably for your height. We also appreciate its two-speed trigger with variable speed control, so you can go faster when you need extra power for tough weeds or brush, and slow the tool down to extend the battery run-time when merely cutting small weeds and grass. Plus, it has an adjustable cutting width, with a minimum of 13 inches and a maximum of 15 inches.

This string trimmer comes with 0.085-inch string, which is good for trimming grass and weeds, but you can also load it with 0.095-inch string if desired for tackling tougher weeds, light brush, or thick grass. Either way, the weed whacker is very easy to reload, thanks to the REEL EASY head, which can be rewound in under 60 seconds. When you want to let out more string, a gentle bump of the tool against the ground advances just the right amount so you can keep working without having to stop and let out line by hand. The tool also comes with a set of serrated plastic blades, which can be fitted into the tool’s head in place of string. Use the blades for cutting tougher brush and weeds. While not nearly as strong as metal blades, these do a good job on softer weeds and grasses, but they aren’t sturdy enough for woody weeds.

This versatile weed eater works with the Ryobi line of Expand-It accessories, sold separately, which can turn your string trimmer into a pole saw, electric hedge trimmer, soil cultivator, snow thrower, blower, and more quickly and easily. The weed whacker comes with one Ryobi lithium-ion 40-volt battery and charger, which are compatible with any other Ryobi tool using a 40-volt battery. Depending on conditions, you can get up to one hour and 10 minutes of run-time from the battery before needing to recharge.

Best Budget

Greenworks 5.5 Amp 15-Inch Corded Electric String Trimmer

Just because a weed whacker comes at a budget price, that doesn’t mean you have to forgo great features, as this corded electric offering from Greenworks proves. Plug the tool into an outdoor-rated extension cord up to 100 feet in length; no smelly gasoline fumes or worrying about a battery running down before you finish. Suited to a small-to-medium yard, this string trimmer’s head easily pivots for use as a trimmer or an edger, doubling its versatility. It has a 15-inch cutting swath and uses 0.065-inch string, which automatically advances as the exposed string wears down. When you need to reload the string, you can use pre-filled spools or rewind bulk string onto the spool that comes with the tool. However, you cannot use heavy-weight string with this weed eater, and if you choose to rewind the spool, rather than replace it, it can be a bit tricky to do correctly.

The handle telescopes from 40 inches to 50 inches, and the grip is also adjustable, so you can set the weed whacker to fit your own height, making it comfortable to use for lengthy gardening sessions. Its 5.5-amp motor runs smoothly and quietly and has enough power to quickly cut through grass and non-woody weeds. At only seven pounds, this is a reasonably lightweight string trimmer, so it won’t wear you down before the job is through.

Best Gas

Echo 25.4 cc Gas 2-Stroke Straight Shaft Trimmer

If you have a large area of brush, overgrown grass, or woody weeds to clear, then you’ll appreciate the extra power of a gas weed eater like this offering from Echo, which runs on a 25.4 cc, professional-grade two-stroke engine. Like other gas-powered weed eaters, you’ll need to fill the gas tank with a 50:1 ratio of fuel to oil mix. Echo’s i-30 starting system makes it much easier to start up this weed eater than most others, and once powered on, this sturdy beast chews steadily through just about anything you ask it to. The handles are padded and ergonomically shaped for comfort and are also designed to greatly reduce the amount of vibration that reaches your hands and arms.

The 0.095-inch heavy-duty string advances with a bump of the tool against the ground. When the string runs out, the Echo Speed-Feed system requires no tools and takes only seconds to reload; no frustrating fuss or bother. With a 17-inch cutting swath, you can work your way across the lawn quickly. Should you need even more powerful cutting action, Echo sells a separate conversion kit that lets you swap out the string head for a metal-bladed head that easily cuts through thick underbrush and overgrown weeds. Be aware that this weed eater is quite loud and does emit gas fumes, as is typical for gas-powered tools.

Best Cordless/Battery

Ryobi ONE 18-Volt Cordless Battery String Trimmer

Go cordless with this lightweight string trimmer that’s designed to take care of small-to-medium yards. The curved shaft makes it easy to maneuver around shrubs, rocks, and tree trunks, and the handle is ergonomically designed for a comfortable grip. Plus, weighing a mere four pounds, this is a weed eater that shouldn’t tire you out. It’s powered by an 18-volt battery that recharges in an hour and runs for anywhere from 8 to 15 minutes per charge, depending on how you use it. And with a simple push of a button, you can switch the head’s orientation: use it horizontally for trimming and vertically for edging.

The cutting swath of this tool is 10 inches, which is on the small side but can be a good thing if you are edging a flowerbed or other area with many obstacles to work around. It can only use 0.065-inch string and automatically feeds out more string as required. It’s not too difficult to reload once the string runs out. The weed whacker comes with an 18-volt battery that can be used in other 18V Ryobi tools, as well as a charger. Note that it is not compatible with Ryobi’s Expand-It attachments, however.

Best Corded Electric

Ryobi 10-Amp Attachment-Capable Corded String Trimmer

As long as you have an outdoor-rated extension cord up to 100 feet, and you don’t need to trim beyond that point, a corded electric weed eater is a great option. You get a lot of power, like you would from a gas-powered tool, but you also get the benefits of a cordless tool, including no smelly fumes, no need to keep gasoline on hand, and an easy start at the push of a button. Plus, there’s no need to worry about your battery running out too soon. This corded weed whacker from Ryobi is loaded with great options beyond the above: It has a 10-amp motor for maximum performance, it cuts an impressive 18-inch path, and it is designed to reduce vibrations through the handle, so it’s easy on your hands, although it is relatively heavy for this type of tool.

The tool comes with 0.080-inch string, but can also use 0.095-inch string if you need something even more heavy-duty. String advances with a bump of the tool to the ground, and when it’s time to replace the reel, it’s very easy to install a new one or simply rewind bulk string around the reel. Best of all, this string trimmer is compatible with Ryobi’s extensive line of Expand-It attachments, meaning you can purchase a wide variety of optional attachments to turn the weed whacker into a brush cutter, hedge trimmer, pole saw, snow thrower, and more. However, its head does not pivot for use as an edger, as do many other weed eaters.

Best Under 200

BLACKDECKER 20V 12 Inch Lithium Ion Cordless 2-in-1 Trimmer/Edger

Here’s a reasonably priced tool that effectively whacks weeds with the head in a horizontal position and then serves as an edger when you rotate the head into a vertical orientation. This battery-powered, 20-volt string trimmer from BLACKDECKER is perfect for small-to-medium-sized lawns and has enough power to chew through typical grass and weeds (although this isn’t the tool for tough brush or heavily overgrown lawns). You can adjust the handle up or down to suit your height. The cutting width of this weed eater is set at 12 inches, which is somewhat narrow but sufficient for small yards.

The weed eater comes with 0.065-inch line, which is suited to light use on grass and small weeds. Note that you cannot refill it with heavier line. The line advances automatically as it wears down with use, so you don’t need to carry the task out manually or bump the tool on the ground. The weed whacker comes with the 20-volt battery and charger, which are compatible with other BLACKDECKER cordless tools. Run-time before needing to recharge the battery varies greatly, depending on yard conditions, but you will typically get anywhere from 15 minutes to 30 minutes on a single charge, which is enough to finish trimming or edging a small lawn.

Best Rated

WORX WG163 GT 20V Power Share Cordless String Trimmer Edger

The WORX Power Share cordless weed eater just keeps racking up high ratings; this weed whacker has more than 20,000 customer ratings and an average of 4.5 stars. But that’s not really surprising, considering that this 20-volt tool comes with two batteries, so you can have one charging and one in use, doubling your working time. The batteries and charger are compatible with any other 20-volt WORX tool. You can easily pivot the head on the weed eater to turn it from trimmer to edger, and it’s easy to angle it for use on a slope or when reaching into awkward spots between plants or around obstacles. When using it as an edger, its rubber wheels help you stay in a steady line.

This weed whacker uses 0.065-inch string, which is easy to advance at the push of a button, thanks to the Command Feed spool system. But most amazing of all, WORX will send you free refill spools of string for the life of the tool; you just pay for shipping. This will come in handy, since the string can run out quickly. It also has a 12-inch cutting diameter, which isn’t the highest but is quite sufficient for average-sized lawns and yards. And at only 5.3 pounds, this is a lightweight string trimmer that’s easy to use even when your gardening sessions stretch out long.

Best Splurge

DeWALT 60-Volt Cordless Attachment-Capable String Trimmer Kit

If you use your string trimmer frequently and want lots of power as well as useful features, then you’ll appreciate the DeWALT weed whacker, which is a cordless model running off a 60-volt battery; that’s a lot of power, although it does add to the overall weight of the product. The high-efficiency brushless motor requires no maintenance to keep on running smoothly and fairly silently. There’s a two-speed, variable control trigger, so you can turn it up high when you need maximum power for chewing through brush or tall grass, or turn it down low to extend the battery run-time. You can even adjust the cutting width between 15 and 17 inches.

The weed whacker comes with 0.080-inch string, but the tool can also use 0.095-inch string if you need something even more heavyweight. To advance more string, just bump the weed eater lightly against the ground. The quick-load spool makes it easy to refill the string once you run out. If you want even more versatility from this weed eater, you’ll like its universal-attachment capability, which means you can purchase a wide variety of attachments from DeWALT or other companies to transform the weed whacker into a brush cutter, hedge trimmer, pole saw, blower, tiller, and more. It comes with a 60-volt DeWALT battery that is compatible with other tools from this company, as well as a charger.

Best with Attachments

BLACKDECKER Corded String Trimmer With Lawn Mower Attachment

With most models of string trimmers, you have to purchase attachments separately. However, this 6.5-amp corded electric weed whacker from BLACKDECKER comes with a lawnmower attachment, making this a highly versatile tool for small backyards. In fact, it’s three tools in one: edger, string trimmer, and lawnmower. It’s especially good for mowing on slopes or hills where a traditional lawnmower can be hard to maneuver. And it can be used with an outdoor-rated extension cord up to 150 feet in length, so you can work your way around most small yards. Since there is no way to add a clipping bag to the tool, you can leave the grass clippings in place on the lawn to decompose into mulch or rake them up once you are finished mowing.

The string trimmer uses 0.065-inch string. There’s an automatic string feed, so you don’t have to stop and reel string out yourself or worry about bumping it against the ground while mowing. As a weed eater, the cutting swath is 12 inches. It pivots easily into edger mode. For use as a mower, the trimmer simply snaps into the mower base. You can adjust the mower’s cutting height from 1.6 inches to 2.4 inches; the mower does not have blades, but simply uses the spinning string to cut the grass, and it does a great job on most lawn types. You can even adjust the height of this tool’s handle between 33 inches and 43 inches to make it comfortable for your height.

Milwaukee M18 FUEL Cordless Quik-Lok String Trimmer

This professional-quality cordless string trimmer has the kind of power and run-time you’d expect from a gas weed eater, thanks to its M18 8.0-Ah lithium-ion battery. This sturdy weed whacker consists of two parts: a Milwaukee M18 FUEL power head with Quik-Lok and a Milwaukee M18 FUEL Quik-Lok string trimmer attachment. You can use any of Milwaukee’s other compatible attachments with the fuel head, making this a very versatile tool that can carry out a wide range of landscaping tasks. It has enough power to clear through thick brush, overgrown grass, and heavy weeds, reaching full throttle in less than a second and maintaining power without bogging down. The tool is designed for good balance, making it easy to carry and comfortable to use, even on lengthy yard tasks.

A variable-speed trigger lets you go faster when you need more power, or slow things down when you want to extend battery run-time as much as possible. The cutting width of the weed whacker adjusts from 14 to 16 inches. The string that comes with the tool is 0.080 inches, but you can also use it with heavier 0.095-inch line. Either way, you can reload the string reel in just a few seconds. When the string gets short during use, just bump the trimmer against the ground to advance more string. Not everyone needs a weed eater with this kind of power and at this price point, but for those who do, it’s hard to beat this offering from Milwaukee.

Type: Cordless electric | Weight: 12.3 pounds | Engine/Battery Power: 18 volts | Shaft Type: Straight | Maximum Cutting Width: 16 inches

If you’re looking for a cordless electric weed eater that not only has plenty of power but is also loaded with great features like an adjustable cutting swath, variable speed control, and compatibility with numerous attachments for other landscaping purposes, then it’s hard to go wrong with the Ryobi 40-Volt Brushless Electric String Trimmer. But if you need the kind of power that only a gas tool can deliver, then the Echo 25.4 cc Gas 2-Stroke Straight-Shaft Trimmer is our recommendation. It has a 17-inch cutting swath and can be converted for use with metal blades instead of string.

What to Look for in a Weed Eater

Type

There are three basic types of weed eaters, based on their power source.

Gas-powered weed whackers like the Echo 25.4 cc Gas 2-Stroke Straight Shaft Trimmer are the most powerful type, making them the best suited for large properties or for chewing through heavy brush. On the downside, they are much louder than electric models and can be heavier and more difficult to start. Plus, they require you to have a supply of gasoline on hand, and in many areas, they are being phased out due to their emissions.

Corded electric string trimmers are not as popular as they once were, but are still a fine choice if you are looking for a low-priced weed eater, you don’t have a very large lawn or garden to maintain, and you have access to an outdoor electrical outlet and an outdoor-rated extension cord of 50 feet or more. The Ryobi 10-Amp Attachment-Capable Corded String Trimmer has an 18-inch cutting swath and great power.

Cordless or battery-powered weed eaters are now the most popular type—the WORX Power Share WG163 is an especially highly rated option—particularly in areas where gas-powered models are restricted. Today’s cordless weed whackers have good power, although not as much as a gas-powered model. Still, they have more than enough oomph to maintain a small to medium-sized lawn. As a rough guideline, you’ll generally get half an hour or so of runtime before you need to recharge the battery. For many people, that’s all that’s needed to get the job done. If you have a big lawn, then it’s convenient to keep two batteries on hand so one can recharge while the other is in use. Other benefits of cordless weed whackers include a lack of smelly emissions, immediate starting at the press of a button, reduced vibrations, and quiet operation.

Cutting Width

A string trimmer’s cutting swath or cutting width is the width of the tool’s cutting capacity, indicating how much you’ll be able to trim in one pass. There are weed whackers with cutting swaths as small as 10 inches, and weed eaters with large 20-inch cutting widths, but most are between 12 and 16 inches. If you have a large lawn, a string trimmer with a wide cutting swath will help you trim more quickly. But if you need a tool that can squeeze between shrubs, rocks, or other obstacles, then you’ll find that a weed wacker with a smaller cutting swath can maneuver a bit more easily.

Some higher-end weed eaters have adjustable cutting swaths that let you go up or down a couple of inches. Our top choice, the Ryobi 40-Volt Brushless Electric String Trimmer, can be adjusted for cutting widths between 13 and 15 inches.

Noise Level and Vibrations

Generally, cordless string trimmers are fairly quiet; you’ll mostly hear the whirl of the string and the sound of grass or weeds giving way. However, gas-powered weed whackers are loud enough to require ear protection during use, and corded electric models may or may not be loud enough to make you want to cover your ears, depending on the brand and model. However, you should wear eye protection when using any type of weed eater, as there is always a danger of stones or debris being tossed up into your face.

Vibration can be an issue with many weed eaters, especially gas-powered models. This can be tiring if you are using the tool for an extended session of trimming or chewing through brush. Some brands now build anti-vibration technology into their string trimmers, usually in the form of a handle that helps reduce some of the vibration. You can cut down even further on unpleasant hand numbness or fatigue by wearing a good pair of thick work gloves while you use your weed eater.

Weight

Since you’ll be holding your weed eater the entire time you are working, its weight can become an issue. You don’t want to be tired out before you finish your edging or trimming. As a general rule, electric weed eaters are quite a bit lighter than gas-powered models. The Ryobi ONE 18V Cordless Electric String Trimmer weighs a mere four pounds.

Most electric weed eaters weigh 12 pounds or less, although battery-powered models are usually heavier than those with a cord. Gas weed whackers generally weigh between 12 and 18 pounds.

Safety Features

Any weed eater should have a protective guard over the string to help keep rocks and other debris from flying toward you. However, you should always wear closed shoes, long pants, and eye protection when using these tools. Most weed whackers have the power switch placed so you can easily shut the tool off immediately should there be an emergency.

Straight or Curved Shaft

There are two basic styles of weed eater shafts: straight and curved. Curved shafts are generally easier to maneuver around rocks and other obstacles and are less tiring to the user’s back during long work sessions. However, straight shafts give you more reach and can be extended underneath shrubs or fences. Weed eaters with straight shafts often have a little more power, and battery run-time tends to be a little longer on these tools as well, but the choice between the two mostly comes down to personal preference.

String Control

Weed whackers work by spinning a thin plastic string-like cord very rapidly, which creates enough force to slice through grass, weeds, and brush. Most weed eaters have a roll of string within the base of the tool, so you can reel out more as the cord wears down, which can happen fairly quickly when working on thick brush or grass. There are three basic methods for reeling out more cord:

• Automatic feed senses when the cord is getting short and reels out more without you needing to do anything. The Greenworks 5.5 Amp 15-Inch Corded Electric String Trimmer is an auto-feed weed whacker.
• Push-button feed requires you to push a button on the weed eater’s handle to reel out more string.
• Bump-feed weed eaters reel out more cord when the trimmer is bumped against the ground.

Once the reel of string is empty, you’ll need to refill it. This is a fairly simple process for most weed eaters, but be sure to read the instructions before attempting it for the first time.

Note that there are also different thicknesses of string-trimmer lines or strings: as a general rule, 0.065-inch to 0.085-inch string is for light-to-moderate trimming of grass and weeds. For heavier weeds, brush, or tough grass, string that’s between 0.085-inches and 0.110-inches is required. Many string trimmers can use different sizes of line so you can switch them out if necessary.

Standout Features

Speed Control

Most string trimmers have just one set speed. Some higher-end models, including the Milwaukee M18 FUEL Cordless String Trimmer, however, let you adjust the speed with either a two-speed setting or variable control. This allows you to speed up the tool for more power while tackling thicker growth or tougher brush, or slow the speed down to extend battery run-time when working on small weeds or grass.

Attachments

Some string trimmers have heads that can be adjusted from a horizontal position to a vertical orientation, which allows them to be used as an edger as well as a trimmer. Others, including the DeWALT 60-Volt Cordless Attachment-Capable String Trimmer Kit, allow you to attach a variety of separately purchased heads for other landscaping tasks such as cultivating soil, shearing hedges, mowing grass, or blowing leaves.

The vast majority of weed eaters are stringed tools, using a thin plastic cord that spins very rapidly to cut through grass and weeds. There are more powerful, but similar tools often called “brush cutters,” that use metal blades instead of plastic cord to chop through thick brush, tough weeds, and highly overgrown grass. Some weed eaters can be converted for use with blades as well as with plastic cord. Typically, only a gas weed eater has the power to convert to metal blades for cutting thick brush. The electric corded or cordless models that can cut with blades, as well as cord, typically can only handle plastic blades. These can cut light brush but can’t handle thick, woody stems as a metal-bladed brush cutter can. Neither a string nor blade weed eater is necessarily better; the best choice depends on your specific needs and the condition of your property.

Both gas and electric weed eaters have their pros and cons. Gas-powered weed eaters are stronger and aren’t tethered to an electrical outlet. However, gas weed eaters require filling with gas and oil and create smelly fumes. They are generally much louder than electric models and vibrate more during use. They are also heavier and more costly than electric models. However, for maintaining a large property or tackling thick brush or very overgrown weeds, a gas weed eater can be the better choice. For most yard cleanup, however, an electric weed eater, whether corded or cordless, is sufficient to handle grass, weeds, and light brush that isn’t too woody. Electric weed eaters don’t create smelly fumes and don’t require you to keep gasoline on hand. They generally are much quieter than gas-powered models and don’t vibrate as heavily during use, which makes them easier on your hands and arms.

There are pros and cons to both two-stroke and four-stroke (also called “two-cycle” and “four-cycle”) gas-powered weed eaters. Fewer moving parts means that two-stroke weed eaters are lighter in weight and easier to maintain than four-stroke models. They generally also have quite a bit more power. However, you will need to mix the gas with oil for two-stroke trimmers. If you’re looking for a quieter model that produces lower emissions, a four-stroke gas trimmer is the way to go. Another benefit: with four-stroke models, no mixing of gas and oil is required. Keep in mind, these models are pricier and generally weigh more than two-stroke weed eaters.

There are gas weed eaters for home use with 20 cc engines and professional models with as much as 50 cc engines, but the majority of gas-powered weed eaters used by the average homeowner have 22 cc to 28 cc engines, which provide plenty of power for tackling overgrown weeds, grass, and brush. When it comes to electric weed eaters, corded models for very light use might have as little motor power as 3 amps or as much as 10 amps, but for typical home use, a motor in the middle of that range is more than sufficient. Cordless weed eaters can use batteries between 18 volts and 80 volts, but again, the middle of that range is generally powerful enough for regular home use.

The 5 Best Cordless String Trimmers of 2023

After researching 60 different cordless string trimmers, we bought the 9 best models on the market today and tested them head-to-head to find out which ones eat up weeds best. We tested their weed slashing performance in a series of comparative tests, cutting through dense patches of grass and burly weeds, and making precision cuts around obstacles. We also measured how noisy each model is, as well as maximum runtime, plus ergonomics and ease of use. To find out which weed eater cut through the competition, which is your best bet on a budget, and which models will work with your existing cordless tool batteries, check out the rest of the review below.

In addition to string trimmers, our team can be seen in the field testing top-tier cordless leaf blowers and the best cordless lawn mowers, among many other electric tools. We’ve tested over 135 electric power tools over the last several years. This gives us unique insight into performance over an entire line of electric tools, so if you’re enticed by the performance of a Makita string trimmer you can check out how a Makita cordless circular saw or chainsaw stacks up before you commit to a brand and its batteries. Don’t forget, of course, about our curated list of the best tools on the market.

Editor’s Note: We updated this revised on November 21, 2022, sharing more info on our scoring metrics.

Best Overall Cordless String Trimmer

Makita XRU15PT 36V

For the cordless string trimmer that does it all exceptionally well, look no further than the Makita XRU15PT 36V. The amount of strength and ability to manipulate even the most resistant weeds and plants is highly impressive. This machine handles detailed work with ease, helping to straighten lawn edges quickly and effectively. Cycling through the three speed settings enables the user to operate the trimmer at its ideal speed for the job at hand. It’s easy to use and comfortable to wield, thanks to its ergonomic grip. In addition, it has a long runtime and isn’t overly loud compared to some other models.

Considering all the attributes, our complaints with this model are minor. However, they are worth noting. For instance, we had to reference the instructions to figure out how to replace the line after it had run out. Once we did, the process was about as easy as it could be. Although there is more weight to handle on this trimmer, the weight is so well-balanced with the ergonomic grip that we didn’t find it to be an issue. If you want a robust cordless trimmer that can handle all of your weed-eating needs, we wholeheartedly recommend the Makita XRU15PT 36V.

Best Bang for Your Buck

BlackDecker LST136

If you’re looking to stretch your dollar with a string trimmer purchase, check out the BlackDecker LST136. We were impressed with this small machine’s abilities as its work stood up to considerably more expensive models that we tested. It’s one of the lightest and easiest to handle, all while running much quieter than some of the top trimmers. The six different operating modes help meet a variety of weed trimming scenarios, and it boasts a healthy runtime.

Unfortunately, this trimmer did get a little overwhelmed when working through very thick weed patches or tough-stemmed plants. It also has one of the larger guards, which can get in the way when making detailed cuts — though it is quite effective at stopping plant and weed debris from getting thrown back at you. Ultimately, if you don’t need a serious beast of a weed-eater, this is one of our favorite budget options for a cordless trimmer.

Another Great Bargain Option

Craftsman V20 Weedwacker

The Craftsman V20 Weedwacker is an excellent, effective tool for keeping your small or medium-sized yard looking great, as well as light-duty brush clearing. It’s lightweight and easy to break out for quick jobs or cleaning up what your mower missed and replacing the spring when it runs out is a simple and easy process. The spool head will receive a lot of abuse as it’s dragged and bumped against the ground, and Craftsman even offers a very affordable replacement.

For bigger jobs where thick grasses and brush have really taken over, the light and relatively quiet V20 Weedwhacker does not have enough power. It does a better job of maintaining the yard rather than transforming it. During testing, the battery life averaged only 35 minutes. Although this isn’t very long, it should suffice for edging along smaller lawns. While the guard effectively shielded us from debris, it was a little too large for detailed work. There are certainly more powerful models with even longer battery life, but we feel this cordless string trimmer is the best choice for the average homeowner on a budget.

Best for Large Areas

Husqvarna 115iL

If you need to clear large areas of vegetation, then the Husqvarna 115iL is a great option to consider. This string trimmer had one of the longest runtimes of all the products we have tested to date, cutting weeds and plants long after other models needed to stop and recharge. The Husqvarna 115iL also offers a slow and fast mode to provide you with an awesome amount of control, whether cutting around delicate objects or clearing wide swathes of grass. It isn’t particularly loud and supplies a decent amount of power when cutting through tougher plants with thicker stems.

On the downside, the Husqvarna can be a bit more cumbersome to use than some of the other products. It has a shorter neck that forced our testers to stand closer to the cutting head than they would have liked. It can also be a pain to hold vertically. The guard is on the smaller side, which is nice when making precise cuts since it doesn’t obstruct your view, but it’s far less effective at stopping flying debris than other products. Despite these flaws, it’s hard to beat the Husqvarna if you have tons of weeds and plants to clear and don’t want to buy extra batteries to get the job done.

Best for Dense Vegetation

Ego Power STA1500 Attachment

If you need a string trimmer that can handle dense plants and grass without a struggle, then it’s worth checking out the Ego Power STA1500 string trimming attachment for the Ego Power Power Head. It is easily one of the most powerful string trimmers of the group and sliced through dense weeds and tall grass without difficulty. It can clear areas that would have stopped other products dead in their tracks. We also think it’s fairly comfortable to use and a compact way to add a cordless string trimmer to your arsenal if you have the aforementioned Power Head.

However, it can be quite a pricey purchase if you don’t already have the Power Head and this trimmer can feel like it has too much power for average yards. The guard didn’t prevent freshly-cut weeds from getting flung back at us, and precision work can be quite difficult. It’s hard to avoid cutting trenches, and the Ego Power STA1500 can be brutal on things like birdbaths, outdoor lights, or the side of your house if you aren’t careful when using it. It’s not for everyone, but it’s a great option if you need heavy-duty string trimming capabilities and plan to get other Ego cordless tools.

Why You Should Trust Us

To say we put each string trimmer through its paces would be an understatement. We implemented 72 individual tests between the 9 trimmers in the review, running each through the same 8 tests to comparatively assess aspects ranging from weed-eating power to noise levels. This allows us to rank each in accordance with its performance in each metric and make special recommendations for the specific needs of homeowners or anyone looking to improve their yard. We paid retail price for each model to ensure an unbiased assessment of these string trimmers.

Our expert string trimmer testing and review team is lead by Michelle Powell and David Wise. Michelle has made a career of evaluating products side-by-side, comprehensively testing, and scoring the smallest details, and differentiating factors on everything from coffee grinders to cordless power tools. Additionally, she also brings extensive lawn care experience to the table. David has formal training as a mechanical engineer with extensive experience in lithium batteries and electrical power systems, which he gained from working on electric vehicles and underwater robots.

Analysis and Test Results

In total, we conducted a dozen distinct tests that we divided among four weighted rating metrics. Each of these metrics — Weed Eating, Ease of Use, Battery Life, and Noise — are weighted proportional to their importance to overall string trimmer performance. The score for each metric is determined by the performance of each trimmer in the tests composing each metric.

Which Cordless String Trimmer Offers the Better Value?

If you’re shopping for a bargain weed eater, then two models stand out: the BlackDecker LST136 and the Craftsmen V20 Weedwacker. These typically cost about half as much — or even a little less — than our top-scoring model, the Makita XRU15PT, and both are solid string trimmers, costing about the same.

The BlackDecker model is a bit more powerful than the Craftsman, and it also has longer battery life. Deciding between the two will likely come down to the size of your yard. Both are lightweight and great for quick clean-up tasks. While neither is up to snuff for professional operations, both are worthy of consideration for the average homeowner.

Which String Trimmer Cuts Weeds the Best?

Weed-eating performance composes the greatest share of a product’s overall score. To rank and compare the weed eating skills of each string trimmer, we looked at the effectiveness of each model when it came to clearing weeds from an area and how each handled dense and hard-to-cut vegetation, as well as how much precision you have for trimming edges and cleaning up small areas.

A pair of trimmers tied for the top spot when it came to eating weeds; namely, the Makita XRU15PT 36V and the Ego Power STA1500 Attachment. Both are exceptionally effective at eliminating weeds, cutting through pretty much any grasses, weeds, shrubs, and bushes we pitted them against smoothly and effectively. They both tackled tall grass and dense weeds with ease, even cutting through burly stalks and stems without showing any sign of a struggle.

The Ego Power STA1500 has just a bit more power than the Makita XRU15PT — almost to the point where the Ego Power STA1500 might be overkill for typical lawn care. While this extra power is handy for the toughest of weeds, it can be difficult to edge or trim precisely. You can angle the head to get into small spaces, but it can be hard to cut near anything delicate without damaging it or cutting inadvertent trenches into your lawn. This excessive power is made much worse by the Ego Power STA1500’s sensitive trigger, making it difficult to maintain a consistent speed.

Although the Makita XRU15PT can’t quite match the Ego Power STA1500 when it comes to raw power, it is superior in close quarters. It has a slow setting and feels very nimble to control, allowing you to make carefully angled cuts or clear areas around sprinklers, lawn ornaments, and other items without damaging them.

The Husqvarna 115iL and the BlackDecker LST136 both performed decently for their string trimming performance. The Husqvarna 115iL was easily sliced through most patches of weeds and grasses, but it occasionally stalled when we tried to tackle dense vegetation clusters.

The Husqvarna 115iL has a comparatively small guard and is lightweight, making it one of the more maneuverable models when it comes to removing weeds from tight spaces. However, it doesn’t have a very long reach, so you need to get fairly close to the end to see exactly what you are trimming.

The BlackDecker LST136 doesn’t have quite as much power as some of the top models, but it can cut through most weeds and plants without issue. It can stall when cutting through the thickest stems and plants, but we rarely found this to be an issue with typical yards.

The lower speed setting also works great for making detailed cuts, but we found that it works better when used in a sweeping side-to-side motion rather than cutting in a straight line. We also like that it is one of the easiest models to replace the cutting line on.

Ease of Use

Like the Weed Eating metric, Ease of Use also constitutes 30% of the total score for each cordless string trimmer. Here we compared the weight and guard design of each trimmer, as well as how comfortable and balanced they are to hold. We also compared the ease of replacing and feeding the line and noted if there was a shoulder strap attachment.

The Makita XRU15PT 36V again earned the top score in this metric. It is exceptionally well balanced, with the battery end of the trimmer only slightly heavier than the head, making it easy to carry one-handed and to wield through fields of grass. The molded, ergonomic grip makes it easy to keep a good grip without working too hard. We also liked the guard on this model because it doesn’t detract from your ability to do precise cuts while maintaining an equivalent degree of protection. The Makita XRU15PT includes a shoulder strap attachment as well.

This trimmer employs a bump feed to dispense more string, but it’s a little more difficult to replace the string than some of the other models. There aren’t alignment indicators on the spool, which forced us to consult a manual, but it was straightforward once we became familiar with it. This minor drawback should only be an issue once or twice, after which you’ll get the hang of it.

The Ego Power STA1500 Attachment by Ego, Craftsman V20 Weedwacker, and the BlackDecker LST136 all scored well regarding convenience and ease of use. The Ego Power STA1500 has a very straightforward mechanism for adding more line. The line threads into the part you remove, so you don’t need to be as careful about making sure everything lines up properly when you reassemble the head.

The Ego Power STA1500 has a bump feed to dispense more line, and we found it quite comfortable to carry. It has a cushy handle and is very well-balanced, but the guard didn’t seem to be as effective as other models, with debris flying back at us on a semi-regular basis depending on the type of cut. However, this model does not have a shoulder strap attachment.

The BlackDecker LST136 and Craftsman V20 Weedwacker are both very simple to pick up and use right away, scoring quite equally in their user-friendliness. Both are very lightweight, making them easiest to handle and finesse in tight areas around obstacles. They’re fairly comfortable to use for long periods, even without a shoulder strap, and their grips are easy to hold. Line replacement is also very straightforward.

Battery Life

Our next metric focused on the battery system of each string trimmer, and this accounts for 25% of each product’s final score. We based the bulk of this score on the maximum runtime for each product and awarded extra points to models with different speed settings because it allows you to maximize the battery life by throttling down when extra speed is unnecessary. We measured the runtime for these weed eaters when they weren’t actually eating weeds, so you’ll probably get lower numbers if you’re chewing through dense vegetation or particularly stubborn weeds.

The Greenworks 14-inch 40V, the Makita XRU15PT. and the Husqvarna 115iL all tied for the first place position in this test. These all lasted for around 90 minutes before the batteries gave out, and they each have a series of different speed settings.

Petrol/Gas vs Battery Outdoor Power Equipment. Ego Vs Stihl

Performance dropped a bit with the remaining trimmers. The Snapper XD 82V clocked in at 48 minutes of runtime and has two operating modes, but we didn’t notice a huge difference between the two modes except for the amount of noise produced. The low power mode still seems plenty powerful to chew through pretty much anything with the line we used. However, the difference between the two modes might be more noticeable with a different line.

Noise

Our final metric focused on the amount of noise that each cordless string trimmer generated while in use. To determine scores, we used a sound level meter to measure the noise from each cordless string trimmer at a distance of 3 feet and had a panel of judges rate how annoying the sounds were at the same distance and from 50 feet away.

The Makita XRU15PT took home the top spot in this metric. Our meter recorded 85 decibels when this model was in use. We noticed, however, that it has a particularly high-pitched whine on startup that is rather irritating. The Craftsman V20 Weedwacker registered 84 decibels, but also suffered from an annoying, high-pitched whine.

The BlackDecker LST136 trimmer registered sound levels of 85.9 decibels on our meter when it was placed about 3 feet away, though we did find that it has a bit of a high-pitched whine.

The Husqvarna and the Snapper both followed. We recorded sound levels of 88.5 decibels for the Snapper XD. The Husqvarna is very loud on startup, registering 105 decibels, but this quickly drops to around 95 decibels while operating the string trimmer. The Snapper has a whine that can be quite grating, while our judges believe the Husqvarna’s sound is one of the least annoying; it’s just loud.

Conclusion

Whether you need a powerhouse trimmer to tackle the toughest weeds or a lightweight budget model for some minor yard maintenance, we hope this analysis and review has helped you find the perfect cordless string trimmer to match

The Best String Trimmers

A fter two months of edging lawns, trimming grass and relentless weed destruction on a ten-acre orchard, we’ve picked the BlackDecker – LST136W as the best string trimmer for the average sized home lawn. Perfect for edging your lawn and even for cutting grass on uneven terrain, BlackDecker’s award-winning 13-inch trimmer is light and easy to use but still has plenty of power. For larger field jobs, we like the Ego – Power 1502-SF.

The 4 string trimmers we tested

BrandPriceCutting WidthCutting Ability# of StringsTested Run Time (Minutes)

Best overall: BlackDecker – LST136W

The BlackDecker – LST136W is a compact, lightweight but powerful trimmer that will be ideally suited to most home edging and trimming needs.

Weight is a big consideration here: we liked how easy it was to carry this trimmer around. The fact that it can be collapsed to a smaller size for storage is a great bonus. The other tools fold or come apart, but that makes for an unwieldy package.

None of the conveniences would be a worthwhile trade-off if this trimmer couldn’t keep up with the cutting tasks, but BlackDecker managed to hit a sweet spot for efficiency and power. The motor tackled thick, overgrown grass that bogged down even the big Ryobi trimmer, and it managed to cut heavy stalks (like the pictured fig-tree shoots) better, too.

If you’re dealing with household chores like trimming lawn edges and cutting weeds around flower beds, this trimmer does amazing work given how light it is.

This is all the trimmer most people will need in a lightweight, high-performance package. Perfect for city lawns and gardens, it also out-cuts some bigger models if you take it out to the back 40.

Even better, there’s an easy-to-use speed dial that will vary the amount of juice the motor is using: if you’re just trimming a bit of grass or light weeds, you can turn it down and get even longer runtime from the battery. We ran all our tests with the power cranked up to full and were still satisfied with the battery capacity, but it’s nice to know that you can go for longer if you’re not pushing the performance envelope.

There are definitely jobs that this trimmer is too small for, but the motor and battery aren’t really the limiting factor. If you’re working around sharp stones or tough plants like vines, then the 0.065-inch trimming line will disappear quickly.

With unexpected line breaks, and it was sometimes frustrating having to wait for the BlackDecker’s automatic feed system to pay out more line. We even bypassed it a few times by opening up the spool and unwinding a few turns manually after losing a big chunk of string. Bigger machines with 0.080-inch line won’t last too much longer when dealing with tough material, but they are designed to quickly feed out more line after it breaks.

Probably the biggest disappointment of this machine is the length of the shaft and the difficulty of attaching a standard shoulder strap bracket. If you’re much taller than six feet, you might be annoyed by how far you need to stretch your arms to reach the ground with the optimal cutting angle.

Adding a shoulder strap helps, since your arms aren’t carrying all the weight anymore. Since the shaft of this tool is too thick for a “universal” strap bracket, we had to improvise an attachment point; it’s not pretty, but it works. If you’re shorter in stature, the adjustable-length shaft is very easy to set at exactly the right length for good posture and easy work.

• The BlackDecker – LST136W is the lightest trimmer we tested and collapses neatly for easy storage.
• The weight savings don’t cost you much in terms of cutting power, and we were impressed with how capable this 13” trimmer is in the field.
• 33 minutes of working time is close to average, but there’s a handy power dial feature to save power when you’re only doing light cutting.

Best for heavy work: Ego – Power 1502-SF

If you scoff at the term “lightweight” and are looking for a battery-powered trimmer to replace a gas model, Ego’s Power ST1502-SF is made to fit your needs.

With a higher-voltage “Power” battery system that pumps up the wattage available to its motor, Ego’s trimmer also uses commercial-grade 0.095-inch line that will cut heavier material better than any of the other electric trimmers we tested.

For overgrown grasses and big weeds: Ego’s 15-inch trimmer is quiet and powerful. Its commercial-grade line effectively cut through thick growth better than any of the other electrics we tested.

The available power comes at a price: with only 36 minutes of runtime despite the massive 2.5 amp-hour battery, this machine is just barely viable for big jobs on an acreage. (This trimmer runs at a higher voltage than the others, so the battery has more cells inside.) It’s heavy enough to make your shoulders and back sore the first couple of weeks you use it. That said, this is lighter than the Ryobi 15” trimmer or a gas-powered model, and a shoulder strap is a good idea anyhow.

Fortunately, the battery charger got the same treatment as the rest of the machine, with an integrated cooling fan and beefy power supply. The charger reliably refilled the 2.5 AH battery in less than 45 minutes. That’s impressive even compared to the Greenworks charging system, which only had to refill 2.0 AH and took an hour.

We don’t really have anything bad to say about the Ego trimmer, and it was far more powerful than the Ryobi’s competing model, but we found that for city lawn work it was a bit overkill.

You can definitely do most of the jobs this trimmer will do with the BlackDecker, and our top pick has a wire guide and rotating head for easy edging jobs. The Ego’s hand grip lets you hold the trimmer sideways to do edging, but it doesn’t feel like a purpose-built solution the way our top pick does.

• The Ego – Power 1502-SF has a 15-inch cutting head with commercial-grade cutting string and a 36-minute runtime.
• Ego has dropped the gauntlet and puts gasoline-powered toolmakers on notice. There are still pros who don’t have the option of waiting for a battery to charge every half-hour, but for the rest of us, this is the best big trimmer to buy.

Other products we tested

Greenworks – 2101602 G-MAX

Greenworks has released the 2101602 trimmer as part of their G-MAX system, and while it doesn’t make top grade, it’s a very capable machine.

The biggest hindrance to this trimmer is weight and ergonomics. While the BlackDecker tool weighs in at a very slim 6.8 pounds, Greenworks only managed 7.8, with a smaller battery, and with a drop in cutting power.

The performance of this trimmer is acceptable for most situations: the line only reaches 12-inches in diameter compared to the BlackDecker’s 13-inch, but Greenworks has two lines spinning at the same time as the big 15-inch trimmers do.

We felt that they were on fairly equal footing in terms of cutting power if you dial back the BlackDecker control wheel to 85 percent power, which roughly matches any difference in runtime, too.

If you don’t think you’ll ever want to cut anything heavier than grass, the Greenworks will save you some money and charges a bit more quickly, but we really liked the option of bumping up the power just a little bit with BlackDecker’s system.

The one case where we’d recommend this trimmer over the BlackDecker is if you’re much taller than six feet. The Greenworks trimmer’s longer reach makes it a bit easier to find a balanced handle position, and mounting a “universal” shoulder strap isn’t as tricky.

Ryobi – RY40220

The Ryobi line won top spot in Consumer Reports’ roundup, and The Wirecutter liked this one enough to give it runner-up pick.

The Ryobi – RY40220 trimmer gives you a ton of options. If the first thing you’re looking for is a tool system that will let you do hedge trimming, roto-tilling, and leaf blowing with a single battery and motor module, then it might be worth considering.

Sadly, Ryobi’s lawn tools aren’t compatible with their cordless shop tools. Ryobi’s 40-volt system doesn’t offer nearly the same power as the Ego 56-volt system, either, nor is it significantly cheaper.

On the whole, this trimmer was pretty disappointing. It’s loud: not nearly as loud as a two-cycle gas engine, but far louder than any of the other electric trimmers we tested. It’s also heavy, about one pound shy of a gas-powered trimmer and two pounds more than the Ego (despite that bigger battery).

In thick, tall grass or against stout weeds, the Ryobi just didn’t seem to have enough power to keep up. The worst-case scenario for this particular tool seems to be thick grass: clumps of tall quackgrass that BlackDecker’s lightweight trimmer buzzed through easily seemed to be too much for Ryobi’s motor or drive system.

On vines and thick stalks like the fig saplings pictured above, the motor would slow down enough that the cutting string started wrapping instead of cutting, and we had to move much more slowly and more deliberately to cut weeds efficiently with this trimmer.

Those tough-cutting situations are not great for any weed whackers since tough stalks and vines will also start wearing and breaking your trimmer line. We’d prefer to use up the line more quickly, though, if it means we can get through occasional patches of heavy weeds without bogging down.

Ryobi’s bump-feed system works well, with slightly more consistent re-loading than Ego’s, so it’s not a total failure as a serious tool. Without more power to cut through tough spots, though, the refinement seems a bit of a waste.

Ryobi has also faced some criticism in customer reviews over the batteries they sell. Some users are reporting that their batteries won’t charge anymore after a few months. There are some unrealistic expectations in the Home Depot customer reviews: cordless lawn tools shouldn’t be expected to run for more than 30 working minutes. Failing to charge, though, is a serious problem.

We haven’t had any problems with our Ryobi battery yet, and we didn’t see the problem mentioned in the other major reviews, but we’ll update if ours kicks the bucket.

How we selected

First, we looked at reviews and customer feedback for the top-selling trimmers on the market. We also covered the top-placing trimmers from publications like Consumer Reports and the Wirecutter.

We reviewed battery-powered trimmers, because, let’s face it, two-stroke gasoline engines are noisy, smelly, and expensive. Gas trimmers earn a place on the trucks of professionals with top power and long run-times, but most homeowners will be happy with clean, quiet and simple battery power.

While we set out to test battery-powered trimmers, we also used some other tools alongside our test lineup for comparison. We included a gas-powered STIHL – FS 70 R in our tests to see how the electric trimmers compare to the industry-standard workhorse that’s already doing the heavy work for landscapers and ranchers. We also purchased and used a plug-in edge trimmer and trencher, the BlackDecker – LE750.

We picked a set of top-ranked trimmers in two size categories: trimmers with 15-inch cutting heads as well as compact 12-to-13-inch machines. We bought from brands with good reputations for warranty coverage that are available at major retailers. (In comparison, many commercial-grade brands like STIHL are only available through a dealer network.)

When selecting a trimmer from Ego, we picked the best-priced package at the time, the 1502-S. Ego’s model numbers are a composite of the trimmer model, battery size, and extra features. This kit includes a 2.5 AH battery and the 1500 trimmer with “split-shaft” folding for storage. This review has a table that explains the differences in kit accessories and features.

There’s a new model that has replaced the.S, called the.SF, with a “Rapid reload” head in addition to the split shaft. Everything else about the kit is the same, so we’ve updated links in this review to point to that kit instead.

How we tested

In addition to testing for lawn-duty use in the city, we sent this lineup of trimmers to an avocado orchard in southern California. The trimmers arrived at the ten-acre grove just in time to begin work cleaning up all the weeds that had sprung up after a fall fertilizer application. Our testers cut weeds ranging from mundane dandelions and crab grasses up to the imposing four-foot-tall horse thistles.

The orchard already uses a selection of gas-powered trimmers, mostly mid-size STIHL models like the FS 70 R. We’ve included direct comparisons to the STIHL where it makes sense, but as context rather than as a purchase recommendation: we believe that most home users are going to be happier with a cordless electric trimmer.

Weight

As mentioned in our section on features, none of these trimmers were supplied with a shoulder strap, but they really should be. We tested each model without a strap for a few weeks before ordering a generic strap from Amazon.

These trimmers are quite light compared to the gas-powered engines that professional landscapers are using for hours at a time, but that doesn’t mean they’re easy on your shoulders and back. If you’re only planning to do quick touch-up trimming, the BlackDecker – LST136W is not too bad without a shoulder strap; for any other purpose, get a strap.

Cutting ability

This was one of the trickier values to test for. Each of these trimmers will cut grass easily, but the upper limit of cutting capacity is harder to define.

We measured the biggest weed stalks that could be cut cleanly by each trimmer. We tried to bog down the trimmers in extra-dense grasses. We even skirmished with some materials like saplings and vines that are just too tough to cut effectively with string trimmers.

The wattage rating here is a value derived from the nominal capacity and voltage of each battery system divided by how long the trimmers run before shutting off. Between batteries with the same capacity and voltage, a shorter run-time means more wattage is being pulled by the motor.

The chart above rates each tool on a scale of five based on how effectively it cut, but note that the smaller trimmers use a thin line that disappears quickly if you’re cutting tough woody material.

There are a lot of similarities between trimmers of the same size, but each manufacturer has taken its own approach to find a balance of power, battery life, and weight.

The Ego trimmer has impressive power, ripping through all but the very toughest weeds. The other trimmers stopped cutting green leafy weeds when stalks got bigger than 0.45 inch, though the Ryobi trimmer often failed on anything bigger than 0.35 inch.

Gas trimmers probably have enough power to cut through very thick material, but the trimming line will usually start to wear away before you reach the limit of engine power.

Line advance

The different systems used to release more cutting string have their strengths and failings, but we ranked them here based on how easily and quickly we could get back to cutting at full speed after a rock or vine ate away at our trimmer string.

The automatic-feed systems are okay for general use, but for cutting in the field where string sometimes goes quickly, we preferred a system like the bump-feed that gives some control over how much line is fed out and when.

Battery tests

We timed how long each trimmer will run under the same conditions, with the motor running constantly and cutting in dense grass and weeds.

As you can see from the charts, run time tracks pretty closely with the size of the battery and the amount of power the trimmer puts into cutting. The more work the tool does spinning the trimmer line, the shorter the battery life.

We also timed how long it takes to recharge the batteries with the included chargers; this will be a more important detail for some buyers than others.

The most surprising result is the Ryobi system; the short run-time on a high-capacity battery means it’s pumping a lot of watts through its motor. The fact that this trimmer also suffered poor cutting performance suggests an inefficiency in the drive shaft system that allows changing to other tool types. (It’s certainly the noisiest trimmer, and more noise is never an indicator of an efficient electric drive system.)

As noted previously, we’re using a nominal advertised power rating for the STIHL 2-cycle engine (0.9 kilowatts) that seems accurate. It has far more power available than the battery systems, and every fill of the 11.5 oz tank will give you about 34 minutes of run-time.

Who needs a string trimmer?

While a lawnmower is basically essential to the health of your lawn, string trimmers and leaf blowers are a bit more of a luxury. You’re keeping your grass at the right length, what’s left to do?

String trimmers are great with grass and weeds in all of the locations where a mower can’t help. Does your lawn have a corner where your mower won’t fit? Mow it with a string trimmer. A patch of weeds sprouting behind your trash cans? The string trimmer will take care of those, too. Want a clean edge between your grass and driveway? A good string trimmer will make edging easy.

Unless you own a home in a desert or polar region where nothing grows, a string trimmer can probably make your yard work easier.

Because the string that’s doing the cutting is flexible, you can cut right up to a tree or planter or post and not worry about damaging anything. The string will only cut through soft fibrous material like green plants, barely leaving a mark on big trees, concrete or metal. You should still be careful not to hit young trees and flower beds, of course, but it’s much easier to safely get close than it is with a mower.

String trimmers are even more popular on acreages and farms where hillsides and rocky patches make mowing impossible. Even in dry climates where grass landscaping and mowers are scarce, string trimmers can take care of the weeds that pop up.

If you’ve got a lawn that your mower covers perfectly and you don’t mind pulling your weeds by hand, you might not need a string trimmer. If you’ve got a bigger yard, though, there are almost certainly areas a string trimmer can help.

How to edge-trim your lawn

While a lawnmower trims grass that stands up in the air, it won’t do anything about the grass that lies flat or bends over and spreads onto your walkway or driveway. A trimmer can cut those leaves in a precise line along the edge of your lawn.

Edging your lawn with a string trimmer is quick and easy. First, turn the trimmer so it cuts up and down instead of parallel to the ground. Most have a rotating shaft or a multi-position handle so you don’t have to contort your upper body while holding the trigger in this position.

Walk the trimmer head down the edge of the lawn. Many trimmers have some sort of guide or another indicator that helps you track where the cutting string will hit. The rapidly spinning string will slice through any blades of grass that cross over onto your sidewalk and leave a clean edge. Typically the guide is set so that you dig a neat, narrow trench into the dirt along the edge; if you just want to cut the grass, you’ll have to lift the trimmer a few inches and hold it steady while you walk it along the line.

For Edging and Trenching: BlackDecker. LE750

This is an edger for people who want straight, clean, well-defined edges. It won’t mow in the corners like a string trimmer, but it will cut small trenches to run wires for backyard lighting projects.

Edgers like the BlackDecker – LE750 are built for edging and trenching only. A tool like this uses a solid metal blade rather than a flexible string, and this has a few consequences. For one, the whole tool is far more intimidating, and it can’t cut weeds or mow the tricky spots around trees. The edger can do jobs like trenching that aren’t possible with a weed whacker, and the wheels and guides help you cut a very straight and even edge. Think of it as a circular saw for your sod.

Even for edging, we prefer string trimmers over dedicated edgers, because they’re easier to use on curved edges or uneven ground. It’s still tricky to follow a curve perfectly, but if you lose track with a string trimmer you won’t hear the terrifying sound of a metal blade scraping against concrete.

The best trimmers make it easy to switch between horizontal cutting and edging jobs, and our top pick, the BlackDecker, is no exception. You simply hold a button on the shaft and twist the cutting head to go from grass trimming to edging quickly and easily.

Types of trimmers

Gasoline

This is the type of string trimmer you’ve seen working beside roadways. Two-cycle gas engines have all the power you could ask for and can run six hours on a gallon of gasoline. They’re loud, though, and require extra maintenance. There’s also the trouble of mixing, storing and filling the oil-gasoline mix required by two-stroke engines.

We’re not trying to dissuade anyone who needs a gas trimmer from buying one: our test partners still rely on a few reliable and powerful gas trimmers that see all-day use and perform well. For an average-sized yard, though, gasoline is overkill.

Plug-in electric

We didn’t test any corded trimmers. They have a great price-power-weight ratio, but the cord is frustrating to work with. The specialized edger/trencher we tested is a plug-in model, and it has great power, but if you’re doing anything other than straight, slow lines close to your house the cord isn’t worth it.

Battery-powered electric

Cordless electric trimming is definitely the most pleasant experience of all. These trimmers are much quieter than a gasoline-powered trimmer, and you’re free to move quickly and efficiently around your yard.

The big downside to cordless electric is capacity: battery packs make a painful trade-off between power, run-time, and weight. Lithium-based battery technology is getting better every year, so the current generation of tools is widely regarded as a worthwhile compromise if you’re doing small jobs.

Battery life is up to around half an hour for most models, long enough to finish trimming around a house and small lawn without needing to stop for a charge.

Important features to consider

Power

In the world of cordless tools, manufacturers aren’t required to list specific power-draw specs on their tools the way they are with tools you plug into the wall. Makers do tell you about battery voltage, but that’s only half of the electrical story (volts x amps = watts).

Without a rating of the current drawn by the motor, we have to make guesses or extrapolations based on other numbers, like run-time and battery size. Gasoline engines do have a nominal watt power rating (since watts and horsepower are two different ways of measuring power, the rate work is done) and manufacturers like STIHL tell us what to expect from their engines.

We’ve made an estimate for the wattage used by each of the cordless tools. All of these numbers are for available power from the battery system and don’t take into account any waste from inefficiencies of the working machines. Our “cutting power” test scores give a better idea of what each machine can really do with that power.

A balance between power and noise

Many professionals rely on two-stroke gas trimmers for all-day landscaping work, and they might be the right tool for your job. That said, the noise of a two-stroke gasoline engine requires hearing protection and will likely disturb your family or neighbors if you like to do yard work in the morning. Some electric trimmers make a bit more noise than others, but none of them come even close to the loudness of a two-stroke engine.

Battery size

Batteries are typically sold with a capacity listed in amp-hours, literally the number of hours the battery will be able to send one ampere of electrical current to the motor. As noted above, these tools don’t list how many amps they draw from a battery, so we’ve done the dirty work with real-world tests of working time.

Cutting width and line size

The advantages of cutting a wider swath are both efficiency and power. For example, the difference between 13 inches and 15 inches might not seem like a lot, but if you’ve got large weedy patches to attack, the extra cutting with each pass can definitely add up over time.

The bigger advantage to a wider swath is in cutting power. A longer string means that, for the same engine speed, the tip of the cutting line will be moving faster, moving at (for our example) 16,000 feet per minute instead of only 14,000.

The difference between a 13-inch cutting head and a 15-inch head is about 15 percent in both the cutting area and the speed of the string, but there’s more. When you add the fact that a bigger head can take a line that has a 0.080” diameter instead of the skinny 0.065” string in a typical smaller machine, the extra mass makes for yet another 23 percent increase in the force that goes into chopping weeds. (Some big trimmers can load 0.095” or 0.1” line for even more power, and 0.095” is a typical diameter for commercial work where tough weeds are expected.)

Extra force means more electricity is needed from a battery pack, so you’ll see diminishing returns if you’re more concerned about run time than cutting a wide swath through dense weeds.

We’re pretty sure that this is the flaw in Ryobi’s design with the 40220: the motor just can’t draw enough current from a 40V battery to get the big 0.08” string going quickly enough. Our top pick from BlackDecker uses 0.065” string, but the slightly newer LST540 seem to have problems with its heavier string just like the Ryobi.

If you’re even considering running the trimmer for more than one battery charge (about half an hour) in a day, the extra width and power of a bigger trimmer with a high-voltage battery is probably worth it (and you might consider gas). If you’re mostly edging and you keep up with garden weeds so you never see half-inch stalks, then a 13-inch trimmer should do the job without extra weight or expense.

String feed system

There are a few ways to get more cutting line out when rocks, sticks, and concrete wear down or break the string:

Automatic feed: Popular on smaller trimmers, this feature is included on our top pick BlackDecker as well as the Greenworks trimmer.

This system tries to keep your line at just the right length by letting out a small amount (usually about ¼ inch) every time you stop and restart the trimmer. The line never gets too long, because a small blade chops off any excess line as it spins.

This is handy, but it can waste line if the mechanism is too generous, and can be frustrating to work with if the spool is stingy. (If you burn through a bunch of string cleaning up around a sharp-edged brick planter, for example.)

Some newer trimmers use a hybrid manual/automatic system that will pay out more line when you push a button while the trimmer is running, but this wasn’t available on the top-ranked trimmers we tested. Manual feed: This feature lets you stop the machine, pick up the trimmer head and press a button to pull out more string. This takes time, but you can get very close to the maximum allowed length (determined by the length-trimming blade mounted on the guard) to reduce wasted line.

The trimmer from Greenworks is the only one we tested that has a manual-feed bypass for its automatic system. Bump-feed: This lets you use a spring-loaded clutch system that will release more line when you “bump” the bottom of the trimmer head on the hard ground while it’s running. This is the system used on the 15-inch-width trimmers we tested, from Ryobi and Ego.

This takes some getting used to, but if you’re working around rocks, sticks, and concrete that quickly wear out your trimmer line, it’s a very fast way to get back to the job. Most commercial-grade trimmers use a system like this.

Fixed-line: This type of trimmer head is sometimes an option, but we didn’t pick any models with this style. Rather than a spool that feeds out line as it’s used up, a fixed-line head just holds one piece that starts out at exactly the right length and needs to be manually replaced when it wears down.

A shoulder strap

None of the models we tested came bundled with a strap, and we tested each of them without one, but if you’re going to be running a trimmer for more than ten minutes at a time you owe it to yourself to use a support system of some kind.

Essential Accessory: Arnold. Universal Trimmer Strap

The universal trimmer strap from Arnold is basic, but it’s a huge relief to shift the weight of the trimmer onto your core muscles.

Aftermarket straps are plentiful and cheap; we tested the Arnold Universal Trimmer Strap. It works perfectly on all the models except our top pick: the bracket included with this strap won’t quite fasten around the thicker shaft on the BlackDecker tool. The strap itself can clip on various parts of the handle, though, and we didn’t have any problems using it; the BlackDecker is also a trimmer that’s light enough not to need a support strap as badly as the others do.

The shoulder strap attachment bracket should sit right at the balance point of the trimmer. After you adjust the length of the strap to get the trimmer at a perfect height, you can almost work one-handed.

There are more elaborate strap and harness systems available to help balance a heavy commercial trimmer. The trimmer will rub against your hip if you’re supporting it with a strap, so the heavy-duty harnesses include some kind of shield to fend off bruises and grass stains.

The bottom line

Trimming grass and weeds around your lawn is one more step in a mowing routine that can really make the difference between a lawn that’s merely cut and a lawn that looks carefully maintained.

BlackDecker’s – LST136W is a tool designed with home lawn care in mind, and it has just the right set of features and performance to excel in an urban environment. Striking a good balance in power, weight, cost, and battery capacity, this is a single-line trimmer that can keep up with your lawn-care needs.

At less than seven pounds and with enough battery capacity to get you through a weekly trimming job, this is a great tool for urban lawn-care.

Top 10 Best String Trimmers for 2023

String trimmers, also known as weedeaters, weed wackers, or weed trimmers, are designed to spin a line fast enough to cut grass. Finding the best model can be subjective, as different people may have different preferences. We asked our team of experts to provide their recommendations for a range of users, from homeowners with small lawns to professional lawn care crews.

Editor’s Note: Check out our best battery-powered string trimmers article for our top picks among all battery-powered models.

What We Look for in the Best String Trimmer

Battery vs Gas vs Electric String Trimmers

When selecting a string trimmer, it’s important to consider factors such as performance, convenience, and cost. Gas-powered string trimmers offer the most power. Their excessive noise and fuel requirements and need for annual maintenance make them less desirable for some. Gas string trimmers also produce engine emissions that many users want to avoid or curb where possible.

On the other hand, battery-powered string trimmers operate more quietly. They also produce no emissions and require only minimal maintenance. They do tend to cost more upfront due to the of lithium-ion batteries and runtime is limited by the battery capacity. When you exhaust the battery power, recharging also takes a lot more time than filling up the tank!

Electric string trimmers are generally cheaper and have unlimited runtime, but may not be as powerful and require the use of an extension cord.

String Trimmer Line Size

The thickness of the line used in a string trimmer typically falls within the range of 0.080 to 0.105 inches, although options exist outside of this range. We’ve even seen a cheap string trimmer that uses zip ties. We definitely don’t consider this a recommended practice!

The diameter of the line in a string trimmer affects its performance and suitability for different tasks. Smaller diameter line causes less damage to objects it strikes, such as siding, wood, or pipes. It can also provide longer runtime on battery-powered string trimmers. However, they may not cut through tough grasses as effectively. Larger diameter lines can be more destructive and less energy efficient but may be better suited for heavy-duty use in tough conditions.

For smaller lawns, 0.080-inch line keeps grass under control and minimizes collateral damage, while also providing good runtime on battery-powered string trimmers.

We recommend 0.095-inch line as a good all-around option. It cuts quickly and moderates the risk of damage. Most high-end and all professional-targeted cordless string trimmers support this size line.

For professional crews, farm and ranch use, or large properties, 0.105-inch line may be the best choice for quickly clearing overgrown grass and handling thicker stalks. This size may require a 30cc engine to effectively use, however. On battery-powered models, only the high-end products that target pros can handle this size.

Cutting Swath

The cutting swath of a string trimmer refers to the diameter of the area that the line can cover. For smaller lawns, a 13-14 inch cutting swath is sufficient, especially when using a walk-behind mower that can get close to landscape edges. A 15-16 inch cutting swath is a good all-around size, while professional crews and those with large properties may benefit from a 17-inch or larger cutting swath.

If you run a gas trimmer and want to ditch the guard and run your string at 24 inches, a battery-powered solution may not provide the speed or run time you expect.

Weight

The weight of a string trimmer is an important factor to consider, as heavier models can be more difficult to maneuver and may cause strain on your back. Shoulder straps can help with this, and some cordless models include them.

When selecting a string trimmer, we recommend choosing the lightest model that has the power to handle your toughest jobs. You also want to ensure the build quality and warranty meet your expectations.

Vibration

Vibration is a factor that has gained attention with high-performance cordless string trimmers. Gas engines generally produce more vibration than battery-powered tools. Still, cordless and electric trimmers vary significantly from model to model.

In some cases, placing the motor in the head of the string trimmer can help reduce the vibration caused by the drive shaft. This also moves some of the weight away from your arms.

Features

Gas and AC electric string trimmers typically don’t have many extra features, but brushless battery-powered models may have a few options that could influence your purchasing decision. These may include:

• Attachment capability (all power types with the motor or engine at the operator end of the tool)
• Multiple speeds (including automatic modes)
• Reverse rotation to untangle tall grass
• Faster throttle-up
• Compatibility with other lawn care equipment and power tools

Value

We prioritize value in our purchases and want to help you get the most for your money. When selecting a string trimmer, it’s not just about finding the cheapest option, but rather finding one that meets your top priorities while staying within your budget. Keep this in mind as you go through our picks.

Best String Trimmer Overall for Professionals

Echo X-Series String Trimmer SRM-2620T

There is much debate about the best overall gas string trimmer, but the Echo X-Series SRM-2620/2620T model keeps showing up in our lists. The only difference between these two models is that the “T” version has 2:1 high-torque gearing, which we recommend for professional use.

The 25.4cc engine in this model strikes a good balance in terms of power, weight (12.5 pounds dry), and ease of starting. Its power-to-weight ratio is among the best available. It also has a solid runtime with a fuel capacity of just under 21 ounces. The Echo SRM-2620T is highly maneuverable and has a narrow guard that provides good visibility on its 17-inch cutting swath. Additionally, the Speed-Feed 400 head makes line changes easy.

Best String Trimmer Overall for Homeowners

EGO PowerLoad String Trimmer with Line IQ ST1623T

Homeowners can confidently switch to a battery-powered string trimmer if it fits within their budget. EGO produces some of the top-performing and lowest-vibration string trimmers on the market. We know as we’ve put our hands on every single one of them.

One standout model is the EGO ST1623T. It features PowerLoad technology that makes it easy to load new line. Simply thread the line to the halfway point in the head, press the PowerLoad button, and it automatically winds. The ST1623T also has Line IQ, an automatic feeding system that keeps the line at a consistent 16 inches without the need to constantly bump the head. It works really well. Finally, with a telescoping carbon fiber shaft, the EGO ST1623T makes for a top choice for homeowners of any height.

Price: 329 with 4.0Ah battery and charger

Best Gas String String Trimmer

STIHL FS 91 R Professional String Trimmer

While the Echo 2620T remains our pick for the best overall professional string trimmer and gas model, a close second is the STIHL FS91. This 16.5-inch trimmer features a 28cc engine that has plenty of power for trimming grass. You can also easily use this tool for farm and ranch work. Despite its impressive power, you can easily manage the FS91 with a dry weight of 12.1 pounds and a fuel tank capacity of 24 ounces.

One major advantage of owning a STIHL product is the company’s extensive dealer and service network. If you need regular maintenance or if your trimmer needs repair, you can get it taken care of quickly.

Best Cordless Battery-Powered String Trimmer

Husqvarna 520iLX Battery-Powered String Trimmer

The Husqvarna 520iLX is a cordless battery-powered string trimmer built for professional and large property use. It performs well on lawn grasses and has a reverse direction button to release tangled grass or direct clippings to the proper side when edging along sidewalks.

One of the standout features of the 520iLX is its lightweight design. The bare trimmer weighs just 6.6 pounds, and adding a battery keeps it under 10 pounds. It is one of the lightest and most well-balanced trimmers available that targets professional users.

In addition to its lightweight design, the 520iLX has extremely low vibration and a noise level that, while not the lowest we have tested, has a more palatable tone than other models.

Best Electric String Trimmer

Ryobi Attachment Capable Electric String Trimmer RY41135

If you prefer electric power, it is possible to find a string trimmer that performs well. In a rather close competition, we feel the Ryobi 10-amp, 18-inch string trimmer outperforms the Kobalt model of the same size.

Both trimmers have the same power and cutting swath. Both also work as attachment-capable tools and are lightweight. However, the Ryobi RY41135 electric string trimmer has an easy-load head that makes changing the line less frustrating. This gives it the edge as our best electric string trimmer pick.

Best String Trimmer for Large Areas

Echo X-Series Brushcutter SRM-2620U

For large areas where mowers can’t reach, the best string trimmer should have excellent runtime, a large cutting swath, and, in our opinion, a bike handle design. The Echo SRM-2620U brushcutter, which is based on our top overall professional pick, meets all of these requirements.

It has the same engine and trimmer head but replaces the D-handle with a bike handle and harness for better support during extended use. This design offers the same performance as the original model but the handle design makes it easier to manage over longer periods of time.

Best String Trimmer for Overgrown Areas

Husqvarna Brush Cutter 545FR

When dealing with areas that have a lot of overgrowth, it’s important to be patient and choose a string trimmer that is capable of using a brushcutter head. We also recommend going with a larger engine for this type of work. The Husqvarna 545FR represents our top pick for the best string trimmer for overgrown areas.

The trimmer houses a powerful 45.7cc engine that can handle a trimmer head, grass blade, or brush-cutting blade. It efficiently clears both tall grass and saplings. This string trimmer also comes with a comfortable harness, vibration-dampening bike handles, and easy starting, making it a reliable choice for tackling overgrown areas.

Best String Trimmer Line

Echo Black Diamond String Trimmer Line

I may start an argument in this section, but I recommend Echo’s Black Diamond line as the best string trimmer line for most applications. Its density, combined with a sharp-pointed square twist, makes it more effective at cutting for its size compared to many basic lines. You can purchase it in 0.095-inch and 0.105-inch sizes, making it a great choice for almost any trimmer, including most battery-powered options.

The one exception? Auto-load/feed trimmer heads like those found on the EGO Line IQ trimmer and similar models. On those tools, something. about the twist on this line makes it bind before fully leaving the spool. It also often binds on loading after a time. The simple solution is to grab a line with a less aggressive outer shape. Round line or something with a less aggressive twist should work fine.

Best String Trimmer Brand

This section will likely spark an intense debate. When it comes to string trimmer brands, STIHL, Redmax, Echo, and Husqvarna consistently float to the top of the list. Additionally, all-battery brands like Milwaukee and Greenworks Commercial also have a growing presence in the marketplace.

In our opinion, Husqvarna prepresents the best overall brand for string trimmers. They offer a wide range of trimmers for both homeowners and professionals. They also seem committed to carrying both gas and battery-powered solutions (unlike Makita ). They have solutions for cutting grass as well as forestry brush. While STIHL is known for its vast dealer network, Husqvarna remains easily accessible through its local service partners.
