Best Weedeater for 2023 – 10 Gas Models Tested. Weed eater string trimmer

Best Weedeater for 2023 – 10 Gas Models Tested

We take 10 gas-powered string trimmers and put them through our paces to determine who’s king in the Best Weedeater Shootout. Some are 4-cycle and some 2-cycle, but they’re all gas-powered. No batteries or cords here. These are the best of the beasts who tame the lawns.

Who do you think will reign as the champ? Stick around – keep reading – and you’ll find out.

Best Weedeater Shootout – Who’s In?

Here’s a quick look at which string trimmers are in this best weedeater head-to-head comparison. We have the following contenders in alphabetical order:

  • Echo – SRM-2620T
  • Honda – HHT35SLTA – 4-cycle
  • Husqvarna – 525LST
  • Makita – EM2650LH – 4-cycle
  • Ryobi – RY253SS
  • Ryobi – RY4CSS – 4-cycle
  • Shindaiwa – T262
  • STIHL – FS 91 R – 4-mix – 4-cycle running premix (oil and gas)
  • Tanaka – TCG27EBSP
  • Troy-Bilt – TB6044 XP – 4-cycle

How We Determine the Best Weedeater

In determining a ranking for the best weedeater, we want to stay as objective as possible. The less we have based on subjectivity (opinion), the better. Each string trimmer is looked at in detail, used by multiple users, multiple times. We’ve developed a points system, including multiple categories, with a possible total of 100.

We take a look at items like key features, sound-pressure level, and weight. Ergonomics also plays a big role in our calculation. Furthermore, we determine fuel efficiency, tank runtime, time-work testing, and of course, price, and warranty. We also determine a “Value” which is more of a bang-for-your-buck calculation for the best weedeater.

Without further ado, let’s see how it all shakes down in the best weedeater shootout.

Key Features of the Best Weedeaters

Cutting Swath

All string trimmers come standard with a guard to keep flying debris from hurting the operator. Well, it keeps some of the debris away. Even the best weedeater peppered your legs with grass and weed “shrapnel”. The guard also houses the cutter/blade that keeps the line trimmed a certain length. We measure the distance, in inches, from the center of the trimmer head to the cutter on the guard. Multiply this by two, and you have the cutting swath (diameter).

Our smallest swath belongs to the Makita EM2650LH, at just 16 inches. The largest is the Shindaiwa T262, at a whopping 20 inches! Will this affect cutting speed or getting work done?

Shaft Type

Do the best weedeaters have a one or two-piece shaft? Keeping this a single piece eliminates another area for wear and/or failure. All our “commercial-level” trimmers have a one-piece shaft, and the three “consumer-level” models had two-piece shafts.

The two-piece shaft allows for additional accessories to run on the same powerhead. The three 2-piece models were the Ryobi RY253SS, Ryobi RY4CSS, and the Troy-Bilt TB6044 XP.

Auto Choke

Starting up gas-powered weedeaters, edgers, and blowers can take some time. Typically, when starting the unit cold, you close the choke completely and yank the pull cord until it fires. Then, you open the choke, grab a handful of throttle and pull the cord again. Once the unit fires, you keep it throttled up until it’s warm. Even the best weedeater has to deal with winterization and cold weather startups.

With the automatic choke, you still close the choke fully, then pull until it fires. The choke then opens, pull the cord again, without your fingers on the throttle. The trimmer will fire up at a high idle, without you touching it. Once you touch the throttle, idle will return to normal. This helps warm up the machine quickly, without several extra steps.

The Husqvarna 525LST, Makita EM2650LH, and the STIHL FS 91 R are the only trimmers to include this feature.

The Best Weedeater Have Easier Serviceability

Do the trimmers include the ability to service the unit? As the trimmers are used every day, the heads eventually need to be greased, along with the shaft.

All the trimmers included a service port in the trimmer head, with the exception of the Troy-Bilt TB6044 XP.

Best Weedeater Fuel Efficiency

Fuel efficiency is important, as it’s a direct cost associated with the amount of work being done. All the units in our best weedeater comparison run on gasoline.

Four of the string trimmers are 4-cycle and require only gasoline—no remixing or oil. The Makita EM2650LH, Ryobi RY4CSS, Honda HHT35SLTA, and the Troy-Bilt TB6044 XP are all 4-cycle.The STIHL FS 91 R is also a 4-stroke, but it runs on 2-stroke fuel (premix).

How we tested: For the efficiency test, we used 8 oz. of TruFuel (either 2-stroke or 4-stroke fuel), and we ran the trimmer at Wide Open Throttle (WOT) until they ran out of fuel. Both Ryobi trimmers were the most efficient, running for more than 23 minutes on 8 oz. of fuel.

TruFuel 50:1 Mix and TruFuel 4-Cycle

To keep things equal, we used TruFuel 50:1 Mix for all our 2-cycle weedeaters, and we used TruFuel 4-Cycle for all our 4-cycle tools.

Echo Black Diamond.095 Trimmer Line

We loaded up Echo Black Diamond.095 trimmer line in all our string trimmers. This is Echo’s twisted black line that has excellent cutting qualities and works with all our gas weedeaters.

Tank Runtime

Tank Runtime is probably more of a concern than efficiency since it relates more to labor costs, which tend to be more expensive than the savings of gasoline efficiency.

How many times do I have to stop and walk my weedeater back to the truck/trailer each day?

How we tested: we used the fuel efficiency number (burning 8 oz. TruFuel @WOT) then multiplied by the number of times 8 oz. goes into the capacity of the fuel tank. e.g. If a tank is 16 oz. and the trimmer ran for 20 minutes on 8 oz. We take 20 minutes x 2 (because 8 goes into 16 two times), so tank runtime would be 40 minutes.

The STIHL FS 91 R was not the most efficient, however, it had the best Tank Runtime due to the capacity of the tank.

Best Weedeater Ergonomics

Weight

Weight is important with weedeaters because you’re literally holding all that weight in your two hands. The more weight and more time, the more fatigued you’ll be at the end of the day.

We weighed each string trimmer with 8 oz. of fuel in the tank. Also, oil was added to the 4 four-stroke models we had, to give a true representation of the weight as it would be used.

The Husqvarna 525LST is our lightest trimmer, weighing in at only 12.3 lbs. On the flip side, the heaviest contender is the Troy-Bilt TB6044 XP.

Weedeater Sound Testing – Db(A)

Using a weedeater for 10 or 15 minutes straight may not seem to bother your hearing. However, the reality proves to be much different. We measured the sound pressure level (SPL) of these best weedeaters at 50 feet. This covered the ANSI specs, however, we also tested SPL at the operator’s ear.

Hearing protection should be worn with all these models.

The Honda HHT35SLTA was our quietest trimmer, measuring just 74 Db(A) at 50-feet and 96 Db(A) at the operator’s ear. The STIHL FS 91 R was our worst sound offender at 80 and 106 Db(A).

Testing the Best Weedeater Performance

Power Trials – Thick and Thin

Why Power is important: most lawn crews use these string trimmers or weedeaters to keep the grass tamed near hardscaping or flower beds where the mower can’t reach. In addition to this, the string trimmer may be used for cutting back growth in areas that haven’t been touched in a while.

This may be fitter for the work of a brush-cutter, but the reality is the operator’s going to just pull the trigger on the string trimmer in their hand and go at it.

How well do these trimmers cut the grass and how well do they cut thick foliage?

What To Trim?

We tried to make this a little more objective by providing a material that we could cut, measuring the amount of time it took to cut. Cardboard is no match. Even the “weakest” weedeater of the bunch can cut through several inches of solid cardboard immediately.

We then tried corrugated plastic-like political signs you see all over the place during elections. This also proved no challenge. The best weedeaters cut just as quickly as the rest. Even with 5 and 10 pieces glued together…they just cut right through it. Almost immeasurable. Wood and wooden dowels were too inconsistent, and it would typically break the string before completing the task.

Cardboard tubes with ¼”-thick walls seemed to the be a great medium — for the first few seconds. However, once the trimmer would make it halfway through the cardboard tube, the string would break. Most of the time when the string broke, the line would be welded/melted together inside the head.

How About Grass and Weeds!

Finally, why not test the best weedeater with the medium that the tool was made for?! We made a 5’ x 5’ square with PVC. We used the square to lay in the grass, measuring how long it took each trimmer to cut the marked area. Each test was performed several times.

After testing in the “normal” grass, we then moved the weedeaters to thicker and taller foliage. Testing was performed on Central Florida Bahia grass. Bahia is known for it’s tough blades, wreaking havoc on lawn equipment.

Echo’s SRM-2620T cut through the thin stuff the fastest, at just 7.8 seconds. The Husqvarna 525LST was the fastest in the thick stuff, taking only 10.9 seconds to cut through.

Using the Best Weedeaters for Edging

Why is Edging important? If there’s a lot of edging to be done, lawn crews will typically grab a dedicated edger to complete the task. However, it’s not uncommon to do quick edging or to just use the string trimmer in your hand to do the work.

How well does each model handle this and does their blade guard get in the way?

Echo’s guard on the SRM-2620T deems to be the least intrusive on edging, but the Tanaka TCG27EBSP and Honda HHT35SLTA guards keep reading the line of sight more difficult.

Best Weedeater Price and Value

Why it’s important: When we tally all the results and compare that to the price of each trimmer, we understand value better. For some, it’s getting the cheapest nailer that will do the job. For others, it’s getting the best bang for your buck.

In this case, the cheapest is also the best value – Ryobi RY253SS with a 119 price tag. The worst value belongs to the Honda HHT35SLTA with a 379 price.

Warranty

Also going into the Value equation is the warranty from each weedeater manufacturer. We look at each warranty on two levels: for the consumer and commercial user. All the string trimmers include a warranty for commercial and consumer, with the exception of one.

Troy-Bilt only warranties the TB6044 XP to the consumer for 3 years and nothing for the commercial user. Ryobi offers a 90-day warranty for commercial use and 3-years for consumers.

The Tanaka TCG27EBSP weedeater is warranted for 2 years for commercial use and 7 years for the consumer.

Final Conclusion

Well, we let the numbers speak for themselves. Quite frankly, this fight was not all about power, per se. Reason being is that all the manufacturers are putting very good power to the ground. It’s really amazing what these small displacement powerplants can output. With all of them able to get the job done, it came down to ergonomics, feature set, and value. A pound or more extra weight can really get to you after hours of work.

best, weedeater, 2023, models, tested, weed

We really didn’t add or subtract based on 2-cycle or 4-cycle. 2-cycle trimmers require oil to be mixed in the gas, however, 4-cycles need crankcase oil and oil changes – even valves adjusted after some time. We consider these a wash in terms of benefit. Now, in terms of preference, that’s up to you.

We would have like to have seen RedMax and Efco in the fight as well, but they declined to enter the best weedeater shootout. Let us know how we did and if you would like to see any other trimmers in the mix.

String Trimmer Maintenance Safety

String trimmers, also known as “weed wackers,” “weed eaters,” “weed whips” and a host of other names, are essential lawn tools and should be as big a part of a lawn care arsenal as a lawnmower. While the lawnmower usually does most of the heavy lifting, the string trimmer cuts down all the grass that the mower can’t reach along hardscaping edges, around trees and other objects. This is a handy guide on how to maintain your string trimmer and use it safely to make your yard a manicured marvel.

Maintain a String Trimmer (Weed Wacker)

Properly maintaining your string trimmer is essential. While both gas-powered and electric models require some effort to keep them in prime running condition, the two types do require different amounts of maintenance. Because of its engine, a gas-powered model requires more upkeep. Corded electric models and models with rechargeable lithium-ion batteries are convenient because they don’t require fuel, oil or spark plugs. Depending on your particular lawn care needs, however, electric models may not supply the amount of power required to cut through heavier growth. So keep that in mind and weigh your specific needs before purchasing.

Step 1: Clean and Inspect the Trimmer

Clean the string trimmer to keep it performing well. Dust, grime and caked-on grass clippings build up on the debris shield and trimmer head and can lead to inefficiency and possible malfunction if not cleaned. Wipe the trimmer parts down with a rag after use and before storing it. Do a deeper cleaning with a stiff brush and a damp cloth periodically. Use cotton swabs, lightly dampened with machine oil to clean exhausts and intakes and other hard-to-clean areas.

Helpful Tip

Use an air compressor or a can of compressed air to blow air into the trimmer engine vents and crevices to remove dirt and dust from inside.

Remember to inspect your string trimmer for any signs of wear or damage when you’re cleaning it.

Safety Alert!

Before cleaning or maintaining your string trimmer—particularly when handling the business end—always remove the spark plug from a gasoline-powered unit. Unplug the power cord or detach the battery from an electric unit.

Helpful Tips

Store your trimmer and accessories somewhere where they will be protected from dust and moisture, preferably in a garage or tool shed. This not only keeps them protected, it also keeps them organized so you can easily find the tool you need when you need it.

Remember to keep the instruction manual. Not only is it a great guide and resource on how to properly and safely use your string trimmer, the manual also has valuable information on how to care for it, find replacement parts and other important pieces of information.

Step 2: Replace Trimmer Line

No matter if your trimmer model is gas-powered or electric, both require replacement of the trimmer line periodically. The type of head on your trimmer does determine how you replace the line though. You will most likely have a single or dual-line head. This means that there will be one or two protruding pieces of line for cutting. Follow the instructions from your trimmer’s manufacturer on how to replace the line.

Helpful Tips

Keep surplus trimmer line around so that you don’t run out and have to stop working to go buy more.

When replacing the trimmer line, take this time to clean the trimmer head. Use a damp rag to remove caked on grass and debris.

Step 3: Check/Change Oil and Fuel

If you’re using a gas-powered string trimmer, you need to maintain its engine by considering its fuel/oil requirements. Gas-powered string trimmers use oil and gasoline to function, with some using a fuel/oil mixture, depending on the type of engine. Four-cycle engines have separate gas and oil reservoirs, while 2-cycle engines operate on a mixture of gasoline and 2-cycle engine oil.

Consult the manufacturer’s instructions on the proper fuel/oil ratio (typically 50:1 or 40:1) if you own a trimmer with a 2-cycle engine. Use a funnel to pour the fuel and 2-cycle oil into a small gas can to mix them together at the correct ratio. Fill the trimmer’s fuel reservoir when needed.

When using a 4-cycle trimmer, check fuel and oil levels before each use. Remove the spark plug before doing any maintenance. This will ensure the trimmer is completely deactivated. Your particular trimmer model will determine how you can check its oil level. Some models will have an oil level window, or a dipstick; in lieu of either of those, you can simply open the oil reservoir and peer inside to check the oil level. Shine a flashlight on the opening if you need help seeing inside. Fill the reservoir with the manufacturer-recommended type and amount of oil when needed. Use a funnel for spill-free filling.

As with a motor vehicle, the oil will turn dark when it‘s time to change it. Remove the reservoir plug and position the trimmer so that the old oil will drain into an oil pan or another container. Once all of the oil has drained, use a rag to clean up anything that spilled and then fill the reservoir with the appropriate oil type by pouring the oil through a funnel into the oil reservoir. Check the oil level again to ensure that the proper amount has been added and then close the reservoir by inserting its plug.

Step 4: Check/Replace Air Filter

Gas-powered models also require that you check the engine air filter. Read the manufacturer’s instructions to determine where your air filter is located and how to access it. Check to see if the filter is covered with dust and debris. Some filters are washable and reusable. Check your owner’s manual for instructions on how to clean the filter. If the filter is unsalvageable or damaged, replace it.

Step 5: Store Trimmer Appropriately

Where and how you store your string trimmer when not in use is essential to keeping it in prime working order. Store your trimmer in a well-ventilated tool shed or garage, out of the elements. Do not store gas or gas/oil mixtures for the trimmer inside your home or basement. Fumes can build up and create a dangerous situation. Be sure that the trimmer and other tools are not accessible by children.

Wait for the engine to cool before putting the trimmer away. When storing your trimmer at the end of the season, remove all dirt, grease and debris from the trimmer using a stiff-bristle brush. Tighten all screws and nuts. Drain the fuel tank, remove the spark plug and add a small amount of oil into the cylinder. Pull the starting cord a couple of times to distribute the oil. Reinstall the spark plug, but don’t connect the ignition cable.

String Trimmer Safety

In addition to maintaining your trimmer, you also need to know how to operate it safely. Follow these tips on how to use your string trimmer safely and efficiently to keep your landscape neat and trim.

Use Proper Technique

Using a string trimmer properly is the first step in keeping yourself and others safe during operation. Keep an eye out for any people or pets around where you’re working. String trimmer line spins at high velocity and can pick up rocks and other debris and fling them at high speed. If someone approaches your vicinity, stop cutting until they have passed. Keep an approximate 50 feet between yourself and any bystanders. Do not remove debris shields and other safety features built into your trimmer. Always cut away from yourself.

When refilling fuel or oil, or when starting a gas-powered trimmer, place the machine on the ground. To start a gas-powered trimmer, pump the primer bulb to feed gas to the engine, turn on the choke and then pull the starter cord. Once the unit is operating, lift it, adjust the choke and let it run for about a minute to warm up.

best, weedeater, 2023, models, tested, weed

Keep the engine of the trimmer at waist level with the head of the trimmer parallel to the ground. Move the trimmer from side to side along the area to be cut. Always ease into the cut, so that you don’t cut too much, or damage something you’re not trying to cut. Keep in mind that string trimmers are meant to cut grass and similar growth; don’t use a string trimmer to cut thicker growth. It probably won’t work well—you will waste trimmer line and put strain on the trimmer engine. To get the best results, keep an eye on your trimmer line to be sure it is protruding at an effective length for cutting. Depending on your trimmer model, the line may spool out automatically as it is cuts, then wears and breaks off. If your trimmer head does not have an automatic line feed, you may need to pull it out by hand to the right length. Be sure you have turned off the trimmer beforehand.

Wear Safety Equipment

Dress properly and wear safety equipment to protect yourself from potential injury from flying debris. Wear long pants, long sleeves and work gloves. Wear safety glasses to protect your eyes. Gas-powered models can be very loud when operating and cutting. Wear earplugs to protect your ears. Great job! Now you know how to maintain and safely use your string trimmer.

BRUSH Trimmer Head !? REVIEW AND TEST #3

How We Tested the Best Gas String Trimmers

Shopping for a string trimmer reveals that statistics can only forward the search so far. Regardless of the engine size, machine weight, shaft length, and other measurables, much of the tool’s effectiveness depends on the operator’s physical build and personal preferences, along with the type of trimming to be done. To learn more about the trimmers on our list, we field-tested them in a variety of settings.

We spent 2 days testing the gas string trimmers in this article on regular lawn trimming, close-quarters trimming among shrubs and perennials in landscape beds, and mowing an overgrown field. After unboxing and assembling each trimmer, we filled the fuel tank and got started.

Our initial notes included measurable and easily observable features, such as each machine’s physical size and weight, whether it had a straight or curved shaft, and whether or not it could be used with other tool attachments. The first operational tests were simply to start each machine and note the number of pulls required to get started.

We then used each machine for 30 minutes of field mowing and 15 minutes each of lawn trimming and landscape bed trimming. In each setting, we noted perceived cutting power, responsiveness to triggering, responsiveness to bumping out new trimmer line, operator comfort, and whether or not refueling was necessary to complete the project. Finally, we reloaded each cutting head with trimmer line and noted the difficulty.

We recorded our field notes and used a scoring rubric to organize the trimmers with award titles for this guide.

Our Top Picks

The lineup of gas string trimmers was chosen based on the individual safety features, attachments, and engine type as well as product quality and the other important factors mentioned above. The following products were tested in situations DIYers are likely to encounter on their property and proved to be among the best gas string trimmers for keeping the yard and garden neatly trimmed.

Echo SRM-225i

Our top pick proves the adage, “You get what you pay for.” The Echo SRM-225i string trimmer costs a little more than some of the competitors we tested, but it delivered the best combination of easy start-up, overall working comfort, and grass trimming power at a reasonable price.

Powered by a lightweight, high-output 21.2cc two-cycle engine, this trimmer cuts with satisfyingly aggressive results in dense grass and coarse weeds, and uses less fuel than competitors with larger engines. It makes a 17-inch cutting swath and features a speed-feed head that reduces the time it takes to reload the trimmer line by half. The 59-inch straight shaft offers excellent reach beneath shrubs and into tight corners. The weight-balanced design, rubber overmold grip on the handles, and ergonomic throttle trigger reduce operator fatigue for extended use.

No assembly was required to get started with the Echo straight-shaft string trimmer. The position of the fuel tank made it easiest to fill with the motor elevated. Using a 1-gallon fuel can, we held the trimmer in one hand while pouring with the other. Following the start-up instructions printed on the machine, it started on the third pull of the recoil cord.

We were pleasantly surprised by the way the smaller-than-average motor powered this trimmer through coarse vegetation and even small, woody stems. Performance exceeded the 25cc trimmers we tested and rivaled the 27cc models. The weight of the motor was well balanced by the long, straight shaft, so maneuvering was very easy and comfortable, even after an hour of use. The rubber grips on the handles deadened any vibration so that we didn’t experience the hand fatigue or numbness that sometimes comes with hours of weed wacking. Though not the most powerful brush-cutting string trimmer we tested, this Echo model makes the best case for general trimming and frequent, larger cleanup projects.

  • I-75 ignition system reduces start-up effort
  • Speed-feed head makes adding trimmer line easy
  • Spool can’t be wound in the wrong direction
  • Anti-vibration design; cushioned front and rear grips
  • Compatible with heavy-duty.095 trimmer line

Husqvarna 330LK Gas String Trimmer

The Husqvarna 330LK Gas String Trimmer offers heavy-duty capability for trimming, edging, and other yard-care tasks. It features an attachment-compatible shaft that comes with the high-capacity Rapid Replace trimmer attachment and is compatible with lawn-edger, hedge-shear, and pole-chainsaw attachments. Spring-assisted recoil starting, a powerful 27.9cc two-cycle engine, and customizable trimming swath make this multitasking trimmer one of the top performers in our tests.

While it offered similar benefits of reach and power as the other straight-shaft trimmers, the Husqvarna attachment-capable trimmer stood out in our tests in terms of controls and overall feel. The auto-return on-off switch defaulted to the “on” position, and the pull-out choke lever made it obvious which position was for cold starting versus running—two points of confusion on many trimmers.

The spring-assisted recoil starter took some getting used to. There was a catch point mid pull, before which we could feel resistance slightly intensifying, but afterwards the power-assist mechanism released. Overall starting was easy (never more than three pulls), and the motor ran relatively quietly (although we wore over-the-ear hearing protection for the tests).

Powered by the largest motor in our test group, the trimmer did a fantastic job cleanly snipping the tops of wayward grass blades and hogging through heavy overgrown weeds. The vibration-dampening system seemed to reduce hand fatigue, but after an hour of operation, the machine’s weight was more tiring overall than the other trimmers. Adding a harness system could help for bigger jobs. This model seemed like a really good fit for those who want to get the most production from a single machine, with plenty of power for a wide range of tasks.

  • 27.9cc engine delivers more power for tough cutting conditions
  • Spring-loaded Smart start and air purge for easier cold starting
  • 20-inch-wide cutting swath reduces trimming time
  • Compatible with Husqvarna power-head attachments

Ryobi 2-Cycle Straight Shaft String Trimmer

For those just starting to build their outdoor power-tool collection, a reliable and budget-friendly choice makes sense. The Ryobi straight-shaft string trimmer delivers plenty of power to knock down grass and weeds, and it’s attachment capable for punching out more yard chores beyond just trimming.

This trimmer features a 25cc two-cycle engine and includes the “reel-easy” Rapid-loading trimmer head. The shaft is compatible with Ryobi expand-it attachments, including the lawn edger, cultivator, pole chainsaw, leaf blower, and hedge shear, sold separately.

The Ryobi string trimmer was ready to go within 5 minutes. Out-of-the-box assembly required attaching the debris guard above the cutting head and inserting the attachment into the power-head shaft. When we added fuel, we noted that the tank’s opening was quite small, so we had to pour very carefully (or use a funnel) to avoid spills. Also, the opening is oriented horizontally, which could pose a leak problem with age but was not a problem for us.

For the low price, we were impressed with this trimmer’s performance. It tore through weeds and grass with a similar effect as the more expensive models. But this machine was significantly louder and vibrated more than the pricier competition. We also noted that the Ryobi was one of two machines in our tests that did not run a full hour on a single tank of fuel—we had to refuel at about 55 minutes. But for anyone on a budget, this weed wacker makes quick work of trimming jobs and may save money and storage space when other attachments are added.

  • Ample power for trimming and edging; suitable for both thick and thin plant and grass varieties
  • Works with hedge-shears, lawn-edger, or pole-chainsaw attachments
  • Easy to maneuver into hard-to-reach areas

STIHL FS 70 R Grass Trimmer

Even at a premium price point, landscape pros and commercial property managers choose STIHL string trimmers and brush cutters for their combination of power, durability, and operator comfort. The STIHL FS 70 R commercial-grade straight-shaft string trimmer features a fuel-efficient 27.2cc two-cycle engine to go along with its rugged but lightweight polymer housing. To protect the environment and the health of workers, this trimmer earns the STIHL “Caring For Nature” rating as a low-emissions trimmer that operates cleaner than Environmental Protection Agency requirements.

Among the trimmers we tested, the STIHL models were more expensive and a little harder to get, but worth it. STIHL only sells through its network of authorized full-line servicing dealers, so online ordering is limited and home delivery is generally not available. But the process eliminates out-of-the-box start-up problems because a certified technician assembles, tests, and adjusts the machine at the dealership prior to customer pickup.

Our first note on this trimmer was that the fuel-fill opening is conveniently wide and extremely easy to access, even while the machine is resting flat on the ground. For our tests, the FS 70 R started on the first pull. It ran noticeably smoother than any of the other machines, both at idle speed and at full throttle, with delay-free acceleration when triggered. The trimmer cut cleanly through tall grass and densely overgrown weeds without getting wrapped up or bogged down in debris. As for fuel efficiency, even with the modest 11.5-ounce fuel tank, we were able to trim for a full hour without stopping to refill. The AutoCut trimmer head was fast and easy to respool without disassembly.

Another point for consideration was the overall operating comfort. Not only was the FS 70 R the lightest straight-shaft trimmer we tested, but it also came with a shoulder strap that transferred all of the machine’s weight away from the hands. As a total package, this would be our machine of choice for all-day trimming on large properties.

  • Very lightweight design; easy to maneuver design
  • Carry strap for extended-use comfort included
  • Protected choke lever reduces risk of damage in transport
  • Easy-access air filter for quick clean out or replacement
  • High-power engine and excellent fuel economy increase work productivity

Husqvarna 130C Curved Shaft String Trimmer

This Husqvarna gas trimmer has a curved-shaft design that is intended to make it easier to cut parallel to the ground. The trimmer features a bump feeding system, enabling the user to extend the string from the dual-line head by tapping the trimmer head against the ground.

The two-cycle gas string trimmer is a good option for homes with small to medium yards, as it weighs just 11.8 pounds and has a 17-inch cutting width. It protects the user with a debris guard cleverly designed with a narrow extension from the shaft widening to a broad, protective shield; this combination makes it easier to see where the trimmer is cutting without sacrificing safety. The trimmer also has a trigger safety switch, which must be activated before the variable speed trigger will respond, helping prevent accidental start-ups.

The Husqvarna curved-shaft trimmer weighed less than most straight trimmers but a little more than the other curved shaft trimmers in our tests. It arrived ready to work, with no assembly required. After filling the fuel tank, it started on the third pull and delivered powerful and surprisingly quiet performance.

The molded fuel cap was easy to grip, and the tank mouth was wide enough to fill easily. We found it convenient to rest the engine on an elevated surface for refueling. The spring-assisted recoil starter made starting easy—typically on the second pull in our tests. The trimmer easily mowed down all of the coarse weeds and thick grass in its way. We loved the responsiveness of the bump cutting head, which seemed to feed more easily than most of the other trimmers we tested. For curved-shaft enthusiasts with small to midsize yards, this could be a great choice.

  • Surprisingly quiet operation for such a powerful engine
  • Plenty of power to whack coarse weeds and thick grass
  • Curved shaft comfortable for users under 6 feet tall

STIHL FS 40 C-E Gas String Trimmer

Curved-shaft trimmers are touted for the weight reduction that comes from a shortened shaft—but they often place more weight on the user’s rear hand, which can increase operator fatigue. Weighing less than 10 pounds, the STIHL FS 40 C-E Gas String Trimmer pairs the lightest design in our roundup with a shoulder strap that transfers the load to the operator’s core. The result is a major upgrade in extended-use comfort for curved-shaft trimmer users.

This machine also excels in trimming performance. The 27.2cc engine runs clean and smooth, delivering commercial-grade cutting power, excellent fuel economy, and low exhaust emissions. It has earned STIHL’s “Caring For Nature” seal for exhaust emissions that outperform EPA standards.

We were pleasantly surprised by the bargain price on the STIHL curved shaft trimmer—just a few dollars more than our Best Bang for the Buck pick. It was worth every penny. As with the other STIHL trimmer on our list, this model was assembled and tested at the dealership before we picked it up. Both machines are built with the same engine type.

The FS 40 C-E started on the first pull and tore through all of the grass and weeds in its way without hesitation. The engine ran and accelerated very smoothly throughout testing, with a crisp response to triggering. We cannot overstate the value that a shoulder strap adds to this curved-shaft design. The other curved trimmers we tested left us with heavy right arms from carrying the weight of the motor after an hour of trimming, but this STIHL did not. In fact, the shoulder strap increased overall maneuverability by providing a pivot at the attachment point. Arm and shoulder muscles were used only to guide the direction of the trimmer. This makes an excellent pick for any curved-shaft trimmer user, especially those faced with hours-long jobs.

  • Budget-friendly price for industry-leading performance
  • Very light weight, plus shoulder strap to further decrease load
  • Easily cuts through dense grass and coarse weeds
  • Very low exhaust emissions for a reduced environmental impact

Craftsman 25cc 2-Cycle Straight Shaft Gas Trimmer

At 13 pounds, this gas string trimmer is considered lightweight, but it weighs a bit more than most of the competition we tested. It features a dual-line head that cuts a 17-inch swath, making this trimmer a good choice for yards up to 1 acre or for any locations where landscaping and lawn ornaments demand precision trimming.

The trimmer comes with a debris guard and has a multiposition handle that can be adjusted to the user’s preferred position for better control and comfort. It also features a bump feeding system so the available line can be extended by simply tapping the head on the ground. This trimmer has a straight shaft, and the head can be removed to make string loading easier. It works with other Craftsman trimmer attachments, which are not included.

In our tests, the Craftsman trimmer performed similarly to the Ryobi. Both featured no-frills design and powerful cutting action, and both were priced near the low point among our test group. Installing the debris guard and loop handle took about 5 minutes. We added fuel and were ready to start. This was the only trimmer we flooded by overpriming while attempting to start the first time. After waiting a few minutes, it started on the fourth pull.

The 25cc motor provided ample power to cut through thick grass and weeds. The cutting head was easy to reload with a new trimmer line. The machine ran a bit louder than the other trimmers we tested, and we felt more vibration in the handles. Still, because of its modest price, and especially because of its ability to power other tool attachments, this Craftsman string trimmer has a lot to offer budget-conscious homeowners.

  • Lowest price point of all trimmers we tested
  • Ample power for grass trimming and weed wacking
  • Attachment-capable shaft compatible with numerous yard-care tools
  • Easy winding bump head for fast trimmer-line reloads

Echo GT-225 Curved Shaft String Trimmer

The Echo GT-225 string trimmer makes yard work easier thanks to its lightweight curved-shaft design and professional grade 21.2cc two-cycle engine. Weighing just over 10 pounds, this trimmer is easy to carry and highly maneuverable—an ideal build for smaller yards. The two-line Rapid-loader cutting head trims a 16-inch swath and uses precut trimmer line for easy line changes.

The GT-225 curved-shaft trimmer arrived ready to work and no assembly was required. After adding fuel, which worked best with the engine resting on an elevated surface, it was ready to go. We noted that this Echo trimmer is powered by the same engine type as our Best Overall pick. It started easily on the second pull, accelerated smoothly, and delivered cutting power seemingly beyond its 21.2cc engine displacement.

As with the Husqvarna curved-shaft trimmer, the shorter shaft left a greater proportion of the machine’s weight in the operator’s rear hand. But the lighter overall weight made it a bit less tiring. One aspect of this trimmer that really stood out was the unique cutting-head design. It uses fixed pieces of trimmer line instead of feeding from a reserve spool. It cuts well, but when the trimmer line wears down, the operator must stop and reload. This design is most practical for small yards where multiple reloads will not be required.

  • Smooth-running, surprisingly powerful 21.2cc 2-cycle engine
  • Easy to maneuver in small landscapes
  • Durable and fuel efficient
  • Simple cutting-head design makes it easy to reload

What to Consider When Choosing the Best Gas String Trimmer

A string trimmer is a powerful tool equipped with weed-eater string to cut through overgrown grass and weeds quickly. For help deciding on the best gas string trimmer for your home’s landscaping, consider the following criteria: engine type, fuel efficiency and runtime, cutting width, feeding and loading, speed, ease of use, attachments, and safety features.

Engine Type

Gas string trimmers fall into two categories based on the type of engine they use: two-cycle or four-cycle. This seemingly simple difference creates significant gaps between efficiency, cost, maintenance, and power.

  • Two-cycle engines are lightweight, allowing the user to move more freely while working with the trimmer. Two-cycle engines use a fuel-and-oil blend, which reduces average maintenance to changing the weed-eater string and emptying the fuel tank before storing the trimmer for the off-season. Though lower maintenance, these trimmers have less power output than those with a four-cycle engine.
  • Four-cycle engines are generally considered more efficient than two-cycle engines. The efficiency comes at the cost of size and weight, so users should expect a heavier tool when they pick up a four-cycle engine trimmer. These tools also are more powerful than products with two-cycle engines, making them a good choice for yards that are more than an acre. However, products with four-cycle engines typically cost more and require regular oil changes to keep them working properly.

The size of the engine is another important factor. This is measured in cubic centimeters (cc). As an engine increases in size, as indicated by the cc, the power output of the engine increases. This is because a larger engine is generally capable of displacing more air and fuel at one time. When displacement is low, power output is also low. So if high power is the goal, look for a product with an engine larger than 40cc.

Fuel Efficiency and Runtime

Fuel efficiency can be difficult to gauge, as there are a number of different factors that can influence it, including fuel mixture, ambient temperature, operating speed, and even the type of grass or weeds being cut. However, a gas string trimmer with a four-cycle engine will usually be more efficient than a trimmer with a two-cycle engine.

Runtime is a bit easier to measure because manufacturers typically provide the fuel-tank size and the maximum runtime on a single tank of fuel. These runtime numbers are based on tests performed in ideal, controlled environments, so factors like high- and low-temperature extremes or very dense, wet foliage can reduce the actual runtime. These situations decrease the fuel efficiency of the trimmer, causing it to use more fuel in a shorter period of time.

Cutting Width

The cutting width of a gas string trimmer refers to the total width the rotating string can reach when the trimmer is in use. Standard gas string trimmers will have a cutting width of about 16 to 18 inches. However, there are compact models that may be as small as 12 inches wide and commercial gas string trimmers that exceed 20 inches wide, so it’s important to know what size is necessary for the lawn, yard, and garden.

Yards that exceed 1 acre and have very few small obstacles may benefit from a gas string trimmer with a cutting width of 18 inches or more, while yards that are smaller than 1 acre are fine with gas trimmers that have a smaller cutting width. Users with many obstacles in their yard may prefer a smaller cutting width so they can have more precise control. For cutting through deep, dense weeds and overgrown grass, it’s helpful if the cutting width is big and the engine is powerful.

Variable Speed Control

The speed of a gas string trimmer is controlled by a variable speed trigger that can either be placed on the shaft of the tool or on one of the handles (if the model has a split-handle design). Trigger placement on the right handle may cause problems for left-handed users. When the trigger is on the shaft of the trimmer, it’s relatively easy to use either hand to control the speed while the other hand controls the movement of the trimmer head.

Variable speed control allows the user to reduce the speed for light trimming or increase the speed to cut through dense brush and weeds more rapidly. The ability to dial down the speed for precision control is great while trimming around lawn ornaments, garden beds, and along fencing to reduce the potential damage that can be caused by less controllable trimmers.

Loading and Feeding

Loading and feeding the line tend to be the most challenging parts of using a gas string trimmer. Loading refers to installing the cutting string, which can be difficult, especially when dealing with a dual-line head that has two weed-eater strings. To help make this task easier, shoppers will want to consider products with a detachable head so they aren’t fighting with the entire trimmer while trying to change the line.

Feeding the line refers to pulling more line out of the trimmer head. There are now many products that offer innovative line-feeding methods that eliminate the need to start and stop while using the trimmer to deal with a standard fixed line. These include bump feeding and auto feeding.

  • Fixed-line gas string trimmers are attached tightly to the head, meaning the user needs to loosen the head and manually pull the line out when more is needed.
  • Bump feeders are designed to push out more string when the head is bumped on the ground or on another hard object so the user needn’t stop to extend the string.
  • Auto feeders have a prewound head that automatically feeds string using centrifugal force, so the string is constantly self-correcting to the ideal length.

Ease of Use

Using a gas string trimmer can be tiring, but several factors can help make the work easier. These include the angle of the shaft, the weight of the string trimmer, the balance of the trimmer, and the trimmer head.

  • The shaft of the trimmer can either be completely straight or curved. Curved shafts are great for getting a flat angle cut over a broad area without having to bend and twist to change the cut of the trimmer. Straight shafts are better for detailed trimming between and around lawn ornaments.
  • The weight of a trimmer can tire the user, especially if working in a very large yard or dealing with many different precision cuts. Additional time spent trimming can lead to aching arms and shoulders, so a lighter trimmer of 10 to 12 pounds may be a better option. If the power of a heavier trimmer is needed, then work breaks may be necessary to avoid injury.
  • The balance of the gas string trimmer is dependent on how the weight of the engine, focused at the rear of the tool, compares to the weight of the rest of the trimmer, which is dispersed along the entire length of the shaft down to the head. Unfortunately, balance is difficult to determine without actually holding the tool, so be sure to read product information and hands-on reviews, such as the ones that appear here, to get a good idea of how the trimmer handles.
  • The trimmer head can come with a variety of attachments detailed below. It can also have a versatile tilting feature that allows the head to be angled up or down for more precise cutting in tight spots.

Attachments

When using a gas string trimmer to clean up the yard and garden, it’s possible to encounter sticks, leaves, and debris; the trimmer is useless to deal with these unless it comes with an edging tool, saw, blower, or brush attachment.

  • Edging tools are useful for creating a defined edge between the garden and the lawn or the lawn and the sidewalk or driveway. They have a more powerful cutting blade that makes quick work of overgrown grass, which saves the time and effort of using a shovel to edge the lawn.
  • Saw attachments are a great choice for cutting through sticks and brush that have fallen during the fall and winter seasons. While it shouldn’t be used for cutting through logs or planks of wood, the saw moves easily through small branches and twigs.
  • Blowers are a separate tool, but sometimes they are packaged as a kit with a trimmer. They help quickly clean up a mess made by trimming, edging, and cutting.
  • Brush attachments can help clean up a messy sidewalk or driveway, pushing the yard debris into a pile or just brushing stray grass and dirt back onto the lawn.

Safety Features

Before picking up a gas string trimmer, it’s important to remember that this device is designed for cutting through layers of the tough cellulose fiber of plants while hitting walls, rocks, metal, and wood at an impressive speed. It is a machine that should always be handled with proper precautions. With this in mind, look for gas string trimmers that have safety features like a debris guard, a trigger switch, and a padded grip.

  • Debris guards are included with almost every gas string trimmer because they are essential to protecting the user. Even with a guard, some flying grass can escape, which is why users must wear safety glasses, long pants, and closed-toe shoes while working.
  • Trigger switches are designed to prevent the trimmer from being accidentally turned on. The trigger switch must be held down before the trigger will activate the trimmer.
  • Padded grips on the shaft and handle of the gas string trimmer will help reduce hand fatigue and muscle strain that can be caused by excessive vibration. The padding also makes the tool easier to hold and helps prevent it from slipping out of the user’s hand while trimming.

FAQs

If you’re still unsure about some of the details surrounding gas string trimmers, read the following answers to some of the most commonly asked questions about how to use these trimmers as well as how to store and maintain these machines for years of use.

Q. What size gas string trimmer do I need?

When trying to decide on the right size trimmer, consider the size of the yard, the number of obstacles in the yard, and the type of obstacles. Generally, larger yards without many obstacles will be easier with larger gas string trimmers. Yards with gardens, low-hanging plant leaves, lawn ornaments, and fences are better handled with a smaller trimmer.

Q. How do you store gas string trimmer?

To keep it safe from hot- and cold-temperature extremes, precipitation, and debris, store a gas string trimmer off of the floor inside a workshop or garage. This can be done by hanging the gas string trimmer on the wall using two or more hanging hooks. Make sure to empty the gas from the trimmer before storing for the off-season.

Q. How long do gas string trimmers last?

Gas string trimmers can last about 5 to 10 years, with some difference in longevity depending on how the trimmer is stored and if it is maintained properly.

Weed Eater String Sizes Explained

When it comes to string trimmer lines, size is all about thickness of the string. Think back to geometry in high school and how things were measured using diameter, or the distance from one end to another. The true width of the weed eater string.

Us Americans use the correct way of measuring things and it is in inches. There are some who will measure weed eater string in millimeters and they are not to be trusted.

But here are the common weed eater string sizes and what they mean.

Let me explain what I mean further here:

.060 inch Weed Eater String

.060 inch weed eater string is great for smaller weed eaters. If you have a Black and Decker string trimmer or WORX weed eater that is relatively small, you can get away with using this string.

This is the smallest string trimmer line on the market and is also one of the most popular for normal homeowners. In my opinion, homeowners leave a lot on the table by just buying the “stock” weed eater string for their Ryobi, WORX or Black and Decker weed eaters.

.060 is really light and pretty cheap, but sacrifices durability and cutting power. on that later.

.080 inch Weed Eater String Size

.080 inch weed eater string is a great alternative to.060.

It has more thickness than.060 weed eater string but isn’t so thick that it slows you down. It adds more durability to each cut and is still extremely easy to load into basically ANY weed eater, even ones that normally take.060.

The added benefit of the.080 inch weed eater string is that there is more room to create patterns or different shapes in the string that allow for added cutting surfaces that absolutely melts grass.

Pros of.080 inch weed eater string:

.095 inch Weed Eater String Size

If I were to apply the scientific “Goldilocks” method, I would say that.095 inch string trimmer is just right. Here’s why.

Once you start using a.095 inch weed eater string, there’s a noticeable difference. I put it in my Ryobi Expand-It (cheap) weed eater and it freaking rocked.

For starters, the.095 inch weed eater string is heavier. In some tests we ran with an EGO string trimmer, it absolutely dominated the grass. It was truly the Mike Tyson of weed eater string.

This weed eater string is when you’ll start to notice more tension when winding it. This makes it a little tougher to load, but adds a ridiculous amount of cutting power.

We think.095 weed eater string is the best thickness of all the weed eater string we’ve tested – which is a LOT.

Most weed eaters that take.095 inch weed eater string make it so that you can’t tell. For example if you are using an Echo SRM 225 or comparable battery-powered weed eaters, this thing will load like a breeze.

Cons of.095 inch trimmer line

.0105 inch and above Weed Eater String

.0105 inch and above string trimmer is really going to be commercial applications. Think dudes that are doing commercial landscaping jobs around schools, libraries and office buildings. They’re also used in walk behind string trimmers that have great use as pseudo-lawn mowers for dense brush or wild land.

This stuff is not going to be great for the average homeowner or even most residential landscapers and is far less common. But it still has its place as an absolute beast in all types of trimming for big, professional jobs.

Weed Eater String Colors

Many people think weed eater string colors correlate to thickness or patterns or something else. That’s not true – there is no correlation between color and thickness across all the different providers of string trimmer line.

The truth of colors when it comes to string trimmer line is simply preference. But there are important things to note with color.

Most notably, the color of the weed eater string is there to help you visualize the string better. There are dozens of different colored strings out there, but what you’re really looking for is how the string looks when it’s spinning a few thousand rotations per minute.

We have tested just about every color and our favorite was surprisingly bright green, followed by orange.

Bright green and orange gave the best contrast to the grass when cutting it. Visibility is really important when using a weed eater, especially around delicate surfaces like a shed, a deck, or even prized flowers and plants. You can accidentally seriously damage many things around your yard if you don’t know exactly where you are cutting.

We were least impressed by the red, black, gray, and clear string trimmer lines. They simply disappeared or were hard to see when up and spinning.

Weed Eater String Shapes

You may notice if you’ve spent any time shopping for string trimmer line that it comes in a bunch of different shapes. This isn’t just a marketing gimmick (okay it seems like some of it is), but has some serious utility. Let me break down what we have seen and tested over the past few weeks.

The different shapes

These things look like you walked into the space bar in Star Wars. Creatures from every end of the earth. Some of the most common weed eater string shapes are:

We learned a lot when we tested all of these suckers. I’m going to group these into round, pointed, and braided / twisted.

Round weed eater string

Round weed eater string is probably the most common. It is the “stock” weed eater string because it is super easy to manufacture, isn’t complex, and is easy to wind and fit into every string trimmer.

We expected this one to be the worst in our tests for all the above reasons. It surprised us.

It still wasn’t the best, but it was much more durable than we expected. You would think it would be the easiest to break because it isn’t as “hardcore” as the pointed and patterned ones, but it was pretty structurally sound.

Round weed eater string had average performance when it came to cutting performance. Nothing special, but not poor by any stretch.

Pointed weed eater string

For weed eater string that had several sides, like a square or hexagon, we actually found the string to be more brittle. We did not expect this. It definitely has more razor-like qualities that help cut grass more, but it also exposes much more structural breakdown opportunities when compared to round weed eater string.

There was one in particular that was star-shaped that we tried and it truly seemed to break down every 10 seconds or so.

The best weed eater string shape we found was a triangular shape. It had fewer points, but still had the razor-like quality that shredded grass. We found it to have the most structural integrity while providing the best cutting power.

Braided and twisted weed eater string

The cool things about braided and twisted weed eater string is that it has a meaningful impact on the sound of the string trimmer. It is much quieter spinning, which is great. But in reality, the spinning string is not really the loudest part of most weed eaters – it’s the motor.

So while the braided and twisted lines are quieter, they still hardly make a dent on the overall noise level of the weed eater.

Spiral and braided string trimmer also have more durability than non-twisted pointed weed eater string. Obviously they don’t make a twisted, round weed eater string (it would just be round) so it really just applies to patterned ones.

Overall these are more durable but only apply to less durable string trimmer lines with patterns. So they are good benefits in the end but also come at an extra cost. I’ve also found the twisted ones have more built-in torque, making them harder to load into your weed eater.

How to replace weed eater string

We’ve included a super short YouTube short we made below:

Common questions about weed eater string we get

Yep, over the years we have compiled dozens of questions about weed eater string that we get over and over. Let’s get started:

Can I use a thicker trimmer line?

To a point, yes. For most residential weed eaters, you can use up to.095 before things start to get hairy. Many gas trimmers can go higher, up to.105 or.110 but not much higher than that.

How do I know what size weed eater string to use?

Conventional wisdom says that for most residential weed eaters.095 or.080 are the most common sizes that fit your weed eater and maximize performance.

What size weed eater string is best for STIHL weed eaters?

We have had luck using a.095 weed eater string for STIHL’s weed eater lineup. It fits their gas powered weed eaters like the STIHL FS 56 RC and should fit most of their battery-powered ones as well.

What size weed eater string is best for Echo weed eaters?

Echo weed eaters like the SRM 225 can handle.095 or.105 thickness to get the job done.

What size weed eater string is best for Ryobi weed eaters?

There’s a huge variety of weed eaters offered by Ryobi, but my Ryobi weed eater absolutely crushes with.095 weed eater string. It came with.060 but I upgraded and it took it from a dinky tool to a freaking machine.

What’s the best weed eater string for Husqvarna weed eaters?
