Short on time and want my #1 recommendation?

If I had to recommend you only one (4-stroke) string trimmer, it would be this Husqvarna 324L Straight Shaft Weed Eater.

While it’s not the least expensive, it can handle anything you throw at it, and both homeowners and professionals will appreciate its benefits.

Overall, the price and durability make it a solid piece of lawn equipment that I feel confident enough can fit almost anybody’s needs. It feels good in the hands and has the quality that only Husqvarna can provide.

What we’ll be going over today:

The Best 4 Stroke Weed Eaters

Craftsman WS405

Husqvarna 324L 4-Stroke Weed Eater. Best for Home Commercial Use

If you’re looking for a do it all kind of gas trimmer; one that can handle any home yard with ease or cut through your commercial jobs like a champ, then you’re going to love the Husqvarna 324L String trimmer.

From a well designed, 18” cutting width trimmer head that reloads string line easily to its easy start, smooth-running operation, you’ll find that you’re getting the job done quicker and more efficiently, every single time.

A Robust (Work of Art) Trimmer Head

Your weed eater’s head is the part of your equipment that you want to be designed the absolute best. Luckily, Husqvarna did exactly that with the 324L.

The head can easily release more line by simply tapping it on the ground. This makes your job so much easier by effortlessly allowing you to keep working. Gone will be the days of having to stop and manually pull out more line.

Next, you can use any size trimmer line that’s available (.095 to.105). You might be wondering why this even matters, but by using the stronger line you can cut through thicker brush, weeds, and debris that may be around your property.

The only downside to this trimmer head is the fact that it doesn’t have a pop-off lower, so you won’t be able to use any aftermarket attachments trimmer.

Smooth, Yet Powerful Operation

Combine this string trimmer’s four-stroke motor and straight shaft design, and you’ve quickly got a powerful piece of equipment on your hands.

The noise on the Husqvarna 324L is considerably lower than most others and you won’t get any shaking or vibration, all thanks to the shaft design.

It feels smooth in your hands, but you know that you are working with something powerful by how it cuts through grass and weeds like a knife through butter.

My Final Thoughts

I really like this weed eater and it’s one of my favorites. but I’ll be straight up: it’s not cheap! However, you really do get what you pay for. You’ll be investing in a solid piece of solid equipment that’s backed by a really good company. If you can get over some of the minor cons like the price and not having the ability to add any attachments, then this will be a complete winner for you!

Click here to read through all the Amazon reviews for the Husqvarna 324L and I think you’ll quickly see why it’s rated as my most recommended.

Craftsman WS405 Straight Shaft Trimmer. Best for The Money

If you have a small yard and you are looking for a four-cycle weed wacker that gets the job done reasonably well, then the Craftsman WS405 may be worth a deeper look.

With its easy (2 steps) prime n’ pull start and accepting an array of attachments. essentially making it a jack of all trades, this Craftsman straight shaft weed eater can deliver for most homeowners.

The cons I found with this trimmer is the fact that it’s reasonably heavy and there is a design flaw with the bump cap that makes replacing string harder than it needs to be.

Prime Pull. You’re Ready to Go

Having a weed eater that can easily start makes life so much easier. Being able to just prime, pull and go (on the very first pull) with the Craftsman WS405 makes using it such a breeze.

You’re going to feel confident knowing that you won’t be spending more time fidgeting with a piece of equipment just to get it started, than actually using it!

Go Attachment Crazy

If you’re looking for a string trimmer that can accept a list of TrimmerPlus attachments, then this is going to be right up your alley.

The Craftsman WS405 can accept all of these attachments below (which are conveniently available on Amazon):

My Thoughts

Listen, if you’re a homeowner with a smaller yard and you want a lot of different attachments that can really make this a one and done type of tool. then I would recommend the Craftsman WS405. Personally, I think it’s the best 4 stroke weed eater for the money.

It is a little on the heavier side (which you may or may not get used to) and many people have complained about Craftsman over-tightening the nut on the bump cap which makes it hard to restring. If you can get over these two minor annoyances, then I think you’ll be happy with the versatility this 4 cycle string trimmer provides.

Troy Bilt EC (Four Stroke) String Trimmer. Best for Small Yard, Home Use

If you’re a homeowner who wants the ease and reliability of a 4 stroke trimmer that is going to get a “weekend only” type of use then you’ll probably want to take a look at the Troy Bilt EC 17” Weed Eater.

With its lightweight (compared to the other two in this guide) frame and soft pull-start, it’s a decent trimmer if you’re not looking for the top of the line perfection.

Lightweight Frame

Anyone who has been around power equipment long enough knows that having to use something heavy (weekend after weekend) can become a real pain.

While the Troy Bilt EC still has a 4 cycle motor, making them heavier to begin with, it’s lightweight (only 11lbs) compared to the other two in this list

Correct Way To Point Arrow On 2 Stroke Engine Pistons. #shorts

If weight is a huge factor for you and you just want the lightest of the three, then this should fit your needs.

Soft Pull-Start

One major advantage of this string trimmer is just how easy it starts. and that makes a world of difference.

You may be used to other weed eaters that take all your strength just to get started, but the Troy Bilt EC only needs a light pull and it should fire right up.

My Thoughts

It’s a good weed eater for the average user. It doesn’t do anything exceptionally well, but it gets the job done that it was made for. Definitely not my favorite, but I’ve also seen worse!

This 4 cycle string trimmer can have a lot of little quirks, so you need to make sure to read the manual fully and understand proper start-up procedures, etc.

Still not sure? Don’t just take my word for it:

How I Picked

Picking these three string trimmers wasn’t easy, but I’ll share the criteria I used when making my decision:

    The Brand: For me (and you), it’s really important to pick reputable brands when we are choosing a piece of power equipment. All three of these brands (Craftsman, Husqvarna, and Troy Bilt) create a solid, wide range of lawn and garden products that have a good reputation in the industry.

What is a 4 Stroke String Trimmer?

If you’ve been looking around at power equipment lately, then you’ll likely have noticed a new technology making its rounds – the 4 stroke engine. So, what exactly is it and how do they work?

4-Cycle Engine Explained:

A 4-cycle engine does almost the same thing as a 2-cycle, but it takes two more strokes to complete a cycle.

The 4 stroke cycle looks something like this:

Step 1) Intake – As the piston moves into a downward position, the pressure is allowed to push the air-fuel mixture into the bore of the cylinder.

Step 2) Compression – The air-fuel mixture gets compressed between the cylinder head and the piston.

Step 3) Power – The piston is in the perfect position to ignite the gas. This is where all the magic happens and gives power to your equipment.

Step 4) Exhaust – As the piston reaches the center once again, the exhaust valve opens and pushes the used gases out of the exhaust system. Once the piston reaches the center again, the 4 stroke process will repeat

Stroke vs 2 Stroke Weed Wacker

Now that you understand how a 4 cycle engine works, you’re probably wondering what exactly are the benefits and are they really better?

Advantages of a 4-stroke vs a 2-stroke

There are many advantages to getting a 4 stroke weed eater over a 2 stroke:

  • Saves you time by not having to pre-mix oil and fuel
  • Makes more torque at lower RPM’s, which allows for a more durable, longer lasting engine
  • Cleaner burning emissions so you don’t have to smell gas and oil while you work
  • Better fuel economy, which is going to save you money on fuel in the long run

Disadvantages of a 4 stroke string trimmer

While it may seem like four cycle trimmers are the hands down winner, they don’t come without their own set of disadvantages :

  • complex to build, which means they’re harder to repair if something goes wrong
  • Usually more heavy (although new technology is finding ways to make them even lighter)
  • frequent oil changes required

Straight or Curved Shaft: Which is Better?

Many weed eaters (not only 4 cycle) come in straight or curved shaft options. You’re going to have to decide which style fits you best.

Straight Shaft

Straight shaft weed eaters are a great, versatile option. They make getting into hard to reach spots so much easier. They usually have less vibration because of their extra weight and tend to be a little more powerful than a curved shaft.

I find straight shaft designs great if you have a lot of different areas and hard to reach places you need to get into with your string trimmer. They’re usually capable of accepting different attachments for other jobs, as well.

Curved Shaft

Many people find curved shaft weed trimmers more comfortable to use since they are (usually) lighter in weight and have a natural curve that allows the head of the weed eater to sit closer, allowing for more control.

Personally, I find curved shaft easier to do other tasks such as edging lawns and quickly cutting down weeds out of the cracks of concrete.

How To Choose a Weed Eater

If you’re anything like me, you want to know that you’re investing your money into the right piece of equipment, am I right?

So below, I’ll break down some key things you should be looking for when picking the best 4 stroke weed eater:

In my opinion, the size of your yard is going to determine almost 90% of what type of weed eater you decide to buy. Pick one that isn’t meant for the job you’re going to be doing and it’ll be a pain every single time you take it out.

If you have a medium to large sized yard. then I really recommend you choose something that’s going to be more on the professional side of things. You want it be able to handle the amount of work you’re going to throw at it and stay durable.

If you have a small yard. you can get away with a weed wacker that’s more suited for light, home use.

Making sure you stick with major brands (like Husqvarna. Craftsman. Troybilt. Steel. etc.) and checking their warranties is always critical. The last thing you want to do is get an off-brand weed eater that doesn’t offer a robust warranty and be left with a hunk of junk that sits collecting dust.

What Other People Say (Reviews)

Spend your time and do your due diligence. Each of the string trimmers I have listed on this page have many, many reviews on Amazon from others who use the equipment. Don’t just take my word for it, but look and see what others have to say about the weed eaters you’re interested in. When it’s all said and done, I want you to be informed and able to make a Smart purchase!

String trimmers are known by many names (Weed Eater is actually a brand name). If you are looking to buy a gas-powered model, there are two different types of gasoline engines available: 2-cycle and 4-cycle.

2-cycle and 4-cycle string trimmers each have advantages and disadvantages depending on your priorities and needs:

  • 2-cycle weed eaters tend to be lightweight, easy to maintain, and affordable but are louder and not environmentally-friendly
  • 4-cycle weed eaters are usually quieter and produce lower emissions but they tend to be more expensive and heavy.

The pros and cons will be discussed in detail, as well as how 2-cycle and 4-cycle engines function. Each engine has positive and negative aspects that need to be considered before you invest in a weed eater.

What Is the Difference Between 2-Cycle and 4-Cycle String Trimmer Engines?

2-Cycle 1. Lightweight2. Easy To Maintain3. Affordable 1. Not Environmentally-Friendly2. Loud3. Gas and oil must be mixed at a specific ratio
4-Cycle 1. Quieter2. Lower emissions3. Don’t have to mix gas and oil 1. Higher cost2. Heavy

2-cycle and 4-cycle engines are sometimes referred to as 2-stroke or 4-stroke engines. This type of engine isn’t specific to weed eaters; chainsaws, edgers, and other gas-powered yard tools use these types of engines too. Regardless of the brand or type of yard tool, they will have the same basic combustion process that makes them run.

Both types of engines are powered by gasoline. The 2-cycle and 4-cycle engines are specific to gasoline engines. There are electric yard tools, but those engines function differently and don’t have the same stroke processes as gasoline engines.

How 4-Cycle Engines Work

The 4-cycle engine has several moving parts. It has a crankshaft, camshaft, a connecting rod, multiple valves and lifters, and a piston. It also has four basic stages that are completed in two revolutions, which is why it’s called a 4-cycle or 4-stroke.

The four cycles of a 4-stroke engine are:

Each stroke, or cycle, completes one part of the 4-cycle process (source).

How 2-Cycle Engines Work

The 2-cycle engine goes through the same process but with fewer steps and has fewer parts. A 2-stroke only has a crankshaft, a connecting rod, and a piston.

It only takes one revolution to provide power, release exhaust, intake air, and compress that air. When the piston goes down, it creates power and releases exhaust. When it moves upwards, it takes in air and compresses it.

Because it can do the same amount of work in fewer strokes, 2-cycle engines create a more powerful machine. They are smaller than the 4-cycle engines because they don’t have as many pieces and don’t weigh as much.

How Are 2-Stroke And 4-Stroke Engines Lubricated?

Engines have to be lubricated so they can continually run smoothly. If they don’t get lubricated, they can wear out faster.

2-cycle engines use a mix of gasoline and oil in the same chamber. As the gasoline moves through the engine, the oil moves along with it and lubricates all the parts. 2-cycle engines typically require a specially formulated oil that you mix with gasoline.

Too little or too much oil can damage the engine, so be sure to read the manual that comes with the weed eater to find what ratio you need.

Note: 2-cycle oil can go bad so be mindful of how old it is when adding it to gas.

4-cycle weed eaters have separate compartments for oil and gas, so technically you can use the same kind of gasoline you use in your car for your weed eater, however, it is extremely important that you use gas with 10% or less ethanol to avoid damage.

I’ve grown partial to skipping the pump and using an ethanol-free fuel (link to Amazon). Ethanol-free gas is a great solution for gas-powered yard tools and allows you to completely avoid the moisture issues that cause so many issues.

You will also have to have oil in the second compartment. Since the oil and gas are separate, you will have to change out the oil. A good rule of thumb is to change the oil after twenty-five hours of usage. Most people that I know usually change the oil once a year at the beginning of the season.

The Pros and Cons of 2-Stroke and 4-Stroke Yard Tools

Before you make a purchase, you should consider the pros and cons of each engine. Each one has features that make it a valuable tool. But, they also have their downsides.

4-cycle, 2-cycle, weed, eaters

The key aspects to be compared are weight, power, fuel efficiency, noise levels, maintenance, and price. Each aspect is an important part that should be considered when making a purchase. Not every favorable aspect can be present in a weed eater, of course, so you need to decide which are most important to you.

Here’s the short and sweet of it. Read on for details on each section.

Feature Comparisons Between 2-Stroke and 4-Stroke Engines

Because 4-cycle engines have a longer process that uses more parts, the engines are typically bigger, which results in a heavier weed eater. A heavy machine can be difficult to maneuver, so you might end up with uneven lawn edges, especially if you’re teaching your child how to properly use it.

Many 4-cycle weed eaters need to be kept level so the oil will continually lubricate the engine. If they are tilted to the side for too long, the oil can’t be evenly distributed, and it will have the potential to damage the engine. If the weed eater is too heavy for the user, this might be a difficult task.

2-cycle weed eaters are lighter because they have fewer parts inside, so it should be easier to handle. You’ll be able to have better precision and get straighter edges on the lawn if you’re not struggling to carry for extended periods of time.

The 2-cycle weed eaters don’t have to be kept level. Since the oil is mixed with the gas and has a different lubrication system, it can be held at any angle. This will also make it easier to handle since you don’t have to worry about how you hold it. This might also be beneficial if you have a uniquely shaped lawn with difficult angles.

The 2-cycle weed eater has the advantage if you want to purchase a weed eater that the whole family can use since it’s lighter and easier to handle.


Torque is the power that’s created by the engine that causes the blades of the weed eater to turn. 4-cycle engines produce more torque, giving you more power to work with. Because of the torque, 4-cycle weed eaters can cut through grass easily. If you have a particularly thick patch of grass, you will get through it quicker with a 4-cycle weed eater rather than a 2-cycle. 2-cycle weed eaters should still be able to get any job done, but you may have to work a little harder for it in some areas.

Since 4-cycle weed eaters are heavier, its power is beneficial because it will allow you to spend less time with the machine since it can cut through grass faster. If you have to spend more time with the lightweight 2-cycle weed eater, you may feel the same amount of fatigue as if you had used a 4-cycle.

4-cycle weed eaters have the advantage if you want to glide right through the grass and get the job done quicker.

Fuel Efficiency

4-cycle weed eaters burn cleaner and do not create as much pollution. The 4-cycle doesn’t cause as many fumes while the engine runs as the 2-cycle weed eater does. Since the gas and oil are kept separate, it doesn’t burn oil as it burns the gas, so you’re getting more usage out of the fuel.

Since the 2-cycle weed eater keeps gas and oil together, it will burn the oil and pollute the air with exhaust fumes. The burning oil is what causes more pollution. As more people grow concerned about pollution and climate change, it’s possible that 2-cycle weed eaters won’t be allowed one day because of how much pollution they release.

The 4-cycle weed eater has the advantage when it comes to fuel efficiency. fuel being burned means less time trimming, so you will get more time out of the 4-cycle.

Noise Levels

The 2-cycle weed eaters are typically louder than the 4-cycle. This is because its process is completed in just two strokes. The 4-cycle engines have four strokes. The third stroke, the intake stroke, closes up a cylinder inside the engine that makes it quiet. The 2-cycle engines don’t have a feature like that, so they will usually be pretty loud.

I always wear noise-canceling headphones when doing yard work with gas-powered tools. I strongly recommend hearing protection.

The 4-cycle weed eater has the advantage if you want a quieter machine. This can be beneficial if you live in the suburbs and don’t want to be disruptive to your neighbors.

Note: If noise levels and fuel efficiency are major concerns for you, it’s worth considering battery-powered string trimmers. These have come a long way in recent years. See Gas vs Electric: 6 Reasons To Use Battery-Powered Yard Tools


Okay, so just hear me out on this. A lot of people argue that 4-stroke engines are more reliable. I can agree with that. But here’s the thing…

2-cycle weed eaters have fewer parts that can break. Remember that its engine has three main parts, a crankshaft, a connecting rod, and a piston, while the 4-cycle engine has those three parts along with a camshaft, valves, and lifters. pieces mean you have more parts that could potentially break.

A 2-cycle weed eater may be easier to repair at home than a 4-cycle since it has fewer parts. There’s just less that can go wrong with it.

If a 4-cycle engine breaks and you aren’t too savvy with repairing engines, you may have to have it professionally serviced. Hiring a repairman will cost you more money, especially if you end up with a weed eater that needs multiple repairs.

Now in fairness, there is another side to this story. Two-stroke engines run at a higher RPM in general. And so, they can wear down the internal parts quicker. This means that they can break down more often, theoretically at least (source). That makes 4-strokes appealing for some.

But 4-strokes do require more ongoing routine maintenance. You have to change the oil each season, for example. That’s not something you have to worry about when it comes to two-strokes. Yes, you have to mix the oil and gas but not if you use a commercial premix like I do.

All in all, 2-cycle engines have a slight advantage when it comes to routine maintenance but 4-cycle engines have the edge in longterm durability. There are really some solid arguments on both sides for this one so maybe we call this section a toss-up.


In a perfect world, you’d make your decision solely based on your preferences. But realistically, you have to keep your budget in mind, and that’s typically the deciding factor when it comes to buying yard equipment, isn’t it?

Weed Eater Cost: 2-cycle vs 4-cycle

Basic run-of-the-mill 2-cycle weed eaters typically average between 100 and 200, but the price can go above and below this range depending on the brand and model.

4-cycle weed eaters average between 150 and 350. Again, the price will vary according to brand and model. 4-cycle engines are bigger and have more parts, so they cost more to manufacture and result in a larger price tag.

As you look at prices, be sure to research which brands are trusted and are of high quality. The cheaper weed eaters are probably going to break down more often, which means you might have to spend quite a bit of money on repairs or replacement parts. Consider that repairs will add to the long term price you invest in the equipment.

Gas and Oil Costs

Both types of weed eaters require gasoline and oil to function. 2-cycle weed eaters use less oil but 2-stroke oil is usually more expensive.

4-cycle weed eaters usually require SAE 30 oil in its own compartment. You can usually buy a quart of SAE 30 oil for about 12. You have to keep enough oil in the compartment to keep the engine lubricated, and you have to change out the oil just like you change it in your car.

You should change it after a total of 25 hours of usage. Many people just change it annually at the beginning of each season. So, the price of oil will probably end up being more expensive over time than the oil for 2-cycle weed eaters.

Which Has the Price Advantage?

This can be a little more complicated since there are several factors that go into determining the best price. Cheaper doesn’t necessarily always mean it’s a better deal. So, let’s create a summary of possible for each.

For the 2-cycle weed eater:

  • The average price is about 150.
  • Oil can be purchased for about 10.
  • You won’t have to buy oil very often.
  • It’s easier to repair yourself.

For the 4-cycle weed eater:

  • The average price is about 200.
  • Oil can be purchased for about 12.
  • You will probably buy oil more frequently.
  • It may be more difficult to repair yourself.

The 2-cycle weed eater has the advantage based on numbers alone. Remember that brand, model, and how much you want to spend on fuel and oil will affect how much you spend. If you want the cheapest option available, you risk sacrificing quality.

There are two types of weed eaters: 2-cycle and 4-cycle. The difference is how the engine works. The 2-cycle engine uses one revolution to complete the cycle while the 4-cycle uses two revolutions to complete the process of creating power and bringing in air, and then release exhaust and compress the air. Since each engine completes the same process differently, they are different sizes, weights, and require different fuel methods.

The pros of the 2-cycle include:

The cons of the 2-cycle include:

The pros of the 4-cycle include:

The cons of the 4-cycle include:

Which is the best option for you? If you need a weed eater for lawn care at home, the 2-cycle weed eater might be the best option. Because it’s lightweight and easy to control, several family members will be able to use it, and it should be less strenuous, so you don’t have to wear yourself out every time you use it.

If you have tough grass to cut or care about your carbon footprint, the 4-cycle is probably better suited for you. It’s heavier and will feel like more of a workout, but it’s great for tough jobs. If you have a lawn care business, you might prefer this weed eater, especially if you want to get more use out of your fuel and use it for longer periods of time.

Best 4 Cycle Trimmer Reviews [year]

If you are a homeowner or a lawn care professional thinking to invest in a new string trimmer in [year], you might be confused about what model to choose due to the multitude of string trimmers available on the market.

With so many models and so many characteristics, it might be difficult to decide which is the right tool for you.

For this reason, today I am going to talk about the 4-cycle string trimmers, explaining why they are better compared to the 2-stroke tools.

I also made a list of the best 4 cycle trimmer reviews to help you choose the best one for your lawn care.

AT A GLANCE: Our Top Picks for 4 Cycle Trimmers

Why Should You Buy A 4 Cycle Trimmer?

When it comes to buying a gas-powered string trimmer, you will basically have to choose from two options of engines, 2-cycle or 4-stroke engines.

Most users are accustomed to the 2-cycle weed eaters, and many homeowners even believe that 2-cycle engines are better because they are more powerful and more lightweight. So, why should you buy a 4-cycle string trimmer?

Well, the main reason is because they deliver better results.

4-cycle, 2-cycle, weed, eaters

A 4-cycle engine produces more torque, a characteristic that will allow you to cut with an incredible ease through any type of grass and weeds. But this is not the only reason to choose a 4-cycle tool.

In addition to generating more torque, the 4-cycle engines produce fewer emissions, thanks to the way they are built. In fact, most of the 4-cycle engines are CARB compliant, a feature that you might find really useful.

When it comes to starting the tool, the string trimmers powered by 4-cycle engines start faster, which is a further reason to choose a tool with a 2-cycle engine.

The string trimmers powered by 4-cycle engines are also more comfortable to use. First of all, they are quieter compared to the 2-cycle engines, an important aspect especially if you are going to use the trimmer for long periods of time. Secondly, the tools powered by 4-cycle engines produce fewer vibrations. This will reduce the fatigue and you will be able to use the tool for a longer time.

The only downside of the 4-cycle engines is that they are heavier compared to the 2-cycle ones. However, this minor disadvantage can be easily overlooked if you choose a quality trimmer that is well balanced.

Now that you know why you should choose a 4-cycle trimmer, let’s find out what other things you should consider before deciding which tool to buy.

How To Choose A String Trimmer

The most important aspect of a string trimmer is, without a doubt, the cutting performance. If you want to make sure that the model you choose is reliable and durable, here are a few things to consider:

  • Cutting string: depending on the characteristics of your lawn, you should choose a string trimmer with a thinner or with a thicker cutting line. There are a variety of models available on the market, but if you want to achieve professional results I suggest to choose a tool that uses a cutting line with at least.095 inches in diameter.
  • Line feed: the bump feed spools could be annoying to use, but will allow you to have a better control on the amount of line that is used. On the other hand, the automatic feed spools will make trimming easier, but these tools might waste a lot of line. Based on your personal preferences, you should choose the type of trimmer that suits your needs.
  • Cutting width: depending on the size of your lawn, you should choose a string trimmer with a cutting width between 10 and 12 inches. If the lawn is larger, you could even search for a model that has a cutting width larger than 12 inches. Some manufacturers also produce string trimmers with adjustable cutting swaths that are more versatile to use.
  • Cutting attachments: if you have to deal frequently with tall grass or stubborn weeds than you should also consider the possibility to replace the cutting line with a cutting blade. Some manufacturers propose some models of string trimmers with these characteristics.

Besides the cutting characteristics, you should also consider the ease of use and the comfort. Therefore, you should choose a tool with the following characteristics:

  • Telescopic shaft: this feature will allow you not only to adjust the length of the shaft to your own height, but it will also allow you to trim the grass from the hard-to-reach areas of your lawn. If the tool you like doesn’t have a telescopic shaft, at least choose one with a long shaft.
  • Adjustable handle: in addition to the telescopic shaft, you should also check the possibility to adjust the handle’s position. When it comes to the handle, you should also choose a model with an ergonomic handle and it would be even better if the handle is padded or provided with another type of soft-grip, as this feature will reduce the level of the vibrations.
  • Anti-vibration system: besides the padded handle, a tool that is equipped with an anti-vibration system is more comfortable to use. Balance: even if the 4-cycle tools are probably the heavier models, if the gravitational center of the engine is properly balanced, the tool will be extremely comfortable to use.

The last thing to consider is the versatility of the tool. Some string trimmers are manufactured as dual-function tools, featuring cutting heads that can easily transform from trimmer into an edger, while others accept a series of attachments that completely transform the string trimmer into another outdoor tool.

Depending on your necessities, you should decide what type of string trimmer to buy. Now, read the best 4-cycle trimmer reviews and choose your tool.

Husqvarna 4 Stroke Trimmer 25cc/324 L Review: Does the Honda Engine Elevate This Above Other Weed Eaters?

I hope you love the products that I recommend here! Just so you know, I work with Amazon and other affiliate partners and may be compensated from the links below.

Above: This Husqvarna is well made and has a lovely Honda engine

Essentially that means a couple of things – it takes four steps to create power – with each step being more concentrated in comparison to a 2-stroke engine.

With four stroke engines the torque is much nearer the base of the unit meaning you barely have to apply any gas to get a good amount of power. Just above idle will provide you with plenty of power to trim.

And another benefit of 4-stroke engines?

They run purely on standard gasoline, you don’t have to mix gas and oil, which makes things a lot easier. Simply put in the gas and you are good to go.

Also with 2-stroke engines the smell of 2-stroke gas inevitably seeps into your clothing, so you don’t have that issue easier.

This is nicely made – it is pretty much all steel and metal, with just a couple of plastic pieces. It is a quality commercial style unit with the (previously mentioned) great Honda engine detached and built onto the shaft.

It is also easy to assemble, start and use – there is almost no resistance on the recoil. Small details like the soft grip, adjustable handle make it really comfortable to use and elevate it above most other gas trimmers on the market.

But you’re probably wondering…

Do I have to constantly refill the string?

Well it uses a T35 Husqvarna trimmer head which is huge and holds so much string, I’d estimate maybe up to 40 or 50 foot of line, which is pretty much unparalleled and means you don’t need to stop to fill it up as much.

Quite often with two stroke engines they bog down when you flip them over to edge, whereas this works flawlessly when you do so – the engine keeps purring away and you can easily and quickly tidy up your yard.

The Not So Good

The guard on this is not perfect – it doesn’t protect you from the grass you cut.

In fact the chances are that, as you will probably be using this to cut down substantially overgrown grass and weeds, you could be left covered in grass at the end of it all. It could definitely do with improvement.

The string is also quite close to the top of the trimmer head, and this makes cutting grass in really tight spots a little more of a problem. It isn’t a big problem, but something to be aware of.

4-cycle, 2-cycle, weed, eaters

Where the air filter cover sits with the main plastic frame is not as well protected as it should be. I had some issues with the clips breaking off – so this could be made more secure.

Gas vs Electric Trimmers #stihl

Also as you are not mixing fuel there is no tinge to the fluid in the fuel tank. The fuel tank is also made of solid white plastic.

A combination of these two factors means you have no idea how much fuel is left in the tank unless you open it and look every time. A slightly transparent fuel tank would make this a lot easier.

Price wise it is also at the higher end of the market – although there is a reason for that – namely the power and quality you get!

Above: The Husqvarna 4-stroke trimmer is at the higher end of the market price wise.

What is the best commercial string trimmer on the market?

Well, I imagine you are looking to get the best bang for your buck when investing in your lawn care equipment!

If so, good news! We asked over 1000 landscapers what their favorite string trimmer was, and the result is clear.

And at the end of the day, one brand stood tall about the rest!

Want to find out what the favorite weed eater among lawn care pros is?

What to Look For in a Commercial String Trimmer

It’s no secret, there is a huge difference between selecting a weed eater for your own personal use, than when you are looking for one to use commercially.

While a Ryobi 4-cycle Expand-it may be an excellent choice for the average homeowner.

When it comes to operating a professional lawn care company, you likley want to consider something else.

Here are a few things to keep in mind when selecting a commercial weed whacker.

1. Get a Straight Shaft (Never Curved)

One of the biggest mistakes you can make when purchasing a string trimmer is to go with a curved shaft.

There are a couple reasons straight shafted string trimmers are much more effective than curved trimmers for commercial use.

Curved Trimmers are Shorter

Curved string trimmers are shorter by design. Unless you are 5 feet tall, or have a small space to manage. A curved string trimmer will likely cause you to hunch over, and cause long, painful days.

Curved Trimmers are Less Dynamic

Unlike a straight shafted trimmer, curved trimmers are not as dynamic.

Though they may help you maintain a more level cut, they are more limited.

For example, curved trimmers can not be easily turned on their sides to edge, or get in tight spaces.

Trust me, stay away from any curved weed whacker if you really want to weed eat like a pro!

Go with Gas!

It’s true, battery-powered tools have come a long way, BUT when it comes to commercial lawn care operations, they are not up to par.

Always stick with a good ole’ 2-stroke or 4-stroke weed eater. Either of these will be a better option than the current battery-powered options.

Single Purpose or Multi-tool String Trimmers?

Look, this one really depends on how your business is set up.

If you are Looking for The Best of the Best

If you are looking for a trimmer that can help you knock out 10 lawns or more in a day. You really should stick with a solid shaft string trimmer and stay away from the multi-purpose weed whacker designs.

Think about it, you are going to be using your trimmer a few hours everyday. The more efficient the weed whacker is, the more time you can save on each lawn.

Multi-purpose for New Operations

On the other hand, if you are just getting started with your lawn care or landscaping business. And you are looking for a low-cost multi-function tool, then a ‘multi-tool’ string trimmer may be a good temporary option. Especially if you want a tool that can be used to clear brush and do regular weed eating on the same day.

For my first year of operation. the multi-tool Ryobi helped me get off the ground allowed me to offer a wider range of services until I was able to FOCUS solely on lawn care.

4. Get a Trimmer that can Handle.095 String

Personally, I mostly use.095 string.

Here’s why.095 string is light enough to not be too much, but strong enough to take on some pretty thick grass. Additionally, with proper handling, it is thick enough to edge when needed.

In my experience. if you need anything thicker you can either use a metal blade, or you simply need a different tool.

What string trimmer brand is the best?

Well, we polled over 1000 landscapers, and the winner was VERY Clear.

As you can see from the results below, there is one obvious winner!

Honestly, I was shocked by how much the winner stood out from the rest.

Over 50% of lawn care professionals opt for Echo brand string trimmers.

And no, this poll was not sponsored by Echo.

Based on the response from lawn care pros here is what we learned about why they prefer Echo trimmers.

Why Lawn Care Pros Love Echo String Trimmers

So why do lawn care pros rave about Echo trimmers?

Let’s see what they had to say!

Starting is a Breeze

Sheli Groat from Groat Mowing and Snow in Otho, IA told us that here Echo trimmer always starts when she needs it too!

She also mentioned that the bump feature always works properly!

In my experience, the bump feature is typically the first thing to fail. So that is certainly an important feature to look for in a commercial weed whacker.

Fairly Priced and Reliable

Michael Sterba of Murfreesboro, TN said he likes Echo because they are fairly priced and very reliable!

It’s true, Echo’s pro string trimmers are very affordable.

Less Down Time

Troy Mosley of Mosley Lawn Service in Tulsa, OK said that he prefers Echo’s weed whackers had 0 down time during the entire season!

All Around Beast

Jim Mullins of Exceptional Lawns says that his Echo string trimmer “is just a beast”!

He particularly recommends their SRM-3020 model which starts at 399.

Additionally, he also reiterates Sheli’s statement that they are very easy to start.

Other Notable Weed Eaters to Consider

Again, this post is not sponsored by Echo, and I would like to suggest other trimmers you may want to consider.

Husqvarna’s Pro Line of String Trimmers

Husqvarna is on par in many ways with Echo, and STIHL. Honestly, it is difficult to say which brand is truly better across the board.

I have had nothing but great experiences with Husqvarna’s pro line of trimmers. In fact, they last years with little maintenance. The one downside I would have to say is the poor quality of the trimmer head. The bump heads of their weed whackers deteriorate rather quickly.

With that being said, Husqvarna’s 324L is a good option if you are looking for something a little cheaper, with a quality build.

STIHL’s Pro Line of String Trimmers

Stihl trimmers are the second choice among lawn care pros when it comes to commercial string trimmers.

Here’s the deal, STIHL offers a great line of gas-powered products. Although I have never owned a commercial STIHL trimmer, I do prefer their chainsaws far beyond any other brand I have tried, and based on that I would assume their weed whackers are a great option too.

If STIHL is your only option, you can rest assured that you are going to get a great product. Check out the STIHL FS 460 C-EM.

Ryobi Multi-Use Weed Eater

Look, people can say whatever they want. Let’s face it, not everyone can afford a 400 weedeater for their business.

In fact, the first lawn care tool I owned was the Ryobi expand-it with the string trimmer head, along with the metal blade head. And it did what I needed it to do until I was able to take my lawn care business to the next level.

Additionally, the Ryobi trimmers offer the ability to use.095 size string, for about 200. Seriously, if it’s all you can afford to get your business started.

There is no shame in doing what you have to do!

The Bottom Line on Choosing a Commercial Trimmer

At the end of the day, the lawn care professionals have spoken. Echo is the champ!

However, that is not to say that other brands are not also worth testing out.

The most important thing is that you know what you are looking for in a string trimmer.

Ideally, you want a straight shafted gas-powered weed whacker, and is able to handle.095 sized string.
