Lawn mower in a uniform with equipment. Commercial 4 cycle weed eaters.

1. Husqvarna String Trimmer

Originally known for manufacturing high-performance bikes, Husqvarna has made significant forays into the market of household power tools. And with high-quality products like the 324L string trimmer, the brand has gained a considerable reputation as well. It is a highly popular gardening tool thanks to its powerful performance and ease of use.

Why Did We Like It?

The 25-cc gas-powered engine that this weed eater comes with packs quite a punch. It generates 0.9 horsepower, which is pretty commendable for a string trimmer of this size. Because of that, it can spin the wide trimmer head at relatively high speeds, which makes cutting through any type of weed a breeze.

Since it is a 4-cycle engine, you don’t need to mix fuel and oil together manually, which improves convenience. On that note, the engine uses unleaded gas, which makes it a sustainable choice. What’s more, the smart start trimmer technology ensures that you can start it up 40% quicker than other trimmers, which saves you a lot of time.

This weed eater comes with a T25 trimmer head, which has been designed to make line reloading easier. And with the unique Tap ‘N Go line release feature, feeding more string for cutting grass is as easy as pressing a button. Furthermore, it has a translucent fuel tank, which allows you to monitor gas usage conveniently.

What Could’ve Been Better?

There is only one complaint that we have with this particular string trimmer, and that is its price. It is much more expensive than other similar commercial 4-cycle string trimmers. Because of that, many users may be driven away from purchasing this particular product.

Pros
  • Releasing and reloading lines are easy
  • Startup is fast
  • Uses sustainable fuel
  • Monitoring fuel usage is convenient
Cons
  • Relatively expensive

2. Black+Decker String Trimmer

When it comes to power tools, Black+Decker is a fairly popular brand. Likewise, its 25A-26S5736 4-cycle string trimmer is popular among customers, too. This can be attributed to the high-quality build and powerful engine that makes it one of the best commercial weed eaters available today.

  • 22-INCH CUTTING SWATH: Unique shape makes trimming...

Why Did We Like It?

The biggest highlight of this particular gas weed eater is its heavy-duty engine, which has a capacity higher than most other 4-cycle weed eaters. It comes with a unique fuel filter that helps to enhance performance even further. There is also an Auto Choke feature that makes the startup process quick and clean.

Furthermore, the 22-inch wide cutting swath allows you to clear out large portions of thick weeds in a short time. And the unique line shape and offset trimmer head design ensure that you can access all the hard-to-reach areas on your lawn. As a bonus, the comfortable folding handle and the large ball-bearing wheels make the machine sufficiently maneuverable.

The machine has a wide cutting deck that is made of rugged steel, which makes it durable enough to handle any type of weeding activity. Moreover, with the single lever height adjustment, you can conveniently change the position of the deck.

What Could’ve Been Better?

Due to the high-capacity engine, the weed eater has a bulkier size, which can make it a bit inconvenient to use compared to other commercial string trimmers. The larger size makes it a bit difficult to store as well, which can be problematic for many users.

Pros
  • Easy to maneuver on any terrain
  • Cuts through large sections in a short time
  • The startup process is quick and simple
  • Easily adjustable height
Cons
  • It has a bulky design

3. Craftsman Weedwacker

The Craftsman brand has carved out a considerable niche for itself thanks to its diverse lineup of highly reliable household tools. And the WS4200 Weedwacker is no different, which is why it is held in such high regard by professionals and DIYers alike. It is a very silent weed whacker that comes with a lightweight design.

  • EASY 3-STEP STARTING: Prime, Choke, Pull. COMFORT:...

Why Did We Like It?

Despite having a gas-powered engine, it has a very clean operation and does not generate any harmful fumes. Also, the 4-cycle engine eliminates the need for mixing oil and fuel, which makes it convenient to use. It has a simple 3-step startup, where you need to prime, choke, and pull the cord to get it up and running quickly.

Thanks to the 17-inch wide cutting head, you can clear thicker weeds over a large area in an instant. In this regard, the straight shaft and the high-capacity easy-winding bump head continuously feed a 0.095-inch thick line through the trimmer. Because of this, the weed removal process becomes quick and convenient.

Additionally, this gas string trimmer comes with a unique over-mold handle, which has an ergonomic design for maximum user comfort. Besides, it is compatible with the TrimmerPlus multi-yard tool system that allows you to easily replace the head with other attachments, which makes it a versatile option.

What Could’ve Been Better?

While the trimmer does an excellent job of feeding the line through the head, reloading the spool after it has run out is a bit difficult. As such, we think that the advantage of continuous line feed is lost due to this one aspect.

Pros
  • Clean and effective engine operation
  • Ergonomic grip design
  • Helps to remove weeds quickly
  • Highly versatile
Cons
  • Reloading the spool is difficult

4. PowerSmart Cordless String Trimmer

PowerSmart is a brand that is known for its heavy-duty lawn care tools, which is why we included the brand’s cordless string trimmer in our list. It is a versatile weed eater that comes with an affordable price tag, which means that you get excellent value for your money.

  • 🍀2-IN-1 TRIMMER/EDGER: This gas weed wacker can...

Why Did We Like It?

This product comes with an air-cooled, vertical piston valve engine, which provides enough juice for tackling most weed-trimming activities. Despite having such a powerful engine, it produces very little vibration, which makes it easy to handle. Of course, this is further assisted by the ergonomic handle and harness, which provides additional stability.

The 2 different trimming heads were of particular interest to us, as they greatly enhance the effectiveness of this commercial weed eater. One of the heads is a grass trimmer spool that is suited for regular weed trimming and detail work along fence edges. The other head is a brush cutter blade that is designed to cut through thicker shrubs.

Another feature we liked about this option is the wide safety guard, which protects the user from deflected dirt and debris. The detachable telescoping shaft deserves also special mention, as it makes the unit easy to store and reassemble.

What Could’ve Been Better?

While the string trimmer spool is easy enough to reload, the same cannot be said for the brush cutter blade. Replacing it is a fairly complex task, which many users may find annoying. Besides, finding the correct replacement blade can be a challenge as well.

Pros
  • Can handle any weed-trimming task
  • Easy to store and assemble
  • Offers good stability when in use
  • Prevents debris from splashing around and making a mess
Cons
  • The brush cutter blade is difficult to replace

5. Ryobi Gas Trimmer

Here, we have reviewed the RY34426 gas trimmer by the brand Ryobi. If you are a seasoned DIYer, you will have heard about this brand and its wide range of reliable power tools. The RY34426 is one such product, which is known for its lightweight design and powerful engine.

Why Did We Like It?

Arguably the biggest highlight of this gas weed wacker is its curved shaft design, which makes it easier to handle than conventional trimmers that have straight shafts. This is especially true for shorter individuals, who will find the curved design to be much more maneuverable than a straight shaft.

The unit comes with a 30cc engine that outputs enough power to handle most weed-trimming tasks with ease. In this regard, we need to mention the fuel efficiency and low emissions of this engine, which is one of the best among all gas-powered weed eaters. Because of this, it is a very sustainable option to go for.

What’s more, the fuel tank of this unit has been designed in a manner that makes it easy to monitor fuel usage. Also, the trimmer head is compatible with a wide range of attachments, which provides a good degree of versatility.

What Could’ve Been Better?

The startup mechanism could have been better since it is not as quick as other similar weed eaters. So, you might need to pull on the cord a few times to get it running, which can get annoying if you are in a hurry.

Pros
  • Low emission engine
  • Easy to handle
  • Versatile trimmer head
  • Easy to monitor fuel usage
Cons
  • The startup is difficult

6. Huyosen Weed Eater

Huyosen is a new entrant in the domain of household power tools. However, the brand shows great promise since most of its products have high quality and durability. The same can be said about the Huyosen weed eater as well, which comes with a highly fuel-efficient engine.

  • Safety Design: The debris shield mounted just...

Why Did We Like It?

Thanks to the relatively high-capacity engine, this commercial string trimmer can be used for longer stretches without stalling. The engine consumes very little gas, so it doesn’t need to be refilled as frequently. This gives it an advantage over other string trimmer models. Likewise, the three different trimmer heads make the machine versatile for all types of lawn care activities.

This weed eater comes with an ergonomic U-shaped handle that has a slip-free design. Combined with the convenient shoulder strap and lightweight build, it makes the weed eater extremely convenient to carry around. The starting system is also quite effective, as it allows you to get it running within a short time.

We liked the safety features of this particular unit too. It comes with a safety shield that protects you from debris and a valve throttle protection switch that protects the user against accidental starts.

What Could’ve Been Better?

Due to its advanced 3-in-1 design, it may feel a bit complicated to use, especially for inexperienced users. The user manual doesn’t help much either, as it doesn’t come with detailed instructions for usage. So, you will need to consult third-party guides, which may or may not be reliable.

Pros
  • Doesn’t need to be refilled frequently
  • Easy to carry around
  • Startup is quick
  • Comes with decent safety features
Cons
  • Not that easy to operate

7. Troy-Bilt Gas String Trimmer

Troy-Bilt is a brand that specializes in making all sorts of lawn care and gardening tools. So, including the TB304S on our list was an obvious choice. This gas string trimmer comes with a simple straight shaft design that allows it to reach even the toughest corners on your lawn.

  • 30cc, 4-cycle engine is cleaner and produces less...
  • 4-cycle advantage – Never mix gas & oil!

Why Did We Like It?

The TB304S comes with a clean and efficient engine that reduces noise and vibrations while maximizing output. Combined with the wide 17-inch cutting swath, it enables you to clear large areas of weed in a short time.

Its startup mechanism is based on the unique SpringAssist technology, which allows for easier pull starts. Apart from that, it features a multi-position adjustable handle and shoulder straps, which improve stability and make it convenient to use.

The trimmer comes with the high-capacity Click ‘N Trim bump head, which has been designed to make wire reloading easier. It is also compatible with the TrimmerPlus attachment system. This means that you can swap out the string trimmer head with other attachments, which ultimately improves the versatility of the tool.

What Could’ve Been Better?

When using this straight shaft string trimmer, we noticed that its engine started to become hot after extended usage. Because of that, we were forced to use it in short intervals. This is a significant drawback of this product, as it limits its overall effectiveness for commercial use.

Pros
  • Allows for quick weed removal
  • Easy to start
  • Highly convenient to handle
  • Versatile trimmer head
Cons
  • The engine becomes hot after constant usage

Commercial Weed Eater Buying Guide

And that was our list of the top 7 commercial weed eaters. By now, we are hoping that you have gone through all of them, so have you come to a decision about which one to get? Of course not! 

Buying the best commercial string trimmer for your lawn is not at all an easy task, believe us. After all, it is a relatively complex power tool, and you need to consider different technical aspects to make the correct decision. 

But if you are not so savvy in these matters, you will easily get confused. As a result, you may end up buying a product that will not meet your requirements. 

That is why we have made this concise buying guide so that you do not make a decision that you will come to regret. It covers some of the most important aspects that need to be kept in mind when buying a commercial-grade weed eater. So, if you are curious, then keep reading. 

1. Type

When it comes to weed eaters, the first thing that you need to check is their type. By type, we are referring to the source of their power. In that context, there are two types of weed eaters available today – electric and gas-powered. 

Electric weed eaters can be further classified into two subtypes – corded and battery-powered. To use a corded electric weed eater, you need to plug it into a power outlet. While it doesn’t need to be refueled or recharged, the wires can be a major hassle. That is why it is not a very practical option for a commercial trimmer. 

The battery-powered options are slightly better in this regard since there are no wires to worry about. And with a good enough battery life, you won’t need to recharge it frequently, which further improves convenience. But the problem arises with the price since a good battery-powered model can be very expensive to purchase. 

That is why most users prefer gas models for commercial weed eaters since they do not have such shortcomings. There are no cords to worry about, and you can get high-capacity gas trimmers for a reasonable price. 

2. Engine Size

If you want to make the most out of your string trimmer, then the engine size is an important factor to consider. It is generally measured in cubic centimeters (cc) and denotes the maximum amount of gasoline that the engine can hold. 

Commercial gas-powered weed eaters come in a wide range of engine sizes. You should preferably go for one that has a higher cc, which will allow you to use the tool for long intervals without refilling. But be advised – larger engine sizes usually increase the overall size of the string trimmer as well, which can make it a bit inconvenient to operate. 

3. Cutting Swath

The cutting swath or the line length denotes the width or path of the trimmer string. In simple terms, it is the area that can be covered by the string trimmer at once. Normally, the cutting swath diameter is measured in inches, and it covers the entire span of the string that extends from the trimmer head. 

A larger cutting swath will naturally clear out a bigger area of weeds than a small cutting swath. Likewise, it will be able to reach the tougher spots on your lawn. But on the flip side, a wider swath increases the air resistance, which, in turn, reduces the spinning speed of the trimmer head. Although, this limitation can be addressed if the engine of the trimmer is powerful enough. 

There is a wide variety of cutting widths available for string trimmers, ranging from 7 inches to as large as 24 inches. The smaller widths have incredibly high speeds, which improves the efficiency of cutting. But for commercial-grade weed eaters that come with fairly powerful engines, we would recommend going with a moderate to large cutting swath. That way, you can cover a larger ground and save time. 

4. Shaft Design

Typically, most weed eaters come in two shaft designs – straight and curved. A straight shaft is sturdier and has a better reach overall. However, they are comparatively heavier, which can make them a bit difficult to carry around. In contrast, curved shaft trimmers are much more lightweight and ergonomic to handle. But they do not have the reach of a straight trimmer, which is a major downside. 

For commercial-grade weed eaters, the straight shaft design is more common, thanks to its durability. However, there are certain brands, such as Ryobi, which manufacture good-quality curved string trimmers. So, you can go for whichever one you think will be the most beneficial for your needs. 

If you need further assistance, you can check out our guide on the Ryobi vs. Craftsman 4-cycle weed eater. Both of these are considered to be one of the best curved and straight trimmers, respectively. 

5. Comfort

Weed-trimming activities can be pretty exhaustive, which makes user comfort an important factor to consider. The comfort level of a string trimmer is primarily dependent on the grip and the harness. 

If a trimmer has a soft and ergonomic grip on its handles, it will be comfortable to hold. Similarly, if it contains an adjustable harness, you can wear it on your shoulders, which will help with balance and weight distribution, making it comfortable to use. 

Apart from that, certain other features impact comfort levels, such as the presence of adjustable handles and the design of the trimmer shaft. So, make sure to check them out before you make the purchase. 

6. Ease Of Use

To get the best value out of your weed eater, you should ensure that it is easy to use. This is especially true if you are a beginner since it will allow you to figure out the machine quickly. For instance, if you don’t know how to string a weed eater or replace the line feed, the presence of detailed instructions in the user manual may help you out. 

Besides usage instructions, this aspect can be further enhanced by the presence of different convenience features. For example, if your trimmer has an automatic line feed, you can use it without interruptions. Or, if it has a translucent fuel tank, you can easily monitor gas usage. Therefore, it is important that you check out these features before making a purchase. 

7. Price

The price is obviously one of the most important aspects to consider when buying a commercial weed eater. After all, you wouldn’t want to break the bank by buying a gardening tool, right? 

It is always a good idea to stay within your budget to avoid financial problems. This means that unless you have the necessary funds, you should refrain from buying a trimmer at an exorbitant price, no matter how convenient its features may seem. 

But it doesn’t mean that you should settle for an extremely cheap product either. If you see an option that comes with an unbelievably low price, you should stay away from it because it is more than likely to have quality issues.

Top Commercial 4 Cycle Weed Eater Verdict

That brings us to the end of this informative review-based guide. We hope that you found the information we provided here to be useful in making a decision. 

Before we wrap it up, we would like to mention our personal favorites from the list above. The Husqvarna is our top pick overall, thanks to its well-rounded performance and convenience. 

If you want a larger and more powerful engine, you can go with the Black+Decker , which is our second favorite option. However, if you want a more affordable choice, then we would recommend the Craftsman Weedwacker

With that out of the way, it’s time for us to say goodbye. Until next time, folks!
