1. Black+Decker String Trimmer – Best for Heavy-Duty Weeding

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.

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.

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

2. Troy-Bilt Gas String Trimmer – Best for Versatility

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.

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.

Buying Guide For The Best Commercial Weed Eater

And that was our list of the top 2 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. 


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. 

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. 

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. 

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. 


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. 

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. 


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.
