12 Best Commercial Weed Eaters – Heavy Duty Weed Wackers

If you’ve got a lawn or garden to maintain just like me, your arsenal is probably already stacked with different types of tools including bulky gas-powered machines and a few quiet battery products. 

So, should you add another bulky tool – a weed eater to the mix? While most weed eaters are lightweight, sleek machines that come with an ergonomic handle, 2-stroke engine, or rechargeable battery, a commercial weed eater is generally used by a landscaping professional and just as you might’ve guessed is a much more powerful tool than a household weed eater. 

Commercial weed eaters with superior quality blades for trimming grass and other areas can be expensive tools for even a professional landscaper compared to a weed eater for personal use. 

There are two main reasons for choosing a commercial weed eater:

1. If you have a sprawling yard and garden and/or
2. If you need a battery or gas string trimmer for your landscaping business. 

When shopping for the best commercial weed eater, you will be spoilt for choice given the sea of options available.

But I’ve done the research and rounded off on the 12 best commercial weed eaters available that include models with a 4-stroke engine, an electric trimmer, and a cordless trimmer edger.

I’ve also included a detailed commercial powerful string trimmer guide to help you choose the right model for your needs. 

In a rush? These are the ones I recommend. But keep reading if you want more info on each.

What I Looked for When Choosing the Best Commercial Weed Eater?

I’ve selected the 12 products on this list based on three key factors – power, noise output, usability and durability. 

Power

Since we’re talking about commercial-grade weed eaters, it’s only right that I tackle the topic of power first before anything else. 

Gas weed eaters with a 2-stroke engine or 4-stroke engine are typically regarded as being more powerful than their battery-powered counterparts. 

However, newly launched electric and cordless weed eaters like the models mentioned on this list offer excellent power and are in fact a preferred choice for a commercial landscaper. 

Gas weed trimmers are rated by engine displacement, ranging from 30cc to 50cc+, cordless weed eaters by voltage, from 18V to 85V+, and electric corded trimmers in amps, typically from 2A to 10A. 

If you have a larger yard, choose a battery or gas weed trimmer that offers a longer runtime, be it with larger batteries (preferably 2) or a larger fuel tank. 

Some battery-powered models come with blades instead of a tough nylon string for enough cutting power for cutting down thick, heavy brush. 

I haven’t added any electric (corded) weed eaters to this list of best commercial weed eaters because most models I tested didn’t provide a commercial-type feel and experience. Plus, their power cord limited their usefulness. 

Noise Output 

After using both gas and cordless commercial weed eaters, what I can tell you firsthand is that gas-powered models are quieter than cordless models. 

Either way, both types are loud enough to wake up your neighbors in the wee hours of the morning, so it’s best not to use them at that time and use ear protection any time when using a commercial weed eater, regardless of the type. 

Usability 

There are a few weed eater models that are easy to use and come with features such as an automatic feed system or no bump feed head, which feeds the line to the trimmer head usually with the push of a button. 

Further, it’s also important to check how easy it is to replace the string or blade on the respective weed trimmer model. 

Durability 

Commercial weed eaters should showcase a tough build and plow through stubborn weeds and grass without any issues. They should also come with components made from high-quality materials such as a solid steel drive shaft, a premium type of engine, cast aluminum housing, good quality spark plugs, etc. 

Commercial Weed Eater Buying Guide 

There are several things to consider when on the shopping trail for the best commercial weed eater, most notably:

Curved Shaft or Stright Solid Steel Shaft 

Weed eaters can come with one of two types of shafts – a curved or a straight shaft. Choosing between the two types largely depends on personal choice, but curved shafts tend to be shorter, and allow you to easily maneuver around obstacles, while straight shafts increase your reach and coverage from a particular point. 

The Right Power Source 

Commercial weed eaters can be powered by gasoline, a battery, or a power cord, and all are capable of cutting well, depending on the model. If you have a large yard gasoline weed eaters are a good option, but for yards that measure a 1⁄4 acre or 1⁄2 acre, I’d choose a corded string trimmer and cordless string trimmer respectively. 

String Trimmers vs. Bladed Trimmers 

Perhaps the only difference between string trimmers and blade trimmers is that the former use a monofilament line typically made from types of nylon, and the latter use a blade that can be made from either plastic or metal for the trimming task. 

Many people believe that blades tend to last longer but this isn’t always true because good quality nylon lines do indeed do a better job and last longer than poor quality plastic or metal blades. 

Additionally, if the plastic or metal blades hit against concrete or stone often, they may chip and break entirely, leaving you with no other option than to replace them with new ones. 

Feed Systems 

Commercial weed eaters can come with 2 predominant types of feed systems, which are mechanisms that control the amount of string fed out through the trimmer head. 

1. The traditional system is called a bump feed, and entails pressing down on the guard in a bumping motion to manually release more of the line. One of the benefits of a bump feed is that it gives you more control over how much line you use as long as you know what you’re doing. 
2. The second type of feed system is called an automatic feed system, which basically progresses the feed line automatically as you go. 

This means that you don’t have to do anything special to continue trimming, but on the downside, you don’t get the same level of control, and can be difficult to fix if they break. 

Cutting Width 

Commercial weed eaters usually come with a cutting width between 12 inches to 14 inches on average. This number refers to the coverage of cutting grass or trimming weeds without you having to move the tool at all. 

Therefore, the higher the number, the more ground you can cover and the less effort you have to put into the task. However, larger cutting widths aren’t always a good choice for all types of yards and don’t determine how effective a commercial weed eater actually is, because smaller cutting widths are great for smaller yards. 

Trimmer and Edger Combo 

Some of the models on this list allow you to perform two totally different garden tasks with a single tool:

• Trimming and
• Edging. 

To explain briefly, trimming is cutting in areas where a mower can’t reach, and edging puts a fine line between the grass and borders or sidewalks. 

Do you need both tools?

Well, it depends on whether you just want to quickly remove unwanted weeds, grasses, and other plants that grow around fences, mailboxes trees and shrubs and/or want to create distinct edges. 

If you’re going to perform both tasks, you’re better off buying a trimmer and edger combo as it will save you some cash and space in storing two tools. 

Vibration Control 

Certain weed eater models come with an anti-vibration system to reduce arm fatigue – a feature that’s especially good to have with gas models. 

Weight and Size 

Most, if not all the products mentioned on this list are fairly lightweight, so they won’t bog you down during use, especially when using the tool for longer periods of time. 

Some models may be heavier than others owing to the extra features they come with such as a bevel gear, larger engine size like a 28cc 2-cycle engine, and/or a solid steel drive shaft. 

Safety Features 

Safety should always be a top priority with any tool you use, and the good news is that a majority of the best commercial weed eaters implement the latest safety features during use. You may have to buy safety gear such as gloves and eyewear if your weed eaters didn’t come with them. 

Final Thoughts 

Buying a commercial weed trimmer even for residential use is a good option, especially if you have stubborn weeds to deal with. 

The 12 models on this list are some of the best commercial weed eaters available, and won’t let you down in terms of performance and durability.
