For instance, a person mainly doing weekly lawn maintenance should get a different string trimmer than someone clearing heavy brush or overgrown grass. The same is true if you are a homeowner… how much land do you have? What are you trimming? How often? These are all great questions to take into consideration.

Buying Guide

Below is a buying guide to help you choose the best commercial weed eater for your specific needs.

Engine Size

Engine sizes are determined by cubic centimeters, better known as cc's. There are two different types of engines that determine cc. One is a two-stroke engine, and the other is a four-stroke engine. The sizes of a commercial weed eater engine range from 24 to 31cc. The bigger the engine, the more power it has.

Engine Type – 4-cycle VS 2-cycle

There are significant differences between two and four-cycle engines. The biggest difference is the fuel. Two cycles run on a ratio of gas and oil mixture. Four cycles run on straight gasoline. They also have a special place for the oil to go, and it needs changing like any engine with an oil drain plug. 

Two cycles have the oil and gas mixture, so there is no need to have a place for motor oil. The four-cycle engines are also bigger, and some, but not all, weigh more than a two-cycle. The preference is in the user's opinion. Four cycles may have more power as the engines are bigger. 

Cutting Swath

The distance in cutting range measured in inches is the cutting swath. In other words, as you swing the string trimmer, the length of the shaft will determine the distance. Most straight shafts will have a cutting swath of 20 to 24 inches. So naturally, the longer the cutting swath, the more grass gets cut.

Shaft Type – Straight vs. Curved

There is a saying once you use both and go to the straight shaft, there is no going back. The straight shaft is so much easier on the back muscles. A curved shaft does not have the outreach a straight shaft does. Using a straight shaft allows a natural flow for both the arms and back. Those who use a curved shaft have to keep their back arched and arms bent, which can cause fatigue.


The weight of commercial weed eaters ranges between 9 and 14 pounds. Some four cycles can weigh as much as 15 to 18 pounds. It is important to keep in mind not all four cycles are heavy. Some are known to weigh 10 or 11 pounds, depending on the materials of the weed eater.


Comfort is critical when using a commercial weed eater. Those who use a commercial weed eater daily know how important it is to have a comfortable string trimmer. These are the areas to look into what features make the weed eater comfortable.

  • The grip on the front and rear handles
  • The strap, if it is cushioned or not. 
  • If the throttle has a cruise control
  • If the handles are adjustable
  • If the strap is adjustable
  • A straight or curved shaft makes all the difference in comfort.


Commercial weed eaters are very durable and can take a lot of beating. Looking into the parts of the string trimmer can determine the durability. In other words, what material makes up the equipment. Make sure the parts are not able to rust or get corroded. Some features are made of plastic. If that is the case, check to make sure they are not going to break. 

Most commercial weed eaters will go on a rack with an open trailer. Make sure the weed eater can withstand the outdoor climates. As far as cutting, make sure there is enough horsepower to handle tough jobs. Look into the cc for this. 

Fuel Capacity 

Make sure to get a weed eater with a decent-sized gas tank to hold a fair amount of fuel. The average would be 20oz or more. Keep in mind the capacity does not entirely rely on how long before running out of fuel. Efficiency determines in the end how long the fuel in the tank will last before running out. 

However, a small tank is not a good idea when in the commercial business. The last thing you want is to get caught running out of fuel when a long distance away from the gas can.

Fuel Efficiency

Several factors determine fuel efficiency. They are as follows.

  • Engine size
  • Type of fuel 
  • If the fuel has a stabilizer in the mix
  • If the weed eater is adequately cared for and maintained
  • Age of the weed eater


Most of the brands offer a two-year warranty for commercial use on commercial weed eaters. Some will go three to five years if the same string trimmer is used for homeowners. At the time of purchase, the question will come up. If purchased for a lawn or landscaping business, it will automatically fall under the commercial warranty. However, the homeowner warranty will take effect if it is listed under a person's name. Should the warranty be listed under the person's name and the signs show the weed eater was used in commercial business, the warranty may be voided.

Single Purpose or Multi-tool String Trimmers?

The single-purpose string is used for regular trimmer cutting. It is only used for grass and weeds. The string will eat up pretty fast and is not the best for commercial use. Multi-tool string trimmers are used for different purposes and cutting terrains. These are used for thicker weeds and take less time to cut. 

Gas vs. Electric Weed Eater – Which is Better?

It depends on the user and how much is getting trimmed. An electric weed eater is perfect if only for around the house and a few trees. It is also cheaper. The gas weed eater is more efficient for commercial purposes and long distances. Most gas weed eaters are better when it comes to power, but electric weed eaters are catching up with the latest technology. 

What is the Best Commercial String Trimmer on the Market?

A survey was taken with over 1,000 landscapers. Echo commercial string trimmers turned out to be the best on the market. 

The Best Weed Eater Strings For Trimmers

Many will argue whether or not the string you use in your weed eater matters. In short, yes, it does. Certain strings are provided to be better and last longer than others. Below is a list of the best commercial weed eater strings on the market.

Oregon Gatorline

This string has a high cutting efficiency. It allows for straighter, cleaner cuts with little to no effort. There is a high-strength inner core within the string to make it more durable than the rest. It comes in the round trimmer line with a .095 diameter, which is the most effective and longer-lasting than any other shape. Lastly, it fits all trimmer models. 

Husqvarna Titanium Force

Edgit Pro

Interested in turning your weed eater into an edger? Of course, many lawn care companies will use string trimmers to edge lawns… we've all done it at some point. However, this probably isn't the best idea if you want a quality and consistent edge every time.

A solution to this is the Edgit Pro (make sure you choose your correct trimmer model.) I used these for 3 years in my company, and they save a ton of time. Basically, you only have to go to the truck once to trim and edge instead of twice. If you are doing a lot of residential properties, this is a huge time saver.

If you decide to use the Edgit Pro, make sure you have a way of carrying extra string with you. Since you are edging with your trimmer a lot more, you will naturally go through the trimmer string a little bit quicker.

Wrapping it up

Hopefully, this guide clarifies which ones are the best weed eater options for you and your commercial business. Everyone knows the best way is to save time as it can make you more money if you have the best commercial weed eater. Along with the buyer's guide and the list of the best strings, you can deliver the best cut yards for your customers.

  1. Shindaiwa 262 and Echo 2620 are basically the same trimmer. Echo bought Shindaiwa.
    With you on the Husqvarna 525LS. It’s basically a unicorn in these parts. Walbro carbs + solid steel shaft + power to weight ratio.
    Another Unicorn, which I’ve found, is MARUYAMA. If you list Makita, you should list Maruyama.
    IMO, the Stihl FS94R (straight 2 cycle) is superior to the FS91.
    Echo black diamond line is generally regarded as superior to their cross fire line.
    Letting the battery powered products get a little older before making a decision. The Echo SpeedFeed head is the best, currently. When someone can show me THAT head on a battery powered unit (outside Echo-whose batts aren’t very highly rated currently-again, hurry up and wait), I’m sold. Too early yet. When you go batt, you go full in/all in on a single line (Ego, etc).
