Walk Behind String Trimmer Buying Guide

Looking for the best Walk Behind String Trimmer is a difficult job indeed, especially because of the number of features that it has. Moreover, it is also very hard to distinguish between a lawnmower, a string trimmer, and a walk-behind string trimmer. Therefore, we bring you a detailed guide on the most important features that make a walk-behind string trimmer great.


Suffice to say, engines are the most important part of a walk-behind string trimmer when it comes to performance. An average trimmer houses a four-stroke engine powerful enough to handle any overgrown shrubbery in your lawn or backyard. However, these engines produce a lot of waste; therefore, you need regular oil changes and hard maintenance to keep them running smoothly. Moreover, as the name suggests, each trimmer has a string that acts as a starter rope that starts the engine very quickly; you can also call this a recoil starter since it has a quick start system faster than any lawnmowers in the market.

Power Source

The most common walk behind string trimmers is electrical; however, the more powerful ones run on gas. Electric trimmers are much easier to start, and they produce less noise and vibration than gas trimmers. Moreover, they are also easier to maintain since they produce less waste than gas trimmers. Furthermore, electric trimmers also do not produce toxic emissions that are harmful to the environment.

You also have to note that electric walk-behind string trimmers are of two types, and they are either corded or cordless. Cordless trimmers have batteries as a power source, while corded ones run on electricity.

On the other hand, gas-powered trimmers are much more powerful and are excellent for places with large growth and shrubbery. They offer longer runtimes but at the cost of slower start times and toxic gas emissions. Moreover, you also have to maintain it better than electric trimmers.


The most important part of a walk-behind string trimmer when it comes to mobility is the wheels. While the weight plays an important part, it is the wheels' quality that determines how easy it is to move your trimmer around your lawn. You need a large wheel with a solid foundation to move through the overgrown shrubbery and greens without suffering long-term damage. Moreover, those which are 16 inches or larger are easy to move around even on uneven grounds.

Cutting Area

The cutting area or the cutting swath in the front of a trimmer contains blades that work through the shrubbery. Walk-behind string trimmers use a string system instead of cutting through weeds and grass, compared to typical lawnmowers. Therefore, the main difference between a normal lawnmower and our trimmer is the cutting width; and a string trimmer has a significantly larger cutting area than a normal lawnmower. The largest trimmers can even go above 22-inches in cutting width. These are perfect for large lawns and are excellent for drastically reducing work time.

Some walk behind string trimmers even uses up to four string in the cutting area for better efficiency and cutting accuracy. Moreover, having strings as a cutting tool means that you also can adjust your cutting height to what you want. Therefore, these are perfect for multiple types of lawn and terrain.

Replacement Line

No matter how powerful and durable a walk-behind string trimmer is, the one place that it always deteriorates is the replacement line. Since string trimmers handle tough bushes and shrubbery, the line breaks quite often. There is no fault within the machine itself, and this is a maintenance issue in all walk-behind string trimmers in the market. Therefore, when you purchase a trimmer for your lawn, you should buy a few replacement lines beforehand so that you be ready for it. The best thing about replacement lines is that you get them in all lengths and sizes; moreover, these are also quite affordable.

Handle Grip

Every walk behind string trimmer features an angled rectangular handle that extends towards you. This is an important part of a trimmer since you use the handle to maneuver the machine. Moreover, the handle grip needs friction to prevent slips. Also, it needs to be comfortable so that you can hold it for a long period. A typical gas walk behind string trimmer generates a lot of vibration that makes it comfortable to hold the machine for a long period. Therefore, you should look for trimmers that feature an anti-vibration mechanism that reduces vibration; thus, reducing the strain it puts on your hands. Moreover, try looking for trimmers that have handle foam or rubber to have a better grip.


The most common place to store a walk-behind string trimmer is your garage. Even though a trimmer is quite big, storing it is not a problem since you can fold down the handle to its body, reducing the trimmer's size by a lot. Therefore, storing it in your garage takes minimum space.

Pollution Levels

Gas walk behind string trimmers produces a lot of toxic emissions that are harmful to the environment. Moreover, they require a lot of maintenance, and you need to change the oil quite a lot. If pollution is a big concern to you, then try going for an electric trimmer since they produce almost zero emissions. However, you will have to sacrifice a bit of performance in the process since gas trimmers are always more powerful. However, you will only need more time to complete tasks with an electric walk-behind string trimmer when working the same lawn. An electric trimmer does a fine job of handling an overgrown lawn, even though it takes more time. However, since it cuts down pollution to almost zero, the price is worth it.

Price and Warranty

Walk-behind string trimmers are expensive machines, and therefore, budget is an important thing to consider when purchasing one. A typical but excellent trimmer like the Southland SWFT15022 can cost you around three to four hundred bucks, whereas the premium ones like the EARTHQUAKE 28463 can even reach eight hundred bucks. While there are trimmers below two hundred, these see a significant performance drop both in power and work speed. However, if you are willing to sacrifice time due to a short budget, trimmers like the Southland SOWST4317 will do you justice.

Since trimmers are expensive, it is important to find one that has a good warranty period. While it is rare to find trimmers that offer a lifetime warranty, ones with a two to five years period are not hard to find. EARTHQUAKE offers the best warranty periods while Southland offers an average of two years.
