The main thing that makes a string trimmer a piece of effective and different garden equipment is its string. Being a unique kind of monofilament nylon, the string rotates at an incredibly high speed, thus cutting and trimming grass in the process. String trimmers are lightweight equipment and offer convenience to users. Apart from being easy to carry, one can easily change the line whenever it gets worn, and the tool can reach areas that a lawnmower can’t.
If you own a string trimmer but don’t know how to work it, this article is for you. Learn about how your string trimmer works here.
Components of a String Trimmer
A string trimmer is made up of many parts. You must get the hang of all these components if you must work the tool. All about each of this string trimmer parts have been explained below.
The motor of a string trimmer is where the power of the whole machine comes from. Without this part, the trimmer cannot generate energy to function. What the motor does is to give power to the spinning rotor. Meanwhile, the rotor is what houses the line, and as such, the line uses this power to cut grass and weed. String trimmer motors come in two types.
Gasoline-powered string trimmers engines, like any other gas engine, runs through simple combustion. This engine has a carburetor and an exhaust. Though it is quite stressful to start a gas engine, this is not the case for a gas-powered string trimmer. It features a pull- rope process that causes the spark plug to fire and start the engine. This kind of generator is powerful, but it makes a lot of noise.

Corded Electric Trimmers
A corded electric trimmer has a cable and is powered by electricity. However, trimmers with this kind of motor are not as reliable as gas-powered ones. These machines cannot use a string that is more than 2.5 diameter because they can only pull 1200 watts of electricity.
However, the electric-powered trimmers are much lighter than gas ones, and as such, they can be moved more quickly. Also, they do not make noise; they’re less expensive and require lesser maintenance compared to gas-powered trimmers.
Battery Powered Trimmer
This is another variant of electric trimmers. However, instead of having a cable that connects to an electrical outlet, this trimmer comes with a battery. This battery is what supplies power to the machine. Because they don’t have a cable, it is easy to maneuver them. The downside of this engine is that the battery tends to run down quickly, thereby limiting the length of time for which the tool can be used.
As a component in a string trimmer, a shaft joins the motor and the spinning rotor together. As the motor spins, the internal mechanism of the shaft, energy gets transferred to the spinning rotor.
It is this part of a trimmer that houses the monofilament string. Once power reaches the shaft from the motor, the power is then transferred to the cutting head. The cutting head then rotates, and this action is what causes the line embedded in it to spin and cut grass. Depending on the particular string trimmer, the cutting head can house either a heavy gage line or a light gage line.
Safety precautions cannot be overemphasized when using a string trimmer. Like other garden tools, a string trimmer can be very dangerous both to you and to the people around except, of course, you learn to handle it with utmost care.
Start by placing a safety guard around the cutting head. The cutting head is the most dangerous part of a trimmer and using a safety guard on it helps you prevent the tool from harming you while trimming. The guard also gives direction to the dirt.
The type of trimmer you choose depends on what kind of job you want to use the equipment for. Because gas-powered engines are more powerful, they can slice off woody bushes and taller grasses. Some gas trimmers have a rotating feature which is ideal for edging. However, gas engines always emit harmful substances and are quite loud. Electric terms, on the other hand, are quite and environment-friendly. But they can are best suited for light jobs. Whichever one you choose, you should be able to operate it now that you know how it works.
