How Does A String Trimmer Work

String trimmers are an essential tool for anyone looking to keep their garden tidy. They work by cutting the grass on a long, staggered line, which prevents the clippings from piling up and becoming a fire hazard. In this article, we’ll take a look at how a string trimmer works, from the basics of its engine to the different parts that make it work.

How a String Trimmer Works

A string trimmer is a type of power equipment used to trim grass, weeds, and other vegetation. The machine has two main components: the head and the engine.


The head consists of a motor and a number of rotating blades. It is attached to the engine, which powers the blades. When you press the trigger, the engine sends power to the head, which starts spinning the blades. This action cuts the vegetation.


The engine powers the head and also provides power to the trimmer’s accessories, such as the blade guards and line feed spools. It can also recharge your battery.

The Types of Strings on a String Trimmer

A string trimmer is a type of hedge trimmer that uses a blade to cut through tall grass, weeds, and other vegetation. In order to use a string trimmer effectively, it is important to know the types of strings on a trimmer.


The three most common types of strings on a trimmer are nylon, polypropylene, and polyester. Nylon is the cheapest and weakest of the three strings, but it holds its shape well and can last for several years without becoming worn or frayed. Polypropylene is a middle-of-the-road option that is both strong and durable, but it can sometimes stretch out or become brittle over time. Polyester is the most expensive option, but it also lasts longest and has the best resistance to wear and tear.


It is also important to remember to replace the strings on a string trimmer periodically in order to keep them in good condition. Over time, the strings can become torn or damaged, which will make it difficult to trim your hedges properly. By replacing the strings on your trimmer regularly, you can ensure that your hedge looks its best and stays healthy throughout the year.
