The foundation that makes a string trimmer a distinct yet effective lawn care equipment is the string. The string, which is also known as line, is a special type of monofilament nylon that spins at an incredibly high speed to cut and trim weeds and grass in a yard.
The line, however, gets worn out while doing the job. This is why, a string trimmer has a spool of line that is fed to the cutting head as it operates. This is done with the help of the trimmer’s feed system.
What is a feed system?
In simple terms, a feed system is the mechanism that releases the string into the head. Since the string is made of a synthetic or composite material, it is prone to getting worn out from cutting down grass in a lawn. For this reason, a feed system is installed in string trimmers to effortlessly reload the string instead of manually pulling it whilst doing the job.
Types of Feed System
There are currently two types of feed system for best gars string trimmers in the market: bump feed system and automatic feed system. Both of which have distinct advantages and disadvantages. Let’s take a closer look at each type to understand them better.
Bump Feed System
The bump feed system is most commonly used on older models of string trimmers. The method requires you to literally bump the head of the trimmer on the ground to release more string. This type of feed system gives you more control over the length of the line to feed the head.
Automatic Feed System
An automatic feed system is an advancing mechanism that self-regulates string release whenever it starts to run short. Majority of string trimmers with an automatic feed also have an internal sensor component that gauges the length of the line. This type of system takes advantage of the centrifugal force from the spinning to automatically release a new line.
Advantages of Automatic Feed String Trimmers
Automatic feed string trimmers are now the most popularly used type of trimmer in the industry. This is because these nifty equipment have a lot of advantageous perks in comparison to bump feed string trimmers.
- Best choice for beginners
Automatic feed string trimmers are a more user-friendly type of trimmer. They are the ideal choice for people who are relatively new to the lawn care industry since they require less thought and effort.
- Hassle-free feed system
An automatic feed string trimmer automatically feeds string to the head when it starts to run short. Because you won’t have to constantly mind the string in your cutting head, you will have more chance to focus on the task at hand.
In addition to that, an automatic feed system is less likely to break because you won’t need to frequently bump it onto the ground.
- Saves time during job operations
Automatic feed string trimmers allow you to finish trimming faster because the string advances on its own. This means that you will not need to pause from time to time just to feed string into the cutting head.
How Does an Automatic Feed String Trimmer Work?
Automatic Feed System
The automatic feed mechanism works with an advanced internal component. This component gauges the length of the line in the cutting head. Once it has assessed that the line is about to run out, the automatic feed system is activated to automatically feed a new line into the cutting head, taking advantage of the centrifugal force from the equipment’s fast spinning motion to release and pull the line from the spool.
Automatic Feed String Trimmer
An automatic feed string trimmer is pretty much operated like other types of string trimmers in the industry, but with the exception of the feed system, of course. Unlike other trimmers, automatic feed string trimmers effortlessly and automatically release the string into the cutting head. There will be no need to bump it on the ground or manually pull the string out. Rest assured, this type of feed system does not compromise the effectivity and quality of the equipment. In any case, it is even considered as an upgrade from older string trimmers that make use of a bump feed system.
Trimmer Line Replacement

This is because the operator has less control over the feed. In these cases, knowledge about the proper way to wind a new line to the spool.
Below is a step-by-step guide on how to wind a new line to the spool, including some tips and extra precautions in executing the task.

Tips about Line Trimmer Replacement
