You already have a ton of features to think about when shopping for a string trimmer: curved and straight shafts, gas power or electric power, and more.
But quite possibly the most important option to consider is the part of the trimmer that actually trims: the head. There are different kinds of string trimmer heads, and they can make or break your yard work experience.
You might come across some models where the trimmer head has a trademarked brand name that reflects its new technical innovations. The best example we have is the quick-loading Oregon Gator SpeedLoad Head.
But at the core of the matter, there are only three line-feed designs:
In bump feed systems, varied lengths of line are wound around the spool of the trimmer with two equal lengths fed through openings in the trimmer head.
These systems work by lightly tapping or “bumping” the bottom of the trimmer on the ground while you're trimming. The line advances when the spring system releases the line through the line outlets.
Bump feeds are easy-to-use and dependable, so they tend to be the most popular feed system.
Many trimmers use automatic feed systems. Similar to bump feed systems, auto feed systems use a line-spooling motor, with no effort required while the trimmer is in use.
Fixed head systems use individual lengths of line that are loaded or threaded into the trimmer one at a time as needed. This avoids some of the hassles of winding line onto trimmer heads and makes the overall process of dealing with trimmer line less cumbersome.
A string trimmer is a versatile tool that lets you finish all kinds of lawn care chores quickly and conveniently. With different types of trimmer heads to choose from, it's easy to turn your trimmer into a personalized piece of equipment that works right for you.
