Trimmer Line Buying Guide

How Trimmer Line Works

The Trimmer line uses monofilament lines in cutting weeds, grass, and woody plants. By rotating at a higher speed, the cutting head becomes more capable of generating sufficient centrifugal force that keeps the lines at a rigid horizontal angle, making effective and convenient cutting possible.

The user or operator can manually adjust the arc and height of the trimmer. These kind of adjustments makes the trimmer more useful in cutting around trees, rock beds, and more. Also, this can be turned vertically-edges contours near sidewalks and driveways.

On many models, the lines and cutting heads can be changed to accommodate different line gauges. But you'd better check and find out what your cutting head can handle. However, this still depends on the type of jobs performed.

You can use thicker pre-cut lines, thinner tail lines, square and jagged lines, and even chains or blades. Cutting lines come in a variety of thicknesses and shapes and are made in various materials.

The Meaning Of The Thickness Of Trimmer Lines

It's no surprise to anyone; however, as a general rule of thumb when it comes to thread trimmer lines, the more complex the work being done or the application, the thicker the lines can be. A larger diameter tends to increase the lines' durability and power, leading to minimal wear and tear.

For lighter jobs such as trimming grass, 0.065"-0.085" would be sufficient. For thicker weeds and grass, a line range of 0.085"-0.110" can do the job without problems. For weeds, anything thicker than 0.110" is enough to work with and get the job done.

Why does my trimmer line keep breaking?

A big reason for this is that you are using the wrong line. If you are experiencing many lines and these lines keep breaking, you may be using the wrong size. Some people get thicker lines because they think such a line can cut off thicker growth. If you also think of

That way, well, you'd better think again. This will only put additional loads on the motor, and as a result, the line will move slower.

Perfect trimming should be carried out at full speed. Keep in mind that the tip of the line makes the cut and not the middle down. Therefore, keep most of the line out of this, so it doesn't wear or break, and you will undoubtedly end up with a cleaner, faster cut.

Why My trimmer line breaks or wears out quickly

It's normal for lines to wear out, but with trimmer lines, this wears out faster than you expect if you're cutting thick, tough grass and weeds, cutting against hard surfaces like walls and rocks, or if the line usually spins too fast.

To preserve the cutting line when you are cutting thick grass and weeds, or cutting against hard surfaces, avoid crowding the trimmer head to the place you are cutting. It would help if you slid the head slowly toward cutting the area; therefore, use the tip of the cutting line. You could also consider reducing the throttle to properly control the cutting head speed significantly when cutting against complex surfaces.

Old cutting lines can be somewhat fragile and vulnerable to breakage. In case your line is already older than five years and often breaks, it is time to replace it. If you replace your trimmer line, you can try using star-shaped or square lines because they tend to wear out faster than other lines.

Cutting Lines Advance Too Far

Every automatic or bump feed trimmer line comes with a small blade, properly fitted to your guard, preventing the trimmer line from becoming too long. The blade will soon dull and sometimes break. In any circumstance, the line tends to feed longer than expected and will probably cut into fences, shins, trees, and flowerbeds. The good thing is that it is easy to replace broken or dull cutting blades.

Is Thicker Trimming Line Better?

Is a thicker trimmer line better? Keep in mind that the trimmer line comes in different thicknesses. For light work, such as trimming grass and weeds, you should opt for 0.065"-0.085". For grass and weeds that look thicker, it would be better to have a 0.085"-0.110" line. Anything thicker than 0.110" will work for thicker weeds.

Is Twisted Trimmer Line Better?

The Twisted Trimmer line is best for heavy, heavy use in yards loaded with grass and thick, heavy weeds. The Twisted Trimmer line is known for improving efficiency, adding strength, and reducing noise levels. This line is established from a round style line and provides durability when hitting hard and concrete surfaces.
