Trimmer Line Buying Guide

How Trimmer Line Works

Trimmer line utilizes monofilament lines in cutting weeds, grass, and woody plants. Through spinning at a higher speed, the cutting head becomes more capable of generating sufficient centrifugal force holding lines out at a stiff horizontal angle, making effective and convenient cutting possible.

The arc and the height of the trimmer can be adjusted manually by the user or the operator. Such adjustment makes the trimmer more useful in terms of cutting around the trees, rock beds, and more. Additionally, this can also be turned vertically-edging outlines near the driveways and sidewalks.

On numerous models, the lines and cutting heads can possibly be switched out in order to accommodate different line gauges. But you better check and figure out what your cutting head can handle gauges. Nevertheless, this still depends on the type of jobs performed.

Thicker precut lines, thinner spooled lines, square and serrated lines, and even chains or blades can be utilized. The trimmer lines came in a variety of thicknesses and shapes and made in different materials.

Trimmer Lines Thickness Meaning

It comes as no surprise to anybody; however, as a rule of thumb when it comes to string trimmer lines, the tougher the job performed or the application, the thicker the lines can be. A larger diameter tends to increase the durability and power of lines, which leads to minimal wear out and breakage.

For lighter works like trimming grass, 0.065″-0.085″ would be sufficient. For thicker weeds and grass, a 0.085″-0.110″ line range can get the job smoothly done. For the underbrush, anything that is thicker than 0.110″ is enough to work and get the job done.

Why Does My Trimmer Line Keep Breaking?

why does my trimmer line keep breaking?

If your trimmer is breaking, it is perhaps due to using the wrong line. If you’re experiencing lots of lines and these lines keep on breaking, you might be utilizing an inappropriate size. Some individuals get thicker lines for the reason that they think that such a line can cut thicker growth. If you also think that way, well, you better think again. This will just put added loads into the motor, and as a result, the line will move slower.

The perfect trimming must be carried out at full speed. Keep in mind that the line’s tip does the cutting and not halfway down. Therefore, keep the most line out of this so it won’t wear down or break, and you will surely end up with a cleaner and quicker cut.

My Trimmer Line Breaks or Wears Down Quickly

It is normal for lines to wear down, but with trimmer lines, this wears faster than what you expect if you are cutting thick and tough grass and weeds, cutting against tough surfaces such as walls and rocks or if the line tends to spin too fast.

In order to preserve the cutting line in the course of cutting thick grass and weeds or cutting against hard surfaces, avoid crowding the head of the trimmer to the spot you are cutting. You must rather slide the head slowly towards cutting the area; therefore, use the tip of the cutting line. You must also consider easing off on the throttle to control the cutting head’s speed properly, particularly when you cut against tough surfaces.

The old cutting lines can somehow be brittle and vulnerable to breaking. In case your line is already over 5 years and often breaks, it’s about time to replace it. In case you end up replacing your trimmer line, you can try utilizing the star-shaped or square lines because these tend to wear quicker than other lines.

Cutting Lines Advance Too Much

Every automatic feed or bump feed trimmer line comes with a small blade, set properly to its guard, preventing the cutting line from getting very long. The blade will soon become dull and breaks off at times. In either circumstance, the line tends to feed out further than expected and probably slicing to fences, shins, trees, and flowerbeds. The good thing is that it is simple to replace broken or dull cutting blades.

Is Thicker Trimmer Line Better?

Is a thicker trimmer line better? You have to note that the trimmer line comes in different thicknesses. For light works, like trimming grass and weeds, you need to opt for 0.065″-0.085”. For grass and weeds that seem thicker, it would be best to have a 0.085″-0.110″ line to get the job done. Anything thicker than 0.110″ will work for the thicker underbrush.

Is Twisted Trimmer Line Better?

is twisted trimmer line stronger?

Twisted Trimmer Line is better for heavy-duty and intense use on yards loaded with thick and heavy grass and weeds. Twisted Trimmer Line is known to improve efficiency, add strength, and reduce noise levels. This particular line is established from a round style line and provides durability when hitting hard and concrete surfaces.
