Types of Trimmer Line

There are several types of trimmer line available on the market. Each type of trimmer line has its own set of pros and cons. In this article, we will discuss the most popular types of trimmer line and help you decide which one is right for you.


Monofilament is a single strand of synthetic material, usually nylon. It’s inexpensive, durable and easy to find. Most manufacturers include monofilament line with their trimmers. While it’s not the best line for all trimming applications, it will work for most people most of the time.

The biggest advantage to monofilament is that it’s relatively inexpensive and easy to find. You can buy it just about anywhere trimmers are sold, and it comes in a variety of thicknesses (or diameters) to match your trimmer. Monofilament is also quite durable, so it will last a long time before needing to be replaced.

There are a few downsides to monofilament, however. First, it tends to wear down quickly when used on tough obstacles like concrete, stone or metal. Second, monofiliment can be more difficult to feed through the trimmer head than other types of line. And finally, monofiliment doesn’t always hold up well in hot weather – it can become brittle and break easily when exposed to too much sun or heat.


Multifilament trimmer line is made of 2 or more strands of nylon that are fused or braided together. The advantage of this type of trimmer line is that it’s very strong, so it doesn’t snap as easily as monofilament. It’s also less likely to fray.

The main disadvantage of multifilament trimmer line is that it’s not as durable as monofilament, so it needs to be replaced more often. It also tends to be more expensive.


Braided line is made of multiple strands of nylon, Kevlar or other synthetic fibers that are woven together to form a single, stronger line. The number of strands and the materials used determine the strength and durability of the line. Most braided lines are round, but some brands make square or flat braided lines that are designed to cut through thick weeds and grass more easily.

How to Release Trimmer Line

In order to release the trimmer line on your trimmer, you will need to first locate the release button. The release button is usually located on the top or side of the trimmer. Once you have located the release button, you will need to press and hold it down while you pull on the trimmer line.


The spool on a trimmer houses the trimmer line. Typically, the spool is located in the head of the trimmer. In order to release more trimmer line, you need to first remove the spool from the head of the trimmer. Once you have done this, you can then proceed to release more trimmer line as needed.

Bump Feed

Bump feed trimmers release line automatically when you bump the head of the trimmer on the ground. This is the most common type of trimmer, and most models have a bump feed feature. Many people prefer this type because it is easy to use and usually does not require much maintenance.

To release line on a bump feed trimmer, start by removing the spool cap from the head of the trimmer. Then, pull out about 6 inches (15 cm) of line and cut it with a pair of scissors. Next, reattach the spool cap and lightly tap the head of the trimmer on the ground. This should cause the line to advance. If it does not, double check that the spool cap is on correctly and try again.

Automatic Feed

With an automatic feed, you’ll never have to stop and bump the trimmer head to release more line. These trimmers have a spool that automatically feeds new line as needed. This can be a great time saver, but it’s important to know how to properly use an automatic feed trimmer. Follow these steps and you’ll be sure to get the most out of your trimmer.

How to Change Trimmer Line

Unwind the spool of trimmer line until the end of the line is exposed. Cut the trimmer line at a 90-degree angle using a pair of scissors. Insert the end of the trimmer line into the holes on the spool. Wrap the trimmer line around the spool in a clockwise direction.


The type of trimmer you have will largely dictate how you go about changing the trimmer line. We have found that most gas-powered trimmers and all electric trimmers have a spool on the underside of the trimmer head that you can access without having to remove the head. If your trimmer has this type of spool, follow these steps to change the line:

1. Unplug the trimmer or remove the spark plug (for gas-powered trimmers).
2. Press down on the spool release button and turn the spool counterclockwise to release it from the trimmer head.
3. Pull out the old line from the spool, being careful not to unwind it more than necessary so you don’t get tangled up in it. If there is residual line stuck in the head, you can use a pair of needle-nose pliers to pull it out.
4. Feed new line through the eyelet on the underside of the spool until there is about 6 inches hanging out.
5. Wind the new line around the spool in a clockwise direction, making sure not to overlap or crisscross the line as you wind. You should wind it snugly but not too tightly — you should be able to press down on it with your finger without too much resistance.
6. Once you’ve reached the end of the new line, cut it with scissors and tuck any excess into one of the empty slots on the side of the spool (if your spool has them).
7. Reattach the spool to the trimmer head and press down firmly until you hear it click into place — if your model has a locking mechanism, engage it now. If necessary, feed a bit of new line through
the eyelet until it sticks out about 6 inches from under
the head, then proceed to step 8.

Bump Feed

This method is perhaps the most common among trimmer users. The general process involves pressing a button orknob on the trimmer while the trimmer head is in contact with the ground. This causes the trimmer line to advance through the head. Some models may allow you to lock the button or knob in the engaged position, while others may require that you hold it down for as long as you need more line.

Automatic Feed

Automatic feed trimmers have a spool of line that is automatically fed out as needed. These trimmers are easy to use, but the line does need to be repaired or replaced from time to time. Automatic feed trimmers use cutting line that is 0.065 inches in diameter and is made of nylon monofilament. The cutting line is strung on the trimmer in a specific way so that it can be fed out evenly as needed.
