Without a doubt, weed eaters are useful gardening tools that any household should have to keep their yard looking beautiful and neat. However, these practical tools cannot function properly without being equipped with a correct trimmer line.

Keep in mind that not all trimmer size will do - the thinner the line, the more it will struggle in pushing heavier brushes.

Thus, larger lines work perfectly when trimming heavy weeds as they are sturdier, thicker, and don't break easily.

With a wide range of options, the last thing that you'll have in mind is to end up with a faulty line. The use of a .155 trimmer line is the right choice, especially when doing massive works such as trimming large grassy areas and taming thin woody brushes.

For this reason, we've listed and reviewed the best .155 trimmer line to help you get the most of your money.

.155 Trimmer Line: The Buying Guide

1. What is a Trimmer Line?

.155 inch trimmer line

The use of a string trimmer or weed eater is a must to keep your lawn beautifully and adequately maintained. This ideal tool uses a string instead of a blade to cut grass, allowing you to reach even the problematic areas with ease and comfort.

The trimmer line is an essential mechanism of a weed eater, as it is responsible for cutting through weeds and grasses. This long material, similar to a string, is inserted to the tool to allow cutting through your yard.

Depending on the trimmer design, you can choose whether to use a pre-cut trimmer line or a spooled trimmer line. 

  • Pre-cut Trimmer Line
    The pre-cut trimmer system comes in individual lengths of line. This allows simple and quick changing of the line. However, you will also find yourself stopping more frequently due to gauge errors.
  • Spooled Trimmer Line
    The most common trimmer lines are available in a spooled system wrapped around the trimmer head. Even though reloading this line can be a bit tricky, this design makes reloading a lot easier and faster.

2. Picking the Best Trimmer Line

Before purchasing a product, be sure to consider these essential factors and qualities about trimmer lines. 

  • Material
    Most trimmer lines are manufactured using nylon and copolymer materials. These synthetic materials are hard enough to work well and cut almost all types of weeds.
    Titanium-made trimmer lines are also good options as they are extremely useful even for long runs. However, this material is a more expensive option.
  • Shape
    The perfect shape is necessary for choosing a trimmer line as it determines the power, vibration, and sound of the equipment. However, the shape will depend greatly on the model of your weed eater.
    The five significant trimmer shapes lines available in the market include spiral shape, square design, rounded shape, bladed shape, and twisted lines.
  • Size
    The thickness and diameter size of the trimmer line will determine the kind of work that it will produce. The large-diameter lines are for tough tasks, while the smaller diameter lines are for trimming thinner weeds.
    Larger trimmer lines, such as .155, are designed mainly for large-scale landscaping and heavy-duty works. 
  • Features
    Some additional features should be considered when it comes to picking your trimmer lines. Look for a line that can reduce the sound produced, especially if you are living in a residential area where noise is not welcome.
    Weather factors should also be kept in mind. Picking a trimmer line that works perfectly even on snow is a good choice if you are living in a snowy area.

.155 Trimming Line FAQs

What Determines the Life of My .155 Trimmer Line?

The durability of the trimmer line usually boils down to the quality of the material used in making the line. The best material is the titanium-made ones.

However, it is far from being budget-friendly. As an alternative, the copolymer nylon is a specially designed material that can also handle extra-resistant torture.

What is the Primary Consideration of Trimming Lines?

With the variety of trimming lines available, the main factor that you should consider is the compatibility of your string diameter on your machine.

Also, be sure to know the type of device you are using, whether electric, gas-powered or battery-operated, to determine which trimmer line works perfectly.

How to Find the Correct Trimmer Line Diameter?
