Best 155 trimmer line Buying Guide

Any landscaper or gardener can use any trimming line in the market but it is important to check some features in those trimming lines.

1. The shape

The vibration power and sound from trimming equipment are determined by the shape of its trimming line. The market has four major shapes and they include the twisted shaped (spiralled), round shape, bladed shapes (serrated) and multi-sided shapes. The shape of your trimmer line will depend majorly on the type of weed eater you own.

2. The diameter sizes

The size of the diameter determines the type of trimming work to be done. For the large scale landscape, the diameter is mostly .155inches. The tougher the work, the larger the diameter required while the smaller the weeds, the smaller the diameter lines needed. The large diameters increase the power of the lines and the durability resulting in a low possibility of breakage and minimal wear out.

3. The trimmer line material

The materials normally manufactured are mainly Titanium, Nylon, and Copolymer. Copolymer and nylon are the most used materials that work well together in cutting different types of weeds. Titanium is the most expensive material and new in the market.

Additional features to consider

1.    The sound it produces especially if it’s for use in residential spaces where noise can be an issue.

2.    Trimmer lines that also work well in the snow are a feature to consider especially if you live in a location that snows.
