Factors to Consider Before Purchasing the Best 155 Trimmer Line

Initially, the best 155 trimmer lines usually look the same, but they may have different colors and packaging and also differ with several features. Therefore, when choosing the best 155 trimmer line, there are factors you should consider, including:

1. Trimmer line Material

The 155 trimmer line models usually come in different materials, with the basic light-duty trimmer line made out of plastic and nylon materials and the heavy-duty trimming line made of a combination of aluminum, nylon, and synthetic polymers. The most popular material is the copolymer nylon because it offers durability and the most expensive material is titanium which is new in the market.

2. The diameter

The diameter trimmer line is one of the most important factors to consider, as the diameter of a 155 trimmer line affects the ability to cut through certain weeds. Light diameters usually range from 0.065 inches to 0.080 inches, medium diameters from 0.085 to 0.105 inches, and heavy diameters usually measure from 0.110 inches and beyond. Opt for a small diameter trimmer line if you will be using your string trimmer to handle light yard work.

3. Shape

The shape of the trimmer or a weed eater usually determines how well your trimmer works in terms of the durability of the string, noise level, vibration level, power of the equipment, and cleanness of the cut. The various shapes include:

a). Round Shape

This shape of trimmer string is available in all sizes and is durable, economical, and quite easy to reload. The round trimming lines are suitable for lawns that plenty of grass and minimum weeds as it does not work well on weedy areas since the smooth edges usually tear through weeds instead of cutting them clean. This shape cannot withstand large materials and will wear down quickly when used in such circumstances, but it breaks less and is suitable for everyday use.

b). Square Trimmer line

This square shape has four edges that easily slice through tough weeds and highly bush and offers plenty of power even though it’s more likely to break when it encounters hard surfaces. It’s a suitable option for maintaining weedy areas or overgrown bushes and spaces and residential and commercial use.

c). 6 Bladed Line

The six-blade shape design or the multi-sided line is more of a professional-grade trimmer line, and it comes with a ribbed design that holds up even in the hardest cutting jobs for professional landscapers.

The multi-sided lines are ideal for medium-sized lawns or yards with thick grass or heavy weeds because they have sharp edges that cut through weeds and give off a clean look. However, this trimmer line shape usually breaks easier than the round shapes making it less ideal for navigating the areas with plenty of obstacles to work around. It is ideal for commercial trimming.

d). Serrated String

The serrated shapes usually have a flat profile with teeth on the narrow edges, and they provide aggressive cutting power for bushy areas and tough weeds. This shape of 155 trimmer lines is suitable for large spaces, but it is not the most suitable shape for a clean-cut residential look.

e). Twisted Shape

The twisted shapes in trimmer lines usually give a cleaner look than round strings when cutting thick weeds and give off more durability when the 155 trimmer lines are working on hard areas. The twisted trimmer line works best because it reduces air resistance, enabling the string trimmer to work with minimum noise levels and vibration of the string trimmer head. The twisted line makes suitable options for people looking for quiet string trimmer models and better when combined with cordless or electric trimmers.

f). Spiral Shape Design

This trimmer shape design is more common in battery or electric-powered string trimmers because it is quiet. The spiral shape also makes a good cutting tool for landscaping professionals because of the noise reduction and won’t have anyone complaining about loud noise. Additionally, the spiral design is suitable for heavy foliage and helps any line cutter create clean cuts.

4. Durability

How quickly your trimmer line breaks down is how fast you will need to replace it, and you should opt for the maximum durability since the more trimmer lines you buy is, the more money you are spending. A durable string will help you get more work done per spool, and the durability varies depending on the shape, type of material, what you are trimming, and how much friction the string trimmer is encountering.

Opt for the round string to get the best durability because it’s made of reinforced nylon or non-nylon polymer. Some have hardened core material that offers more durability than basic nylon.

5. Length

Trimmer lines usually come in spools, and the length of the string trimmer line is important because you will get the maximum value for your money and save you several trips to the store. Even though getting larger lines in terms of length at an affordable price is easy, you should choose a high-quality line that will not finish as fast as the cheap quality.

6. Cutting Efficiency

The cutting efficiency is determined by factors like the trimmer line shape, where the most efficient shapes for cutting thick weeds are the serrated or twisted trimmer lines. These two provide efficient trimming for heavy-duty tasks and in cases of thicker grass or thicker weeds. Also, in general, to get the best cutting ability from your 155 trimmer line, you should ensure you purchase a high-quality trimming line.
