What is a trimmer line?

Best .155 Trimmer Line

If you want to keep your lawn properly maintained in an easier and faster manner, you will need a string trimmer, often also called a lawn sweeper or weed eater. A string trimmer uses a string and not a blade to cut grass.

A string trimmer is an ideal tool to reach every area of your yard, especially the difficult-to-reach areas, with ease and convenience. The trimmer line is the most important mechanism of the string trimmer because it is the one that cuts through grass and weeds.

A trimmer line is a long material similar to a string. It is inserted inside the string trimmer so I can cut through and around grass and weed.

The type of trimmer line you need depends on the amount of cutting that needs to be done. Working with the right trimmer line will get your job done quickly and thoroughly.

If you only need to do a little cutting, you will be fine with a thin and simple trimmer line made of nylon material.

If you are to work in a large area or as a professional landscaper, you will need a tougher and thicker trimmer line. For large weeds and grass that need to do a lot of trimming (e.g., huge gardens, large estates, industrial landscape areas), you will require a .155-inch diameter trimmer line.

New string trimmers come with trimmer lines. However, with constant use and over time, these trimmer lines will break, and you will have to insert new ones.

There are many .155-Inch trimmer lines in the market. Here, however, are the top-rated 8 choices.

The next square trimmer line we want to introduce to you comes from Anleolife. Anleolife is not a popular name amongst all the trimmer manufacturers in the USA, but don’t doubt the quality of this product because of that!

Anleolife also made a wise choice of material. They chose the plasticized nylon 66 to create such an affordable yet powerful and damage-resistance product!

Since the Anleolife’s cord is super robust and durable, we’ve been using it for the heaviest tasks in the garden. Thick areas of overgrown weeds are all handled by these cords!

Moreover, these cords are adaptable to many brands and series. The company attaches a bonus line cutter with the cord for convenient cuts. But sadly, we found that this tool is kinda useless, so we just grab a scissor and do the job!

Please tell us if you can figure out how to use it properly!

  • High efficiency
  • Great longevity
  • Adaptable to many types of trimmers
  • Easy to use
  • Useless bonus line cutter

#5. Oregon 22-455 Heavy-Duty Professional Line – Most robust line

  • Brand: Oregon
  • Dimensions: 8 x 8 x 8.75 inches
  • Weight: 15 ounces
  • Best for: heavy-duty strings compared to other trimmer lines

The Oregon Square Magnum Gatorline .155-Inch String Trimmer Line comes with features that make it suitable for heavy-duty and commercial trimming of large areas.

This trimmer line is made from a dual polymer material and aramid fibers. The square shape of this trimming line is responsible for its superb cutting power to cut through thick and big weeds.

The core layer of this Oregon trimmer line is made from high-performing polymer that is resistant to breakage. The outer layer is made from another polymer material that is resistant to abrasion and with anti-welding properties. The aramid fibers reinforce the outer layer for more durability.

A user says that he cut an area full of rock, but amazingly, this trimmer line did not break. He says he knows it will break in time but not as easily as the other brands.

Just like all monofilament trimmer lines, the Oregon Square Magnum Gatorline .155-inch trimmer line can become brittle over time due to loss of moisture, especially when exposed to sunlight and heat.

The manufacturer recommends submerging the trimmer in water for at least 24 hours to bring it back to its normal state.

  • Strong and durable
  • Suitable for heavy duty trimming
  • Square shape provides powerful cutting efficiency
  • Highly affordable
  • Too short at only 84 feet
  • Gray color is not very visible

#6. Arnold 490-030-0034 Xtreme Professional Grade – The best affordable trimmer line

  • Brand: Arnold
  • Dimensions: ‎1.63 x 9 x 8 inches
  • Weight: 12. 8 ounces
  • Best for: lightweight design and durable craftsman strings

Unlike Anleolife or Oregon, Arnold is the name that you must have heard of before if you’ve been a DIY for long enough!

Arnold’s products have been on the market for decades. And during that time, the company has constantly experimented with improving the quality of its gardening tools.

Well, we can claim that if you choose an Arnold model, there’s not much to worry about the quality! About their trimmer lines, especially this 490-030-0034, they are all compatible with many weed-whackers of other major brands.

This maroon 0.155-inch diameter cord is twisted-shaped. The color is not that easy to see, but still better than gray. These cords can cut through thick grass and lawn with ease in a pretty short time. Probably one of the best deals to reduce lawn maintenance time!

However, this twisted shape causes the line to be less durable than an individual sharp-edge string. But considering getting over 100 feet of string at under twenty bucks, it’s still a good deal!

  • Enduring twisted line
  • Strong cut
  • Very affordable
  • The cord might break off

#7. Grass Gator 20155A Trimmer Line – Best for durability

  • Brand: Grass Gator
  • Dimensions: 6 x 6 x 4 inches
  • Weight: 0.01 ounces
  • Best for: quantity of job done for less working hours

As you can tell from the driblet amount of cord in the package, these trimmer lines did not stay with us for too long. After all, it only weighs about 0.32 ounces! We used it up no more than three times.

The best thing about this small package is that homeowners can buy it as a sample to try cutting with cords instead of blades.

But actually, if you do the math between this 20155A’s price and the number of pieces inside, you’ll find that it is not cheap at all!

The lines are made of high-quality copolymers, which are said to have directional aerodynamics tech to improve cutting performance.

We don’t know if it is the lines’ quality that makes them last really long or because we had a limited number of attempts, so we did it carefully! But overall, it works great!

  • Pre-cut lines that save time
  • Pretty durable
  • Great cuts
  • Economical for trial uses
  • A bit expensive for constant use

  • Weight: 3 pounds
  • Best for: trees and branches

The orange color also made it easier to see where you had already trimmed so you could avoid going over the same area twice.
