Trimmer line materials

Trimmer line is most commonly made out of nylon, but many manufacturers vary from this standard to improve a trimmer line’s durability or cutting power.  Heavy duty fishing line might work, but probably will be too thin to whack down much more than the thinnest grass.trimmer line

Basic Trimmer Line

  • Most trimmers operate with an industry-standard cutting line. This line is most often made from a hardened, mono filament nylon line. These cutting lines range in diameter, which tells you how durable the lines are; the thicker the line, the less it will break. However, thicker line will require more engine power to whip the head around at a fast enough speed to cut through the blades of grasses and weeds.

Reinforced Trimmer Line

  • Many trimmer lines are made of reinforced composite nylon materials for extra strength that resists breakage. Trimmer line can be made from non-nylon polymers or other materials for long durability. Sometimes, trimmer manufacturers will mold a small amount of aluminum into the nylon line to reinforce the outer nylon material. Other line manufacturers will use composite nylon materials to reinforce their cutting line. Another option uses a polymer added to the nylon for even more reinforcement.

Trimmer line shapes

Trimmer lines also come in different shapes, but the shapes aren’t just for looks. Trimmer line shapes change how efficiently a trimmer cuts and how it cuts.

Generally, the most common trimmer line shapes are round, twist, square,diamond, star, six-sided lines and so on. Trimmer line with edges tends to cut more strongly than round lines, but it also breaks more frequently against harder surfaces.

  1. Round trimmer line is the most standard type and the most commonly used, which is less resistant to breakage, but it tends to tear grass more than other types because it lacks cutting edges.
  2. Twisted trimmer line is an improvement upon standard round line. The twisted shape gives twisted trimmer line a bit of an edge in comparison to round.Trimmer line shapes that have edges are sharper. The edges that square and 5-point trimmer lines have allow the lines to actually slice through grass and weeds.
  3. Serrated trimmer line has sharp peaks along its edges like a saw or kitchen knife, exposing more cutting surface for extra cutting power.
  4. Multi-sided or edged trimmer line (square, 5-point or 6-point) always leads with a cutting edge to easily cut dense grass and weeds, more edges create more cutting power. It’s best for users to try a few and use what works for them.

It’s important to note that using line that has more cutting power (edges) can sometimes take a trimmer user off guard. The cutting edges can make the line “grab” vegetation a little more than round and twisted line. That grabbing action can actually pull the trimmer down toward the ground, so users should be prepared to offer additional resistance.

 

Trimmer Line Diameter

Trimmer line diameter is pretty straight-forward: the heavier the application, the thicker the diameter. Not only will a larger diameter increase the cutting power of the line, it will also increase its durability against thicker grasses, weeds, and brush. Each trimmer or trimmer head will normally only accept a specific range of line diameters, so it’s best to check the user manual before setting out to buy replacement string for the first time.

There are three main diameter sizes of trimmer lines for different works in your garden, depending on how large of a yard and how thick your weeds are. Before you go and buy a string trimmer line, check your string trimmer to see what it is capable of holding, as most can only go handle a certain size. Refer to the product handbook if you’re unsure. Okay, now let’s get onto the actual lines.

 

Light Work: .065 inches – .080 inches, good for residential front and back lawns with lighter weeds. The small jobs around the house.
Medium Work: .085 inches – 0.105 inches, good for larger back and front lawns or lawns with heavier weeds and light commercial work. It is perfect for your bigger gardens where you have bigger weeds, and is often used for commercial areas as well.
Heavy work: 0.110 inches, good for Industrial landscaping, large estates,large yards, huge gardens, golf courses and other areas that need a large amount of trimming.

 

  • Light-medium work: grass cutting
  • Medium-heavy work: grass and small weeds
  • Heavy work means for grass, small weeds, and large weeds
