How to Choose the Best Trimmer Line?
The truth is, the right trimmer line is different from one person to the next. The best line is the one that meets your specific needs and is compatible with the trimmer owned.
So you have to determine your needs: will you be trimming light, medium, or heavy-duty grass and weed cover? Are you just using this product for your home or are you using it for commercial purposes?
You have to consider your needs and then choose a trimmer with the shape, material, diameter size, and lengths that best meets your needs.
Trimmer Line Shape
Trimmer lines with this shape are your standard lines that are good for your day to day yard work. It is a great choice for homeowners who work in their own yards. It is the most common type of line and the easiest to replace.
Trimmer lines with this shape are best suited for larger yards, thicker weeds, and landscaping. With multiple sides, these lines are sharper and will deliver sharper cuts than round lines.
The sides usually make patterns such as square, star, or pentagon. You may also find them referred to by the number of sides they have, for example, “6-bladed trimmer line”.
Unfortunately, their shape is not ideal when they hit a hard surface as they tend to break easier than round ones.
Trimmer lines of this nature feature multiple lines that have been twisted into a solid shape.
Twisted lines are stronger and will provide more efficient cutting, allowing to save time and effort. They are ideal for thicker weeds and are most often used in professional scenarios.
They produce less noise and vibrations making them easier on the hands and ears. A twisted line is an improvement over a round trimmer line and will be able to take impact from hard surfaces such as concrete.
These lines have edges that behave like teeth. As such they are ideal for use when you have stronger, thicker overgrown weeds and more grass to get through.
They are ideal for commercial purposes as they will allow the user to cover more ground in less time, although for a higher price. Serrated lines usually come in a pre-cut line format.
Trimmer Line Diameter
The trimmer line diameter you choose is based on the type of greenery you will be cutting. There are three rough categories for line size. Bear in mind that each trimmer can only handle specific line diameters, it is best to check this in the weed eater user’s manual.
Specific trimmer line diameter reviews:
0.60 – 0.80 inches: Light-medium work
This category includes finer lines that are suitable for light work, such as residential lawns and light weeds. They are ideal for homeowners with smaller yards and less vegetation. Typical use is in lightweight weed eaters.
0.085 – 0.105 inches: Medium-heavy work
This category includes lines that are suitable for medium-heavy work. These are ideal for larger yards with more grass and heavier weed cover. They are also ideal for light commercial work.
0.110 inches and over: Heavy work
This category of trimmer line is typically for professional use. They are great for large yards, large estates, industrial landscaping, golf courses, and large gardens that require extensive grass and weed trimming. Very popular size for most walk behind string trimmers.
Trimmer Line Length
A string trimmer line most often comes in spools, although there are pre-cut options as well.
Each spool has a different length so pay attention to the amount of line you will be getting for the money.
Professional lawn service companies eat away hundreds of feet of strings on a regular basis, but homeowners may not need a lot.
The length you choose depends on how much work you will be doing. It also depends on how hard your trimmer will be working, whether there are hard surfaces, fences or trees where the trimmer line can break.
Check your trimmers manual to see how much length of line you need for one refill and then decide which length is right for your needs.
Durability and Materials
The durability of the line depends on the shape and the diameter of the line as discussed above, just as well as on the materials used to manufacture the line.
Cheaper lines tend to be made from simple plastic and may break easily. Another common material used to make trimmer lines is nylon. Nylon allows more affordable pricing and it is also more durable than plastic lines.
Other advanced materials and technologies include:
- Co-polymer Nylon: The best trimmer lines based on the material would be the ones made from co-polymer nylon. This material provides the best durability but tends to be more expensive.
- Strengthened Nylon: Some manufacturers offer nylon lines with strengthening materials such as aluminum. This improves durability but is also more difficult to manufacture.
- Reinforced Internally: Other nylon lines are reinforced internally to prevent them from breaking off easily.
Compatibility – Will it Fit?
The first you want to do is to check the manual of your string trimmer before you make a purchase. Each weed eater head is designed to only feed lines of a certain size or up to a certain size. Trying to put in any other size will just cause frustration and will be a waste of money.
You will find a number of replacement strings on the market that are described as “universal”. This means they can fit any tool, regardless of the brand. If you are purchasing one of these options it is still best to check for compatibility with your tool prior to purchase.
How to Install a Trimmer Line
How you install a trimmer line depends on whether it is a pre-cut line or a spool.
Pre-cut Trimmer Line – These are already sized so you can pull out and wind up lines quickly. The downside to this option is that you may have to refill your trimmer more often. Mistakes will also lead to some wasted lines.
Spooled Trimmer Line – These allow you to fill a long length of wire. The installation is easy with automatic or bump feeders with a pop in and pop out mechanism.
Regardless, here is our guide on how to string a weed eater properly.
