How to Buy the Best Trimmer Line

While every part of a string trimmer has an essential role to play, the trimmer line is by far the most important given that it is what will do the actual cutting. Hence, you cannot afford to buy the wrong one. But, to make sure this will never be the case, you only need to consider the following factors when shopping.

1. Compatibility

The first thing to consider when buying a trimmer line should be compatibility because everything else will not matter if you cannot use the line on your weed whacker model.

Most manufacturers will clearly state the kind of trimmer line that their products use and the style and dimensions. Also, if you have been using the string trimmer line for some time, you should have some idea on the line it uses.

Also, trimmer line manufacturers will clearly indicate the string trimmer types and models that their lines are meant for, and so taking some time to read the description will ensure you end up with a compatible line.

2. Style

Once you have figured out the compatibility part, you will then also need to decide on the string trimmer line style to go for. And here you will need to choose between 5 common styles which are multi-sided, round, twisted, square and serrated.

Multi-Sided

The multi-sided trimmer lines are the kinds that will feature an angular construction and will come in various shapes such as pentagon, star, and square. When compared to others like the round style lines, the angular shape gives these trimmer lines a sharper edge for a cleaner cut.

Multi-sided trimmer lines are great when dealing with thicker weeds, and also when you have a larger yard to work on which should explain why they are the preferred option for commercial use.

Round

If you are on the market for the best trimmer line for edging, the round-style trimmer lines should be one of your top considerations as they excel when it comes to trimming grass edges.

These trimmer lines are also great for everyday residential care as they are one of the cheapest styles available. However, these lines also wear out quite fast and might not be able to withstand heavy trimming applications.

Twisted

Twisted trimmer lines are another perfect choice for commercial trimming applications. These lines also excel when it comes to clearing lawns and yards that have thicker and heavier weeds.

What makes them great for commercial or professional application is that the twisted design makes it hard for the line to break even when you hit hard surfaces like trees or concrete. And the twisted design will also enhance their efficiency and minimize noise.

Square

Square style trimmer lines are also multi-sided which makes them great for cutting down denser and thicker weeds as they have sharper edges.

These lines are bigger and thicker than most other types, and this ensures they can cut any weeds in their path more easily. They will not weld when you accidentally hit hard surfaces which makes them great for landscaping.

Serrated

As the name suggests, the serrated trimmer lines will have edges all around the line which will act as teeth for trimming. With this serrated design, these trimmer lines are able to cut tough weeds with ease.

The serration makes these trimmer lines great for commercial applications where the trimmer will be faced with more weeds as they can cover larger areas within a shorter time. These trimmer lines can saw through any kind of yard grass or weed and will hence be perfect for heavy-duty use.

3. Diameter

As you choose a trimmer line, you will also need to consider the diameter as they come in various diameters. And the right line diameter for you will depend on the task at hand. The larger the weeds or the tougher the materials you intend to cut the larger the line diameter you should use.

If you are buying trimmer line for use on residential lawns that typically have light weeds, a light duty line with a diameter of 0.065 to 0.080 inches will be ideal, and it is also more affordable.

For medium work such as trimming larger residential lawns or working on yards with heavier and thicker weeds, a medium duty line with a diameter of 0.085 to 0.105 inches will be perfect.

For those shopping for a trimmer line for gigantic yards infested with super thick weeds or want something for industrial landscaping, a larger diameter line will be perfect. Larger diameter lines that are over 0.110 inches in diameter will also be more ideal for professional landscapers.

With the best 0.155 trimmer lines, there is no trimming task that will be too tough for you as these thicker diameter lines can handle almost anything.

4. Material

The material used to make the trimmer line also matters as it will affect both its cutting efficiency and durability. And you will in many instances need to choose between nylon and titanium when it comes to trimmer line materials.

Nylon Lines – Nylon trimmer lines are the most common options and many users prefer them as they are relatively more affordable. They are quite flexible which ensures they do not snap easily, and if you get them in the right shape and diameter they will be ideal for almost any situation.

Titanium Lines – Titanium trimmer lines are a relatively new entrant into the market, and are hence not as commonly available as the nylon lines. However, the harder material means they will provide better cutting power than nylon lines. And while these lines work well for heavy-duty tasks, they are also pricier than the nylon lines.

5. Durability

Any trimmer line that you buy should last long enough to ensure you do not have to keep replacing it which can be time-consuming and expensive.

There are several things that will determine durability, but the key ones are the material used to make the line and how it is made. Typically, titanium lines are more durable than nylon ones, but some manufacturers will also use a more hardened nylon material to make their lines more durable.

Reading customer reviews on a particular trimmer line before buying it and also buying from reputable brands like DeWalt, Oregon and Grass Gator is a good way to ensure you end up with durable trimmer lines.

How to Install a Trimmer Line

Buying the best string trimmer line is just the first step in ensuring quick, easy and efficient trimming as you will also need to ensure you install it correctly.

While the installation will depend on the line style you have and also your trimmer head type, it is still quite straightforward, and here are the general steps you will need to follow.

Step 1: Remove Spool

Start by switching off the trimmer and disconnecting it from the power source to ensure you can work safely. Once the weed whacker is turned off, you can proceed to remove the spool by locating and pushing the release button. But note that different trimmers will use different mechanisms to retain the spool, and so to know how to release it you might need to refer to the manual.

Step 2: Empty Out Old Line

Once the spool is out of the trimmer, the next step is to empty out the old line as there will always be some line left and in most instances, it will be damaged and unusable.

Step 3: Install New Trimmer Line

The third step and most important of them all is to insert your new line. And here you should start by preparing the new line which entails cutting it to the right length which for most trimmers is 9-foot long. For double line trimmers, you will need two 9-foot long lines.

You should then wind the lines on the spool following the arrows that are drawn to indicate the winding direction. Make sure you wind the entire line until about 6-inches is remaining which you should then press into the retention slots.

Step 4: Check and Test New Line

The last step is to check whether the new line is installed correctly. And to do this, you will need to switch on the trimmer and see how the line cuts. If there appears to be a snag, you should remove the spool and wind the trimmer line again.

Conclusion

A trimmer liner is a critical component of a string trimmer as you cannot do any trimming without it. But for fast, efficient and clean trimming, you need to choose the best trimmer line from the many options available.

With the right information in mind, choosing the right trimmer line for your weed whacker should not be hard. And in this piece, we showcase the most important things to watch out for when shopping for these handy lawn maintenance accessories.
