Choosing The Best Weed Eater String

Before we jump into my list of the best weed eater string, let us take a look at some of the important properties of a good design’s trimmer line.

Trimmer Line Cutting Efficiency 

Trimmer lines are commonly used for cutting grasses, weeds, and light brushes. I’m sure you already know it is the actual cutting part of a power trimmer. So surely you need to spend some money on it right. Otherwise, it’s like buying a Ferrari and putting cheap tires on it. 

The type of trimmer line you use in your yard trimmer will have a significant impact on its cutting efficiency, what it can cut through and its durability for certain uses.

You also have to use the correct trimmer line for the type of trimmer you have because most trimmer heads and trimmers were designed to accept a given range of line sizes or styles.

Additionally, the nature of the grass or weeds growing in your yard will determine the kind of line you use. For example, a tougher and thicker garden material such as thick weeds will require a heavier and sharper style of trimmer line. 

Round Cords 

Round cords are common and come in different sizes. They give you value for your money, are easy to refill, and are also long-lasting.

If your lawn has more grass than weeds, a cylindrical string might be your best choice. It wears weeds instead of cutting them because of its smooth and rounded edges making it impossible to cut the weeds clean. Additionally, you have to err on the side of caution when trimming near concrete edges or fences. Lastly, round cords are prone to weld together and overheat. On the upside they are cheap. 

Twisted Line 

Unlike the round cords, the twisted line gives you a cleaner cut than a round cord. It can also last long when used around hard surfaces. It produces less noise and vibration thanks to reduced air resistance. The twisted line can be an excellent choice in residential areas when used with either a cordless trimmer or electric trimmer when noise is a concern. 

Square Trimmer Line 

The Square trimmer line has four sharp edges known to slice through weeds quickly and efficiently. It is effective against tall, heavy, and thick lines of weed. Compared to the round cords, the square trimmer offers more cutting power. 

Some major drawback of the square trimmer is that it does not work well around fences or hard surfaces and may even break in the process. It also tends to knock grass out of place when used on light grass and this makes cutting exhausting. Another frustrating issue is that it often wraps around grass which gets the string hooked in the grass. So you will have to pull the trimmer up from the ground each time it happens.

Lastly, it tends to jam easily more than the round lines if you load it incorrectly. 

X-Shaped Line 

The X-shaped line is a durable line that is effective against stubborn and hard weeds. X-Line cuts grass as well as small saplings – you can hear and feel the string tearing into the weeds. Also, it doesn’t fuse together in the spool as others do.

It features a unique shape and so provides you with a clean cut in your yard. It is flexible and does not weld under intense temperatures.

5- Or 6-Sided Line 

The 5- or 6-sided line is available in a variety of sizes; it does not wrap around tall grass or weeds and also cut more easily. As you can imagine it’s a slightly more complex line to extrude during manufacture so it’s more expensive. 

6-Bladed Line 

The 6-bladed line is a professional grade line featuring a ribbed design to work effectively against the hardest cutting jobs.

What Trimmer Line Diameter To Use 

To get it right with a trimmer line, you have to take into consideration its diameter. A thicker line would normally last longer, but it will take a huge bite out of your wallet. So, before you consider what diameter to settle on, determine your budget and of course what diameter line your trimmer can handle.

Most domestic level weed eaters will take up to 0.085” line, and usually more expensive or larger model swill accept larger sizes right through to .155”. Just be sure to know what your trimmer will accept. If in doubt go with the .085-.095” line.

A good rule of thumb when using a string trimmer line is to use a thicker line on a tougher application. A big diameter increases the durability and power of the line – leading to less wear-out and breakage.

.065 – .080 

The .065 – .085-inch line is best used for less dense areas, and light trimming of weeds and grass.

.085 – .095 

The .085 – to .095 trimmer line works best with thicker grassy areas and heavy grasses.

.105 – .155 

This is more durable and is best for long-duration trimming with a thick brush.

Material & Strength 

To choose a line on the criteria of material and strength, you have to determine the duration of usage and how often you are willing to work. If you are setting out for light trimming, a softer line should be used. However, you should use a stronger line if you are out for full-scale work.

The material of the line, its shape, the contact surface (e.g. rocks, fences, curbs, etc.), and the condition of the yard (thick or less dense) will determine the strength of the trimmer line.

The round trimmer line is used mostly by professional landscapers because of its optimal grade of durability. It is made up of more material with a reduced surface area which is one of the reasons for its prolonged usage without wearing out. It is designed using reinforced nylon or non-nylon polymer. Reinforced nylon is typically more resistant to tearing and breaking. So, higher quality material will normally give a stronger line.

Furthermore, non-polymers and copolymers are also used to design trimmer lines for increased strength.

Spool Length 

A longer and heavier trimmer line is necessary for trimming stubborn and dense vegetation in an environment with nettles, weeds, and long grass to prevent the line from breaking.

Whereas, areas such as edges of lawns, less dense grass, and flower beds will require shorter and lighter spool lengths.
