Why do I Need a Weed Eater String?

If you want to keep your lawns neat and clean, a string trimmer is an awesome pick.

You can use it to mow hard-to-access spots, cut thick grass, and weeds that a mower can’t (sidewalks, trees, fences, flower beds, etc.), clear thick brushes, and make perfect edge lines for an amazing-looking garden.

In a way, a trimmer is the finishing tool that will deal with the areas which you missed with a mower.

String trimmers can be powered by batteries, electricity, or gas using a whirling line (string) instead of a blade. This string protrudes from a rotating wheel at the end of the shaft that’s topped by the motor.

The line has to swirl fast enough to become rigid enough. This rigidness can cut weeds, plants, and grass.

Which Factors to Consider Before Buying?

In order to find a suitable string for your trimmer, you need to check the manual or the website of the manufacturer to learn the recommended sizes.

When you learn this info, make sure you also consider other 5 pivotal features, i.e. durability, material, shape, line size, and resistance to weld.

Let’s learn a bit more about each and why they’re important!

Durability

Durability can be seen when the string is used with heavy weeds and harder surfaces. When the string is made more durable, you can finish more per spool.

The durability of a string for trimmers depends on the materials it’s constructed of, as well as its shape, the material you’re trimming, and the friction against the surface, i.e. concrete, stone, etc.

Given it has the same material and shape, the thicker the string is, the longer its durability will be.

To be sure you’re making a good choice; you can never go wrong with a round string. This one has more material and less surface area which prolongs its wear time.

For example, a round string with a reinforced non-nylon polymer or nylon or with a hardened core material is more durable than basic nylon.

Material

The basic strings for trimmers are usually made using hardened monofilament nylon.

This has been long the standard in the industry; however, there are always efforts being made to better the durability. Although plain nylon lines are still used and are effective, much stronger materials are also available.

They’re better in terms of their efficiency and will help you increase the cutting power. For example, reinforced composite nylon-its resistance to breakage is very high.

You can also find strings with added materials for strength like aluminum or non-nylon polymers.

Shape

Generally speaking, there are three different trimmer string shapes, i.e.round, twisted, and multi-sided. The shape also influences the performance of the string, including how clean the cut will be, how long the string will last, and the level of noise produced.

Considering all of these important aspects, it’s essential to match the shape with the conditions you’ll be using it with.

  • Round

These strings are available in all sizes.

They’re praised for their durability, economy, and ease of reloading. It’s the best option for lawns that are mostly grass and only a couple of weeds here and there.

Avoid them for properties high in weeds as the smoother edges can tear through them instead of cutting them cleanly.

This string also tends to overheat and weld together when you’re cutting near fences or concrete.

  • Twisted

This type of string offers a cleaner cut than that of round ones when the weeds are thicker. And, it’s stronger around harder surfaces.

It has reduced air resistance which helps it work with lower noise and vibrations than other shapes of strings.

  • Multisided

If you plan on using the trimmer with heavy weeds and thick grass, choose a multisided string. Its sharp edges easily cut through weeds and help you achieve a cleaner look.

However, it tends to break easier than the round ones if you overuse it around hard surfaces, so it’s not the most suitable option for locations with a lot of obstacles around.

Line Size

You can find out more about the durability of the string through its line diameter. A thicker line usually lasts longer, but it’s also costlier.

This is why you need to consider the conditions in which you’ll be cutting, the number of times you want to reload, and the money you’ll spend on the line thickness.

And, don’t forget-not all sizes are suitable for all trimmers, so read the directions of the manufacturer first.

For illustration, a light-duty trimmer string of .065 to .085-inch diameter can be used with small and medium gardens with only a few weeds.

Those between .085 and .11-inch diameter would be more suitable for larger areas where the grass and weeds are also thicker.

If there are also a lot of fences, edges, and woody plants, opt for the heavy-duty ones (higher than .110-inch diameter).

Resistance to Weld

Welding happens when the string overheats and sticks onto the spool. This is a result of high speed operation while cutting along some surfaces like a concrete wall or a fence for a longer period.

This friction leads to heat collection that further makes the string softer and then sticky with each other. And, it won’t feed out of the spool so we have to manually remove it and restring the spool.

Of course, most materials used to make these strings are made weld-resistant to a certain extent, some higher, others lower.

Round strings have the least surface and thus, heat builds up faster than in other shapes.

How to Use a String Trimmer?

  • Put on PPE

Protecting your eyes while working with a trimmer is pivotal since even a tiny piece of debris traveling at 200; 300 mph can severely injure your eyes.

  • Avoid shorts and sandals

Did you know that even the broken off pieces of the trimmer line can cut skin? Therefore, avoid wearing shorts and sandals and exposing your skin.

And, when you’re cutting, angle the trimmer so that the cut stuff goes away from you, not into you.

  • Don’t forget the cables

Make sure you’re not hitting the cable if you’re using an electric trimmer.

Although the line won’t cut the cord, it may damage the insulation, causing further problems.

  • Avoid having bystanders

Debris may easily reach a person who’s near you.

Make sure everyone is at a safe distance before you proceed.

  • Properly start it

Although you should follow the instructions because each trimmer works differently, generally speaking, it’s based on the method with 2-stroke engines.

Turn on the ignition switch and then the choke.

Prime its engine by pushing the primer button around 8 times. Pull the cord repeatedly until the engine starts working. Leave it to run around 10 seconds before you turn off the choke.

  • Cut with the bare tip

When you’re cutting grass or weed, do it with the bare tip of the line as this is the part that moves at the highest speed.

  • Care for the line

Always avoid slapping the line into the grass, but rather ease it into the vegetation. Otherwise, the trimmer will lose momentum and the cuts won’t be optimal.

When should I Replace it?

If the string has broken down while trimming around a hard surface or if you’re not cutting properly, it’s best to replace it.

Never guess the size or type, but check the manufacturer’s website or consult the customer service department.

Do it only when the engine is turned off and cooled down.

You remove the cap from the head, depending on the mechanism. Now, you find the starter hole in the spool and insert the tip of the string and wind it into the arrows’ direction.

You wrap it in straight and neat rows. If there’s surplus string remaining, you can cut it. Then you reattach the cap back on.

How to Clean my String Trimmer?

No matter the type of trimmer (electric, battery-powered, etc.), it’s always important to remove grass and debris after use with cloth or gloves.

On the gas ones, ensure the gas level is always optimal, and don’t forget to recharge the batteries on battery-powered models.
