Best Weed Eater String Reviews

1. Oregon 21-380 gatorline string trimmer line

The weed eater has the ideal thickness for cutting through the grass without being too brittle or stiff.

It’s also quite efficient, as you’ll probably only need 20 feet of line for 1,500 linear feet of property, even if you’re cutting close to concrete.

Another advantage is that it does not make extra noise when cutting, which is a concern with most low-cost trimmer line manufacturers.

This line may not survive as long as it should with current cutting techniques, especially if you nick concrete frequently.

Furthermore, the line is prone to entangling in your weed eater, which can be difficult if you have an auto-feed system.

Buyer’s guide

With an awareness of the most important features of the weed eater line, you’ll be able to get the most out of your trimmer and rapidly turn it into the most valuable item in your shed.

If you’ve always had issues with the dependability and durability of your trimmer line, it might be time to look at the qualities of the best line on the market.

1. Shape

One of the most important things to consider is the shape of your weed trimmer line since it can affect the line’s power and how long it lasts.

There are various distinct shapes to consider, each with its own set of advantages and downsides.


The round line is the most common and will likely come with your weed trimmer; however, it is not the most lasting option.

If you plan to cut through thin grasses, cutting around the line is more than adequate.

However, it is unsuitable for lengthy cutting sessions and will readily break against concrete and fences.


This line is especially popular since it is strong enough to handle thicker weeds and most grass types.

It is also more durable than round, but it is not the most substantial option available.

Another disadvantage of the straight line is that it has the potential to damage certain parts of your land, such as trees and fences.


If you know, you’ll be working with brush, weeds, and ordinary grass, a multi-sided trimmer line will come in handy.

It has significantly higher cutting power but lacks durability since hard surfaces can negatively impact multi-sided designs.


When it pertains to commercial lines, twisted is one of the most common designs; it is the strongest by far and can withstand extreme workloads.

However, it is more pricey than most other types of the line, but the extra expense may be worth it if you know you will be spending lots of time working on your home.

The jagged line is good for working in dense plants and near solid surfaces such as concrete.

2. Diameter

The diameter can also be expressed in thickness, which significantly impacts the line’s aerodynamics and durability.

When cutting through thick vegetation and weeds, the thicker the line, the stronger it will be.

Thinner blades, on the other hand, are better for slashing through the grass.

For most residential projects, you should aim for a line thickness of 0.065 to 0.080 inches.

  • 0.065 through 0.080 is suitable for light work (grasses)
  • 0.085 to 0.105 works well for grasses and non-woody weeds
  • 0.110 and higher is ideal for heavy work, such as thin brush, weeds of any kind, and grass.

3. Material

When it comes to the material of your weed trimmer line, you’ll want to be sure you’re getting a spool made of heavy-duty materials.

These materials must also be lightweight and strong enough to withstand breakage.

The thinner the materials, the more likely you will chew through a massive amount of thick vegetation and weeds.

Major brands use a formula that combines nylon and polymers to provide durability and adaptability.

4. Compatibility

One of the most crucial factors to consider before purchasing a spool of weed trimmer lines is compatibility with various weed trimmer models.

Unfortunately, not all brands are compatible with all tools, as stated on the back of the container or in the product description.

5. Length

To get the best value on the weed trimmer line, ensure you have ample length to last you a full season, whether choosing for a large spool or purchasing more than one spool at a once.

It is critical to weigh the line’s price against the amount, as this might be a good sign of its quality.

For example, if 300 feet of one brand’s line costs the same as 50 feet of another, you may go through the larger spool much faster than the smaller ones.

6. Durability

Consistent use with brush, heavy weeds and hard surfaces reveals the difference in durability. A stronger string allows you to get more work done each spool.

Trimmer string durability varies depending on its material, form, what you’re trimming, and friction with permanent surfaces like stone and concrete. The thicker the string, given the same shape and material, the slower it will wear down.

The round string is the industry standard for maximum durability. It has a longer wear because it combines more material with less surface area. Round string constructed of reinforced nylon or non-nylon polymer, or string with a hardened core substance, will last longer than basic nylon.

7. Resistance to welding

When a trimmer string overheats inside the trimmer head and adheres together on the spool, welding happens. It is created by operating the trimmer at high speeds for an extended period while cutting over a resistant surface such as a fence or concrete pavement.

The increased friction generates excessive heat, softening the string and finally causing it to stay together. Because welded line does not feed from the spool, you must remove it and restring the spool.

While all trimmer string materials are relatively weld resistant, some string varieties have a higher degree of resistance than others. Because of the greater surface area, contoured lines are more weld-resistant than round lines when using the same material. The round string has the smallest surface area, allowing heat to accumulate more quickly.

Our final recommendation

The Oregon 21-380 Gatorline String Trimmer Line is unquestionably the best weed eater string since it is flexible and thick.

You’ll also notice that using the line reduces the working noise of your trimmer, resulting in a more quiet setting.

Another advantage is that it is most likely one of the universal line types used in almost any weed trimmer on the market.


What other weed eater string options are there?

There are numerous replacement string trimmer heads available on the market. Most are marketed as universal, which means that depending on the label, they should fit just about any electric, cordless, or gas-powered instrument.

However, read the instructions provided with your string trimmer and the alternative you are contemplating to ensure compatibility since some can be quite expensive.

Most alternative trimmer heads are for gas-powered versions (electric and cordless alternatives are, unfortunately, difficult to come by) and include simple, easy-feed parts, pre-cut line heads, and even stringless, heavy-duty blade replacements.

Many of them will require some disassembly and reassembling, but I’ve found that, for the most part, the extra money and time are well worth the effort in the long run.

How frequently should I change my weed eater line?

You will see that there is no set time limit for when the trimmer line must be replaced. In a way, once it’s gone, you have to replace it. The queue isn’t moving down like perishables.

When the weed eater line is finished, you’ll know it won’t work properly. You could occasionally see a line from the base of your weed eater. Before consuming the herb for the first time, check to see how much line is left that day.

Many individuals believe that the weed eater line should be replaced more regularly than it is. It’s inconvenient to wind trimmer line around the spool constantly. Here are some suggestions for increasing the number of times you must move the line:

The first thing you may do is utilize the right weed-eating approach. However, you should keep the type of string and the size of the spool. Some of the topics we explored before.

Are all string trimmer lines the same?

No. String trimmer lines aren’t all the same. There are numerous brands available, including those that produce fuel-powered, electric, and cordless variants, each with its trimmer head from which the line is fed.

Many of these heads are similar enough from one brand to the next that a regular weed wacker line can be used from one make and model to the next, but when making a purchase, pay attention to how the line is utilized, the shape, and the cord diameter.

What is the best string trimmer line size for the job?

The size of the weed trimmer line is proportional to the size of the material being cut. The larger the weed, the thicker the line you’ll need to use. Smaller grasses or weeds in the 0.60-0.80-inch range will require a fine line in the 0.60-0.80-inch range.

Weeds with a medium diameter necessitate a cutting line of around 0.11 inches. Larger items, such as tiny branches and dense undergrowth, fall into the 0.15+ group.

The 0.15-inch lines are normally regarded as professional-grade and are constructed not only for durability but also for prolonged use, and are used for industrial sites, estates, and other vast areas of the landscape.

Weed eater string sizes are an important factor to consider when calculating your requirements. You should read your string trimmer’s manual before purchasing a line to ensure it can handle the size you need. Most models can only take a specific amount of weight.

How thick is the weed eater line?

Trimmer line comes in sizes ranging from.065 to.170-inch. A large diameter line necessitates a larger trimmer head and more power to operate. Before attempting to load a new size, verify the weed wacker’s operator’s manual for compatibility.

Is a square trimmer line better than a circular trimmer line?

The Square trimmer line features four firm cutting edges designed to aggressively cut through coarse weeds and green underbrush, where it thrives. Because of the lower wind resistance, round lines are quieter and more fuel-efficient. Because it is made of more material, it is also more durable than a straight line of the same size. The round line may be the best option for normally weed-free lawns.

How do I put a new weed eater string in?

Some string trimmers require pre-cut line lengths. Others employ one or two long lengths of line wound onto a spool. You may need to remove the spool from the housing or load it in place. For complete instructions for your trimmer brand and model, consult the owner’s manual or the manufacturer’s website.

In what direction should I wound the weed eater string?

Wind the thread in the opposite direction that it is turning. Most of the time, you’ll want to wind the string counterclockwise. Many trimmer manufacturers imprint an arrow on the spool to indicate which way to wind the string.

How often should I replace the weed eater string?

It would help if you simply changed the string when it runs out as long as it is feeding properly and in good operating order. A string that has been exposed to the elements for an extended period can become brittle and must be replaced.

What is the distinction between trimmer and weed eater string?

Despite their various names, there is no difference between trimmer line and weed eater string. The products are known as weed eaters in some quarters and trimmers in others, but they are all the same.

Is a thicker trimmer line preferable?

Depending on the vegetation type, a thicker trimmer line may be a preferable alternative because it is more robust and adaptable for heavy brush and weeds.

The thick line’s basic idea is that it packs a more strong punch.
Remember, the thicker your line, the longer it will last.

It will also necessitate more power from your weed eater to perform as efficiently as a narrower line.

You may also discover that a thicker line is less prone to break apart when it comes into touch with curbs and driveways.

Is the trimmer line made of biodegradable materials?

Unless environmentally friendly businesses make your trimmer line, the answer is a no. Mower strings, on the other hand, are single-use plastic — a source of pollution that few people are aware of.

Trimmer strings will disperse into small plastic bits during operation. And these fragments will be mixed with your plants and soil. Unfortunately, most mower lines are composed of durable plastic that can take thousands of years to degrade completely.

Choose a trimmer line with high durability if the environment is a concern. It contributes to reducing the number of times they break and emit plastic into the environment. A string from a biodegradable brand would also be wonderful.

Is the shape of the trimmer line important?

The shape of the line is important. That is why it was created.

String forms are classified into four types: round, multi-sided, serrated, and twisted. Line shapes, like line size, largely depend on your trimming requirements. The cutting effectiveness of the trimmer line increases as it transitions from round to twisted, but its strength decreases.

As a result, the spherical structure is always the best choice for household use. It is capable of handling light tasks such as lawn clipping and has a lengthy lifespan. The string shape will be different when it comes to industrial needs or heavy labor. Strings with sharp edges will be preferable since they have a greater cutting capacity.

Why is my trimmer line constantly breaking?

There are various reasons your line may be breaking all the time, ranging from poor construction to incorrect off-season storage.

Even if you’re working with only fairly dense vegetation, the more brittle your line is, the more probable it is to break.

If you discover that your current brand has low longevity, it may be a good idea to try upgrading to a more expensive type of line that does not have a round diameter.

Why does my weed eater string get stuck?

The cable that accomplishes the actual trimming on a weedeater or string trimmer is sometimes called line or string; the rope is the starting cord on a gasoline-powered device. This rope can become twisted and become stuck. However, the problem is sometimes in the starting coil. Take the engine out of the trimmer shaft.

How can I extend the life of my trimmer line?

The most important advice for extending the life of your trimmer line is to ensure that it is properly prepared.

Many professionals believe that putting the line in a freshwater container during the off-season helps to retrain the line’s suppleness, allowing it to last longer.

You should also consider soaking your line before feeding it into your trimmer, improving its flexibility and letting it withstand the greater strain.

Developing the right weed-eating technique can also assist you in limiting the amount of trimmer line you use in a single season.

You should also avoid specific items in your yard, such as hardened surfaces, fences, and lawn furniture since this will help to prevent breaking.
