What to Consider When Buying String Trimmer Heads 

We know string trimmer heads can be a little confusing if you haven’t bought one of them before. That’s why we decided to explain every single feature you must consider before making the last choice. Check them out:

  • Types of Trimmer Heads

The first thing to think about is the type of trimmer head you’re getting. This mainly changes the way the lines are used. 

Fixed Feed

Instead of placing an entire spool inside the head, this one demands you to install each line individually. It’s the most popular type among multi-line heads, the ones that have 4 or more lines going out. 

The advantage of this type of trimmer head is the durability of the lines. Because they don’t come in spools, but individually, they tend to be thicker. This thickness increases their durability and power, not only lasting longer but also helping you cut sturdier vegetation without problems. 

As a drawback, fixed-feed heads take a bit of time to reload when the line breaks or wears out. 

Bump Feed

These work with a spool of line. However, you won’t have to do much more than just placing the spool into the machine for it to work. Yet, when the lines wear out or break, you’ll have to unwind the spool manually. 

Most bump-feed trimmer heads have only 2 lines going out. These lines can be either thin or thick, so they may wear out fast. That’s why they’re often needing a lot more maintenance than other options.

These are recommended for people with small gardens and yards. Because the lines are easy to reload but tend to wear out fast, they’re better in places with occasional use. 

Automatic Feed

If you don’t want to waste any time reloading, an automatic-feed trimmer head is the way to go. As the name says, these feed the line automatically once it wears out. In some cases, you will only have to push them down for the spool to release some of the line.

But it’s not perfect, though. Automatic feeds are more expensive, typically only work with thin lines, and tend to quickly wear out. 

Blade Head

For those who don’t want to be consistently reloading and/or replacing spools, nothing will work better than a blade head. These don’t use the typical lines but blades. The blades are made of nylon and can handle a lot more mileage than lines.

These blades can be more expensive, though. Blade heads are also less compatible with most trimmers and may break more quickly if you mistakenly pass the trimmer close to rigid areas. 

  • Number of Lines

Another vital part of every trimmer head is the number of lines it has. Most of the time, you’ll find two: single-line heads and dual-line heads. In some cases, the multi-line heads may also appear. Here’s more about each:

Single Line 

The most popular only have one line. Residential trimmers use a single line to make them easier to maintain. Apart from that, the spools tend to be more affordable. 

Single-line heads, however, are mostly recommended for thin grass and small weeds. Otherwise, they may not cut efficiently or cleanly. 

Dual Line 

Having an extra line to cut with ensuring a cleaner operation. This also increases the strength, cutting most weeds and grasses effectively. For heavy-duty jobs, dual-line heads work the best. 

Commercial trimmers often have dual lines for that. These require a bit more work to install, and the spools tend to be more expensive.

Multi-Line 

For maximum strength and accuracy, nothing meets multi-line trimmer heads. These can handle 

  • Line Length and Diameter

What is the total capacity of the trimmer head? This means how long of a line it can hold. The spool size will have a lot to do with how much the line lasts. 

For example, most lines have a length of about 10 to 15 feet. This typically means about 3 months of constant use. Of course, this will depend on the amount of use and type.

Having said that, we always recommend longer lines for the best results. 

Similarly, you’ll want to consider the thickness of the line. This is measured in inches. However, these often go from 0.060 to 0.105 inches. 

The thicker ones cut weeds and branches, while the thin ones are mostly recommended for thin grass and small weeds. 

It’s worth noting that most trimmer heads have a limit on the diameter of the line. Some often work with lines up to 0.095 inches. If you need a thicker line that doesn’t break or wear out quickly, make sure the trimmer head allows it. 

  • Line Shape and Material

Alongside the thickness, length, and the number of lines, you may also want to consider the shape. This typically includes square-shaped, star-shaped, and twisted shapes. Also, others are serrated or regular rounded.

As a general rule, going for square or rounded lines is the way to go. However, star and twisted shapes are exceptional as well. They cut grass more effectively. But they cost a bit more, of course. Serrated ones can cut thicker weeds and branches than the others. 

Once you’ve figured out the shape of the line, focus on the material. Most lines are made of nylon, but you often find some with extra reinforcements like aluminum or titanium. These are obviously more long-lasting.

Frequently Asked Questions (FAQs)

Feel like we left out a few important things? Don’t worry – we may go over them below:

Are string trimmer heads universal?

Not necessarily, but most of them can fit a wide array of string trimmers. Universal trimmer heads are popular, though, so you may find one of those out there. Check its compatibility before buying. 

Is a thick line better?

It could be better if it matches your demands. For example, a thick line can cut thicker grass and weeds. Also, they are known for lasting longer. But if you don’t need the sturdiness, a thin line could get the job done. 

How much does a trimmer head line last? 

It really depends on the usage. Most trimmer heads last anywhere from 3 months to several years. Those made with metals and reinforcements tend to last longer.

Does it take a lot of work to change a trimmer head?

No, but it depends. Most string trimmers offer straightforward designs for snap-on trimmer head changes.
