Types of String Trimmer Heads

Before we go deeper, we thought you should know that there are different kinds of string trimmer heads. You need to know which ones they are and how they work so that you can make a wise choice.

Let’s get straight into that, shall we?

Bump Feed

This is one of the most popular types of string trimmer heads and understandably so because it is user-friendly and highly reliable.

Bump heads get their name from the fact that they have to be bumped for trimmer lines to advance. They use a spool.

However, this kind of trimmer head tends to wear down faster thus needing frequent replacements even if it is easy to operate.

Automatic Feed

Automatic trimmer heads are almost similar to bump heads only that they come with a motor for spinning the line so that it advances automatically.

Now, with this type of head, you can do your trimming without stopping to advance the lone. Of course, this allows you to complete your job faster and seamlessly.

That said; the moving parts and electric components in this kind of head make it more susceptible to breakdowns. Therefore, automatic feed heads are not as reliable even with all their convenience.

Fixed Head

With a fixed head, you will be required to individually thread in the trimming lines rather than inserting the whole spool.

This kind of head is also usually heavier than the other two that we have discussed and uses tougher strings that will not break easily.

Since you will be threading manually, you will find it easier to tell how much line is available when using this head. For this reason, it is a popular choice with professionals who trim lawns or yards commercially.

Buying Guide: How to Pick Right Universal String Trimmer Head

For you to get the perfect string trimmer replacement, you have to consider several factors while shopping. Here are some of the factors.

Head Compatibility

Regardless of how functional or convenient the string trimmer replacement head you pick is, it will be useless if it doesn’t fit your string trimmer.

Nonetheless, most manufacturers will indicate what trimmers their heads are designed for. For this reason, you need to read the product description before making your purchase.

You may also want to note that there are universal replacement heads in the market that will function with virtually any string trimmer. You should seriously consider getting such.

Single Vs. Dual Line Head

Perhaps you don’t know this but trimmer heads can be a dual or single line. One is ideal for domestic use while the other is for professional use.

Why don’t we compare the two?

Single Line Head

Single line heads are ideal for domestic use and here is why. They require less effort to operate and do not cut as smoothly and swiftly as would be ideal for commercial use.

If you prefer trimming your yard or lawn, this would be the perfect string trimmer head to get.

Dual Line Head

As you may have guessed by now, professionals prefer this kind of head because it is ideal for commercial use.

Note that it is not as easy to use even though it delivers desirable results. With a dual-line, you can easily cut through tougher materials including thick grass, heavy weeds, and tree branches.

You also get cleaner cuts and durability.

Head Size

As you shop for a string trimmer head, you want to keep in mind that the size of the head has an impact on the cutting width and that is why you need to consider it.

When it comes to choosing the head size for your string trimmer, you want to consider what you intend to use the machine for.

If you have a smaller yard without many weeds, a small head will suffice. However, if you are dealing with thick grass and weeds in a larger yard, you will be better off with a bigger head.

Head Durability

Universal string trimmer replacement heads are generally not expensive but that does not mean that you should keep spending your money on the same. That means that the head you pick should be durable.

Now, as far as durability, you want to look at the quality of the construction as well as the material used. Most manufacturers use plastic but it should be heavy-duty plastic.

If you choose to get an automatic feed head, you want to ensure that it comes with first-rate internal components to guarantee longevity.

How to Install a String Trimmer Head

Now that you have an idea of how to choose the right universal string trimmer head, you are a step closer to figuring it all out.

You also need to know how to install the head accurately and although most manufacturers provide installation instructions along with their products, here are the steps you need to take when setting up your string trimmer head.

Step 1

The first step involves removing the spool. With most trimmers, detaching the spool involves a fast and easy process that requires you to simply twist and pull.

If this does not work, refer to your head’s manufacturer instructions.

Step 2

As soon as you remove the spool, you want to remove any remaining part of the head. Note that most trimmers have the head attached with a bolt or nut and if that is the case with yours, you will need a ratchet to loosen it before yanking it off.

Step 3

With the spool out, it is now time to install your new head and you do that by fitting the fender washer that comes with it over the wound shaft.

Once the washer is installed, you can slide the head over it and complete the installation by placing the adapter piece on the shaft and lining it up with the trimmer head.

Step 4

Lastly, you want to insert the final washer over the adapter piece and attach the retaining nut while tightening. The process is at this point complete so you can give your trimmer a test drive just to make sure that the head is functioning well.
