Weeds should be categorized as supernatural creatures. This is because they have the ability to steal nutrients and space from your plants while still draining the life out of you. Just one look at the weeds in your garden or lawn, and your energy goes from 100 to 0.

But not to worry. Today we're going to assist in the fight against these pesky little creatures by helping you get a weed eater head that will take all your problems away.

There are several names that weed eaters go by. You may have heard them being called weed trimmers, weed hackers, or even string trimmers. All these words mean the same thing.

What Is A Weed Eater Head?

A weed eater head is the main part of a weed eater that does the cutting. This trimmer head consists of a strong monofilament line and a rotating spindle. This line is what cuts the weed or grass that you're targeting.

The weed eater head is a part of the whole weed eater. However, it's the part that mostly comes into contact with the weeds. Therefore, it's prone to wear and tear more often than the rest of the trimmer.

This is why we're looking at some amazing replacement head trimmers so that you can continue fighting the good fight.

How Do You Choose A Good Weed Eater Head?

Let's look at some crucial factors you should consider as you choose the best trimmer head.

1. Purpose

Knowing where you'll be using your trimmer line and head will allow you to choose the right one. Whether you're dealing with heavy grass or deep undergrowth, you should be able to choose a head that aligns with what you're working on.

What your garden needs will influence the type of head trimmer you get. Will you want one with a trimmer line or one with blades? The choice will be based on what you'll be using it on.

2. Size

The size of your string trimmer head is another crucial factor that you should consider when making up your mind because it will affect cutting width. A small-sized head is good enough if you have a small yard that is not crowded by weeds.

Replacing a string trimmer head does not have to feel like hitting your head against a brick wall. There are lots of options, and several replacement heads feature universal compatibility to produce things more comfortably.

Size and weight often go together. Therefore, if you're working on a small lawn, it's best to get a smaller and lighter trimmer head. This will allow you to have more flexibility as you work because you won't have the extra weight lagging you down.

If you love maintaining your lawn and don't have that many weeds in your yard or garden, having a small weed eater head is a better option. You will feel the difference if you opt for a smaller and lightweight head if you've been using a larger one.

Your back will thank you. Conversely, if you have a large lawn or have large weeds, you'll need a bigger head. Bigger trimmer heads cover more ground, thereby helping you work faster. Although keeping your lawn or garden free from weeds is a necessary gardening activity, you don't want to spend hours doing it.

The materials used can also affect the size and weight of the trimmer heads. Don't shy away from plastic components. Although plastic has a bad rep of being less durable than other materials, this won't be the case with trimmer heads.

Remember that some materials like metal can't handle moisture like plastic can. Therefore, you'll have a higher advantage if you're using trimmer heads made of plastic. You can cut your grass and weeds even during the rainy season.

3. The Model

The model Tanaka 'No Brainer' really does not need any extended further explanation than its name. This tool is straightforward to use. The installation occurs in minutes, and reloading this head doesn't use much of your productive time.

It runs fluently for a long time and does not entail reloads as frequently as other heads do. One factor remains identical, though, and your yard will embark cut neatly and evenly after you have a Tanaka on the top of your trimmer.

4. Line-Feed Design

What is the line-feed method? The line-feed method is how the string gets fed out after it gets cut off. As you cut the pesky weeds, some part of the line may get torn away or ripped off. Therefore, a new line needs to be rolled out every now and then. This is the line-feed method.

If you are working around stones, landscaping blocks, walls, fences, and any other obstacles, you'll notice the line getting shorter. There are several ways your weed eater head will feed out more string. Let's look at the three main ways below.

a). Automatic Feed Head

As the name suggests, this process takes place without any manual interference on your part. As the line gets eaten up, it gets fed back out automatically. One thing to note with these trimmer heads is that they may be slightly more expensive than the other types.

After all, you are paying for the convenience of not having to keep feeding the trimmer line.

b). Bump Feed Head

Bump feed heads come with buttons underneath them that release more trimmer lines when you bump the head to the floor.

For the best results with this type of trimmer head, bump the head when it's spinning. You can also bump these bump feed heads on a stone or log as you are trimming.

c). Fixed Head

Fixed string trimmer heads require you to manually replace the trimmer line. This is why they are the opposite of the automatic trimmer heads. You can also find some of these weed eater heads having small blades in place of the trimmer line.

The advantage of these trimmer heads is that they are more durable than the other two. The reason for this is that they have fewer moving parts. This makes them easier to maintain.

5. Blade Type

As we mentioned above, some trimmer heads have blades instead of the trimmer line. The weed eaters that have blades are great if you are working with thick weeds or a heavy bush. If you plan on working on undergrowth, get weed eater heads that come with blades.

While we're on the subject of blades, let's talk about the material. You'll find some weed eater heads with plastic blades and others with metal blades. Therefore, how do you know which to choose?

If you are not worried about damaging your trees or your beautiful landscape, you can go with metal blades. These ones are very effective at dealing with thick bushes, but they can also damage your trees.

Moreover, you can also opt for trimmer heads that come with a wire brush if you don't want the blades. This can be a good idea if you want to work along your driveway or stone path.

6. Single or Dual Line

Trimmer heads can come as either single-line models or dual-line models. In which case would you need either?

The choice in which type to choose depends on the kinds of weeds you're working on. For example, grass-like weeds can easily be dealt with with a single-line model. In contrast, if you are dealing with robust weeds or a bushy undergrowth, you may need a dual-line head.

The best head is the one that works for you. Remember that these two types require different levels of maintenance. This is because the moving parts in a dual-line trimmer head are more than those in a single-line.

Why is it more difficult to maintain dual trimmer heads? Because you have to deal with loading and caring for the two lines. If you deal in commercial landscaping or heavy-duty landscaping, consider getting a dual trimmer head.

Otherwise, go with a single-line trimmer head that will serve you very well.

7. Durability

Durability is a no-brainer when buying anything. You should always aim to get the best bang for your buck no matter what you're buying. We mentioned above that you shouldn't be deterred when getting trimmer heads that are made of plastic.

This is because they are great when dealing with moisture and are often made of high-quality plastic. Plastic is also a great choice when you want to work with lightweight trimmer heads. Don't worry about how much punishment your plastic blades can take.

You'd be surprised by how sturdy these things are.

Nonetheless, look at the product details and what other customers are saying about the trimmer head you want to determine its durability.

8. Ease of Use

How easy is it to use your trimmer head of choice? The answer to this question should influence your choice above. We've outlined some amazing trimmer heads for you to choose from. We've also talked about the types of trimmer heads so that you can pick the right one.

We did this in our fourth factor, where we talked about line-feed design. The advantage of choosing a trimmer head that's easy to use is that you will have an enjoyable experience.

You should also consider the maintenance. The easier it is to maintain, the easier it will be to use. Why? Because you won't have to do much to get your trimmer head started after a long time of disuse.

9. Warranty

Why are warranties important?

One, they give you the confidence that the product is genuine and high-quality. Two, they give you the security that your investment is safe. No matter what happens, you'll be able to return the faulty product when you need to.

A point to note with the warranty is to ensure that you've read the terms and conditions. This will enable you to know when you are covered by the warranty and when you're not.

10. Compatibility

We finish off with a strong factor. Before adding your new trimmer head to the cart, ensure that it will fit in your trimmer or weed eater. You don't want to get your weed eater out ready to replace the head only to find that it doesn't fit.

Opt for universal heads that can fit into most weed eaters. Ensure that you check any disclaimers on your universal head that states products that it's not compatible with. Although many manufacturers can label their heads as universal heads, you still need to confirm that it's compatible with your product.

How Do You Change Your Weed Eater Head?

This is an excellent question that we're going to answer in a few quick steps.

Step 1: Clean the Head

Cleaning always proceeds most activities, and this is no different. Although you're going to be replacing the trimmer heads, you still want to work with a clean space.

If you're working with electric trimmer heads, ensure that the model is off and disconnect the power cord before starting the process. Safety first.

Ensure that the trimmer heads are completely cool before you start the process. Use an old towel to remove any grass or debris on the head before you get started.

Step 2: Read User Guide

Different trimmer heads work differently. Therefore, ensure that you keep the user manual of your trimmer heads for future references like this one. Anyway, assuming you kept the user manual for the head you are removing, this is when you take it out.

Go through the user guide for any instructions on how to remove the head. This is important because this is where you'll be able to tell whether you need to get extra tools or take additional steps. Nonetheless, most trimmer heads are removed using the same process. Therefore, you won't have to worry about this so much.

Step 3: Remove the Head

Removing trimmer heads may sound like a daunting process, but it's actually quite easy once you get the hang of it. Different trimmer heads are removed differently. Why? Because the model of the head determines how you're going to remove it.

A small screwdriver should do it for most models. First, look for a small hole found on the side of the dust cap. This is where the screwdriver goes on. If you don't find this hole, you'll need to use a wrench.

If you're using a wrench, hold your weed eater upside down and use the wrench to grasp the dust cap. Once your hold is secure, turn the head counterclockwise using your free hand. Twist the head of the shaft until it comes off.

Step 4: Fix the New Head

Fixing the trimmer heads requires you to go in the clockwise direction. Continue holding the dust cap with your wrench as you turn. One thing to ensure you do is to tighten the head completely. We cannot stress this enough.

Given the circular motion of the weed eater, if the head is not screwed on tight, dangerous accidents can happen. If you're using a screwdriver instead of a wrench, use the small hole on the dust cap.

Once the small hole on the dust cap aligns with the hole on the gearbox side, insert the screwdriver into both holes and hold as you turn the head in a clockwise direction. Once you're sure that the head is properly fixed, you can move on to using it.

For the last point, while string trimmer heads might not be very costly, you still don't want to purchase a new replacement now and then. So, whatever you wish to buy should be enduring enough.

Frequently Asked Questions About Weed Eater Heads

1. What are universal trimmer heads?

A universal trimmer head is a head that works with various models of weed eaters. You'll also find many universal heads with various adapters to allow them to fit.

Therefore, if you're looking for a head that will work with your trimmer but aren't sure what to go for, you can always get a universal head. However, as we mentioned earlier, ensure that you check the disclaimers to confirm that the universal head works with your model.

2. Are thick lines better for weed eater heads?

It depends on the kinds of weeds you're targeting. If you are dealing with weaker grass-like weeds, you don't need a thick trimmer line. Conversely, if you want to remove thick undergrowth or any other robust weeds, go for a trimmer line with a larger diameter.
