Different Types of Brush Cutter Blades (Explained With Pros and Cons)

If you are dealing with a lawn which has overgrown weeds, then you must have at least thought once about the brush cutters. They are the most amazing solution you can pull out for your lawn. However, in brush cutters, the blade is what does the magic. If the blade is not on point, things can turn into bad.

Anyways, there are different types of brush cutters available in the market suitable for different needs. I have written this article only focusing on the types of brush cutters along with their advantages and flaws as well.

So, let’s get started!

What Are the Types of Brush Cutter Blades?

Mainly, there are 4 different types of blades for brush cutters. They are: Chisel, Smasher, Knife, and Mulching. They are suitable for different tasks and come with their own set of advantages and disadvantages.

Here I am explaining each of the types in details:

1. Knife Blade

This is the most common type of blade used in brush cutters. They come with a sharpened knife edge on the front edge of the blade. Knife blades work by slicing through the vegetation. Knife blades can come in different shapes but there is one thing common in every knife blade, which is all knife blades are stamped or lasered from thinner steel sheets.

As mentioned, from rectangular to the round shape, knife blades can come in any shape. But the most widely used shape is the star-shaped which comes with four cutting edges. They are easily found on anywhere. The number of sharpened edges in the blade plays a big role in how the blade will perform.

And when it comes down to mulching, the rectangular and star-shaped knife blades are the ones which pull the best. They are highly effective since they go vertically through the vegetation. There is a blade made by KIWI, the airecut blade. This is one of the best knife blades for mulching. This blade will cut things and throw upward which looks good.

The Pros

•    Comes at cheap price.

•    Good on cutting soft things.

•    Lasts long if maintained well.

The Cons

•    Gets dull faster.

•    Can break if encounters hard rock.

2. Chisel Blade

These blades are little similar to the knife blades since some knife blades come with sharp teeth as well. However, chisel blades are circular shaped and have sharpened teeth around the edge of the blade and that is what cuts through the vegetation.

Chisel blades are highly effective. They are like chain saw blades, actually, you can use chain saw blades on the brush cutter if you want. In horizontal cutting, chisel blades perform excellently, it can make the in-depth cut. You will be able to cut branches effortlessly larger than even 50 to 60mm.

That being said, in order to get the best out of this kind of blade, you will need a powerful machine that comes with good torque and power. The faster the blade rotates, the better results you will get. And be very careful when handling them.

This blade doesn’t offer good mulching service since the round-shaped blade doesn’t move up and downward in the bush.

Types of teeth

Chisel blades come with different types of teeth, each kind works little differently from the other one.

•    Steel Teeth.

•    Chainsaw teeth.

•    Tungsten Carbide teeth.

The Pros

•    Very effective cutting performance.

•    Works well on hard materials as well.

•    Highly-durable blades.

The Cons

•    Requires powerful machine.

•    Comes at an expensive price because of the shape complexity.

3. Smasher blades

They are completely different from the previous blades which come with sharpened edges. Smasher blades don’t come with any sharp edge. As the name suggests, they are smashers. They rely on their thin thickness and the weight to smash through the vegetation. These blades can be used by any brush cutter. That being said, they are now not highly available.

But when sharp knife blades wear out completely and get dull, they act like a smasher blade. As far as I know, there are only a few flail type smasher blades available in the market and one of them is Australian made weedwakka blade. These blades are only good for grass and watery weeds.

Never try to cut through any hard materials with this blade, you will end up damaging it. I have tried personally and only found this Australian made weedwakka blade to be amazing. Having that said, since they are very lightweight they can’t hit any heavy thing. However, smashing blades are also a good option for mulching watery weeds and grass.

The Pros

•    Highly efficient.

•    Requires no maintenance.

•    Good for grass and watery weeds.

The Cons

•    Can be expensive.

•    Not highly durable.

4. Mulching Blades

As the name implies, they are designed for mulching leaves and they are not widely used. Mulching blades are not even available widely. I have never used one but I have contacted some people who used it, and according to them, they work well on mulching leaves and branches.

The Pros

•    Suitable for heavy things.

•    Highly effective on mulching leaves and branches.

The Cons

•    Not found everywhere.

•    They require high power.

5. Brush Destructor

This is another blade type that I didn’t mention earlier and the reason is, it is a 4-in-1 blade. Don’t get shocked! This brush destructor blade can work as a knife blade, chisel blade, smashing blade and mulching blade.

That means, if you get this, you don’t have to purchase those blades separately. Do not overlook its quality since it comes with all the blades. It works as effectively as those blades would have worked separately.

The Pros

•    Highly effective.

•    Versatile.

•    Durable.

The Cons

•    Can be a bit expensive

Conclusion

I hope by now you are aware of the different types of brush cutter blades available in the market. If you are dealing with watery weeds and grass, the best knife blade would be the Weedwakka. A lot of gardeners are already using that blade and is satisfied. For highly wet and thicker grass, Airecut blade by KIWI would be the best choice.

However, which type of the blade you would choose depend on what kind of task you have in your hand.
