For starters, this dethatching blade is the longest one on our list. In reality, it is 21 inches. Meaning you get to thatch the lawn more efficiently. Hence, you will be saving yourself a bit of hassle and a lot of time.
However, that is not all. This product is also compatible with a lawnmower that supports 22 inches. Now, we know that they won’t be a perfect fit. But you can still get them if your mower supports 22 inches dethatching blades.
Plus, this blade fits all the walk-behind lawnmowers. And let’s face it nowadays we only use walk-behind lawnmowers. So, no matter what brand of lawnmower you have, this blade will be a perfect fit for you. Provided that the size fits.
Another thing you need to be careful about is the central hole. Now, the blade will match your lawnmower. But it has to support blades with 3/8″, 7/16″ & 5/8″ central holes. Otherwise, the blades will not be a complete fit.
As for usability, they are pretty easy to install. You won’t face a lot of problems while trying to attach the blade to your lawnmower. That makes it very easy to use and you won’t have to struggle with the blade even if you’re a beginner.

But that doesn’t mean this cannot be the one for you. Come on, let’s find what if it has features that match your expectations-

Moreover, this product comes with a cover washer and 6 reducing washers. These washers have varying sizes. And they are- 3/8 in., 7/16 in., 9/16 in., 1/2 in., 5/8 in. and 3/16 in.
But that is not all. Like the previous blade, this one has a universal application as well. That means that this dethatching blade will fit all the lawnmowers with ease. So, no matter what brand of lawnmower you use you get them.
However, remember that the shape of the central hole is star-shaped. That means your lawnmower has to accept star-shaped blades for this to fit. Otherwise, you will have to return the blade and get them replaced.
Moreover, this blade’s size is 16 inches. Now, we know that it is lower than the previous product. But hey, it still does get the job done. It might not be as efficient as the first one but with effort, it will also show the same results.

As for the width, it is 2-1/4 inches in length. So, do ensure that this size is suitable for your lawnmower. Otherwise, they won’t fit. And another thing to keep in mind is the central hole. This is 1 inch in length.
Again check to see what size your lawnmower supports. Now, if all the measurements match then this is a pretty good pick for you.

However, if you are thinking that this product will offer less because of the low price then you are wrong. It has so much to offer within that budget. For instance, this blade has metal dethatching springs.

- Weight: 33.6 Ounces
- Product Dimensions: 16.14 x 2.28 x 0.16 inches

At the very end of our list, we have the New Stens 370-019 Power Rake. We know that this product did not score very high on our list. But it surely did beat all the other products in the market. So, give it a chance. Let’s find out what this one has to offer-
To start off, we have to mention that this is the most budget-friendly product on our list. Now, blades are something that needs to be changed because they become dull or chipped. So, being cost-efficient makes sense.
Plus, you have to buy them so often that it might seem like a struggle to waste a lot of money on them. Hence, people do look for something within a good price range. However, the New Stens company didn’t compromise with the product.
New Stens make them out of high-quality metal so that they can be of service for quite a long time. At least, a few months so that you don’t have to make frequent trips to the local hardware store.
Moreover, this is a universal blade. So, it can fit most of your lawnmower. But the condition is that the lawnmower has to support this size.
Now, what is the size of this blade?
Well, this blade is 16 inches long. So, as long as your lawnmower supports this you are all set. You won’t have to worry about the blade not fitting into your lawnmower because of different brands. This makes things a bit easy.
Plus, you get to turn your regular lawnmower into a dethatcher with this low-priced product. So, you see, you won’t have to spend a lot of money on high-end machinery for a dethatcher. You can have it pretty easily.

Additionally, the grass seeds can also have a better reach. So, you can count on your lawn to have more green plants after you dethatch the garden with your new blade.
Is Compatibility an Important Factor?
The number one thing to focus on is the compatibility of the detachable blades. You see, different blades are designed for different types of lawnmowers. So, if you randomly purchase detachable blades chances are they won’t fit.
After that, you will have to return the blade and get another one. And that is a hassle you probably don’t want to go through. But there is a solution to this problem.
Most of the blades are universal. That means they can fit any type of lawn you throw in its way. Let it be gas-powered or the modern electric ones. And the best part is that most of the blades on our list are universal.
Blade Sizes: Do They Even Matter?
Pay heed to the size of the blade. Now, this doesn’t only include the length of the blade. Nope!
You will have to notice the thickness and the width of the detachable blades as well. All those measurements need to match with your lawnmower to ensure that they fit like a glove.
This is because if you go for the bigger size blades they won’t fit into your lawnmower. That is obvious. However, if they are too small they won’t be as efficient as you want. So, that is a complete waste.
Holes and Shape Of the Lawnmower: What to Consider?
The number of holes in the detachable blades varies. Typically they have 3 holes. These 3 holes attach to the lawnmower. The blades must have the same number of holes as the lawnmower. Otherwise, they will not fit.
Moving on, the shape of the hole for the blades also matters. They have to match with the lawnmower otherwise they won’t fit.
Generally, the middle holes for the blades are 5-point star-shaped with round holes to the side. Other times the blade holes may be rectangular shaped, they might have star-shaped holes but instead of 5 points, they would have had 7 points.
The Blade’s Hole Size: What to Measure?
Additionally, it’s crucial to know the size of the holes. Now, while you measure the hole be sure to take two types of measurement. One is the inside size and the other one is the outer side of the hole.
This is because the detachable blades come with washers for blades of different shapes and sizes. Hence, it is important to pay attention to the blade hole size.
Another crucial measurement is the distance between the holes. Measure the distance from the center of the two outside side holes. They will also determine whether the blade will fit your lawnmower or not.
Is Durability a Crucial Part?
You will be investing quite a few bucks on the detachable blades, so it is natural to want them to last long. Besides, it is a hassle to go to the store for these tiny parts.
Thus try to find dethatching blades that are made of steel. They work to ensure that your blades last longer. That is because steel is quite durable in nature. So, they do work for a long time without you needing to change it.
