If you don’t have a dethatcher, you might have considered using a dethatching lawn mower blade to dethatch your lawn. This is a maintenance that you need to perform once a year, usually in the spring. It will remove the thatch so that your grass can receive nutrients and water, which allows it to be lush, green, and healthy.

Continue reading to learn all about dethatching blades and whether they work.

What Is a Dethatching Lawn Mower Blade?

A dethatching mower blade is similar to the blades on a lawn mower that cuts grass.

A dethatching blade has metal spring attachments that are used to remove light thatch from your lawn. They work best on small yards. 

There are two different types of dethatching lawn mower blades that can work with your mower. One is a blade with a metal spring attachment, and it works well for removing light thatch from smaller yards. You can use it for up to 1.2 inches of thatch, but it is important to make sure that they are set to the proper height. 

The other includes blades with nylon trimmer line attachments. This type is less effective, and it can hurt healthy grass. The problem is that the nylon will take out anything in its path, which includes dead debris as well as growing grass.

Advantages of Dethatching Lawn Mower Blades

The advantage of dethatching with dethatching lawn mower blades is that you won’t have to buy another piece of lawn equipment. These blades work with your mower, and you simply remove the mower blade and fix the dethatching blade in place. It can repair areas of the lawn that are covered in thatch, and it helps to aerate the lawn. It will remove debris and break through difficult mats of debris. 

You should dethatch your lawn as a part of your maintenance program, so you can use dethatching blades with your mower. You simply remove the mowing blade and replace it with the dethatching blade with the spring tines. Set your mower height at the tallest setting, and start dethatching.

Disadvantages of Dethatching Lawn Mower Blades

There are several disadvantages to using dethatching lawn mower blades. First of all, if you have thatch that is more than half an inch thick, they don’t work very well. In addition, it takes time to change out the blades when you switch from mowing to dethatching. 

A dethatching lawn mower blade works well for small yards with light to medium thatch, but if you have more of a build up, they don’t do a great job. You will need to use an alternative method to remove the thatch. Another disadvantage is that the tines can bend, and you need to keep an eye on them and make sure that you replace them as needed.

How Do Dethatching Blades Compare to Other Mower Blade Types?

There are different types of mower blades that you can use on your mower. Standard mower blades are also called 2-in-1 blades, and you use them to cut your grass and either discharge the clippings or bag them. They are horizontal blades that are designed to cut through and shorten the blades of grass.

Another type of blade is called a mulching blade or a 3-in-1 blade. It has more curves and a larger cutting edge. It can cut the grass and bring it back to the deck, and then it is cut a few more times so that it falls on your lawn in small pieces. These are good blades to use when you mow every few days, but if you use it on overgrown grass, the clippings can get clogged under the deck. 

The dethatching blade is a blade with vertical tines that cut through the thatch. It is not used for cutting grass or for gathering it up. It is used to cut through thatch and give your lawn the ability to receive water and food.

What Is the Best Dethatching Blade?

There are different dethatching blades available, but the best ones are universally compatible. They are versatile and durable, and if they have springs, it makes the blade more adaptable to different mowers. Take a look at three great dethatching blades:

Maxpower 16” Universal Dethatcher Blade

This set comes with three blades, and it can be used on a variety of standard sized mowers.

Oregon Universal 20” Dethatcher Blade

This dethatching blade has a 1” center hole, and it is designed to remove moss. It comes with a dethatching spring, and it works well with most mowers. 

New Stens Dethatcher Blade

This dethatching blade works with most mowers, and it has a simple design that is easy to install and maintain.

Alternatives to Dethatching Blades

There are other options for dethatching your lawn. If you don’t want to use a dethatching blade, you can use a dethatching machine. This is a much more expensive option, but dethatchers are designed specifically to dethatch your lawn, and you can use it every spring to make sure that your lawn stays healthy. 

Another option is a power rake. Power rakes are similar to dethatchers, but they remove the thatch and debris in different ways. While you can use a dethatching blade for thatch that is less than half an inch thick, you can use a power rake if you have a visible layer of debris or thatch on the lawn. It can handle thicker thatch. 

The power rake is mechanical and has a dethatching blade with rotating flails. These flails are aggressive about digging up thick layers of thatch. They can remove as much as four times the thatch that a dethatcher can remove. People use the power rake when they want to overseed. You just need to make sure that you have a visible layer of thatch on top of the grass.

Pros of Power Rakes

There are several benefits to using a power rake on your lawn, including the following:

  • You can rent it when you need it, so you won’t have to worry about storing it or buying an expensive machine that you only need once in a while.It helps you clear thick thatch from your lawn.
  • It allows your grass to receive fertilizers, nutrients, and water.

  • You can prevent diseases from harming your grass.

Here are some of my favorite lawn care products

Thanks a lot for making it to the end of this post! I hope you found it useful. Here are some lawn care products that I use and that I think you’ll also find helpful. These are affiliate links, so if you do decide to use any of them, I’ll earn a commission.

In all honesty, these are some of the basic products that I use and recommend to everyone.

Broadcast Spreader

This Scotts Elite dual rotary spreader is not a professional grade model but it’s excellent for homeowners.

I really like the edge guard on it. It’s really easy to switch on and off so it’s great for going around my driveway and flower beds.

If you’re not looking to spend hundreds of dollars, I’d definitely recommend this model. It spreads out a wide path and is great quality for the cost.

Backpack Sprayer

This 4-Gallon sprayer is my absolute favorite. It sprays for a really long time. I’ve had this sprayer for quite a while and I’ve never had the battery run out.

The adjustable pressure switch is a really import feature to me.

You can order a lot of accessories for this model but I’ve never really found much of a need for it.

Head Aerator

Hand aerators are great for small spots if you’ve got construction debris or a spot that constantly dries out.

You can also fill these holes with organic matter that will hold a bit more moisture.

This one by Yard Butler is an absolute bargain. It pulls nice long cores. I also use it for taking soil samples around the yard!
