Why Do I Need A Dethatching Blade?

In addition to being less expensive than dethatching machines, dethatching blades are a user-friendly way to keep your lawn free of thatch.

These blades that are sold separately are designed to be easily fitted on a lawn mower. To make sure it does its job, you should pick the right blade according to the type of lawnmower.

The good news is that most blades out there and the ones we chose can be installed on most lawnmowers; however, always check their compatibility with your lawnmower before clicking ‘buy’.

Of course, since lawnmowers aren’t designed to eliminate thatch but to cut grass, you can’t expect the same efficiency and optimal work as from a dethatcher.

These specialized machines don’t just save money, but also ease cleaning and are long-lasting. Still, a dethatching blade will certainly come in handy!

How To Dethatch With A Lawnmower?

To dethatch grass using your lawnmower, you need to change out its standard blade with the dethatching blade.

After installing them, another important step is to set the mower’s height to the appropriate setting. Begin by testing it on a small, less visible part of the lawn and keep moving.

Remember that a dethatching blade, when left in one place, will create crop circles and take out big amounts of material in a single area!

Then, observe the area. If needed, lower the blade height until it makes the best contact with the grass. The correct height will remove brown and dead thatch without harming the live grass.

While dethatching, you should also make pauses to check the blade.

The tines may bend or blunt while working. This will decrease their efficiency and if happens, replacement with another is necessary.

To collect the thatch and other debris later, you can use a rake.

What Does A Dethatching Blade Do?

The way these blades work is that they pull the wires or springs they have through the grass.

As these springs move around, they pull and rip out thatch, i.e. dead grass and other debris. After you’re done, you clean the debris and that’s it.

Which Factors Should I Consider Before Buying?

Without a doubt, before we buy something, we need to make sure it meets certain criteria.

For a quality dethatching blade for your lawnmower, make sure it checks out these features:

  • Quality materials and construction

For your dethatching blade to last and perform optimally, it’s necessary to be made of quality metal or plastic.

The former is strong and doesn’t wear off fast, although they may be more expensive than the latter.

The latter may be cheaper and gentler, but may not be as durable and tough as metal.

  • The tines

Tines of dethatching blades are often made either from metal or plastic. The metal spring tines will dig deep into the thatch layer and eliminate it efficiently.

They’re long-lasting and strong. If you want a gentler option, plastic twines are amazing because they won’t cause excessive damage.

  • Size (width)

For a dethatcher blade to fit your mower, it needs to have the same width. If the cutting deck has a smaller width than the blade, the installation will be challenging.

Moreover, the width also matters for the area you plan to dethatch.

If it’s a smaller or a medium lawn, a 16-inch would do just fine and it will help you finish the job timely.

However, although you can use the same for larger surfaces, remember that it will take you more passes than you would need with a larger option like 21 inches.

  • Is it universal or not

One of the best advantages of dethatching blades is that most of them are universal, that is, no matter the brand of your lawnmower, they will be easily installed.

Moreover, they usually come with all of the needed washers and adapters for an easy, effortless installation.

In this way, frustration is brought to a minimum and you can dedicate your time to the dethatching process!

  • Price

A major advantage of dethatching blades, especially if you already have a lawnmower and not a dethatching machine, is that they’re budget-friendly.

Namely, since you can find models in the range between 15 and 20 dollars, going a lot over it would end up damaging your budget, rather than helping you save.

How to Install a Dethatching Blade on a Lawn Mower?

In a couple of steps, you can easily transform your lawnmower into a dethatching tool.

First, you need to dethatch the spark plug wire and tilt the machine on the side. Find the spindle bolt that’s holding the blade on the underside of the deck.

Put a wooden block between the deck and blade to prevent the blade from turning. Use a socket wrench to take out the spindle bolt.

Put the blade aside and install the dethatching one on the spindle with the springs/tines faced down.

Tighten the bolt to keep the blade secure. You then reattach the plug wire and adjust the height. To put back the lawnmower blade, repeat the steps in reverse.

Should I Mow Before Dethatching?

Before you do the dethatching of your lawn, it’s recommendable that you’ve mowed it so that it’s at a lower height. And, when dethatching, do it when the soil is moist, not very dry.

Avoid dethatching on wet grass since it can yank the turf out by its roots and make big bare spots!

How to Care For My Dethatching Blades?

When you care for your dethatching blades properly, they will function optimally and last longer.

To keep it this way, ensure you sharpen it regularly, always install it the right way, and replace any worn-out parts.

Dethatching or Aerating?

Both dethatching and aerating are essential lawn care procedures that we do during late winter through late spring.

And, they both serve to ensure the grass-root gets the key nutrients as well as oxygen and water. In this way, the grass will have better chances of growing and staying healthy.

However, on one hand, aeration causes the compacted soil to break down while dethatching will remove the thatch layers, dead grass, and other debris from the top of the soil.

Despite having similarities, every procedure has its advantages, and each is done with different tools.

With it, you can use your lawn mower to dethatch.

Our best pick is awesome for those looking for a quality dethatching blade that performs optimally and lasts for a long period. But, our budget pick is also awesome, but less costly!
