What Is Dethatching?

Dethatching refers to the removal of surplus thatch and this is an essential gardening procedure for healthy and green grass.

Although organic is usually considered good, organic thatch can become an issue.

This is because lawns have three levels. The one on top is the one we see. Although you will see most of the results from your maintenance at this level, the action is happening much below.

The other level is the soil and the thatch layer is between the grass and the soil.

Thatch is an organic layer consisting mostly of grass stems, rhizomes, and stolons, which can be living and dead but haven’t decomposed or dissolved yet.

With this in mind, for healthy grass, both on the inside and the outside, you need to dethatch it.

And, a dethatcher is a specialized unit that can help you do it efficiently.

Why Do I Need A Tow Behind Dethatcher?

As we explained previously, thatch will build up underneath the lawn, on top of the soil; however, with a tow-behind dethatcher, you can clear up this layer and enable nutrients, air, and water to enter the soil and help it grow healthy.

This is pivotal if we want thriving grass. A tow-behind dethatcher is easy to use, efficient, and practical, especially if you have a lawn tractor that you’ll use to pull the dethatcher.

Tow-Behind vs. Front Mount

Dethatchers can be found in various types, but the most common ones are the front mount and the tow-behind ones.

The former is attached to the tractor’s front and allows you to easily see where you’re going and what you’ve achieved.

However, these models tend to be pricier and may also interfere with other hardware that’s front mount.

On the other hand, the latter gives you more choices in terms of features and width. And, they’re usually universal, meaning you can attach them on any type of tractor you have.

Still, monitoring the process will require you to turn back to see what’s going on or have another person nearby telling you what you’ve covered and how it’s going.

Which Features To Consider While Buying?

In order to choose the best tow-behind dethatcher for you, make sure you consider the most important features first.

Tines’ Width

As you’ll see in our review section, tow-behind dethatchers are available in different widths.

This directly influences the swath which will be created with every pass up and down the lawn. So, which one to choose?

One that’s wider or one that’s narrower?-This will depend on what you need and how big your yard is.

The wider ones will help you do the job faster than the narrower ones. This may especially be beneficial when dealing with large surfaces.

However, they do tend to cost more. If you have a small or medium-sized lawn, a narrower one will be perfect!


Being able to raise the dethatcher is helpful if you need to take it across roads or other harder ground.

And, you need to lower it once it’s on top of the grass you’ll be dethatching.

The good news is that all of the models we presented offer a lever that allows you to effortlessly raise or lower the unit’s tines.

How Much Weight It Can Carry

Oftentimes, tow-behind dethatchers come with a weight tray located above the tines intended for adding extra weight.

This is important if you want to clear matted and thick thatch efficiently. Also, you can add weight when you want to scarify and till the surface of the soil.

The standard weight these dethatchers can carry is around 70 lbs. Some models can carry up to 150 lbs. or even more.


To be able to transport your dethatcher easily through different terrains, you don’t just need an adjustable handle, but quality and sturdy tires as well.

They need to be made of quality materials to be used outdoors. And, they also serve to optimize the unit’s balance.

The most common types you’ll encounter are pneumatic or semi-pneumatic. They’re similar to the ones of trucks and cars.

They can be of two types, ones filled with air (air pneumatics) or the ones made of rubber which are considered less prone to punctures (solid pneumatics).


Even though the best tow-behind dethatchers are made to last, things may go wrong. Namely, the pulling of the unit up and down and dragging the tines on the ground may cause them to bend or even worse, break.

This is why it’s essential to check the warranty before making the purchase.

A standard warranty is 1 to 2 years among the best models; however, sometimes, you can also find products offering a longer warranty like 3 years.

How To Use And Care For My Tow-Behind Dethatcher?

The dethatching process will be the most effective when the tines of the dethatcher won’t be affected by soil clumps or debris on the surface. Hence, make sure you use a lawn roller before the dethatching to level out any bumps or crevices.

You should also mow the grass and take out the sticks and bigger leaves with a sweeper or a vacuum. Some of the models we presented are 2-in-1, i.e. both a dethatcher and a sweeper, so they ease things a lot!

Then, after assembling the dethatcher and attaching it to the back of your tractor, make two perpendicular passes and make sure they overlap each time.

Then, sweep up the loosened thatch with the rake or a sweeper.

How Often Should I Dethatch My Grass?

Dethatching should be done at least once per year in early spring to decrease the risk of illnesses. And, opt for a second dethatching session in the autumn to keep the lawn green and healthy.

Do it after you’ve watered the grass or after rainfall. This is when removing most thatch is easier.

Avoid doing dethatching in the dry summer months since this may overexpose its roots.

When It’s The Best Time to Dethatch My Garden?

To check if it’s time to use the dethatcher, use a spade and take out a small plug from the lawn from a not-so-visible area.

If you notice more than half-inch of thatch, it’s time to take out the tool from the garage.

Dethatching can be done easily by attaching the dethatcher to your tractor unit behind or in the front. The ones we discussed today are tow-behind models which are easy to use and practical.

Don’t forget to remove the thatch after the dethatching. It will be left on the top of the grass. You can collect it with a sweeper or a rake.

Or, opt for a vacuum mulcher if you have other errands to do and you’re short on time!

Does Dethatching Damage My Lawn?

When done adequately, dethatching is awesome for a healthy lawn. It encourages oxygen, water, and other nutrients to penetrate the soil easier.

However, you should only do it when it’s the right time of the year, i.e. when it’s growing. This helps it to quickly recover from any potential injury the dethatching may have done.

Although we mentioned when it’s the best time to do it, you should also consider its type. Namely, for the cool season grasses like the Kentucky bluegrass one, early fall or late summer is the best period of time.

On the other hand, early summer is preferable for warm-season grasses such as the Zoysia one.
