Why Do I Need An Electric Dethatcher?

The best electric dethatcher is an amazing solution for you if you’re looking to remove those small pieces of debris from your lawn. Get rid of all grassroots, stems, and dead leaves easily.

By regularly removing moss and ill grass, you help improve the grass’s health from within, which will also result in a better-looking glass.

Thatching is recommended at least two times every year. Learn more about the best thatching schedule here.

When the dethatcher penetrates the ground with its prongs, it surfaces out the debris. This in turn gives the grass sufficient breathing space which maximizes the growth and lushness.

Which Features To Consider Before Buying?

Before deciding that you need an electric dethatcher and scarifier, consider some of the most important features to ensure maximum performance and longevity.

These are some of them:

  • Power (Amps)

Electric push-behind dethatchers come with cords that need to be plugged into a power source for the motor to work.

You’ll notice that most corded tools powered by a motor are measured in amps.

Amps indicate the motor’s electrical current load that can be carried for an indefinite period of time, without decreasing the motor’s insulation and other electrical elements.

The faster a motor spins, the more air it draws through the motor to cool it down.

Amps help you measure the maximum time you can run it without upping the temperature limits.

So, by checking the amps, you’ll know how effectively the motor will cool itself.

The higher the amps, the more able the motor to run longer without heating up excessively. A 12-amp motor is considered a middle ground, while the average motor strength is between 8 and 15 amps.

Choose wisely since heat can kill a motor.

Consider that the weaker the amps, the more passes you’ll need to dethatch effectively.

On the other hand, a very potent motor with a high amp may tear up the grass and thatch, so take into account the type of grass and dethatching needs as well.

  • Cord’s Length

Most of the dethatchers come with electric cords that are only several feet long and are connected to an extension cord.

Hence, if you have a smaller lawn, having a cord of 50-feet or shorter should be just fine. Take into account that when you opt for a longer extension cord, problems with the power may occur and lower the amount of it which it delivers to the end of the extended length of the wire (Ohms law).

  • Tine’s Length & Width

In order to reach the ground surface and pull up the accumulated thatch, you need to choose a dethatcher with long enough tines.

Since every garden owner prefers grass of different lengths, find the adequate for your needs or opt with a model that provides adjustable tines.

What’s more, consider the width of the tine cylinder-this will determine the tool’s coverage with every pass on the grass.

  • Type of Material & Design

Electric dethatchers need to be made of quality and long-lasting materials and a durable casing to withstand all of the vigorous landscaping.

Thick plastic is great for the casing and it should be one that doesn’t crack or fade as time goes by.

When it comes to the tines, stainless steel is the best, as well as strong welds to ensure they don’t snap off when you’re digging out serious thatch.

  • Handle

Since it’s a push-behind dethatcher, it needs to offer a comfy, easy to use, and maneuverable handle.

Look for padded and wide handles that will keep your hands pressure-free and allow you to push the machine without any discomfort.

Moreover, some of these machines come with adjustable handles that can be lowered/elevated or folded to ensure different operating heights and easy storage.

These are quite useful and storage-friendly options.

  • Debris-collecting Bag

To shorten your time spent dethatching and to eliminate the need for raking up after loosening the thatch, choose models that come with a debris-collection bag as part of its design or as an add-on option.

Of course, you can always collect the loosened thatch with your bagging lawnmower after dethatching.

  • Eco-friendliness

Some users want eco-friendly machines.

This is a passion for creating a better world.

Hence, petrol dethatchers are more potent and aggressive and work optimally.

However, they’re not eco-friendly and generate CO2 emissions.

And, they may also have harmful effects like acid rain or breathing issues. Eco-friendliness is ensured with an electric or manual dethatcher since they produce no emissions.

How Does An Electric Dethatcher Work?

Powered by electricity, this dethatcher features spring stainless steel tines on the front which rotate and dislodge thatch and other lawn debris, while you’re maneuvering it by its handle.

In essence, using it is similar to a push lawnmower.

How to Use an Electric Dethatcher?

When the time comes (late summer or autumn) and the grass has established well and actively growing, it’s time for dethatching. Do it when the grass is fully dry!

Electric-run or gas-operated models need to be started first.

You plug the cord into an electric outlet and press the start button.

If there’s an add-on debris bag, set it up in advance. And, make sure you’ve set the tines to the desired level, as well as the handle’s height.

And then you move it onto the lawn by pushing it using the handle. When the handle is long and wide and adjustable, maneuvering is easy.

When you’re finished, you turn it off on the button and take out the plug. You remove the debris from the bag and put it back into its place.

Is There A Difference Between Dethatching And Scarifying?

When you use a lawn dethatcher and scarifier, the steel tines cut out the thatch and this is known as dethatching.

It’s a lighter and less invasive process than scarifying. When you’re done with dethatching, the lawn has a free passage to get air, nutrients, and water to its roots.

However, sometimes, when more serious action is necessary, scarifying is recommended.

This is done by lowering the machine’s tines and allowing them to penetrate deeper into the soil. This opens the surface and makes it a great chance to introduce new grass seeds.

Aerating vs. Dethatching

Oftentimes, people tend to confuse dethatching with aeration. Though both of these care methods work together to maintain your lawn healthy, they’re not the same.

Namely, aeration is the process of poking holes in the ground to allow the soil to breathe. This is an essential process if you have dense and compact dirt. Aerating won’t remove thatch.

For this, you need to dethatch after the aerating. This is essential if you want the grass to be able to get the needed nutrients and oxygen.

Can I Seed After Dethatching?

Sure thing. After you’ve dethatched and removed the thatch, do the seeding with high-quality seeds. If you live where it’s sunny, opt for grass seeds like Galaxy Kentucky Bluegrass Blend.

Moreover, it’s recommendable to apply compost to every 1000 square feet.

This will keep the seeds moist and provide the needed nutrients for germination. Use a roller if you want to push the seeds deeper down.

After seeding, don’t forget about proper watering!
