Thatch build-up can severely inhibit the growth of your lawn grasses. And to get rid of it, you need a lawn dethatcher or at least find someone that has one.
If you leave your lawn a couple of years without dethatching it, it will stop growing properly. The lush green grass that makes it up will stop growing and they’ll start fading and withering.
No matter the amount of water or fertilizer you add, it will still keep withering and losing its lush green look because too much thatch is preventing the lawn from getting the necessary air and other nutrients it needs to grow healthily just like a normal lawn should.
Hence, if you notice this, the necessary thing for you to do is to use a lawn dethatcher to remove the thick layer of thatch or dead organic matter beneath your lawn grass.
So that your lawn can start gaining the necessary nutrients essential for it’s growth.
You can either hire a professional gardener or landscaper to help you do this or you can buy a lawn dethatcher equipment and get the job done yourself.
If you’ve made up your mind to go the DIY route, then you’re going to need the tool that does the job. We’ve reviewed several models and we’ve listed 9 of the best here so you can choose the right one for your lawn.

First of all, you can place it in transport mode when you’re crossing driveways or walkways by simply lowering the no-flat tires it’s equipped with.
Then when you’re over the lawn you can raise the wheels so that the tines penetrate the lawn surface, and then you can simply pull it through the lawn to remove the thatch.
To make it work better, you can add weights on top of the dethatcher plate so that it penetrates more into the soil to remove the thatch thoroughly and even scarify the lawn. This should come in handy when you’re trying to seed your lawn.

2. Greenworks 14 Inch 10 Amps Corded Electric Push Dethatcher
|Dethatching Width||14 inches|
At first thought, looking at the size and the price, I thought the Greenworks 14 inch electric dethatcher wouldn’t really work properly or be effective due to the type of job in question i.e. pulling out thatch from lawns.
However, the incredible reviews it’s garnered made us check it out, and it turns out, it ain’t no joke to laugh about.
Turns out, it’s a top-notch electric tool you can rely on to get rid of the thatch in your lawn. It’s a corded electric dethatcher, so you don’t have to buy fuel to get it work. It’s efficient, and does the job of removing thatch from your lawn effectively.
All, you have to do is plug it in to an electric power outlet, push the start button, and push it around your lawn like you’re mowing the grass. It’s even self-propelling so you don’t have to exact too much force to get it going.
Even more surprising is the relatively low price it retails for. Just a little over the price for renting one at your local hardware store.
It comes equipped with a 10 amp motor which provides the mechanical power that drives 18 sharp tines spread over a 14 inch width as you push it through your lawn.
The tines can be moved or adjusted in 3 different position or depth depending on how much thatch you want to remove.
Also included when you purchase it is a full set of replacement tines for the 18 tines already installed in it.
Take care not to stay in one position when the machine is working as it can damage the grass when left running in the same position for long.
For optimum performance, try to make use of a heavy duty extension cord when connecting it to a power outlet.
To be specific, for an extension cord that is 50 feet or less in length, the wire gauge size (A.W.S) needs to be 14. Anything less than that can result in voltage drop and loss of power, which can cause the motor to overheat, and possibly breakdown.
Overall, the Greenworks 14 inch corded electric lawn dethatcher is definitely one of the best equipment you can get if you’re looking for something effective but inexpensive to get rid of the thatch inhibiting the growth of your lawn.
Of course everything is not rosy when it comes to using the equipment. You’re limited by the length of power cord you use for it, and the position of your power outlet.
You can only go as far as your extension cord will allow. Though this is one limitation that cannot be avoided when it comes to corded electric tools.

Also included are 10 inch semi-pneumatic wheels which comes in handy for transporting the equipment especially when pulling it over driveways and walkways with it.
Right from the driver’s seat, you can use a cantilever transport handle it comes with to raise and lower the trail and tines on and off the lawn. This also comes in handy for raising the whole equipment and riding on the wheels when you have to drive over a hard surface like your driveway.

What is thatch?
Thatch is the light brown layer that builds up over time between your lawn grass and the soil. It’s largely made up of decaying organic matter like dead and compressed grass, leaves, stem, runners and roots.
Moderate amounts of it is okay, but when it has built up over a few years without being checked it starts preventing air and the important nutrients needed for your grass to grow properly.
It even harbours insects and pests which further harms and inhibit the growth of your lawn.
