Do you need to dethatch your lawn with a lawn dethatcher? No matter how much you care for your lawn, if you leave it a couple of years without dethatching it, it will become unhealthy.
The lush green grass that makes it up will stop growing and they’ll start dying. No matter the amount of water or fertilizer you add, it will still keep dying because too much thatch is preventing the lawn from getting the necessary air and other nutrients it needs to be healthy and grow.
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, stems and runner, leaves and roots.
Moderate amounts of thatch is okay, but when it has built up over a few years without being checked it starts preventing air and the necessary nutrients needed for your grass to grow. It even harbors insects and pests which further harms and inhibit the growth of your lawn.
Hence, if you notice this, the necessary thing for you to do is to use a lawn dethatcher to dethatch or remove the thick layer of thatch or dead organic matter beneath your lawn grass. So that your lawn can start breathing fresh air again and receive necessary nutrients essential for it’s growth.
You can either hire a landscaper to help you do this or you can buy a lawn dethatcher and dethatch your lawn by yourself.
So, in this post, I’ll be reviewing the 7 best lawn dethatchers you can use to get rid of the thatch in your lawn, so that fresh green grass can start growing again.

Then when you’re over the lawn you can raise the wheels so that the tines gets in contact with the lawn, this way it can work as straight dethatcher, by simply pulling it through the lawn and combing through the grass, removing the thatch along the way.
Finally, you can add weights to the dethatcher so that it penetrates more into the thatch, soil and grass roots, scraping through the thatch and scarifying the soil. This should come in handy when you’re trying to seed your lawn.

2. Greenworks 14 inch 10 Amps Corded Dethatcher - Best Electric
At first sight, looking at the size and the price, I thought the Greenworks 14 inch electric dethatcher was just another joke. An electric tool for dethatching? Pfff! What a joke!
However, the incredible reviews it’s garnered made me to check, and it turns out, the joke was on me.
Turns out, I was just a doubting Thomas. The Greenworks corded electric dethatcher is one workhorse that will give the thatch in your lawn a run for their money. It’s efficient, and does the job of removing thatch from your lawn effectively.
All, you have to do is plug it in, push the start button, and push the dethatcher. 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 a lawn dethatcher at your local hardware store.
At the heart of the Greenworks lawn dethatcher is a powerful 10 amp motor which provides the power that spins 18 sharp tines which spread over a part of 14 inches in width, working unanimously to remove the thatch from your lawn as you push it through.
The tines can be moved or adjusted in 3 different position or depth depending on how much thatch your lawn has accumulated over the years.
Also included when you purchase the Greenworks corded electric lawn dethatcher is a full set of replacement tines for the 18 tines which the dethatcher uses.
Take care not to stay in one position when the machine is working as it can damage the grass when left running in one position.
For optimum performance it is recommended and advised that you make use of a heavy duty extension cord for connecting the Greenworks dethatcher 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 volatage 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 the best lawn dethatcher you can afford 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 the Greenworks electric dethatcher. You’re limited by the length of power cord you use for the dethatcher, 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.
