Wondering how to dethatch a lawn without becoming inflicted with a sore back and blisters on your hands? Who isn’t? As much as I look forward to Spring time and the great, Colorado outdoors, I always dread the thought of dragging a rake through the lawn, pulling up thatch, and then bending over to bag it. Dethatching a lawn is not only a bit tiring, and hard on the back, arms, and hands, but it is a tedious process, especially if you have a huge lawn. Even with my medium-smallish, yard, I always wonder where to begin. Even a small yard has a lot of dethatching surface if you’re going to do it all by hand. Since buying my Electric Kobalt Lawnmower 6 years ago, I am no longer able to use my inexpensive, Arnold Power Rake blade which I bought and reviewed here several years ago. Upon waking up one morning and realizing it was time to rake, I finally decided to look into an electric lawn dethatcher.

14-Inch 10 Amp Corded Model 27022

Greenworks Dethatcher

The Greenworks Dethatcher is a very light-weight, corded, electric lawn dethatcher. There are no blades to mess with from your lawn mower. It’s a stand-alone tool that does one job and one job only: Dethatches your yard. It comes with several, inch-long tines that rotate via an electric mower. There is no bag included, so keep in mind that you will still probably want a rake to rake-up the thatch in big piles or you can try using your mower with grass catcher to collect all the thatch. Upon first use I went over my entire lawn in a matter of minutes and was able to easily mow up the thatch into my grass catcher. However, I wondered if I had really done a good enough job dethatching. Though it seemed to I had only a half-bag of thatch. A week later I learned how to dethatch a lawn much more effectively with the Greenworks dethatcher. I will share it with you.

How to Dethatch a Lawn Electrically

How to Dethatch a Lawn

The key to dethatching your yard properly is to go slow and take your time. The Greenworks dethatcher, in fact, is very effective at pulling up the thatch if you focus on going over areas slowly, and spending more time on dry, heavily thatched areas that need more attention. You can also gently back-up, then go back and forth over an area several times. You will quickly notice the thatch piles up the most where it is most heavily thatched. Though the cord is a bit of a nuisance at first, I learned to route the cord to one side of where the job is and work away from it. It helps to do a lawn in two or three sections, so the cord is out of the way. You’ll notice from the picture that there are nice piles of thatch after the job was finished.

Piles of Thatch

The thatch shown here is after raking it into small piles. Only light raking was required. The job, overall, takes much less time and effort than raking by hand. My front yard shown here is very thin. I never get anymore thatch than this when I spend the extra time and effort doing the back-breaking work of hand-raking. I think dethatching the yard this way did a much more thorough job especially after doing a second run a week later. One of the benefits is that you won’t mind doing it again if you have to. It’s really pretty easy.
