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.

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.
