Rated 4.7 out of 5 by 111 reviewers.
Rated 5.0 out of 5.0 by Great little machine We have done about half of our 5000 sq. ft. lawn. This dethatcher worked great. We do it it smaller sections to give the machine a break and so we will not be overwhelmed with the cleanup. It is easier than using a lawn mower. It is so much easier to use, and not back breaking, like the gas rental models. The assembly instructions make no mention of when to put the cord clips on. So put them on according to the picture before you assemble it. This model does not have a catcher, and frankly it would be a pain in the rear if it did. You would have to empty it every 5 feet with the amount of thatch that it pulls up. We are actually having fun using it. We received it via UPS about a week after ordering it online. March 18, 2015
Rated 5.0 out of 5.0 by A Real Workhorse ! This is a great machine for ripping out moss. If it is real thick you will have to make more than one pass, but this is a real powerful little dethatcher that won't bog down no matter what you throw at it. I will never use my thatch rake again as this machine is so fast and lightweight it actually makes the job rather fun. March 13, 2015
Rated 5.0 out of 5.0 by Versatile, lightweight and effective Using about 125' of extension cord I recently dethatched about 10,000 square feet of lawn with this lightweight unit which ultimately proved to be a very versatile tool. Because my yard is laced throughout with ornamental trees and stonework a heavier unit would have been extremely difficult to get in and around these objects without tearing up the good grass. This is one of the reasons why I thought I'd give it a try. (However, whenever a straight line path could be achieved it was just as effective and did a great job.) The only thing to be aware of is the cord, but the quietness of the unit makes up for this slight inconvenience. April 15, 2014
Rated 5.0 out of 5.0 by Great tool at a great price The 2-cycle gas powered mini-tiller with dethatcher attachment I've had for years died last season, and I wasn't looking forward to paying the high price of replacing it. Then I found the Greenworks electric dethatcher at Home Depot and decided to give it a try. Based on my first use it works better than the old gas powered model and is a lot easier to use. No more gas fumes and no more hearing protectors either. It's clean, quiet and efficient. You do have to watch the cord a bit to avoid tripping over it, but you get the hang of it pretty quickly. Also best to brush the thatch from the vent periodically, but no big deal. I highly recommend this tool. April 10, 2013
Rated 4.0 out of 5.0 by Good Little Dethatcher After pricing rental vs purchase of a thatcher, I decided to give the GreenWorks a shot. It arrived well packaged, with easy assembly and is housed in a pretty sturdy unit. I've got about a 1/2 acre lawn in pretty good condition so I was hoping it would be able to get the job done. This things an the 1" setting it took up much more thatch than I even thought I had in my lawn. And when lowered to 3/4" it does a descent job aerating as well. Came with a full set of replacement tines as well, but none broke during my use. I paid $150.00 and expect to get at least 4 or 5 seasons of use out of it (the same cost for rentals would be approx $375.00) April 2, 2013
Rated 5.0 out of 5.0 by UNMATCHED DESIGN & PERFORMANCE This is an amazing product. There is literally nothing else out there that will dethatch as well as this machine. It's the perfect mix of being effective and being gentle to your lawn. I've used it for 7+ hours now, and it's quite a relief to have this thing when you have an obscene amount of dethatching to do. The review I posted below, "FAILURE ON AN EPIC SCALE," was meant for a DIFFERENT electric dethatcher, which was disastrous in exactly the ways I describe. I have no idea how that review ended up on this product page. I've tried to get the Home Depot website to remove that review, to no avail. So please ignore it. July 30, 2012
Rated 5.0 out of 5.0 by WOW This little machine took a LICKING and is still ticking!!!! and it pulled up soooo MUCH thatch we ended up using the lawn mower to pick it all up.......LOL..... I threw the old thatch rake in the TRASH!!!!! Took my que's from previous reviews and did not start until the morning sun dried the moisture from the grass and it worked great without pulling the good grass out of the out for hidden sprinkler heads though......LOL March 11, 2014
Rated 5.0 out of 5.0 by Good purchase I dethatched my front lawn with minimal effort. This unit is lightweight and easy to use. I mowed the front, used the dethatcher, raised my mower up two notches and sucked up the moss. My local rental company was going to charge me $105.00 plus tax for a 24hr rental. I like this unit because I can do my back yard when I feel like it. I had the unit running for over an hour straight with no issues. April 29, 2015
