Size: 13A Dethatcher / Scarifier
This inexpensive, dethatching machine is amazing. I’m so glad I bought it. It is very lightweight and easy to use; it pulls itself along. The amount of thatch that flows out the back amazing. It left a layer of loose thatch material about 2-3 inches think. I filled TWENTY 42-gallon bags with thatch. My lawn area is about ½ acre, likely a bit less. A few things I learned. -- Cut the grass a little lower than usual. This makes it easier to keep the machine moving through your lawn. -- Dethatch when there is some moisture in the ground—not real wet, not dry. I did it after a good rain. I don’t think the dethatcher could do a good job if the ground was dry and hard. -- It seemed a good idea to heed the manufacturer’s recommendation to use an extension cord of the proper wire gauge depending on length. (The manual says you can burn up the motor if the extension cord is not of sufficient wire gauge for the lengthy. I paid about $40 for 100 foot cord. I didn’t want to use more than one extension cord so the cords would not pull apart. The hook on the handle for looping the cord to keep it from disconnecting works perfectly. (I once used some hedge trimmers that were a constant headache because the plug would pull out repeatedly.) I thought the extension cord would make the job pretty difficult, but it really didn’t. You just learn to work in patterns that keep the cord out of the way. -- The bag is useless because it fills up in just a few minutes. My advice: Remove it. This machine had enough power that it never got bogged down. But in areas where the grass was a bit high, it was harder to keep it moving through the grass. (Otherwise, it was very easy.) It was easy to switch the dethatcher blade and scarifying blade. I scarified to rough up the ground for reseeding. Before I bought the Greenworks dethatcher, I tried dethatching with a hand rake. Even though it was a well-designed dethatching rake, I soon realized that if I did the whole yard it would take a very long time and leave my old back aching probably for years. So I bought the Greenworks dethatcher. The price was very reasonable. I doubt I could have rented a dethatcher for less. No negatives. (There is a battery version of this dethatcher, but it costs about three times as much.)

I bought this last year because, after 29 years, my lawn was in serious need of a geed dethatcher. Normally, I wouldn't even consider a corded or battery electric piece of outdoor power equipment, but since this is something I'll use maybe onve a year, and I have a small yard, I decided to give this a try. Even though my yard is small, there are parts of it that are way too away from an outlet to use a cord. So, I ended up using a portable generator to operate it. But, I already had the generator, and already maintain it, so this wasn't an additional expense. Regardless, it does a really good job of dethatching. I've not tried the scarifier blades, but after using the dethatcher blades, I initially thought I was too aggressive and removed too much, but by early June, my lawn looked better than when it was brand new. It's not the simplest of setups for my application, but it works great and all things considered, id call it a simple and economical solution for a homeowner that uses it once or twice a year.

Full transparency I almost didn't buy this product after reading some of the reviews about motors burning up, etc, etc. Unfortunately, last year's drought was terrible on my lawn it definitely needed help. After thinking it over for awhile I decided to give it a try out and see how it did. Standard disclaimer applies: Individual results may vary. From the top: 1) The product arrived in great shape and assembly was very simple. 2) I didn't bother to do any engineering calculations on current draw vs length of extension cord, etc. 3) I plugged it in to my 20 year old, 100 foot extension cord and it worked just fine. Pros Worked like a champ, de-thatched and scarified my lawn very nicely, completely pleased the job it did. Lightweight and easy to move around and use. I had no trouble with power supply and motor didn't burn up, but I suspect some situational awareness and common sense should be applied. As with gas lawnmowers it will lug down when the clippings accumulate under it. When it happened I would raise the front wheels and pull it backwards to clear the clippings. I used it for 2 hours on my front lawn with no difficulty. It's very simple to change from the dethatch blade to the scarifier blade with the hex key that is supplied it also has a holder that attaches to the handle to keep the hex key close by. Cons The controls seem to work backwards from every lawnmower I've owned since all the safety devices were installed. You have to depress the start button and then pull the "deadman" handle to get it to run unlike my lawnmower. Not a big thing but part of the learning curve. The poor reviews about the bag were correct it will fill up about 1/3 of the way and then needs to be dumped that equates to about 20 feet of dethatching. I removed the bag and raked.....a lot, but it ended up being faster than using the bag. This is why I gave it a overall 4 star rating. Overall I'm happy with my purchase and it did a great job of getting my lawn prepared for another Texas summer.

Worked well for de thatching. I have a small yard and one charge did it all. Light and easy to use. Great quality for the price.

Works great! Only bad part is the bag is small so we have to empty a lot but its not a big deal. Great quality and helps so much with grass growth.

My neighbor has one, let me use his a couple years ago, decided to get my own. I have a section of Zoysia grass on my side yard, VERY THICK, plush grass that needed dethatching. This works great! Easy to use and maneuver. Suggest getting a 75-100ft outdoor extension cord for it.
