Greenworks 13 Amp 14-Inch Corded Dethatcher / Scarifier, DT13B00

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.)

Love it! This is lightweight and works well. We take the grass catcher off and just let the dead grass trail behind, then follow up with a lawnmower/bagger. Really has made a big difference in our lawn. So much cheaper than hiring it done and really easy to use.

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.

Just used this for the first time. Early April in Wisconsin. Put it on setting 1 to clean up the dead grass from the winter and fluff everything up from being matted down under snow all winter. It did an amazing job. So much better than those dethatching units attached to riding lawn mowers - those things would rip the heck out of yard and it would take a month to recover. With this unit it does the work of getting up all the dead grass without ripping it up. This again was at level 1. Absolutely perfect. For the record- I have about 11,000 sq ft of grass and it took about 90 minutes of running the machine and another 1.5 to 2 hours to rake and bag the grass. But now my lawn is ready to go for Spring and looks 100% better.

This thing is amazing! Does a great job, super easy to use - would highly recommend. The same price to have someone come and do it for you, but now I have it and can share it with friends who also want to dethatch their yard.

Es muy buena, escarifica y recolecta en su bolsa… el único detalle es que se llena muy rápido, solo hay que vaciarla constante. Buena compra.

Great machine. Save me a lot work. Amazing.

Excelente atención

Not bad, did a pretty good job dethatching. I only wish the bag was bigger. I was emptying the bag ever 30 seconds of run time, so I did the rest of the grass with it off. Grass was a little wet when I did it and still worked.
