Product Overview


Let your lawn breathe. Get your lawn in top green shape with the Sun Joe Dethatcher Joe AJ801E 13 in. 12 Amp Electric Scarifier/Lawn Dethatcher with Collection Bag. Powered by a robust 12 amp motor, the Dethatcher Joe rakes a 13 in. wide path in a single pass to get your job done fast. Enhancing its raking ability is AirBoost technology, which maximizes thatch pickup with spring steel tines that stay sharp longer for reliable performance. Use the 5-position depth control knob to tailor the raking depth from -0.4 in. (10 mm below the soil) to 0.4 in. (10 mm above the soil), depending on your lawn's scarifying or dethatching needs. Scarifying your lawn at regular intervals cuts grass roots and encourages growth for thicker, healthier turf.
Thatch is a dense mat of roots, stems and grass clippings that accumulates on lawns over time, blocking the flow of water, oxygen and vital nutrients. It is important to periodically remove thatch in order to keep your lawn green and healthy. While ordinary manual rakes are tiresome to use and not very effective, the electric Dethatcher Joe starts instantly with the push of a button and easily gets the job done without polluting the atmosphere with toxic carbon emissions. No gas, oil or tune-ups make the Sun Joe Dethatcher Joe your green choice for greening your lawn. The machine is ETL approved and backed by a full two-year manufacturer warranty.

Great tool and great warranty service
First of all I want to say the product is very good for the price. I was dubious about a dethatch machine for $100. I have used commercial rental machines several times and they are very rugged all steel machines. So I was concerned that a smallish plastic machine like this would even do the job. But I was surprised that it did a very good job. I used it to dethatch my entire lawn. I had a lawn that was 100% weeds so I killed everything and two weeks later used the sunjoe to dethatch. I went over the lawn twice, north south then east west. Basically cutting slits down into the dirt. The machine is light and easy to move around. While the cord was annoying to deal with it is necessary and just has to be accommodated. It was very convenient to own the machine. I was able to take several different days to do my moderately sized lawn, so I did not have to schedule a rental and try to get it all done in one shot.

It was very easy to put together. Two screws and four knobs was all. Took about 10 minutes. The motor is very powerful. I had no problems with it turning off from overheating. I just bought two 50 foot 12 gauge cords and it worked fine.

I did experience a problem with the gear drive that broke. This was likely because I encountered rocks a few times and I think the rocks stopped the blades. Next time I will be more careful to watch for rocks. I contacted Sun Joe and they were great. Sent me a replacement machine immediately and I packed up the broken one and sent it back. They paid the shipping as one would expect. I am not put off by the broken gear. If I get another season use it is all I expected from a $100 machine. It cost less than what I would have spent on a rental machine.

I recommend this machine to others.

Just wanted to let people know that that it works great on removing the dead grass from the lawn and did everything it said it would. I highly recommend it. The only thing is the bag is small, do I used it without the bag attached. Also it only weighs 33 lbs. and is very easy to use.

I was pleasantly surprised by this little guy. If you have an average sized lawn where the farthest corners can be reached by a 100' extension cord,, then this will do the job. Works like a mower that pretty much self-propels itself, only this machine's path is approximately 12" wide so it'll take a little longer than your average mow.
I've only used it once thus far, but the only thing I see as a potential issue over time is how soft the plastic got. The part used to power the machine on started to feel softer and started to "give" a little more than when I first started to use it. Other than that, it did a great job of digging up thatch.

This is a good machine for the price. I wanted to find a simple machine to dethatch my lawn and found this electric dethatcher. To be honest, I read the reviews and although most users complained about the collection bag being small, I decided to buy it anyway. I found that this machine, due to its size is great for lawns under 5,000 square feet. Anything larger and it becomes a tedious chore. As far as the collection bag size, it is really not useable. I believe the manufacturer made it small to avoid users overheating the electric motor (you have to empty the bag often). I ended up not attaching the bag at all (against the manufacturer's advice) and had my wife follow me with my lawnmower which has a normal size grass catcher. This made the project a little bit easier. Since I will only do this a couple of times a year, this item will do. It beats renting a larger industrial size machine and having to struggle carting it around.

Extremley Pleased with Dethatcher !
This dethatcher was easy to put together. I decided to try it out on my Zoysia grass in a small area and ended up doing my whole lawn in one shot ! It does clog up if you have alot of dead grass ( especially zoysia) but its no problem. Just stop after a few feet and shake it out. I definitley recommend this product

This is a wonderful product. I'm a 60+ year old female (not the strongest) and I thatched the front yard bermuda grass with it, prior to overseeing with winter rye grass. I took off 12 large lawn and leaf garbage bags with this little but mighty thatcher. It worked far beyond my expectations. Lightweight, easy to use. Loaned it to my son in law to try in his back yard. He, too, thought it was a great tool.

For getting soil ready for reseeding this machine works really well for do it your self folks.
I removed, a surprising, 8 trash cans of old grass from my small front yard.
I used the dethatcher first, then the scarifier.
From previous reviews I did not use the catch bag.
Down to mostly bare ground.
The new grass seed must have liked the preparation.
Planted seed and put starter fertilizer with it September 27 2018.
Mowed plush new fescue lawn October 29 2018.

Used 12 gauge 100 ft cord. Sun Joe had plenty of power to get 'er done !
Customer service is outstanding.

Each and every year I would spend hrs raking the thatch in my lawn and never have I finished raking the entire lawn. But this year I was done raking the entire lawn in about a day using this amazing product from SunJoe. Heading to the advice of many of the reviewers, I did not use the collection bag. Assembling this unit was a breeze. A couple of my neighbors had stopped by and inquired about this product. I told them that this is worth the buy and is a very good investment. In spring I plan to use the scarifier.
