Sun Joe AJ805E 15-Inch 13-Amp Electric Dethatcher and Scarifier w/Removeable 13.2-Gal Collection Bag, 5-Position Height Adjustment, Airboost Technology Increases Lawn Health, Green | and Collection Bag - 13-Amp Corded Yard Power Rake Tool Machine for Grass Thatch Removal, Electric Powered

Assembling the handle is all that is required to get you up and running. I was skeptical till I first used this machine, it is incredible how much thatch it removed even after I had manually raked my lawn prior to me purchasing this machine. Switching from dethatcher to scarifier is simple, flip over machine, removed fastener bolts and switch implements. The removeable collection bag is a joke WAY TOO SMALL, fills up in less then a minute, tried using it once and only once. I rigged up the discharge door so it is partially open to deflect and to discharge the thatch down and behind the machine, if you leave it closed the thatch will bung up under the machine. If you leave the discharge door fully open your legs will be pelted with thatch and debris discharged by the machine at high speeds-and it hurts. I use heavy duty 10 gauge extension cord and have not had any issues, I have read reports of people using light duty extension cords and the motors overheating and burning out. Storage is easy, handle folds similar to a lawnmower, because of its light weight I just hang mine on the wall of my shed in the back yard. This past summer my lawn was the greenest and fullest it has ever been and people complimented me on that. Spring will be here soon, time for dethatching-second summer, so far I highly recommend this product.

All the video reviews I watched were absolutely right: the Sun Joe 15-Inch Electric Powered Lawn Dethatcher is the perfect tool for the job. I was a bit skeptical about whether a corded electric machine could handle my yard, but the 13-amp motor didn't hesitate for a second, ripping up an unbelievable amount of dead grass, moss, and compacted thatch on the very first pass. The 15-inch path covers ground quickly, and the adjustable depth control allowed me to tune it perfectly so it cleared out the debris without tearing up my healthy turf. As most reviewers noted, you definitely want to leave the laughably small collection bag off and just use your lawnmower to scoop up the aftermath, but otherwise, this powerhouse completely saved my back and transformed my lawn. The unit was strong and never bogged down. Plus I could not get over how easy it was to assemble. Best purchase for my lawn I have ever made.

THIS ITEM IS EXACTLY AS DESCRIBED AND WORKS GREAT.

Works great BUT came with a broken ejector flap - the part is plastic. Look online and you'll see that a lot of people either received it broken like I did or it breaks soon after use. It can be fixed with a bolt. Though I'll probably 3D print something up. Sunjoe's quality control is garbage. I would avoid the brand. Update 04/22/2026 After reaching out to Sun Joe directly about the issue I had one of the best customer service experiences you could ask for. They quickly identified what the issue was (sent them a picture), ensured my purchase and then they simply resolved the issue. The dethatcher/scarifier itself is awesome. I have not dethatched my front lawn in 10 years or more. The dethatcher removed over 10 full lawn/leaf bags full of dead grass. The lawn looks pretty bad right after but after a few days of watering it looks better than it did before. I also scarified and then over seeded. In 4 - 5 weeks I will see if the work paid off. Thank you the awesome support Sun Joe!!!

This dethatcher does a solid job pulling up thatch and helping refresh the lawn. Switching between the dethatcher and scarifier attachments is straightforward, but the collection bag fills quickly and works best on smaller areas. Overall, it's a good tool that delivers nice results with a little extra cleanup afterward.
