  • F.A.Q.

Sun Joe AJ801E 12-Amp 13-Inch Electric Dethatcher and Scarifier

The Sun Joe AJ801E Dethatcher is designed for lawn improvement and renovation. When in use, it eliminates dead materials, thatch, and other determinants that can harm the value of your lawn. 

It packs a 12-amp powerful motor that can rake 12.6 inches of grass in one pass. This is an effective backyard tool, especially when used on small to medium-sized lawns. 

For added control, the Sun Joe AJ801E has a 5-position depth control knob. The knob works by allowing you to adjust the raking depth (10mm below – 10mm above soil). This electric rake can aid in gardening because it will give you the depth needed to plant fruit or vegetables afterward. 

Another highlight feature lies in its dual functionality. To explain, the Sun Joe AJ801E can act as a scarifier and a dethatcher. It has two different blades for both parts, which also helps in reseeding the area faster. 

Once the Sun Joe AJ801E comes in contact with the soil, it creates a trench that allows for reseeding. In addition, it will clean up the extra debris that is lying in your backyard or garden. Thus, giving you a cleaner and healthier lawn in the long term. 

However, its only drawback lies in its collection bag. When compared to other dethatchers, it only collects minimal debris or thatch. After a single pass, the bag will need to be emptied, which can be a hassle for users with larger backyards and lawns. 

Its lightweight size is another advantage. The Sun Joe AJ801E is made out of plastic, making it less bulkier than competing brands. Also, it has foldable handles that have compact storage. This also proves why having a dethatcher is necessary for any homeowner. It gives you the ability to fix your lawn within a few days instead of paying for a rental and having to finish it in one go. 

For added safety, the Sun Joe AJ801E has a safety button and an instant start button. The safety button allows the user to instantly turn off the dethatcher in the event of an emergency, while the instant start button quickly turns it on for quick lawn work.

Despite its low price, the Sun Joe AJ801E is a great tool to aid in revitalizing your lawn. It comes with a 2-year warranty, which provides more long-term security and protection of the device. Overall, this is a recommended choice if lawn optimization is your main priority.
