Greenworks 40V (2-In-1) Dethatcher / Scarifier, 5Ah USB Battery and Rapid Charger Included, DT40B510

The Greenworks 40V DT40B510 Dethatcher and Scarifier cleans out lawn thatch and conditions soil for homeowners maintaining cool-season or warm-season grass. It combines two lawn care functions into a single cordless tool powered by an included 5Ah battery.

The machine features quick-swap reels so you can switch between dethatching and scarifying attachments without fuss. Its 14-inch working path clears ground efficiently, while the removable grass collection bag collects pulled-up debris as you work. Five depth positions let you tailor settings from -1/2 inch to +1/5 inch for scarifying, and -1/10 inch to +3/4 inch for dethatching.

Equipped with stainless steel tines, the attachments retain their sharp edges across seasonal treatments. The included 5Ah USB battery charges with the rapid charger, providing cordless freedom across your yard. Timing instructions guide use for early spring or early fall dethatching on cool-season turf, or late spring through early summer after the second mowing for warm-season grass.

While the machine includes a grass collection bag and battery setup, the listing does not state the bag capacity or total runtime per charge. Verdict: The Greenworks DT40B510 is a versatile pick for homeowners who want an adjustable, 2-in-1 cordless yard tool to remove buildup and scarify soil without managing power cords.
