This is a 21-inch cordless walk-behind mower from Greenworks' 40V line, with self-propulsion and a brushless motor the brand claims delivers twice the torque of its standard motors. It cuts up to about a third of an acre on the included 5.0Ah battery, runs up to 50 minutes, and recharges in roughly 150 minutes. It offers mulch, bag and side discharge, and the handles fold to save storage space. It suits homeowners with small to mid-size lawns who want gas-like push-free mowing without fuel or cords; rivals in the 40V class typically match the 21-inch deck but often cost more for the same runtime, and the shared 40V battery works across 75+ Greenworks tools.

It works as a 3-in-1 mower, so you can mulch, bag or use side discharge. The handles fold to take up to 70% less space for storage. The mower runs on any Greenworks 40V battery, which also powers more than 75 other tools. The 40V 8Ah battery does not allow the battery cover to close.
