2x more torque takes the work out of yard work

Powerfully smart. Tackle the toughest yards, one-handed, because our smart mowers never bog down. When grass gets thick, tall, or wet, Greenworks sensors tell our brushless motor to rush power to the mower blades. The end result? The perfect lawn, every time.

Powerfully tough. The deck is forged with heavy-duty steel, ready to tackle any terrain. Add in algorithms and a brushless motor to reach unrivaled blade speed. Ka-pow!

Powerfully easy. Simple to start with just the push of a button. Effortless to mow because it's self-propelled, no sweat! Gentle on the ears because it mows quietly. A cinch to store in small spaces, you can even hang it up if you want to.

Additional features include a 3-in-1 cutting deck lets you choose your cut finish from mulching, bagging or side discharge

Zero gas smell. Zero pull cords. Zero maintenance. Zero pollution breathed. Zero time wasted.
