Greenworks 80V 21" Brushless Cordless (Self-Propelled) Lawn Mower (75+ Compatible Tools), 4.0Ah Battery and 60 Minute Rapid Charger Included

The Greenworks 80V 21 Inch Brushless Cordless Lawn Mower provides a clean, battery-powered alternative for homeowners looking to trim large yard areas quickly. Powered by an 80V battery system, this self-propelled mower eliminates the hassle of buying gas, changing oil, pulling starter cords, or dealing with exhaust emissions. It is designed for homeowners who want the cutting force of a conventional mower combined with instant push-button starting and quiet operation.

At the core of the machine is a durable 21 inch steel deck powered by a brushless motor that delivers high torque and long engine life. The self-propelled system uses rear wheel drive with variable speed control, giving you full control over traction and speed across flat or sloped terrain. Additionally, integrated SmartCut technology monitors the condition of your grass and automatically adapts motor power to deliver a consistent, clean cut without wasting battery energy.

Convenience features extend throughout the design. A single lever lets you easily adjust the deck across 7 height positions to suit seasonal growing conditions. You can also handle clippings according to your preference using the 3-in-1 system, which supports mulching, rear bagging, or side discharge. When you finish mowing, the mower can be stored vertically, which uses up to 70 percent less floor space in your garage or shed.

There are a few practical trade-offs to keep in mind before buying. The included 4.0Ah battery provides up to 45 minutes of run-time on a full charge, but actual duration depends heavily on grass conditions and your operating speed. If you have a particularly large yard or tall, dense grass, you may need to recharge using the included 60-minute rapid charger mid-job or purchase a secondary battery from the compatible 75+ tool lineup.

Verdict: The Greenworks 80V 21 Inch Mower is an ideal pick for homeowners wanting high-powered lawn care without gas maintenance hassles. Its self-propelled drive, adaptable cut settings, rapid charging, and compact vertical storage make maintaining your yard efficient and easy.
