Greenworks 80V 21in Self-Propelled Lawn Mower, 4.0 Ah Battery and Charger

The Greenworks 80V 21-inch self-propelled lawn mower is a cordless electric mower designed for homeowners caring for medium-sized yards up to a half-acre. Powered by an 80V system with an included 4.0Ah battery and charger, it eliminates the need for gas while offering self-propelled rear wheel drive to ease the effort of pushing across your lawn.

Built around a 21-inch steel deck, this mower houses a brushless motor that delivers extra torque while running three times quieter than traditional gas-powered mowers. The rear wheel drive system includes variable speed control, allowing you to adjust the speed to match your pace and maintain traction across different lawn terrain.

For added convenience during early morning or late evening tasks, integrated high-visibility LED lights illuminate the path ahead. The included 4.0Ah battery is also compatible with over 75 other Greenworks 80V tools, such as trimmers, blowers, and chainsaws. Long-term ownership is supported by a 4-year limited warranty covering both the tool and the battery.

While the mower can cover up to a half-acre per charge, actual run time varies depending on grass conditions and operator technique. High or dense grass may reduce total coverage per charge, meaning larger properties might require pauses to recharge or a second battery. Additionally, the listing does not specify multiple height adjustment positions or grass collection bag specifications.

Verdict: This cordless mower is a practical choice for homeowners with lawns up to a half-acre who want self-propelled drive without gas engine noise and maintenance. Its LED headlights, steel deck, and 80V battery system fit seamlessly into an expanded cordless yard toolkit.
