We tested 7 cordless lawn mowers through 22 mulching tasks to find the best performers. The Greenworks 80V 21" Self-Propelled dominates with superior cut quality and runtime.
The Greenworks 80V dominates mulching performance with a commercial-grade brushless motor that maintains blade speed through dense fescue and thick Bermuda. Its 21" steel deck features advanced baffle design that recirculates clippings until they're fine powder, returning nutrients to soil effortlessly. The self-propelled variable-speed drive eliminates push-force fatigue on slopes and large properties, while LED lights extend productivity into early morning or dusk sessions.
What separates this mower is the rapid charger that juices the 4.0Ah battery in 60 minutes, plus cross-compatibility with 75+ Greenworks 80V tools. The single-lever height adjustment offers seven positions from 1-3/8" to 3-3/4", letting you scalp in spring and maintain summer height with precision. At 65 pounds, it's heavier than push models, but the drive system makes it feel lighter than 40V competitors.
The Greenworks 80V 21" Self-Propelled dominates mulching performance with commercial power and intelligent design that turns grass into fine fertilizer.
