Overview
Greenworks has built a strong reputation in the battery-powered outdoor tool space, offering an eco-friendly alternative to gas-powered equipment without sacrificing performance. Their 40V cordless lawn mower is the brand's flagship product — and one of the most recommended battery mowers in its price range. We tested it across a full mowing season on a half-acre lawn.
Key Features
- 40V 4.0Ah battery: Powers the mower through approximately 45 minutes of continuous mowing
- 21-inch cutting deck: Wide enough for medium to large residential lawns
- 7-position height adjustment: 1.5 to 3.75 inch cutting height range
- SmartCut Technology: Senses load and adjusts power automatically
- 3-in-1 system: Mulch, bag, and side discharge in a single machine
- G-MAX 40V battery compatible: Same battery works across 30+ Greenworks tools
What We Love
- Significantly quieter than gas mowers
- No gas, no oil changes — press button and mow
- SmartCut handles thick grass without bogging down
Things to Consider
- Battery runtime may fall short for large lawns over 0.5 acres
- Purchase price is higher than comparable gas mowers
Our Take
The Greenworks 40V cordless mower is the best battery-powered option for homeowners with lawns up to a half acre who want to eliminate gas maintenance and noise. The G-MAX battery ecosystem adds significant long-term value.
