- 21-Inch Mowing Path: A full-width steel deck ensures efficient cutting over wider areas, minimizing passes.
- Rear Wheel Drive and Variable Speed: With the Greenworks 40V system, users benefit from maximum traction and a comfortable walk-behind mower experience, even on slopes.

Real-World Performance Testing
When we put the cordless mower through its paces, it consistently delivered a high-quality cut in thick and tall grass. This performance is thanks to the brushless lawn mower motor and a potent lawn mower battery that offers up to 45 minutes of runtime on a single charge.
We tested this product on both level yards and moderate slopes. Its rear wheel drive and variable speed functions gave outstanding control, while the 4-in-1 system—including mulching and bagging—made cleanup a breeze. The self-propelled feature acted like a “golf cart” on hills, with users reporting it glides over uneven terrain without strain.

Limitations are few, but keep in mind that for over 1/3-acre lots, you may want an extra battery for continuous mowing. Some users note the need to slightly raise the cutting height for extra-long grass. Overall, the cordless mower provides an impressive, low-upkeep mowing experience for most homeowners.
How It Compares to Alternatives
This model outperforms most competing walk-behind mower options in its class. Compared to popular alternatives like the EGO Power+ 21″ Select Cut and Ryobi 40V HP Brushless, the Greenworks option features a faster charger and a wider variety of compatible tools in its lineup.
In terms of price, it often lands more affordably than EGO and comes with a three-year warranty on both tool and battery. The included LED headlight mower feature and variable speed drive are notable advantages when compared to similarly priced battery lawnmower products.

Who Should Buy This Product?
This tool is ideal for homeowners with yards up to about 1/3 acre who want a low-maintenance, eco-friendly upgrade from gas. If you’re a tech enthusiast seeking compatibility with a 75+ tool ecosystem—including trimmers and chainsaws—this model delivers.
Urban and suburban users will benefit from the quiet operation, especially early or late in the day. However, if you mow multiple acres or require extremely long runtime, a commercial-grade gas mower may still suit your needs. For cleaning up after yardwork, see our robot vacuum recommendations.
