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

This 80V self-propelled mower is built for homeowners who want to cut a mid-sized lawn without the noise, fumes, or maintenance that come with a gas-powered machine. It ships with a 4.0Ah battery and charger, so you are ready to mow from day one. The 21-inch steel deck gives you a wide enough cutting path to work efficiently without making the mower unwieldy on tighter properties.

The brushless motor is the core of what makes this mower worth considering. Brushless designs typically deliver more torque from a smaller package and tend to run more quietly than brushed motors or gas engines. The listing notes the mower is three times quieter than a comparable gas model, which matters if you have neighbors close by or prefer to mow early in the morning. The steel deck adds durability without the rust risk of some lower-cost materials.

Self-propulsion makes a real difference on sloped or uneven ground. The rear-wheel drive system pushes the mower forward, so you guide rather than muscle it. Variable speed control lets you dial in a pace that matches your stride, which reduces fatigue over a longer mowing session. The LED headlights are a practical touch, letting you start before sunrise or finish after sunset without losing visibility.

The main limit to keep in mind is range. The listing says the mower can handle up to half an acre per charge, but it also notes that actual coverage varies based on grass condition and how you operate the mower. Thick or damp grass will draw more power and reduce that range. The listing does not specify the number of cutting height settings or whether the mower offers a mulching or bagging option, so check those details if they matter to your yard routine.

Verdict: This mower suits homeowners with a lawn up to about half an acre who want a quieter, lower-maintenance alternative to gas. It is especially appealing if you already own or plan to buy other Greenworks 80V tools, since the battery works across the entire lineup.
