Our take on the Greenworks 82V 21-inch

The Greenworks 82V 21-inch is a self-propelled walk-behind cordless mower with a 21-inch rotary deck, built on Greenworks' 82V commercial-grade battery platform. It is aimed at larger suburban lawns, with coverage rated around 0.8 acre per charge. Its main draw is gas-like cutting power without gas, oil changes or pull cords, and it competes with other high-voltage self-propelled cordless mowers on torque and deck size rather than on light weight. Owners tend to like the power and the self-propel drive; the usual complaints are weight and battery cost.

Questions and answers

How big a lawn can it mow on one charge?
Greenworks rates coverage at about 0.8 acre. Real-world runtime depends on grass height, wetness and how much the self-propel is used, so thick or wet lawns will fall short of that.
Is it a good replacement for a gas mower?
Yes, for most suburban lawns. The 82V motor gives gas-like torque and the 21-inch self-propelled deck matches typical gas mowers, without gas, oil or pull starts.
Does it come with a battery and charger?
That depends on the kit you choose. Some versions include an 82V battery and charger, while tool-only versions do not, so check the kit before buying.
Can it mulch and bag?
Yes. It is a 3-in-1 mower with mulching, side discharge and rear bagging, so you can pick the mode that suits the lawn.
Do the batteries work with other Greenworks tools?
Yes. The 82V battery fits other Greenworks 82V products, including trimmers, blowers and chainsaws, which spreads the battery cost across your tools.
Is it hard to push up a hill?
The self-propel drive does most of the work on slopes. The mower itself is heavy, so turning and maneuvering at the top of a hill still takes some effort.
Where is the Greenworks 82V 21-inch cheapest?
