Our take on the Greenworks 80 Volt 21-Inch Lawn

The Greenworks 80V 21-Inch is a cordless self-propelled walk-behind mower with a 4.0 Ah battery, a 21-inch deck and a 60-minute charge time. It offers three cutting modes (bag, mulch, side discharge), seven height positions and a folding handle. It suits homeowners with medium to large lawns who want gas-like power without fuel or cords. Against 40V and 60V rivals it cuts wider and pushes harder, but it is heavier and the battery is a large single pack rather than a swappable set. Owners like the torque and the mulch finish; some note the weight and the run time on tall, wet grass.

Owners praise the cutting power and the clean mulch finish, and many say it matches gas mowers on tough lawns. Complaints center on weight, run time on tall wet grass and the long recharge.

Questions and answers

How long does the battery last per charge?
Greenworks rates it at about 60 minutes of run time, and the battery charges in roughly 60 minutes. Tall or wet grass shortens that run time noticeably.
Does it bag, mulch and side discharge?
Yes. It ships with a collection bag and supports mulching and side discharge, so you can switch modes without extra parts.
Is it good on hills?
The self-propelled drive helps on slopes, but the mower is heavy. Steep grades still take effort to control.
How does it compare with a 40V mower?
The 80V system delivers more torque and a wider 21-inch cut, which suits larger lawns. A 40V mower is lighter and easier to store but struggles more in thick grass.
What comes in the box?
The mower, a 4.0 Ah 80V battery, a charger and a grass collection bag. Side discharge and mulch plugs are included with the deck.
Is the handle easy to store?
Yes. The handle folds for upright storage, though the deck itself is large and needs floor space.
Where is the Greenworks 80 Volt 21-Inch Lawn cheapest?
At Best Buy, for $349.99, as of our latest check.
