How long does the battery last?

Greenworks rates the included 80V 4.0 Ah battery at up to 45 minutes. Real runtime drops in tall, wet grass or on hilly ground, so a spare battery helps on larger lawns.

Does it come with a battery and charger?

Yes. The kit includes one 80V 4.0 Ah battery and a charger. Check the listing for the exact kit, since bare-tool versions exist.

Can it mulch and bag?

Yes. It bags, mulches and side-discharges, and the 21-inch deck has seven cutting-height positions.

Is it good for a hilly yard?

The self-propelled drive with variable speed helps on slopes. At about 60 lbs it is heavy, so the drive does most of the work.

How does it compare with a gas mower?

It starts with a button and needs no gas, oil or spark plugs. It gives up some runtime and raw power versus gas, so large lawns may need a second battery.
