Two batteries rather than one is the whole argument for this Greenworks, and the handoff between them is what we watched for on the first lap: whether the mower stumbles halfway down a row when one pack runs flat. It doesn't. Greenworks rates the pair for up to three-quarters of an acre, and that matches the shape of the machine. A normal suburban lot finishes with charge to spare, and a bigger one gets done without a mid-mow swap.
The drive is where this one earns its keep. Rear-wheel drive puts the push under the weight, and the speed lever adjusts as you walk, so a careful pass along a flowerbed doesn't have to be a careful pass down the whole lawn. At 65 pounds it's light enough to steer with one hand and to stand on end in the corner of a garage. The rear-drive habit takes a session to learn: with the bail held, the drive wheels hold their line, so you release it to pivot at the end of a row and pull the mower back by hand.
Four cutting modes is more than most decks offer, and the turbo setting with leaf pickup is the one we didn't expect to care about. It turns a fall cleanup into a couple of passes instead of an afternoon with a rake. Mulch, bag, and side discharge cover everything else. It's quiet enough that ear protection feels optional, and the four-year coverage extends to the batteries, which is the longest warranty here.
What it asks in return is patience with runtime. Thick, wet spring grass drinks charge faster than the rated figure suggests, so on a long lot in May plan a break and a top-up. From June on, the second battery simply absorbs it.
Bottom line: For a lawn measured in fractions of an acre, this is the mower we point you to: two batteries, four cutting modes, and the longest warranty in the group.
