Greatly impressed

[This review was collected as part of a promotion.] This is my first battery lawn mower, and I'm very impressed. The mower handles my centipede grass much better than I thought it would, and the double battery setup finished the whole lawn with charge to spare. I have 1/3 acre. The personal pace self propelled system takes a little getting used to but I really like it. I'm 73 years old with bad knees and I appreciate it.

Good value for the money and very easy assembly.

I have another Greenworks mower that I love. This one is less powerful but good for a rental property and mowing down aspen shoots that have taken over my lawn.!! Super easy assembly but sort of odd configuration to have to push the handle down to engage the auto drive. Just takes some getting used to! It does move along when engaged!! So much better than a gas powered/ oil changing / loud polluting gas mower. The mower is not inexpensive but over the life of it way ahead of a gas mower!! Overall just easier and quiet. I have a relatively small yard so it is perfect! I'm guessing I'll get at least two mowing if not more from the charged batteries. I've used it just once.
