Greenworks 40v Mower

Took about 5 minutes to have it ready to run out of the box. Mowed taller grass under my solar panels with ease. Run time about 45 continous minutes. Bought extra 8ah battery but really didn't need it. Super easy to adjust cut height. Also got trimmer to go with it. Would definitely buy again

Love this mower so much I bought it again!

[This review was collected as part of a promotion.] Replacing one I bought 10 years ago, and worked to death. A great mower.

Georgia Zoysia

I have been very pleased with the cutting power of the G-Max. It cuts through my Zoysia grass as easily as blue grass on the lowest height setting. My yard is about 7000 sq. feet and on a hill. I can mow it twice before charging the batteries which is surprising with this thick grass. I use the bagging system and am very impressed with the clean look after I am complete. The deck will get so close to the mailbox and fence I literally do not have to weed eat afterwards saving me time and money, and not lugging gas cans to the station is a huge plus. No more leaving the windows down in the car to get the smell out. I highly recommend the G-MAX.
