Rated 5 out of 5 by from Great product! I was hesitant to make the switch from a gas mower for fear of the battery dying halfway through my yard. The first mow it had been about a month since I mowed and it powered through with 1 bar to spare. Since then I've mowed once a week (3 times now) and have not had to charge the battery, seems to only use a bar per mow as long as the grass is low. It's light and super quiet, easy to start and the stand up storage is awesome. Looking for a trimmer to pair with the mower that runs on the same battery.

Rated 4 out of 5 by from It works for me... I bought this mower to mow some small areas that I normally weed eat. With the mulching door closed it mows these areas very well and leaves no mess to worry about. As advertised, it doesn't like wet grass so I make sure it is good and dry. It is quiet and plenty strong enough. As a bonus I don't have grass stuck to my pants, shirt, boots and glasses, and no bruises or cuts from sticks and rocks from the weed eater.

Rated 4 out of 5 by from Good Value This particular mower was apparently packaged for sale at Wal Mart as it had permanent Wal Mart barcodes on the box (no problem there). What is odd is the battery is clearly a G-Max battery however it has no such markings. I have since bought two other tools that require the 40V G-Max battery and the battery works fine in them. I found the battery life to be excellent much better than many of the reviews indicated. It is quiet and easy to use. The only con is the quality of the bagger and the chute both of which are pretty cheesy.

Rated 2 out of 5 by from The battery life is a joke. Just bought this and was excited to mow my yard but a 30 minute job has turned into 5 or more hours. The battery life is a joke, im only get at most 15 on a full charge. I think I'll be packing this back up and getting a gas one. Tried to think about the environment but I can't even finish my front yard on two full charges? What good is that. If you have like zero to no yard go for it, but other wise there is zero convenience and a lot of waiting for the batteries to charge!

Rated 4 out of 5 by from LOVE! I've nicknamed my mower Megatron and absolutely love it! The only drawback is the battery. I have a decent size yard not too big not too small, but I had to stop halfway through the backyard to charge the battery. I know I can get another battery, but it's not in the budget right now. Perhaps you should offer a package to purchase that has two 4Ah batteries. The mower itself was extremely easy to put together out of the box and so incredibly light to push and maneuver! I would certainly recommend this mower. Now granted I've only done my backyard, but other than the battery I am thoroughly satisfied. I can't wait to try my trimmer (after the front yard and a few more charges I'm sure). If you're on the fence, get off the fence and buy this thing! It's even more fun if you have matching socks and sneakers! (I couldn't put the picture, apparently it's too large)

Rated 5 out of 5 by from Fantastic!!! It's a joy to mow my lawn now! This mower is super easy to use and does a great job. I mowed my front and back yards (20 minutes total) and still had enough battery left to mow it all again.

Rated 4 out of 5 by from Very good mower. Mower has cut through thick Bermuda well. The blade sounds like it ramps up slower than the 2 motor greenworks 40v mower system, but does a good job and seems to more consistently cut the full 20” wide path. I’m torn on the steel deck. It keeps the mower body down better than the plastic deck, but I scraped it on a concrete curb which I didn’t work about with the plastic deck.

While using the mower today, there was a period where the motor INCREASED significantly the rpms and of course the cutting performance improved. Is there any adjustment that allows me to use this MAX blade speed? This only happened once. Thank you

Asked by: Gallante
Hello Gallante, A model number of your unit would help us to better advise. If your unit has SmartCut™ technology this feature is automated and cannot be adjusted. SmartCut™ technology which automatically adjusts performance when mower detects changes in cutting conditions. Try disengaging the start, then pulling the unit back on a clear path, and starting it back up again. This may help with the detection. However, again this feature is automated and cannot be manually adjusted.
