    • Easy to use

Very nice lawn mower for medium to small yards. I found it to be very easy to operate easy to charge and just a great lawn mower.

    • Battery completely dead after a couple uses ** Updated **
Size: 21" Mower
** UPDATE ** Support finally reached out to me once I was able to enter their callback queue. After giving them all of the information, they are mailing me a new battery. I'm happy for the resolution, but the effort put into simply getting in contact with anyone was a bit problematic. Hopefully I do not have to deal with this issue again in the future. Original review below -------------------------------------------- Mower is great. However the 5ah battery which came with it is completely dead. It will not charge nor display any charge indicators. I have several other Greenworks tools and batteries. All other batteries charge and work as they should, even on the charger this battery came with. I've tried contacting support. Sat on hold, requested callback, tried to use online chat (which is just a bot and then times you out when you ask for a support agent). So far cannot contact Greenworks in any way to request support. Battery and mower are way less than a year old, and only a couple of uses. If this is how warranty and support issues are going to go, then I will shop with a different brand from now on, because this is not acceptable. ... show more

    • Decent mower
Size: 21" Mower
Good stand up storage solution. Cuts grass decently, but note that it is less battery efficient than the old two motor Greenworks mower. A 4 amp hour mow with the two motor model may take 5 amp hours with this one. Also it's more of a workout to push up hills than the old two motor mower. I'm assuming it's a bit heavier, but I haven't verified that. ... show more

    • Amazingly capable, convenient
Size: 21" Mower
I started with a 14" push power from Greenworks, dipping my toes in cautiously on an open box bargain to see how it went. It went much better than expected, so I upgraded to this unit and I'm very pleased with it. Other than the obvious cutting width difference, let me tell you some of the functionality improvements on this one compared to the 14" -It holds two batteries-- doesn't auto switch, but much more convenient than having to run back or carry one with you -It will store upright with a convenient pull of a couple tabs on the handle -It has a "full width" handle to keep the unit running while pushing. This was critical for me. I have some right hand issues and needed to be able to "share" that duty and the 14" has a handle only on the right side to keep it running. This was a big relief for me and improvement over the 14". -It has a much more reliable deck raise/lower mechanism than the 14". The 14" with heavier use would pop off some plastic piece under the deck meant to raise/lower it. If you pushed into some heavier material to mow it could pop the 14" down a deck level or few. This one has that mechanism in the back, so these problems aren't faced. This mower is very capable, and far lighter than a gas motor equivalent. I don't even need or miss self propel feature because it's so light and easy to maneuver. Fully satisfied and fully recommended. You won't regret it. Promise. ... show more

Size: 21" Mower
My smaller and older mower went kaput this summer. It was Green Works and I’d had it for a few years. It worked great in my yard and I could mow almost my whole yard in one battery. I have sort of a fair weather yard that tends to pool rainwater a bit so grass grows and often I have to wait a bit to let it dry out. A long mow takes two batteries. With the old mower. I upped my mower with this bigger one but it appears to eat my batteries. I’m not done with my small front yard and I’ve gone thru 2 larger and two smaller batteries. I’m still not finished. I have not gotten to the back yard yet. This mower is much heavier, harder to maneuver. AND is absolutely ineffective in that my batteries lose charge within a few minutes. I have a few green works machines so I have numerous batteries fully charged. Well I did anyway. I regret spending more for this bigger mower. I’m really disappointed with its performance. I also accidentally ran over Nick the snake, so I’m mourning him too. About five years ago I met Nick, who went by Nicolas at the time, while cutting blackberries. I accidentally cut Its tail off. I was mortified of course. The following spring I spotted what appeared to be a full tailed snake, not Nick, in another part of the yard. Moments later Nick too made haste. I was happy to see the two and renamed the pair Nick and Jessica. This year I noticed their point of ingress/egress to the under-well of my home. We’ve a mice arrangement. Nick isn’t a substantial snake but he sounded substantial this morning. And now I have a Jessica snake totally unaware Nicks not returning home tonight. I checked the snake parts and saw the smooth nub of his nick. So it’s definitely Nick. Please take a moment to mourn the loss of the mighty mouser and pest killer Nick. He did a wonderful job. May Jessica forgive me and May she find new love. I’ve only ever seen the two snakes, so i don’t know if there is a pile of teaming orphans Jessica must contend with. It’s all a lot. I’m very sorry for your loss Nick. The tail part 5 years ago and for all the parts you needed to function as designed today. All of the yard mourns you; the crows Mr and Mrs Kim and their soon Tim, the Bunny Bunch, and of course it goes without saying…Mr and Mrs Impossumable. ... show more

    • So easy to use, does a great job, perfect for a smaller yard.

Review Image by Froggee Racine
I love this mower! It cuts and mulches very nicely. Easy to put together. Easy to start. Height adjustments made simply. No gas or electric cords to get in the way. It has a second storage spot in the battery compartment for a spare battery so when the first dies, you can easily swap it out and keep mowing. I have a relatively small yard and the battery does the whole yard plus some for the next mow. I recommend getting a large spare battery to have ready to go. Eco friendly! Not very loud for a mower and easily maneuverable. ... show more

    • Good mower battery dead on arrival
Size: 21" Mower
I have been using battery mowers for over 20 years and a mixture of gas and corded electric before that. This mower performs well. I opted for the steel deck version as it was the most basic overall design. I don't need lights and other bells and whistles. I would however like the option of having the extra battery storage being wired too so that when the primary battery dies the secondary kicks in so you have uninterrupted run time. Battery life is impressive though. The motor has no problem with tall grass the torque is impressive as well. I would definitely recommend buying this mower. It is heavy so if that is a concern you may want to opt for the plastic deck models. I'm giving three stars because out of the box the included battery was defective. It will not take a charge. I have other greenworks batteries and chargers so I was able to use them. I will contact support to see about getting a replacement battery and if that goes well will update my review accordingly. ... show more
