Very nice product. I got the 6 amp battery. and I’m glad I did. It does my somewhat bigger than other in- city yard with about 1/2 left. Very light and easy to move around. I did not get self propelled and am glad I didn’t. Very quiet. Plenty of power and battery life for normal mowing. Even works on damp grass. I’ve read a review or two in which the reviewer said the mower seemed cheap. I disagree. It is lightweight, made of plastic. Heavy is not better for an electric mower.

This is a very good mower for small to mid-sized lawns...you'll need an extra battery...maybe buy another tool...works very well and is rugged....even with the expense of an extra battery this is still a very good deal.

I purchased the GreenWorks push mower because my five year old Earthwise push mower’s battery was dead and I couldn’t purchase a replacement battery anymore. Unfortunately that is one of the cons in purchasing these types of items - you are stuck with their batteries and once they stop manufacturing the batteries, you are stuck with a mower that you can’t use. Now there are some PROS to this mower that I really like - it cuts fantastically, is very lightweight and I mowed a lot of ground before the battery went dead. Now the CONS - the mower is bigger than what I expected. My old Earthwise mower was a 19 inch mower and it was very compact even if the battery was almost the size of a car battery. I could get in between bushes with no problem. With the GreenWorks mower, I’m often afraid I’m going to break the plastic while trying to get in between bushes. Also, even though I charged the battery over night, I felt that the battery did not last very long compared to my old Earthwise. Also, there is no way to check the remaining charge of the battery unless you stop the mower, open the battery compartment and push the button. On the Earthwise mower, all you needed to do is look at the rear of the mower and the indicator lights were right there! All in all I like the mower. I feel it mows very well, is light weight enough for a small female to push it and it was very easy to assemble out of the box. I don’t think it holds up well as far as the battery charge to mow more than my old Earthwise and I really think the price was a bit pricy! My old Earthwise only cost me $129 five years ago. When you look at how gas fell negatively and is now back on the rise, I’m not going to complain because I don’t have to deal with the smell, the mess, the price of gas or the loud noise a gas powered mower makes. Oh, one thing I also want to rave about - the mowing width is wonderful and where it took almost 40 minutes to cut my front lawn, only now takes me about 15 minutes! Who can complain about that !

This pricey mower arrived damaged - the front axle was bent, and the front right wheel was crammed up against the mower body. Amazon had no interest in paying for return shipping, so offered me a partial refund to pay for repair. Not a great solution for a new mower. We haggled over the size of the refund, and eventually I was satisfied I wasn’t getting hosed. I have since detached and bent the axle to the point where the mower is operable. All that said, it’s a great mower. I love the ability to stow the mower vertically. The mower is powerful and can handle my relatively small yard with less than half of the 6ah battery. One nice feature is that when the mower senses particularly dense or tall grass, it increases the amount of power to the motor temporarily. Makes mowing my admittedly diverse yard much easier. One lame feature is the “double battery” compartment. I didn’t completely understand, but the second battery well is just a plastic slot. Sort of a silly feature. I imagine it might be useful if you were mowing a large property and couldn’t easily stroll to your shed or charger, but at that point you probably have a gas riding mower. For $400, this is a high quality electric mower, but maybe a little pricey. Remember that if you order at amazon, it’s a big heavy headache to return - Amazon will try its hardest to not pay the return shipping.

I don’t know what mower everybody else is reviewing on this mower, but I love this mower!!! All those that said removing battery is difficult is wrong wrong wrong. Super easy to remove and place, and the extra holder for second battery is completely fantastic! The battery power? I thought really great! This is not a drill or flashlight your are powering! It’s a 21 inch mower for crying out loud. If you have suburb size lawn easily do front and back yard with 1 battery. I’m on 8 acres and have to mow about 2. I did at least 1/2-3/4 of and acre with 2 batteries and we are not talking about y’all’s cute little lawn grass. My John Deere mower is shot and I needed something quick to keep up with the grass and although we are a Milwaukee family I love green works for my personal use and have blower, weeder, and even bought the little 16 inch chainsaw that is awesome! This mower super easy to put together, no gas, no oil and cuts perfectly and mowed down some tall and thick grass I thought it would struggle with. Y’all completely ignore the rest and buy this mower!

I bought this for my mom's house (I do her yard). It is nice not having to clean carburetors / change oil / change sparkplugs / trouble shoot issues that come with my gas engine at the house. It is actually replacing a gas engine that was at my mom's. This is pretty light weight, comfortable to use. Battery lasts a long time, I usually cut my mom's small yard twice before charging. My mom's yard is bahia, mine is St. Augustine. I tested it at my house and worked well on the grass, but breezes through the bahia easier. Used 5 times so far. I like it and would buy again.
