    • Easy set up
Size: 21" SP Mower (2x5.0Ah)
Mower works well on small pretty level lot. Battery life is about 30 minutes at a steady pace. If lawn is high or wet will need multiple passes and will have to be recharged. It serves my needs well

    • first electric mower
Size: 21" SP Mower (2x5.0Ah)
just purchased this mower to see how an electric mower worked. My first time with this too by the way. Overall not bad. Just insert the 2 batteries and push a button. The mower is about half as quiet compared to gas mower. It mowed the grass just as good as a gas mower. Easy to fold it up and lean against the wall if you need more space. Its easy to raise or lower the mower for grass height. The self propeller works good too. There is no gas, oil or carboretor to mess with. Now the negatives. I fully charged the batteries first then mowed and it lasted for 30minutes. I had it on lowest setting for the grass height and did not use the self propel option just to see how long it would last. I had to wait 2 hours to charge again then finish my yard. This was annoying. The light on the front of the mower comes on by default and you cannot turn it off. It states that this does not drain the battery but who mows in the dark. This is a strange option regardless. Anyways, I purchased 2 more batteries online and will update after I try those out. ... show more

    • Great mower, my 2nd!
Size: 21" SP Mower (2x5.0Ah)
Mower works great! I started mowing almost right after it was delivered! My only complaint is that Greenworks should construct better fasteners/screws for attaching the top of the handle to the bottom part of the handle. These do not want to grab and secure. I had to keep turning and turning until it finally grabbed and took hold! ... show more

    • Easy to use
Size: 21" SP Mower (2x5.0Ah)
Was easy to assemble basically just the handle. And I mowed our front yard with bagger attachment. Worked great so happy no more messy gas oil mix spark plug or air filter. Just put the battery packs in and go. So happy and what a great price

    • Self propelling terrible, batteries terrible, cuts terribly
Size: 21" SP Mower (2x5.0Ah)
I bought this at the beginning of the summer. I've never had an electric/battery lawn mower before and it has been a learning curve. I needed a self propelled lawn mower. There is a switch for the speed. Turn the switch one way and it pulls the mower out of your hands. Turn the switch the other way and it will take all day to mow a small lawn. I learned that if you slightly move the switch it will alter the speed (but not slightly). If I accidently hit the switch, it takes a lot of time readjusting the speed. If you simply release the self propel lever, the wheels are locked. You must push for a couple of feet after releasing for the wheels to roll freely thereafter. When cutting, it leaves the left side of the cutting path much taller than the right. I often have to cut the my yard twice. The second time about a foot to the right of the original cutting path. The Batteries (this could take a while) I have a small front yard about 40x40 and a small back yard about 60x20. I can not cut them on the same day. I actually cut the most visible section of my front yard in fear that the battery won't last before I finish. I can not depend on the batteries recharging when I plug them into the charger. I plug them in several times to make sure the fan in the charger starts. When it died on my today, I'm pretty sure that one battery had charged and the other had not. I can't imagine why anyone would give this POS 5 stars. ... show more

    • Very good
Size: 21" SP Mower (2x5.0Ah)
So this is a 48v electric lawn mower but it uses and comes with 2x of the 24v batteries that are standard use for the majority of their electric hand tools, of which, I have a good amount of, since I work in Renovation. They're the upper tier batteries, too; a couple of 5.0ah USB battery packs. Also the nice dual charger dock. So that's sick, definitely will be getting plenty of use otherwise. As far as the actual lawn mower's performance, it works really well. Cuts nice and wide, it's well powered and doesn't stall easily, the propulsion is great for hills, the height adjusting is easy. It's great, a good lawn mower. ... show more

    • Mows ok, drives poorly
Size: 21" SP Mower (2x5.0Ah)
I've been mowing with this mower for 2 months now, with pros & cons: Pros: - Quiet enough I'm not worried about annoying my neighbors - Simple plug & play battery packs, no need to keep hot cans of gas around the garage - Mows acceptably even with some tall-ish grass (keeping up on it mostly weekly) Cons: - Drive engages ~2 seconds after you squeeze the drive handle. This is annoying when using it in smaller areas as by the time it engages I've been pushing it most of the way. I've stopped using it unless I'm walking straight ahead for 15+ paces. - Drive locks wheels briefly after you disengage. IE when you want to pull back/turn, you have to give it a few seconds or rock it back and forward again before the back drive wheels will turn when pushing manually. With the slow engagement, it means I'm pushing for a few steps, driving a long stretch and then release a few seconds before I get to a corner. - Drive gets really slow about 1/2 way through a mow. The above things seem to be simple drive switch design issues but a slowing drive seems more like a limitation of the power source. 48v lets me mow 1/2 my 1/3 acre property at a time. I can get more than 1/2 but not a full property mow without recharging. In addition, the drive works at a reasonable pace for about 1/2 of each mowing session, after which I just push it. Conclusion: I'll keep it as I'm not keen on going back to gas mower fumes in my hot garage (no shed), and I've got the complementary cordless trimmer and blower now--but this mower is not a star performer for converting people to electric mowing. ... show more
