My "lawn" is a mix of native ground covers, bunch grasses, fallen leaves, and the occasional twig, on uneven ground. This mower powered its way through the rough stuff as well as my old gas mower, and I appreciated the way the blade speed varied according to the challenge. After whacking down 1/2 acre, I still had about 25% charge left, and the battery fully recharged before I finished my lunch break. If you are joining the anti-lawn movement, this is your tool for mulching and controlling open spaces.
I got tired of replacing carburetors every year, so I researched cordless electric mowers. The reviews consistently pointed to Greenworks as being the best. The no risk guarantee sold me, so I ordered online. I have about 1/4 acre of lawn to mow, with a lot of maneuvering around flower beds. I received it from the company about four days after I ordered it. Assembly was minimal, and did not require special tools or "another set of hands."
The batteries came partially charged, so I decided to go ahead and give it a try. My previous mower had been self-propelled and battery start, and was a real chore, because the self-propelled feature would just leave the wheels spinning in the grass. The 21" Greenworks was a dream to push. It is so lightweight that it took no effort to get it around the yard. Even starting with the partially charged battery, I had plenty of juice to get the lawn mowed. It cut evenly , even on my irregular lawn. The battery charges quickly, so I was able to get enough power for my trimmer as well.
I love the fact that I can adjust the wheel height of all four wheels with one lever, and it is a smooth operation to raise and lower them.
I really bought it for the battery to give my chain saw extra run time, I thought it was self propelled but it's not. However the light weight & large wheels make it reasonably easy for a 62 year old to push if you're smart & mow the most level direction rather than going around in circles. The biggest surprise was that it mulches better than it side discharges, especially surprising since I am not an enthusiastic mower & the grass get's very tall sometimes. I like that it's very light with the battery out & is east to flip over & clean thoroughly when finished - I just store it in a spare room between mows. I still wish I had self propelled but this one works well for what it is. As for the battery - it works in the chain saw but makes it quite heavy.
