  • Good quality, self-propelled lawnmower had a reasonable price
This is a great product. It cuts my Saint Augustine grass very well. One thing I would recommend is that you buy a second battery my lawn isn’t that big and I use about half of my second battery, particularly when the grass is long. I have had self-propelled lawnmowers before. Some of them have a speed that is way too fast for me. This one has a great walking speed and even if it’s too fast for some people it easily controllable through the power handle, which is right at your fingertips ... show more

  • Excellent mower.
This mower is the nicest to mow with that I have ever encountered in over 50 years of mowing. At 66, I'm a bit broken down in the back and can't pull start a gas mower or push a mower around the yard This self propelled mower solves both those problems it is a dream to mow with. The only weakness is battery life, which is always the case with any battery powered tool. I already had 4 batteries from green works products and this mower came with a 5 amp hour battery. So with all 5 batteries I can mow a full acre of grass with power left over It has plenty of power for ordinary mowing. Probably not enough for foot long wet grass but plenty for normal mowing. Whisper quiet, no gas, no exhaust, I absolutely love it and highly recommend to anyone. It's also a snap to assemble, no tools needed, just attach the handle and charge the battery and you're ready to go. The included 5 amp hour battery lasts me 20 to 30 minutes. With my 4 spare batteries I could mow continuously for 2 hours or so if I had that much stamina (which I don't). Great, great mower. ... show more

  • Great lawn mower; Disappointing battery
I have been using this lawn mower for about 10 months now. First things first: This is a great lawn mower. Quiet, powerful, sturdy. Switching from a gas mower, the convenience of cordless lawn mower is amazing. I can never go back to gas mowers now. The battery sucks ! The first time I used the lawn mower, it lasted for 50 minutes. Now, it barely lasts for 22 minutes for the same kind of operation. The reduction in battery life has been gradual making me think that it is going to further reduce soon to the point of being useless. That is really sad. ... show more

  • Love it
This is replacing the Greenworks 19" cordless. It is quite a bit heavier, noisier and harder to maneuver for cutting in and doing corners. That said, on the straight cuts, it's brilliant. I have no problem with the self-propel bar except to remember to let go before it takes me into the street. The battery for me is much easier to take out than the nineteen inch. It comes straight up, and if needed two hands can be used. The other had a horizontal extraction on an angle which was difficult for only one old hand to grip and pull out just the right way. It is a powerful machine, and it will use a lot of power. The battery given will not last the complete cut for me with a small yard even if it is a 5.0 AH. I think most people will need a second battery. With two cordless mowers, a cordless blower vac and a cordless snow blower, Greenworks has yet to disappoint me. ... show more

  • Battery Doesn't Last Long Enough and It stopped working after one year.
I mowed only about half of my back yard before the battery gave out. The red light came on -- the manual says that means it's hot and you have to let it set for 30 minutes before you charge it. Then it takes 90 minutes to charge. At this rate I'll never get my yard mowed. It doesn't way 20 some pounds; it weighs 75 pounds. It was easy to get set up and use. The mowing seems fine. That 20 minute battery function is going to be a problem though. Later: Battery lasts only 20 minutes. Then you have to wait for 30 minutes for it to cool off and then 2 hours to recharge. It takes me 4 charges to do my backyard alone -- 12 hours to do a 40 minute job. Another 10 hours to do the front. I just don't think this is going to work for me at all. Huge disappointment. I wonder if I can return it. I can't deal with this all summer. It's a pain. ONE YEAR LATER: I bought this April 2024. Used it until October. Just now went out to use it and it won't start. Nothing. Battery is charged. I can't buy a new lawnmower every year. ... show more
