    • Great, powerful mower.

Bought the 80 v with 4ah battery, self propelled. Super easy to start out of the box, no assembly. Folding handle is a nice feature for storing and especially cleaning. I have a half acre of mixed weeds, mostly grass, some mustard etc. unfortunately I let it get out of control this year, knee high in areas, my riding mower stopped working last year and I dragged my feet choosing this mower. Soooo. It performed great. Lots of power. Stalled twice due to thick grass but so does my riding mower. I developed a technique of tilting back at 45 degrees for high grass then went over it forward and back. Most areas over 8 inches needed mowing back and forth, moving along at six feet at a time, didn't use the self propelled feature at all. The mower is very light. Under six inches no problem at all. The battery lasted about 30 minutes, charged in under an hour . Because of high thick weeds I had to do this five times for my half acre even without using self propel which I presume saved battery life but if mowing grass under six inches (next time!) I expect it would do most of the half acre on a charge. I'm 68 And retired so I didn't mind waiting for the battery to recharge. Definitely recommend. Consider an extra battery. ... show more

    • First impressions, I’m impressed: update
Size: 21" Self-Propelled

Delivered packed and protected well. Assembly was minimal and easy - pull the rubber plugs out of the arms and attach the control bar. I’m comparing this to my nearly 10 year old sears Briggs & Stratton, that still runs. The green works is lighter, has a faster self propel(which is so nice), quieter, and cuts just as well, if not better. I have a patch of grass that grows thicker that bogged it down, does the same to my Briggs & Stratton. When I put it in turbo mode it ran through it fine. It took a minute to get used to the rear wheel self-propel but that’s all. I also appreciate how you can flip it on its end to clean out, much easier than a gas mower. Overall, I’m impressed at how well this cut and how easy it was to maneuver. I cut my front hard and still had 3 bars (my front yard is double from what the picture shows). Hopefully it continues to perform this well. I’ll address my review if it drops in performance. After one mow, 5 stars. Update: I had a few large branches in part of my back yard so the grass and weeds grew pretty tall, calf to knee high. Mower surprisingly did well. Gotta have it on turbo and can’t use self propelled, seems to bog it down with taller grass. But it ran right through it. First thing in the morning and the grass was wet too. Being electric it’s also easy to tip it over and clean the wet grass off. The bag is on the small side, but still happy with it overall. ... show more

    • It's a lawn mower, but you knew that.
Size: 21" Self-Propelled
RTFM - read the fine manual. The pamphlet on how to assemble? Yeah, read the book instead or you'll be trying to figure out how to insert the control bar through the rubber shipping bumpers. Also, you have to hold the start button in and hold the blade start bar within 5 seconds or it won't start. And there's a little safety plug held on by a little string. I hate that. It's gonna get lost and make the machine useless, like my table saw. I'm old (70) , so I set the self propel speed to turtle speed. I can do that. It's a slider, not a switch, so you can pick how fast it goes. Nice. Mowed most of my front lawn and the battery only went down a bar, so life battery good, first day at least. It cuts grass. It doesn't do the dishes or even work as a weed wacker so, yeah. Works well cutting my grass, but it's spring and there wasn't that much to cut. Manual makes the cutting blade sound delicate - have to keep it in balance. Can't abuse it like with a gasoline mower where you can use a dull blade and just bludgeon the grass to death. Bar is just the right height for me... I was 5'10 when I was 16 but I'm shorter now like 5'9. Can't adjust the height of the bar, so I'm lucky it's just right for me. YMMV. It's light and that makes it more maneuverable than my gasoline mower. I can't start my gasoline mower because I don't have the wind, but this just starts with a button and a bar,. I can do that. I don't care how it looks. I didn't buy it because it's electric. I bought it because gas mowers are too difficult for me to start. ... show more

    • It works great
Size: 21" Self-Propelled
It worked out great! I used it today. I had to get used to it and how it operated, but it turned out fine. I love it! It was easy to assemble. It took me 15 mins including opening the box. Size is good. Start time is awesome. It starts up right away. Maneuvers great. Thickness is ok. Good value for the money. Very Highly recommend! It cuts pretty good. But you need to go over the edges and corners with a weed eater. And if you want to cut it down some more you can use a weed eater over it. You need to watch the wet grass. It’s better if you cut in the afternoon, when the lawn dries a bit. That can give you a better cut too. ... show more

    • Surprised Me With How Well It Works
Size: 21" Self-Propelled
Just bought a new house with a smaller yard, so I needed something more practical than my old riding mower. I honestly didn’t expect much from a cordless push mower, but this one performed way better than I thought it would. The 80V brushless motor has plenty of power, even when the grass was a bit longer in spots, and it handled everything smoothly without stalling. Charge holds up really well—I didn’t feel rushed or have to stop mid-job—and the self-propelled feature makes it easy to get up inclines without much effort. The build quality feels solid too, and it’s heavier than a lightweight push mower, which actually makes it feel more durable. My only minor nitpicks: the foam handle seems like it could wear over time, and the safety “double-on” system takes a second to get used to, but neither is a dealbreaker. Overall, a solid mower that makes a smaller yard feel like a breeze. Would definitely recommend for anyone downsizing from a riding mower. ... show more
