    • 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

    • Great Electric Mower!!
Size: 21" (4.0Ah) Self-Propelled
I feel very good about this purchase. Easy getting it out of the box. Fast setting up. Instructions “pamphlets” needed to be together, and they were too small. Basically they need to explain the setting up process Better. Started right up and it had plenty of power. My yard is somewhat small, The battery usage was exceptional, only one indicator light was used out of 4. The cut was very good. The Self-Propelled was very good especially the controls on the handle. I always thought I was a gasoline man, this Electric mower certainly held up to the gas engines. Mower was very quiet. My biggest Complaint is the way you backup. The first few times the rear wheels would lockup, only for a brief second. So I learned just to briefly pause for a second, then it rolled back effortlessly. My first cut, I chose to use the bagger option. I couldn’t figure out why the bag wasn’t filling. When I finished I removed the bag and found the plastic block for Mulcing was blocking the opening into the bag. Again I blame this on the poor instructions. All in all I REALLY LIKE this mower!! HIGHLY RECOMMEND!! ... show more

    • Awesome mower in every way.
Size: 21" (4.0Ah) Self-Propelled
This mower is fantastic. All my mowers up to this point were gas mowers, which did the trick but high maintenance. I have 1/2 acre of grass. It’s been raining so I haven’t cut it in three weeks it got very tall. This mower cut through it like a boss. It’s light weight and powerful. Two speed self propelled with an off switch if you don’t need it. No gas or air filter or dirty carburetor to mess with. Battery charged up fast and I probably have enough juice left to cut the lawn 2-3 more times before needing to charged it again. ... show more

    • Love this lawn mower!
Size: 21" Mower (4.0Ah)
This lawn mower is easy to use, quiet, and does a nice job! I've never run out of battery power and can cut my whole yard, front and back. It's easy to push. The only thing that is challenging about it is trying to remove the battery from the mower when I'm finished; it's hard for me to hold down the "clip" and pull the battery out at the same time. I don't like that one thing about it, but otherwise I love this mower! ... show more

    • Fantastic mower! No trips to the gas station! Easy mowing! Even old ladies can do it.
Size: 21" (4.0Ah) Self-Propelled
I love this lawn mower. It takes little effort to mow my yard. I just walk behind it and guide it. It does an excellent job. The only thing that would make me happier would be an air conditioner, a water mister, or a fan attached to it. It's too hot here to even walk behind it. I'm an old lady who can't handle the heat. If not for the extreme temperatures, humidity, and constant threats of thunderstorms, this lawnmower would be a great weekly exercise machine. If you live in a better climate, I highly recommend this mower to any senior citizen who has a lawn and needs to exercise. No pushing required. The speed is adjustable; you can take a brisk walk behind it or a casual stroll with it. Forget paying for lawn care and a gym fee. This mower has it all. Except for the air conditioner, fan, or water mister. Hint, hint, Greenworks. The South is full of boomers. Come on. Make us happy. ... show more

    • Operates more effectively than the self-propelled gas mower.
Size: 21" (4.0Ah) Self-Propelled
This is my first battery powered mower! After about 8 weeks of use, I am happy with the purchase. It works well. The 80 V self-propelled mower is quite powerful but admittedly, my lawn is flat. Also, the battery lasts for almost a 1/4 acre but it charges quickly so it is not too much of an inconvenience. On the highest speed setting, the mower almost drags me around the yard. I appreciate not inhaling gasoline fumes in the heat and humidity of summer. The bagger feature works great. The only negatives are that the plastic handle that raises and lowers the mower height is flimsy and breaks easily, so be careful to either tape it before use or make sure that it doesn't rub or scrape anything like the fence. Also, the side discharge guide falls off frequently. Still, this is a great mower. ... show more
