80V 21 in Self-Propelled Lawn Mower, 4.0 Ah Battery and Charger

I never expected to write a 5 star review for this mower, but alas here it is! My old Toro gas mower died 2 weeks ago and I ordered this 80v Greenworks model because it appeared to have more power than the (2) 40v. to go up hills, and yes indeed it does! It came overnight, so I was able to finish the mowing from the day before. Setup was a breeze with only a few parts to assemble, it was ready to go in about 20 minutes. The self propel on full power (yes, it's adjustable if you want to go slower or on flat land) worked just as good as my old Toro, you can see the steep backyard in the photo. I am also very pleased with the battery time. For my yard, it takes about 20 minutes to do and it used just 1/4 of the battery. So I used it a second time without charging it and it used another 1/4 battery. For those who mentioned that you have to pause if you want to walk backward with it, you're correct but I think I've figured out that if you simply lift the back wheels a tiny bit, it disengages the self-propel more immediately to go back without any tension. I like that the unit is a pretty heavy steel, I was afraid it would be more flimsy but it's very sturdy. The blade cut perfectly too, a nice even cut after a simple adjustment that raises or lowers all the wheels easily. This is a perfect fit for me, I can only hope it lasts 15 years like my old Toro.

Great mower,like slow speed. I do not have to chase this mower, at 79, it moves slow enough for my bad legs to keep up with. Light weight and easy to push or pull if have to. My gas mower is twice as heavy, this is well built and cuts good, like not having gas and to buy oil for a mower. Handle folds over easy and can store on rear wheels not worry oil getting into piston cylinder and clog up starting engine. Charges fast. Easy to clean and store.

Easy to use and gets the job done on my slightly larger than average neighborhood lot (St. Augustine grass). Turbo kicks in whenever needed for thicker grass. Easy to adjust height, in fact very easy. Not too heavy so I do not have to use the self propelled functionality, it just makes it easier after turns near the fence to let the machine do the work for the first few steps. Good price compared to competitors. The only complaints and why this gets four rather than five stars is you need to make sure to quick the self propelled function a step or two before the end of a run as otherwise the back wheels lock when you try to turn. You get used to it, and it isn't a big deal if you forget, but it is a little wonky. More of an issue is the mulch quality which is only adequate. The mulch could and should be improved a little and it would be better. It is adequate at mulching, but nothing more. That said, I am happy with the purchase and would not feel bad recommending this as it is overall a good machine at a very competitive price. Secondary market batteries are available at a much better price than OEM, and the one I purchased works like a charm.

This is a great mower for me. I am a 70 yr old woman and I can easily mow my yard with this self propelled mower. So easy to operate and the battery stays charged for about an hour.

I am a FTHB and moved into my new house in June 2025. When I was growing up I have vivid memories of my dad and I fighting out gas lawn mower. "Did we prime it" "Is the starter out" etc. This electric green works is absolutely amazing plus its at a good price point. I love that you can either side discharge bag or mulch your clipings. I also like the height. I have a St. Augustine lawn and love mowing it tall to show of those fat juicy blades! I also like when adjusting the height there's just 1 hamdle that controls all 4 wheel heights. The mower can go super fast practically a run but I typically run it at its slowest setting. The battery charges pretty quickly and last for both front and backyard mods. Would recommend to anyone in the market. I truly think this mower beats out the bigger more well established companies!

My second Greenworks mower. Very pleased with it. Batteries from the old one work in this one just fine. Comes with a small battery. Otherwise it’s just great. This new one is more powerful but operates just the same. Easy to use and reliable. Nice size for typical suburban yard. Not sure why it has lights. I have yet to mow in the dark and I’ve been mowing almost 70 years.

I've only mowed the lawn 4 times so far with this cool new mower. Okay, I am comparing it to a 20 year old 6.5hp Toro. First off, from a techno geek perspective, it looks cool, and has cool tech like LED lights and fly by wire operations. As far as grass cutting, it has been perfect. I'm still experimenting with ride height, but I do believe my old Toro "vacuumed" up leaves better, but again, it's still under observation. Not having to pull start is priceless. All and all, I would definitely buy it again.

This is my third Greenworks lawnmower, and they just keep getting better. I should probably mention that I replaced the first two for technological improvements, and not because they failed to work. This mower has a self-propel feature that is much more attractive to me now that I am older, but it has the same intuitive operation as my previous mowers. It is simple to understand, simple to operate, and a lot quieter than a gas mower. That means I can use this mower early in the morning or later in the evening without having to worry about complaints from the neighbors. In fact, my neighbors tell me they can't hear the mower at all, even when I am using it just a few feet from their windows. That's a huge plus when your neighbors' houses are very close to your property line. And not having to deal with gas cans and motor oil is a big plus, too. I mentioned the self-propel feature - I disengage that when I am approaching a flower bed or fencing, just to make sure the mower doesn't get away from me. I'm not really sure that's necessary, but it does give me a little peace of mind, and the ability to switch back and forth between self-propel and manual in an instant is another really nice feature. Because this is an electric mower, it's not only quiet, but it starts instantly, too. No more pulling cords and hoping the engine will catch. The batteries recharge quickly, and they hold a charge well - I charged my batteries at the end of last summer, stored them in an unheated outdoor cabinet all winter, and 6 months later they were all still fully charged and ready to go. I have a large yard, so I keep at least 3 batteries - I use one, put it on the charger, use a second, and by the time that one needs to be replaced, the first one is fully charged. It's not necessary to keep multiple batteries, but it saves me enough time to make it worth the investment. As for the value, this mower costs about twice as much as an entry-level gas mower, but it is well worth the price. It's more reliable, more environmentally friendly, easier to use and it never runs out of gas. I am Team Greenworks for live.

Very pleased with the way that it evenly cuts. More impressed with the speed contols on the self propelled. Light and easy to control

I paid for the mower to be assembled professionally but I got it assembled
