Greenworks 80V 21" Self-Propelled Cordless Lawn Mower – Brushless Motor, LED Lights, 4.0Ah Battery & Rapid Charger (75+ Compatible Tools)

I am surprised and delighted by the power, efficiency, and ease of use. I purchased the Greenworks 80V 21” Self-Propelled Cordless Lawn Mower when my old gas powered mower recently seized up and stopped working. I’ve always been very skeptical about electric mowers having comparable power and ability to cut through thick Saint Augustine grass. To my surprise and after about 8-10 lawn cuts, I’ve been totally convinced and happy with this mower. I have about 1/4 acres of Saint Augustine grass - and the battery lasts for at least 3 mowings and cuts through thick wet grass like butter. Because it’s an electric mower, it’s extremely quiet and very lightweight. The mower is self-propelled, however, it’s so light, that I find myself pushing it with ease around islands and tighter spaces. It’s also super easy to start… no more throwing your shoulder out by pulling string-cords or running out of gas. Overall, I can’t recommend this enough for the power, cutting-ability, agility, and battery life.

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.

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.

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.

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.

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!

So, I've got a 10+ year old Honda/Briggs and Stratton push mower that I change oil, spark plugs, filter and blade on every year or two. Engine is going strong but the deck is rotting out underneath it and I've rebuilt the front wheel supports 3 times. After numerous repairs to Frankenmower, I decided to get something new and I was enthusiastic about trying an electric mower. I bought this one (and the extended warrantly because I hoped it would be something I could keep for years), assembled it, fully charged the battery, read the manual etc. Assembly was fine, with the exception of a poorly placed pre-drilled hole. I was overall impressed with the sturdy feeling, moderate weight, and I really liked the option for vertical storage. Started easily, and the noise and vibration is marginally but noticeably lower than a gas mower. But when I tried to actually mow with it? Unbelievably disappointing. I had it set at the second highest detent, for grass that was not particularly high (Illinois, September, standard suburban lawn). It made about 3 passes before it started to struggle, then repeatedly gave up. Restarting it repeatedly resulted in the same thing each time. It simply lacked the power to deal with standard lawn. Battery still read full... I pulled out Ye Olde Ancient Frankenmower, aligned the wheels more or less, added some unleaded, and finished the lawn without a problem. I'm a fan of innovation and I'm ready to move to the improved version of mowing - this is NOT it. This machine is not up to the task it was designed for. Hugely disappointed. If you are mowing SMALL amounts of LOW, DRY grass, this might do the job. Anything more, I do not recommend. Kudos to Amazon for their return policies - The customer serviice is the primary reason I keep shopping with them. This unfortunate experiment is going back.

The quality is quite good. Assembly was very easy. I mowed the lawn for the first time today, and my impressions are very positive. I mowed at high speed. Considering the grass was very tall, the mower handled the challenge admirably. It offers good maneuverability; in some spots (such as fence corners), I had to push it back and forth, and it moved with ease. The battery didn't last quite long enough to cover one acre, so I had to order a second one. However, the manufacturer guarantees coverage of *up to* one acre, so everything is as expected. As for charging: a full battery charge took just 35 minutes—SUPER! I am very pleased with this mower. I highly recommend it.
