Quick review. Arrived in mftr's box ONLY. Shame on Amazon. But luckily, nothing was damaged. I opened the box, assembled it w/o too much effort (all but one thing was just common sense). It looks great, is fairly light weight and pushing it w/o self-propulsion is easy thanks to said light weight AND large wheels. It works great. Battery actually lasted long enough to cut a large backyard with some to spare. Didn't have to charge it but I pushed most of it instead of self-propelled mode. It cuts fine. auto adjusts when the grass gets thicker and you can adj the speed of pulling and there's a turbo button as well. I set it to med speed and pushed it. The only gripe I have is the height setting doesn't go high enough. But other than that, so far so good. Very well made, imo. LOUDNESS: since the company refuses to publish the actual SPL of the thing, I took the liberty to measure it with my dB meter. Loudness measured from handle to motor in stationary mode is A-weighted: 79.0 dB and C-weighted: 85.4 dB (give or take a few decimals). SEE PICS FOR PROOF and wear hearing protection while using this! That's all, folks!

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.

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.

There's a bit of a learning curve, lol. Don't wait til you have to turn to practice that. To back up, you have to release self-propel levers, give a slight push forward, then go backward. I don't like that. Battery didn't last as long as advertised, but maybe that's my grass. Battery charges FAST, which is great. Self-propel feature works great, and is adjustable. It's not fast or slow, that's nice. It seems to have some power. I have a 0.66 acre double lot on a corner, so big yard. This is easier on me than the 60V push mower, but my shoulders and biceps are pretty sore after cutting about a third of yard. Not as quiet as my other one, but still far better than gas. It was super easy to put together. I'm a 58 year old female, average physical shape.

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.

Works great! I ordered this because I was sick of my husband having to mess around with gas, carburetors, pull starts, the smell, noise, etc. Not to mention when he finally got around to mowing the grass was like a wilderness. I purchased this mower for myself so I can do it whenever I want and not have to screw around with the above mentioned. I have a 1/2 acre that is very rough due to my chickens constantly picking & digging, so it's not a smooth ride by any means. However I'm able to use it with ease even without the self propel. The battery lasts the entirety of the 1/2 acre and still has juice left when I'm done. I love that it folds right up for easy storage. It's a bit heavy to lift up and move around when folded but it can be awkwardly wheeled around too. Not a deal breaker by any means. Still 100x better than a gas mower. Important to note- to start the mower you must hit the power button and the 'gas' levers simultaneously. The manual isn't super clear on that. I thought I had a dud until I looked up a YouTube video. Because this works so great I've ordered the Greenworks leaf blower and weed whacker too. Can't wait to try them out.

My latest "yard guy" quit on me, so I decided it was time to take matters into my own hands! I just received my Greenworks mower a couple of days ago, and I've already been putting her through her paces. I absolutely love her and even gave her a name: Bunny! 😊 I have a large yard, so this mower is definitely getting a real workout. I'm still waiting for my second battery to arrive, but honestly, I haven't minded the downtime between charges. I have mid-foot arthritis in both of my feet, so the charging breaks have actually encouraged me to rest instead of trying to push through all at once. The self-propelled feature has been an absolute game changer. It has made mowing so much easier and far less exhausting. So far, Bunny has been doing an amazing job, and I'm genuinely impressed! I'll continue putting her to the test and will come back later to update my review with my long-term thoughts. Ironically, my former yard guy couldn't seem to keep up with this yard even with a riding mower. Meanwhile, Bunny (my Greenworks mower) and I have been happily knocking it out together. I never expected mowing to become something I actually enjoy! P.S. - 57 year old female here braving the Missouri heat and humidity through all this! Just sayin'! ...Hoping that might encourage others to give this mower a try!

Great mower, but plan on spending hundreds of dollars on batteries, as I need 2-1/2 batteries to mow a little over a quarter acre of yard. I figured it out: the price for my three batteries, I could have purchased 10 years of gas, so if value and not switching out batteries is what you are looking for, this is probably not the mower for you. On the flip side, if you want a quiet mower with a good cut that you don't have to change oil and air filters, this is a great pick.
