Greenworks 80V 21in 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.

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.

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.

Light weight, quiet , easy to assemble, and effective at mowing, this 80 volt mower, self propelled, cuts my city sized lot using about half of full charge. Well designed and engineered with operator in mind, its use is a pleasure to use.

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!

I preface this review by stating I own 3 other tools from Greenworks: 1) blower, 2) line trimmer, and 3) edger. The difference between my existing tools and this mower are my existing tools are all 60v. I think these other tools are easy to use and dependable. For the review on the mower, this is the 80v Greenworks 21" brushless self-propelled lawn mower. It has the LED headlight. I ordered it on 8/31/2024 right after my gas power Toro died. The shipping took a while, but I received it on 9/9/2024. I didn't get to open the package until later that evening. Since I knew the battery would need to be charged, I only got out the battery and charger. This is when the issue arose. I plugged in the charger and inserted the battery into the charger. With the newer chargers, a fan has been added, which I assume is to help keep the battery and charger cool while charging. My old 60v chargers do not have the fan. The fan ran for a few seconds and the green light start flashing indicating it was charging. So far, so good. After about 5 seconds the fan stopped on the charger and the green blinking light stopped. I waited another 5 seconds and the dreaded red flashing light came on. I knew from other Greenworks batteries and chargers this is not good. On my 60v chargers, the red light means the battery cannot be charged because of some issue. This is normally that the battery is too hot. Waiting 30 minutes with the battery out of the charger usually does the trick. After that, I can resume charging the battery. Since the 80v was brand new, I immediately became concerned. I tried removing the battery, waiting, and trying again. No luck. I tried using different outlets in my house. No luck. I even waited over night and tried everything all over again. No luck. I assumed the battery or charger were DOA. FYI the 80v batteries do not fit in the 60v chargers. Therefore, there was no way to check if it was the charger. I called Amazon who said I could send the entire package back or contact the manufacturer directly. I really wanted this to work so I opted to call Greenworks. The agent Tyler did what I expected and asked me to try everything all over again. I patiently went through all his steps which produced the same results. He then had me try the battery in the mower. As I stated above, I had not even un-packaged the mower yet because I was first trying to get the battery charged (It did have 1 bar out of 4). I asked him to hold while I un-packaged everything. Eventually, after about 5 minutes of wrestling with packaging material, I got the battery into the mower and started it. It worked fine. At this point, he asks me for the serial and model numbers for the battery, charger, and mower. I gave all those to him and he asked me to wait. After a few minutes he comes back on says since I only have 1 battery, we don't know if it is the battery or charger. Therefore, they will start by sending me a new charger. I agree but am not liking this solution because they could just as easily send me a new charger and battery and make this right. However, Greenworks apparently doesn't value their customers this way. Since I don't really have another choice except sending back the mower. I agree with his proposal. At this point, I am thinking they can overnight this to me and still make me happy. Tyler then explains to me he will get the request processed today and I should receive the replacement charger in 10 - 13 days! I asked him to repeat the number of days. He repeated the 10 - 13 days but added "it would probably be less." I reminded him that I have already been waiting for this to arrive and now I will potentially be delayed another 13 days. He was not moved at all. I asked him if he could expedite the shipping since this is brand new product and clearly a manufacturer issue. He said he would check. I waited. He comes back and seemed to have forgot my request for expediting the shipment. He restates it will be the original 10 - 13 days. I ask kindly if he can possibly find a way to expedite the shipping since this is brand new and has at least one or more faulty parts. He starts checking something again and says he will check on it and see if there is a way to expedite the shipping. Of course, he follows that up with saying he wasn't guaranteeing anything and said he would do that later sometime after we hang up. I then asked what if the charger doesn't fix the issue? He says that I then need to call back. They would then ship me out a new battery. I said that sounded bad since I would then be waiting another 10 - 13 days. He again said he would try to expedite the charger. However, it felt like he was just saying that to get me to hang up. He also added again there were no guarantees on the expedited shipping. I thanked Tyler for his help and hung up. Now, I am waiting for who knows how long to receive a charger that might not fix my issue. There is a 50/50 chance it is the battery. If so, then I will be waiting about an entire month just to get this mower working. For now, I am not happy at spending over $400 on something that cannot be used. I will have to get a friend's lawn service to mow our yard since I can't wait another 10 days so there's another $50. I rate this product at 1 star due to their customer service not wanting to help me get the issue fixed sooner rather than 2 - 3 weeks. I am thinking if it is the battery, I will just return the entire mower. They will then have to pay even more for shipping.

As advertised. I have trouble manually pushing a lawn mower so having the “self propel” feature was a must. It has several height options that are easy to adjust. Easy to use. VERY fast on the fastest setting so start on the slowest setting. Powerful and does exactly what I needed it to do, takes half the time to mow the lawn now. Would highly recommend, especially for those who have issues manually pushing a lawn mower. :)

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

The issue where you cannot immediately pull it backwards after stopping forward movement is 100% an engineering screwup. You have to give it a little shove forward by yourself after it comes to a stop to move it forward a couple inches, in order to unlock the drive wheels. Or release the drive trigger and allow the mower to roll forward quite a ways.......Stupid design ... My 91 year old Mom will have a very hard time adjusting to this, she probably may never quite get there....and that's who I bought it for. Apart from that its OK and the height adjustment is very easy to operate which was great.
