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.

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.

Moving to texas, it's hot as 'heck' here in the summer. I paid others to mow my lawn because I'm fat and lazy, plus I seem to have problems with my gas lawnmower. 45.00 per week and dead spots in my lawn that I swear are being caused by oil, gas or both leaking off these mowers. I did my research and found these and Ego mowers have a lot of power these days, no oil and gas, self-driving and very light. I am only sorry it took so long for me to find this. I'm on half an acre and a single charge works for me. Battery charges within 30 minutes and i've had no issues with its use, my grass is coming back and while I'm still lazy, I'm not as fat. Recommend a second battery just in case and if you find this someplace like CostCo, pay attention to the battery life 4.0Ah should be minimum spec. You can find other batteries compatible with this mower that are even higher Ah values. Higher the Ah, longer the mower will run on that cell.

The mower works great except.... buy a second battery. I have a corner lot the original battery runs out after front and side strip. The second battery( bought a cheap battery works good enough for $79) covers the backyard. No matter how I ran it the original battery cannot do the whole lot. Good news the batteries charge extremely fast. Oh don't count on the light gauge to notify you, it just stops. But as a mower it mulches very well, also the bag picks up almost everything and the height is easy to adjust with one lever.

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.
