          Excellent Mower, but with severe Engineering flaw
          Every 40v Ryobi lawnmower suffers from the same basic engineering design flaw, but fortunately is easy to fix. The issue is lack of heat dissipation & the fact the encasement traps heat. This leads to batteries overheating far more frequently & reducing the lifespan of batteries. To fix this design flaw, remove the top of battery encasement. [See pic] You’ll extend the life of your mower & batteries, plus it’ll seem more powerful unit as it’ll be more efficient operating in a cooler environment.

            So far it’s good
            We only bought this mower a couple of weeks ago. We’ve always used ryobi products, so we were excited to get our first battery operated mower. We have used it twice and it does a great job. So much easier to use than our gas mower. And so much quieter! However, after we have noticed the handle separating at the seam ehich exposes the cords and wiring. Our complaint begins here. We have tried reaching out to ryobi and can’t get through to a real person to explain the issue. The live chat gives us information that doesn’t pertain to our issue ie: have you tried troubleshooting the problem?! I’m sorry but that won’t help at all! We finally gave up and tried the extended warranty that we purchased from Home Depot. We couldn’t get through to them either! What ever happened to decent customer service?! We spent 500 dollars on this and would like for it to look new at least for a while. We tried calling Home Depot to talk to them and ended up on hold forever! Maybe we’ll just carry it into the store and return it, Eve though we no longer have the box! We really just want the handle fixed. Yes, we would recommend this mower, but , if anything is broken or you have any other reason to get help with it, be prepared to not get any help.

              Pickup was great Home Depot associate help me load it in my Jeep! Was nice enough to make make sure flat cart was dry before putting box on it. I love my electric mower, only uses 1 battery for my lawn.

              I’ll never go back to gas!
              [This review was collected as part of a promotion.] Had the mower for a little over a month. It’s everything I wanted and more. I never realized how much my gas mower made me smell like gas. The self propelled is fairly quick and easy to speed up or down. I cut grass that was about 4”-5” tall and cut down to about 2” with no problem.

                Works well
                [This review was collected as part of a promotion.] I just purchased this mower and have only used it once. So far, so good. I got my entire back mowed and only used 1/2 of the battery while using the self-propel feature most of the time. My gas mower still works but it was not self-propelled and at my age (72) it was getting harder to mow my 1/5 acre lot. It came fully assembled, just flip up the handle and you are pretty much good to go. I don't bag my clippings so I do use the mulching plug and that was easy to install and appears to work very nice. My lawn is very un-even and it appears that the mower pretty much takes that in stride. I do mow high usually, and my old mower didn't mow high enough but this mower has plenty of adaptability when it comes to height adjustment. Time will tell how well the mower holds up and it did take a little time to get used to.

                  Impressive Mower
                  I was a bit skeptical about buying a battery operated mower but so glad I did. I have a lot of ryobi tools so this is just one more ryobi tool in my arsenal. It is quite, starts so easy and mows just as good as my old gas push mower. I have a small area to mow so I decided to buy a push mower. So glad I went with ryobi. They make great hand tools and now push mowers. No more having to stop to run and get gas. I just make sure the two monster batteries are charged and off i go.

                    Buyer Beware! No Reply from Warranty!
                    Shortly after getting it, a bolt near the blade went missing. I contacted Ryobi on 8/9/22, about the warranty asking to ship me a new bolt. I worked with Brandon. On 8/25/22 he ordered what he thought was the right bolt. I contacted him again on 9/1/22 and 10/17/22 to let him know that this was the wrong bolt. He responded on 10/17/22 saying he has forwarded my issue to tech and promised to get back to me. I never heard back. I wrote to him again on 4/16/23, 5/3/23, and 6/6/23. Nothing back. Sad

                      Good mower if the wheels stay on
                      Writing this review after my first use — Pros: Pre-assembled, great battery life, very user friendly Con: One of the rear tires fell off during the first use and was difficult to get lined up and reattached. Fingers crossed that it’s good to go now, but annoyed by the inconvenience at this price point.

                        My Toro 163cc 21”gas powered mower finally died after 8 years on Easter. Since I’m already heavily invested into Ryobi Tools, I decided to buy one of their battery powered mowers. It superseded my expectations! It was more powerful than my gas mower and didn’t bog down while scalping and bagging dormant Bermuda grass. I was able to cut my 8,000 sqft lawn a lot faster, and I only used one of the two 6ah batteries!

                        I used this once and the plastic flap on the back broke- I’m pretty annoyed. Everything on Reddit says it’s not necessary but for $500+ you’d think it wouldn’t break on day one.
