                  Great self propelled lawn mower
                  About 3 500 square feet with a few trees and still 2/3rd of the battery remaining. I used to use the wired 11A 13inch and I am happy I replaced it with this one. It’s heavier but you don’t really feel it most of the time due to the self propel and the handle is more comfortable too. As for the power when the wired one use to slow down due to thick grass, this one you hear it increasing the speed and it go through easier!

                    Ryobi is not Quality
                    [This review was collected as part of a promotion.] The structure of the mower is flawed, with metal screws going into plastic that wears out within a year. By year two, the mower is all-but-completely unusable. The batteries won't last either, without needing to be "reset" and you won't get the help you need without paying a pro as much as you'd pay for a new mower! I was leary of Ryo I, but bought a house's worth of tools. I should've followed my gut.

                    Hello, Lv10 - We're disappointed to read about the trouble you're having with your mower and batteries. If you would, please reach out to us via our Contact Us page at https://www.ryobitools.com/support/contact.
                      I have always been a Honda guy but wanted to get away from a gas powered lawn mower so I bought this lawn mower. I love it, it's easy to use and I don't have to fill a gas can to fill the mower so it makes things very easy. I have owned it for 3 months now and I would highly recommend this product.

                        [This review was collected as part of a promotion.] Hi all, Well I went to use my 40 volt self-propelled Ryobi today and nothing would happen. Turns out I took the top cover off After figuring out how to do it and found the very small red wires to the red key to have broken. When I took that cover off I couldn't believe how much debris was in there! Advice to all. Take the cover off once or twice a year and clean all the crap out! The way to get the yellow cover off as you must First Take the Black cover off that is over the wheels. It runs great now. But again, I couldn't believe how much crap got inside that cover. Good luck all

                          How is it that I waited so long to ditch my heavy gas-powered mower? This Ryobi battery-powered mower is so much lighter, quieter, easier to operate, and uses so much less of my energy than that tank of a mower that I had been using! It has plenty of power, includes a grass bag, is self-propelled, folds for easy storage, and is easy to maintain-no oil, no spark plugs, no mess. I'm sold! ?

                          Open box sent as new
                          Home Depot sent me an open-box item while claiming it was new. The package was damaged, the packing inside was messy, and the charger itself had scratches. It’s obvious they’re hoping most customers won’t bother with a return as long as the product works. That’s a shady and dishonest way to do business.

                            Happy after first use
                            I bought this mower to replace a gas model that served me well for many years. It only took about an hour and 10 minutes to fully charge the behemoth battery. Operating the mower and adjusting the right walking speed and blade height is fairly straightforward. My property is a little less than 1/4 acre with 3,400 sq ft of lawn area front and backyards. The mower performed well and blade speed adjusted for some thicker rear yard areas that hadn’t been mowed in a few weeks. I checked remaining battery when finished and lights showed 50% remaining but once I dropped it in the charger only one light was solid and 2nd light flashed so actual remaining battery was between 25 and 50%. I’m happy because that’s more than enough to complete my yard. It isn’t whisper quiet but much quieter than a gas mower for certain. I can mow and listen to music fairly easy. I used the self propelled feature for probably 90% of the time so great that the battery handled it fine. I also like that you can store it vertically once the handle is folded. I hope on the long run this mower holds up well.
