        Q:Does this mower do well with hills? I have a moderately steep hill in my yard, though it is not long, and I need self propelled and would like electric.
        by|Jun 25, 2023
        2 Answers
        Answer This Question

        A:  One thing to note about these electric mowers is that they don't have a big engine, gas, or oil - so they are way lighter than gas mowers. They are much easier to maneuver up and down hills.

          A:  Hello, Alice - Thank you for your question. As long as the hill is not greater than 15 degrees then you will have no issues. I hope this helps!

            powerful, easy, reliable!
            [This review was collected as part of a promotion.] I’ve been using my Ryobi for 4 years, and it is a dream!!! Starts so easily, runs quiet but so powerful at cutting our grass, even when it gets high. Easy to use with the self-propel - just love it!!! Good run-time on one charge as well.

                I've used the mower only twice now, and already the rear deflector has come off and I can't figure out how to put it back on.

                    Electrical burnout
                    I bought the older model in May 2019. This summer it started cutting out then quit. Upon inspection the connector burnt out. The only repair Center is two hours away. How can this happen to a machine that is supposed to have so many safety features. Yes it’s 5 years old but only used in the summer on a small yard. Very disappointed is an understatement. Why should I purchase a Ryobi products. This machine should last for many many years. If it didn’t quit my review would be a 5

                      Very solid value
                      [This review was collected as part of a promotion.] Used this for the first time today and am definitely satisfied! Setup was a little confusing but once you understand how it works its very simple. Endurance was basically as advertised, maybe even a bit longer! I had let my lawn get pretty bad so this had its work cutout for it.

                        Love the lawnmower, but the service is even better
                        [This review was collected as part of a promotion.] Got the ONE+ 18v Lawnmower in Oct 22 and really enjoyed the quiet performance. Yard looks great after mowing. I had an issue with it and the great support team (actually Katherine!) went out of their way to help me through it.

                          Great lawn mower for small yards
                          [This review was collected as part of a promotion.] Thisisa great lawn mower. It is light weight making it easy to push. I have a small yard so I only used about 1/2 the battery capacity to mow the entire lawn. The only thing I see as a problem is the rear of the grass catcher bag is not supported so when I back up the mower the bag tends to curl under. I am going to add some velcro ties to the back of the bag so I can fasten it to the metal frame bar.
