Q:Is it okay to pull the mower backwards when necessary without harming the mower?

Q:I read pages 8 & 9 for installation; the process to install bag, adjust height, direct grass discharge requires removing key and battery every time! Is this too complicated for a woman? Why is the bag not factory ready to insert in mower? Sounds tedious!

Answer This Question

A:  Hello, Dmcm - The start key and battery should be removed after each use to prevent accidental starting. The grass catcher bag only needs to be installed if you plan on bagging the clippings. The bag only needs to be put on the included frame and then hooked to the mower. If you need any assistance with your mower, please reach out to us at 1.800.525.2579, Monday - Friday from 9 am to 5 pm (EST), or through email when you visit us at https://www.ryobitools.com/support/contact. We hope this helps!

      Q:Is it easy for a 60 something woman to use, how hard is the pushing and pulling?

      Answer This Question

      A:  Very lightweight compared to my old gas mower. Rolls nicely and the height is easy to adjust. It almost feels like pushing a toy at first but it is quite nice to use. For a little more money though, the self propelled version would make it even easier

      by|Apr 11, 2024

        A:  If you have hills or areas that require tight maneuvering, you may want to get a self propelled model or maybe the 18v model that is less wide. I use this for trimming small tight hilled areas and I wish I bought the smaller 18v model.

        by|Apr 11, 2024

          A:  Hello, Sarah - This lawnmower weighs 43 pounds with a battery attached and should be easy enough to push when you are mowing. If you would prefer a self-propelled version, we recommend checking out model RY401180 at this link: https://www.homedepot.com/p/RYOBI-40V-HP-Brushless-20-in-Cordless-Electric-Battery-Walk-Behind-Self-Propelled-Mower-with-6-0-Ah-Battery-and-Charger-RY401180/317061072.

            Side Discharge Chute doesn’t fit
            The Side discharge chute that came with the mower is too big. It doesn’t fit.

              Run time
              This product claims in the description, “up to 48 minute runtime”. “Up to” is a key phrase I guess. On a full charge, day 2 of owning this mower, I timed it at 18 minutes, for the run time. Only 30 minutes short of the claim on the description. Piece of garbage, I do not recommend purchasing this product.

              Hello, Tmal - We're sorry to hear that the run time isn't what you were hoping for! Many factors impact the run time, such as the tool being used, the amp-hour of the battery, and/or work conditions. And we would like to connect so we can learn more about your experience and provide you with support! If you would, will you please be looking for an email from us at Reviews@RYOBItools.com?

                I have about 15 of the various Ryobi One+ 18-volt tools, including a 16"-cut push mower, and have been very pleased with those. I use the 16" mower at my 2nd home that has a very small (.15 acre) lot. I bought the 20"-cut 40-volt mower for my primary home which has a much larger lot and much thicker grass, which I am pretty sure the smaller mower won't handle. I've been impressed at how well the 40-volt mower does on the larger (.70 acre) lot. Only drawback is not being able to share batteries between the two systems. I suggest buying 2 of the 40-volt batteries, as one won't cut my entire yard. The mower does have a handy on-board storage area for a 2nd battery.

                First mower....wow!
                I just got the mower, leaf blower and weed Wacker today. I easily set up, charged batts and ran the items. Love the quick height adjust lever, and the units auto sensing of thick grass...it actually speeds up and cuts harder, automatically! My grass was up to 4" in spots and I hit them one notch down to start. After doing my 70x140' L shaped yard with height 3/4 way down, using all 3 tools on the same 6ah battery, I had 3/4 bars left! WHAT?! I can get 2-3 full cuts out of one battery. I'm loving this!

                  Great battery life
                  With my previous electric mower, I wasn’t able to go the entire backyard and front yard at it’s thickest without having to break it up into at least two sessions. I was able to complete me front and back yards on a single charge without depleting the battery. I like how there is storage for an additional battery. Highly recommended !

                    defective out of the box
                    Second time I made an attempt to buy Ryobi 40V tools again absolute poor quality, and the worst assembly manual I’ve ever seen in any product. Exchanged at the store the weed trimmer tool, brought it home and the shield on the new trimmer one is broken.

                      Pretty good Gas replacement power head
                      Black fiday deal!! But the 40V power head is Great!! I was able to weedwack 1/4 acre lot with chainlink fence, givien it's not growing season I was able weedwack both sides, edging and driveway then used blower (turbo is great!) and the battery still had 2/4 led. The trimmer head works but kicks up a lot of rocks and sand. I put my old trimmer head and it works great! I used the it on low speed most of the time, the trigger on 40V head allows for much more control that my old 25cc craftman

                        I don’t have a large property however, my backyard gets overgrown quick (turns into a jungle). Especially because i work an average of 130 hours a week I don’t get to mow as often. It’s not just grass and weeds, it’s also small seedlings from surrounding trees and this mower plows over them with no problem!!! 10/10 would recommend!!!

                          Stopped starting after 3 months
                          Stopped starting after 3 months of average use. Not sure what’s wrong with it. I liked it while it was working, I had the older model for years and no issues but this one quit after one season. Very disappointed and would rather just buy a gas mower than deal with the hassle of trying to mail this back to Ryobi
