          Easy to use, no gas, oil, and save time!!!
          I bought it and used mine today and it was amazing. I read lots of reviews before I decided to buy it. But it worth the money and save me time. I am happy with it. No gas, oil, maintenance, and can cut all my patio in one charge. The second battery I didn't have to use it. Recommend for everyone...

              Five start lawn mower
              I wanted to upgrade from the corded electrical black and decker, which was still running. After researching, I bout the 21 RYOBI with two batteries. We have other RYOBI tools but this one is a 40v battery while the other tools are 18v. The machine runs amazingly smooth, it’s not noisy (although I still protect my hearing) and I love the self propelled function. I’ve been using it to mulch leaves rather than bagging and it’s been doing an amazing job. use battery and a half and no issues so far.

                Blade cut into deck of mower
                I used it for the 1st time today and it was good. Great power and only use 1 of the 2 6Ah batteries that came with it mowing my yard. My yard is average size. Charging the batteries were in a timely manner. My only complaint is that when the mower went from cutting a flat surface to an incline or decline the blade would cut into the deck of the mower. The incline or decline was not steep. My guess is the weight of the mower is heavy to the rear causing the deck to flex enough when going over incline or decline that the blade cuts into it. Kind of disappointed since paying almost $700 for it

                  Ready to use out of the power,quiet ,powerful !
                  [This review was collected as part of a promotion.] Tired of my 5th gas mower breaking down and was in market for new mower. A friend of mine purchased a Ryobi rider and i was impressed but that was too much machine for my needs. Ironic, my neighbor was using the model, figured I'd get his on hands opinion and he said without hesitation "Get it, I love it"... so went with this model and wow I'm nothing but impressed! Had 4 months now and its been great! Super quiet, I can mow at 9pm and not disturb the neighbors. Battery charges in an hour or less. Powerful, cuts with ease, honestly has reduced my mow time! Came right out of the box ready to use, which was awesome, was expecting to do some assembly. I am so pleased with this machine I'm going strictly all RYOBI for my electric tools! Next is the weed eater. I highly recommend!

                    Rust
                    I have had this product now a little over a year now and just the other day I started to see rust color coming from under the mower into the bag. I love thios product until now. I have tried to get in touch with Ryobi but they never reached out. I paid almost $600 for this amnd now I am very disappointed

                      Wow! So amazing!! The Best Mower I've Ever Had!!
                      [This review was collected as part of a promotion.] I had a gas mower (different brand) that kept giving me problems with starting and staying running, I then had an electric one (different brand) that worked great but after a summer of dragging the extension cords around and getting tangled I had had enough! I already had a large Ryobi tool collection so I immediately started looking at Ryobi mowers. At first I looked at 18v because I had several batteries already obviously but due to the size of my property I talked myself into the 40v series which I didn't have any 40v yet. I watched for sales and just missed the free trimmer deal by a week. Went to my nearest home depot which was 2 hours away (I live in a small town in Nova Scotia Canada). The sales guy actually honored the deal and also signed me up for the credit card so I got a discount too! I was very happy driving away obviously. Got home, plugged the batteries in to charge and the next day I was mowing with ease!! The cruise control slider helps as you speed up the drive going up hill and slow down going down. It's a no brainer and very quiet and obviously no fumes like my old mower! The 2x 40v 6a batteries mow my entire property on a single charge so that blows my preconceived ideas for it not lasting long enough. I wish it had a dual battery charger but that is something I will deal with. I am now confirming my choice to go for 40v was the best outcome for sure. Love all of my ryobi collection and now chores and hobbies are not only easy but fun... yes I said FUN!!!

                          Poor Bag Attachment Engineering
                          Mower is great. However, the bag attachment is a complete fail. The hard plastic bottom of the bag has curled up to the point it interferes with the ejection of clippings.
