      Hello, Kevin - Run time will vary depending on different variables, such as outdoor conditions. However, this mower can provide a run time of up to 50 minutes with the included battery fully charged. And to help get the most run time, we recommend mowing in dry conditions and maintaining a regularly cut lawn. If you need further support, then feel free to ask another question.

          Does this unit really weigh 57 lbs? The other model of 20 inch only weighs 43 lbs and am wondering if the newer ones are that much heavier.

            The reason I asked is this. What did they do to add 14 pounds to this mower. The light weight was what I liked as I have 2 older models. But adding another 14 pounds makes it almost as heavy as a gas mower so you lose that benefit.

                    Easy to Assemble, Easy to Love
                    [This review was collected as part of a promotion.] This Ryobi 40V Brushless 20" mower was extremely easy to setup!!It was two simple bolts for the handle and I was ready to go. It works flawless and the single lever cutting height adjustment makes changing the levels quick and effortless. It's noticeably more quiet than a gas mower, which is a huge plus since I can now comfortably listen to my music or the news while mowing. Overall, this mower has been a smooth, hassle-free experience. Also I must state, I received this product as part of a family and friends campaign! Efficient, easy, and simple to setup.

                      Thoughtful design
                      [This review was collected as part of a promotion.] What a cool product! First, the mower arrived with solid packaging that was well constructed but made it easy to unbox. Assembly was fast, easy and pretty intuitive. Unit came with one battery. Out of the box, it required a full charge, but the charging was pretty fast. Once assembled, I thought the mower design was pretty cool and very functional. The battery compartment opens and has a place not just for the battery powering the mower, but it also has a slot for a back up unit. I also appreciated the bag design; it attaches easily and has a wide mouth that makes dumping the contents pretty easy. I mowed my yard, which due to some seeding, had not been mowed for two months, and was very thick. The mower handled the thick grass pretty easily. It revs the motor to a higher speed when it needs some extra power and then slows back to a regular power level once in areas that do not need the extra power. From assembly to usage, the mower was thoughtfully constructed. It seems sturdy, was easy to adjust, and simple to use.

                        Awesome mower!!
                        [This review was collected as part of a promotion.] The Ryobi 40V Brushless Push Mower Kit is a fantastic upgrade from gas mowers. It’s powerful, quiet, and easily handles thick grass. The battery lasts long enough to finish my yard on one charge, and the push-button start makes it incredibly convenient. It’s lightweight, easy to maneuver, and delivers a clean, even cut. No gas, no oil, and easy storage make this mower a great choice. Highly recommend!

                          Perfect Mower!
                          [This review was collected as part of a promotion.] This mower will be PERFECT for my situation. I needed a mower at my office and was tired of hauling mine from home. With 50 min of runtime, this will give me all the runtime I need to get the job done. It also opens the door for me to get more 40V products and add to the collection. It will also be super easy to store with how it folds up when I’m done. This review was collected as part of a friends and family campaign.

                            I really like this mower. If you only have a small area, you don't need self propelled. This maneuvers easy, turns easy, starts easy. Other reviewers said the mulch cover is difficult to put in place. If you put the mower vertical, you can see the slots to snap it in place. I like that it stands vertical for storage and you can move it like a suitcase. The most difficult thing? Putting in Ryobi extended warranty info. I've used the mower in 10 minute intervals, cutting weedy or high areas. I have a rider for the entire yard, but for a small section, the Ryobi is ideal and time saver. Put the battery in and go.
