                Summarized by generative AI from text of customer reviews

                Customers say the Ryobi 40V 20-inch self-propelled lawn mower is lightweight, easy to use, and offers a quiet operation compared to gas mowers. Many appreciate the self-propel feature and adjustable speed, which enhances maneuverability, especially on inclines.

                This Ryobi battery mower met my expectations. So quiet and easy to use compared to a gas mower. I would recommend this mower to anyone in the market for a new mower.

                [This review was collected as part of a promotion.] Great choice for medium to small yard. Love the improvements over similar 5 year old model. No longer have to keep rolling forward to disengage gear before pulling the mower back.

                    BATTERY IS USED - PLEASE WATCH OUT
                    ***DO NOT BUY, BATTERY IS USED*** The 8Ah 40V battery that Home Depot sends with this deal is USED, I repeat, **USED**. Please note the battery is FAR more expensive than the tool at 249-299$, that’s how this deal works. PLEASE reconsider your business with Home Depot - or at least check the battery aggressively. My battery has clear use history with the bottom of the battery having the classic 4-line mark indicating it’s been docked to the charger multiple times. It appears to have been in use for months to couple years.

                      Batteries are unpredicitible and will fail or leak.
                      ANY Ryobi mower is just cheap plastic, and the batteries will be nothing but an expensive hastle lasting only as long as the warranty. The fast charger that comes with the mower damaged 2 batteries of mine, one Ryobi refused to replace. The other battery that they did deplaced swelled up, leaked a blue gel and that gel leaked into the fast charger causing it to short out. I would absolutely not purchase one of these mowers.

                        Awesome 40v Self-Propelled Lawnmower
                        [This review was collected as part of a promotion.] I bought this lawnmower 3 weeks ago and have used it 3 times. I absolutely love it. It has a much bigger cutting deck than my previous Ryobi mower (13") and it's self-propelled. You can control the speed and it has a 7 position height adjustment. There's a storage spot for a spare 40v battery for those that have a large property. I do have quite a few 18v Ryobi tools that I use regularly and their great, but the 40v platform has more power. The grass catcher is large capacity, too. The 6aH battery lasts a long time. I can use it to mow my front and back yards, then move it over to my 40v blower and, when I'm done, it still has over 50% battery life left for next weekend. This mower does have a big footprint, but you can quickly fold the handles and stand the mower up vertically so it takes up less space. Since there isn't any gas needed, you dont have to worry about any fluids leaking. It does weigh over 40 pounds, but it doesn't matter because of the self-propelling mechanism. I highly recommend!

                            [This review was collected as part of a promotion.] Rubber part fell off the back of mower about 2 minutes into first mow. Metal rod now hanging down, bent. Other than that, mower is fine. takes some getting used to with the self propelled delay and engagement, but shouldn't take too long.
