Product Details

The RYOBI 40-Volt HP 21 in. Whisper Series Multi-Blade Push Cordless Lawn Mower delivers the power of gas with cordless convenience. The premium HP brushless motor provides more power, longer runtime, and a longer motor life. It starts with a push of a button and is ideal for yards up to 3/4 acre. It features dual active battery ports and (2) 40-Volt 6.0 Ah batteries that provide up to 70-minutes of runtime. Part of our WHISPER SERIES family, this mower is among our quietest range of products. RYOBI's CROSS CUT multi blade system offers 2 blades for superior cutting performance. The integrated mulch plug allows for a quick switch from bagging to mulching with a pull of a lever. The on-board fuel gauge shows the status of the battery life remaining, making it easy to check while mowing. The durable 21 in. deck is lightweight, resists corrosion, and is covered by a limited lifetime warranty. The mower has a premium 11 in. high wheel design and the deck features 7-position single point height adjustment to easily select your grass height from 1- 4 in. With the 3-in-1 mowing functions, choose between bagging, mulching, and side discharge. An easy lift bag removal allows you to quickly and easily empty the grass bag. The 1-touch aluminum handles fold to help provide compact, vertical storage. This mower includes a 40-Volt rapid charger that charges batteries 4X faster than the standard charger.

          Great tool
          [This review was collected as part of a promotion.] We got this a couple days ago, I was using it and it’s easy to use, lighter then I thought

            Best Lawnmower I’ve Owned
            [This review was collected as part of a promotion.] Having a self-propelling lawn mower has made it easier to cut the grass. Also, I love that it’s completely electric.

              Easy To Use and Cuts Great
              [This review was collected as part of a promotion.] Great Idea of getting rid of the gas powered mower. The mower is much easier to operate, less issues and problems and cuts Fantastic. I can cut my entire yard with the two 6ah batteries I have, they charge fast and easy to put in and replace. Ryobi makes a Quality product and so far after 2 months of use I'm very very pleased and would recommend this product for any home owner, love the all wheel drive, it will go anywhere and through anything. Great Job Ryobi.

                  Best Mower I've Owned
                  [This review was collected as part of a promotion.] So quiet! No more gas/oil in my garage. It mulches perfectly, even hiding big Magnolia leaves where they can re-nourish the lawn. But I can also bag the clippings and use them to mulch my trees. I pick it up easily using the loading handle, and put into my car trunk for transport to another house, or stand it in a small footprint in the garage. Easy to clean. I doubt it will ever rust. It never stalls. Just push the start-button.

                      Everything great!
                      [This review was collected as part of a promotion.] I got this for Christmas and everything is great about it. It looks great, starts right up, easy start, you can use it as a mulching mower or use a bag, folds up and stores easily. That is the most convenient. We have two cars and a motorcycle, and we are able to fold it up and hook it to the wall. It is just perfect. Oh, and the battery has a button on the side that you can push to see where the charge level is rather than wait for the battery to die or wonder how much charge is left. Just perfect.

                        Easy mower
                        [This review was collected as part of a promotion.] The engineers on this found ways to make a rather complicated adjustable machine easy to operate. The one adjustment that took me a bit to make was the thumb press to ‘go’. But once it was adjusted (set where I can use my PALM rather than my thumbs), my hands were comfortable. The rest of the adjustments, and there are many, were intuitively…you can easily see how to make them. The 2 40V-6ah batteries included charge quickly. Both batteries have a compartment in the mower, but the key determines which battery is powering the mower (only 1 at a time). I give 5-stars for operation. As for ‘mowing’, I can attest the mulching feature works wonderfully (with 2 blades). So, for cutting, I also give 5-stars. As I said, the features/adjustments are intuitive, but there are instructions; but they’re not real easy to follow, with all the graphics for all the features on ONE fold-out page. This is an excellent mower!

                            Great so far!
                            [This review was collected as part of a promotion.] I recently bought this mower to replace an EGO that has been leaving me quite frustrated with an uneven cut, random long blades here and there, using the self-propelled feature seems to add a bit of "lift" to the mower, which means you have to set the mower lower than you actually want to cut your grass. The EGO is long and the bag is low, which, in turn, means it's constantly hitting landscaping bricks, low voltage lighting, etc. This Ryobi, however, seems to have THE BEST design. It cuts even, it's a heavier mower, which means straighter lines, better suction when bagging, no jumping all over the yard, and a more ergonomic handle. Another bonus is that the self propelled feature doesn't sound like a little kid's power toy. Thus far, I am thrilled with my purchase... this mower is definitely a cut above the EGO (IMO).
