40V HP Brushless 21" Self-Propelled Mower
40V HP BRUSHLESS 21" SELF-PROPELLED LAWN MOWER KIT is rated 4.7 out of 5 by 791.
Rated 5 out of 5 by from Great mower This is a well designed mower. I love that the handle folds up and mower can be stored against the wall. Comes with 2 batteries. I can mow my front yard and all around my pool in the back on one battery. Super quiet and cuts well if you don't ask it to do too much.

Rated 5 out of 5 by from Everything I expected I bought my Ryobi battery mower in May of this year. I am completely satisfied with the performance. Plenty of power, good battery run time and most of all a pleasure to use

Rated 5 out of 5 by from Better than my EGO SM2135 For years wasn’t having ego fans. I still believe in their products, however, we will be has taken a lead far as quality and innovation. Very pleased with this long war bags better than the ego in the handle height adjuster shifts way. Easier you only need literally one finger to adjust it. Holding the handle is easier than eagles too. Highly recommend.

Rated 5 out of 5 by from So user friendly Could not be happier with this mower. So so easy to operate and it works great. Neighbor warned being battery powered it would not be able to cut the thick parts. Not true. It did just fine and the batteries really had staying power. I was very nervous about buying a battery powered mower, no more. I won't mention the joy of not having to buy gas or oil for the thing.
