40V HP Brushless 21" CrossCut Self-Propelled Mower with (2) 40V 6Ah Batteries and Charger
40V HP Brushless 21" CrossCut Self-Propelled Mower with (2) 40V 6Ah Batteries and Charger is rated 4.7 out of 5 by 287.
Rated 5 out of 5 by from Great cut, long cut time, great machine I received the mower and was immediately blown away by the quality of the build. The first thing I noticed was that it did come with 2 batteries and they were ready to run right out of the box. The only downside is that you have to manually switch which battery is active but all that takes is a simple flick of a switch. I was able to cut my front yard which was overgrown, and half of my overgrown back yard on one battery. It took the overgrown grass and weeds like a champ. I decided against the mulching bag and this thing chopped up the grass so fine. It really did a good job, excited to see what Ryobi can continue to do for the future!

Rated 4 out of 5 by from Quality Mower at a Decent Price Spring has arrived. I needed to upgrade to a larger 3 in 1 mower as my previous mower was lacking features and somewhat under powered. Going fully electric had not crossed my mind until I can across this mower. I was impressed with size and power it offered along with the fact that it included two batteries rather than just one. This was excellent news for me since I have just over a half an acre to mow. It's an impressive machine capable of cutting even thick, wet grass with out much of a struggle. I may never go back to gas powered lawn equipment after this. Definitely recommended if anyone is looking for power and longevity.

Rated 5 out of 5 by from Ryobi HP for the Win!! I upgraded to this mower from my old Smart Trek. Wow, what an upgrade. The paddle self propelled system makes turns a breeze in comparison to my old unit. Two batteries and a rapid charger gave me more than enough juice to get through the mow. The bagger was able to hold more as well giving me longer between empties. I wish the battery slots were both active rather than using a key, but I realized after a few uses this didnt really matter. Also worth mentioning this unit looks sweet and is certainly an eye catcher. Ill be checking out the other HP 40-Volt products for sure!

Rated 4 out of 5 by from Great mower, but could use improvements Bought this mower last week and have used 2x. Mows much better than Toro gas mower ever did!!! Do not understand why "lights" stay on. Waste of battery and bulb lifespan. If to indicate mower is on, then put red light on top. Needs to be heavier in front! Put batteries front to back rather than side by side, or better yet make front wheel drive. Rear wheel drive is a pain. Started not to even buy because it was rear wheel dr. Battery life is questionable for 3/4 acre. Have 1/4 acre lot with over half in house, DW, sheds ,etc and is taking all of 1 battery and little of the second. Still would strongly recommend this mower!

Rated 5 out of 5 by from Great mower, plenty of power and easy to use! I got this mower about a week ago and just got to test it out. Right off the bat I can tell it’s super sturdy and comparable to my previous mower that was gas powered. Speaking of gas mowers, I love the push button start on this one and I’m glad I don’t have to deal with the pull start anymore. Even though it’s a pretty big mower, it folds so storage has been really easy. Doesn’t take up much space in our garage at all. Doesn’t hurt that it looks nice too! My favorite feature is the Smart Trek technology that allows the mower to adapt to my walking speed. This makes mowing smooth and easy!

Rated 5 out of 5 by from Powerful and easy to use This is actually the first mower I buy. I have a pretty big lawn right now and was little overwhelmed, so I went with the most powerful of the mowers. I was pretty impressed with how easy it was to use due do its power and self propelled feature.

Rated 1 out of 5 by from Does not cut all of the grass!! I spent the extra money for the crosscut hoping to have a nice level grass surface after a mow. This mower is terrible. It leaves lots of blades uncut and frankly makes the lawn look ragged unless you go over it multiple times. For a $600 mower this is unacceptable. I don’t have time to mow my lawn twice each session to get a smooth cut. I previously had a 16” ryobi mower and it did a much better job. The 21” crosscut is a gimmick and clearly has not been effectively field tested. The battery power and run time are good, but that means nothing since I have to cover my lawn twice. It doesn’t matter how high or short I cut my lawn or how high or short the lawn starts when I cut it. Extremely frustrated and would not recommend.

Rated 5 out of 5 by from Cutting Is Fun Again Take the dread out of cutting grass. This new Ryobi mower is a pleasure. With the self-propelled feature, it was like strolling behind the mower. I was impressed with the ergonomics of the control handle. My old gas mower was like stretching your hands wide open just to grip the power and propelle control bars. And the speed control at your fingertips make this a breeze to operate. Of course the old days of pulling the cord until your arm hurts, are over. Push button start and runs quietly. I do believe my favorite feature, beside lithium power, is the single handle, all wheel adjusting bar. I can cut my yard and only use one battery. Convenient fold away handles allow you to store neatly away in the garage. So overall I give it a Five Star rating.
