40V HP Brushless 21" CrossCut Self-Propelled Mower with (2) 40V 6Ah Batteries and Charger
40V HP BRUSHLESS 21" CROSS CUT SELF-PROPELLED MOWER KIT is rated 4.6 out of 5 by 691.
Rated 1 out of 5 by from It will not Last - Plastic base Within a few month of purchase the blades began to hit the side walls. at first this was minor and intermittent. After 6 months of light use on a small flat and well kept lawn the blades began to hit the side 80% of the time and causing excessive noise and vibration. In addition to this at the six month point the batteries would fail intermittently with two of the middle lights blinking. I sent the mower and batteries in for warranty work and they returned the mower four months later without the batteries. They said there was nothing wrong and the blades were not hitting the sides. You can see from the picture the deep gouges in the sides. Money would be better spent on another brand or an engine driven mower.

Rated 5 out of 5 by from Another great Ryobi product! My old gas mower was always a challenge in the spring to get started. So after research I decided to make the switch. This is always my go to brand for 18v tools. I just didn't know if I was ready for the 40v lineup yet, because i didn't own any or know anybody that did. Im so glad I switched from gas to this! I purchased all the 40v yard tools and got rid of all my gas powered equipment. Most of the time 1 battery will do the job, I can switch it from the weed trimmer/edger attachment to mower to blower and still have power left on the one battery! When using the mower for leaf pickup I actually heard the mower using more power as it needed for the thicker spots and it never struggled. This thing is amazing! Storage is so easy, just fold the handle and away it goes. You can even use the self propelled function without engaging the blades, incase you live on a hill like I do or just want to have it do the leg work for you. If your thinking of making the switch you won't regret it!

Rated 5 out of 5 by from Great quiet mower! I got this mower a little early for Christmas and used it a couple times so far. It is awesome! It’s quiet and powerful. The batteries didn’t take long to charge and they held their charge the full mow. Great mower!

Rated 5 out of 5 by from THE LAWN TAMER This lawn mower is impressive with its dual blades and self propelled it easily cuts through grass as it climbs up and down my sloped front lawn The dual blades provide a nice cut making the grass look like well manicured turf . Its lightweight and easy to turn, roll, fold and store. I wish I would have bought it sooner.
