Rated 4.3 out of 5 by 375 reviewers.
Rated 3.0 out of 5.0 by Ryobi 40 V mower I had my mower for 2 years. It is just adequate to do my lawn. Nice and light with no gas or extension cords. The 2 original batteries I needed to get a 3rd one to do my lawn in 1 session. There is a defect in 1 of the original batteries getting stuck in the battery slot.. Twice I had to take it to a service center to take the mower apart to get it out. In spite of shaving the slot and the tab on the battery it happened again and I had to pay for the service. So far no solution from Ryobi! June 18, 2015
Rated 5.0 out of 5.0 by Great Buy We needed a new lawn mower and wanted a cordless one. This Ryobi 40volt lawn mower is great. When we got home unpacked it out of the box, connected the handle plugged in the key and battery. The single-lever hight adjustment was easy to use, cut the front grass with ease, handles great. Easy to remove the rear bad to empty. This mower is perfect for any lawn. May 25, 2015
Rated 5.0 out of 5.0 by Breathe Easy This mower has replaced our still functioning gas mower, and we think it was a wise choice, our lot is a standard city lot in Bigger City of Sudbury. Grass was 2 - 21/2 inches and one battery cut front, back and front again, with no problem what so ever. No gas fumes to choke on (love that part) and starting it up is a snap, light weight easy to maneuver and makes mowing the lawn fun. The people at Home Depot were very helpful and informative, they are great. May 18, 2015
Rated 5.0 out of 5.0 by Great product, excellent for small backyards This product works very well on small yards due to its portability and size. It is very quiet when running and the included batteries carry a very big charge, would recommend. May 29, 2015
Rated 5.0 out of 5.0 by Ryobi 40 volt lawn mower Excellent operation. Light weight, excellent height adjustment , quiet and easily stored. September 2, 2014
Rated 4.0 out of 5.0 by Pretty good so far Just bought this at home depot. Right out of the box, this mower looked realy good. Unfolded it, put the battery and key in and it started right up. I was able to do my front yard, which is by no means huge, with only about 1/4 charge on the battery right out of the box. It definitely doesn't have the same cutting power as my gas mower, but that's to be expected. The nice part is no pull start and VERY low vibration compared to the gas. That's good since my shoulder is messed up and pull starting the gas mower was really hurting. My lawn isn't huge here in the city so this does the job perfectly. I'll be surprised if I even need to break out the second battery to get both the front and back done. It will be interesting to see how it works on grass that has been allowed to grow a little longer than normal though. It might take a couple passes at varying heights to get through it. Also be interesting to see how it handles (if it can) wet grass. June 4, 2014
Rated 5.0 out of 5.0 by RYOBI 40 Volt Lawn Mower Great lawn mower. It was very easy to assemble and does a great job of mulching (use length setting 4). The Ryobi is light, easy to use and does not hurt my back. One battery does my front and side yards. The second battery is required part way through the back yard cut. Charging time is around two hours. The two battery system should give you 70 to 80 minutes of cutting time. I highly recommend this lawn mower. April 26, 2014
Rated 4.0 out of 5.0 by Quality control? We recently downsized to a smaller home with only a small patch of lawn. My gas powered mower seemed a bit of overkill therefore wanted a smaller, lighter mower preferably battery operated. Owning several lithium battery power tools, which are excellent, I chose this model. Unfortunately when assembling out of the box I couldn't get the handles to lock onto the mower. On closer inspection it seemed the nuts were seated in the wrong slot making it impossible for the clamps to work. My choice at this point was to either return the mower (1/2 hour drive) or fix it myself. After a bit of a struggle removing the plastic cowling I was able to reach the nuts which had been jammed into place outside of the proper location (factory?). Fortunately no damage done and once seated properly was able to lock the handle. The mower works well, is quiet and handles easily. Battery charge is adequate and recharge as with most Lithium batteries is relatively quick. So far pleased with the product except for the glitch. I plan to let the store/sales associate know on my next visit. May 29, 2014
