Rated 1 out of 5 by from Wouldn't start after coming New out of box I bought this two weeks ago from Home Depot. Upon unpacking, setting up the lawnmower, and charging the battery completely, the motor barely kicked over and only the light would turn on following. I attempted to troubleshoot the problem by removing the battery and key, removing and inserting the rear plug, and collapsed the handlebars in case it was a cut-off sensor issue, yet only the light would come on following. Who knows how long it was sitting on the sales floor? Currently waiting to hear back from Ryobi on returning it for repairs or replacement.

Rated 5 out of 5 by from Beyond Expectations I’ve had this for three months. I had a Honda 21” cut that I had for 9 years. Poor girl was getting tried. Did a lot of reading and it pointed it to this mower. I have the Ryobi cordless weed eater edger blower etc. the thing I love is it will cut the lawn twice on on charge. I bag the back yard. Cause it’s where the grandchildren play. It does a great job and I mulch the front yard and it does as good as the Honda. I got the self propelled but the mower is so light I rarely use it. Love the clean inside mower deck no grass accumulates and I store it in the garage. The Honda was stored in outside shed. It’s so quiet I look forward to mowing now

Rated 5 out of 5 by from Great mower for smaller lots! We own slightly more than 1/8th of an acre of very hilly land. Backyard is flat, but front yard has 7’ of elevation change from curb to front door. The self propelled feature gets me right up the hill without hesitation, is variable for a comfortable walking speed for me, my wife and kids even. It’s super quiet compared to a gas mower. I could have a conversation at a slightly elevated volume while it was running without issue. Didn’t wake up a sleeping infant while mowing the backyard with her on the porch not 30’ away. The self mulching feature is great, no bagging and no piles of clippings all over the lawn. Folds down into a small footprint for the cramped garage or shed people. Overall a great product, typical Ryobi durability and value!

Rated 4 out of 5 by from Very good mower My wife bought me this mower because she hated the gas fumes from my last mower. I really hated to give up that mower but this one is good. It does the job almost as good, there is no gas smell, and it is very quiet and powerful. I am impressed with how much grass I find in the bag after mowing the lawn, it catches much more than it seems. It has a nice fold up feature so takes up less space in the garage. The one issue I noticed was the handle seems a bit heavy, I have to consciously make sure the front wheels are on the ground. It's an easy adjustment. I like it and expect to have this lawn mower for many years to come.

Rated 1 out of 5 by from Great if You Enjoy Mowing Ten Seconds at a Time Bought this today, got it all charged up and working, then went outside to mow my lawn. I decided to use the mulch plug because I don't want to bag the lawn right now, but it doesn't fit correctly. I thought it was in place, but after a few starts and stops, I realized that the mulch plug was getting un-seated by the vibrations of the mower. No amount of pushing or pulling will get it to sit correctly, so you can start it, get going, then about five to ten seconds later it'll just stop itself. I sure hope I win the Home Depot Gift card contest so I can buy a different mower and actually cut my grass.

Rated 5 out of 5 by from quiet I purchased the 40 volt self propelled lawnmower on June 3, 2020. Had a few problems in the beginning. Battery defective and mulch device did not fit correctly. I returned both to Home Depot and they promptly replaced. I am happy to say I have been using the lawnmower ever since and I am very pleased. No more gasoline or oil to contend with, just charge and go, and it is very quiet. My neighbors are also impressed with the product, so you may have future customers. This is my 4th Ryobi product. I also have the snow blower, weedwacker and hedge trimmer. My next purchase will be the leaf blower. I am very impressed with the ease of using each product.

Rated 5 out of 5 by from Does an excellent job on the yard I bought this mower to replace an earlier model. What took 3, 4amp and 1 5amp batteries to complete my yard, approximately ≤1/2 acre with many hills and banks, with the older model, now I finished the lawn with 1 6amp, 1 5amp, and part of a 4amp batteries. Mowing at an easy pace the mower cut right through 7 inch high grass with a smooth even cut. The mower is much lighter than my older gas model and I'm pretty sure it weighs less than the other electric Ryobi I just retired with a broken handle. All said and done, if you have become tired of the maintenance on gas mowers and want an easier, better for the environment option, I definitely recommend this model.

Rated 5 out of 5 by from So far it's a great purchase! Tried the mower out for the first time this weekend on my tall bermuda lawn! It was also a little wet when I started! I got my height properly adjusted and everything went great from there! The mower was easy to push even w/o the self-propelled component engaged. I only used the self-propel mode going up the hill when I was done mowing after about 30min of mowing and it handled everything great! The grass looks fantastic and smoothly cut. I used the mower in mulch mode and everything was cut fine enough to not leave trails of clippings even though things were a bit wet. Overall, very happy with the purchase thus far!
