This lawnmower lived up to expectations
The assembly was extremely simple and took about 10 minutes. Charged the battery over night and then mowed back yard. Used approx. 1/4 of battery. Although, the turf waoms not very high, the mower cut it as good as any other mower. I am satisfied with this purchased.Update: lawn mower has worked great for 1 1/2 years. However, the 6AH battery which came with the mower has died. Was half way through mowing front Yard when it failed. Indicator lights 1 and 3 work but lights 2 and 4 will not. This is true on mower or charger. The error indicator on charger is flashing. Ryobi will not honor their 3 year warranty if purchased through Amazon. Guess I am out $200 bucks.

Great product!
We’ve very happy with this lawn mower. It is light weight enough to use with ease. The battery lasts long enough for us to finish the job and we love that all that is necessary is to push a button to start it.

Outstanding !!!!!
My gas mower, 3 yrs old wouldn’t start. We decided it was time to add another Ryobi product at our house. We own a Ryobi Driver & 40v weed trimmer. We tried out our new mower & were Very pleased with how nice it cuts & did not have issues with battery running low. I meanwhile, put a new plug, air filter & fresh oil in my gas mower & it fired up. I am a 69 year old woman that was a mechanic 50 years ago . The new Ryobi mower will have the front yard & gas mower will have the back. I highly recommend the Ryobi 40v. I also purchased the extended power charged battery & With warranty registration , they send you a fast charger free of charge. A Win Win from where I’m standing.

an honest reviewâ¦..
Bought this product in march and started using in April, the box came a little beat up but everything inside was fine. Assembly was super easy. I used on my front lawn and it was great, moved to the back and did almost all of it then it died. But the battery still showed 2 bars. So I charge it up and tried again the next day. Now it will start and then die almost immediately. I tried over and over. Same result. I called RYOBI support and they do not accept returns bc this seller is NOT AN AUTHORIZED SELLER of RYOBI products. Maybe if I had bought it from the source I wouldnât have these problemsâ¦. But I was trying to be cheap. Lesson of the story, donât be cheap and DONT BUY FROM THIS SELLER!!!

This is an awesome machifne. No gas, oil, or pulling a rope to start it. I used mine to mow all the places i couldn’t get my Jriding John Deere in to mow, and it did a fantastic job. It is akso very easy to store and it takes uo only about one footawesome of space

This is an excellent mower.It is lightweight and easy to push: we have lots of hills and there is no need to add self propel. The battery lasts just over 50 minutes on a charge.Delivery was late and then went to Canada Post office so had to drive 20 miles to pick it up. Not impressed by that.
