I want to onow if this lawn mover needs 2 batteries to operate? O only need 1 and the other one is for backup?

Asked by Humberto May 15, 2021

Answers

It only uses one at a time. You can keep both batteries on board and there is an easy manual way to switch between them if you have a lot lawn to cover, but my yard is small so I usually just run with one.

How does this mower work on steep hills?

Asked by Nick May 7, 2021

Answers

Mine propels itself up my neighbor's ~25 degree hill easily. Once up the hill, mowing across it works fine as long as you have solid footing. The unit is lighter in weight than my old gas mower and is not top-heavy.

Asked by halfsquatch April 28, 2021

Answers

I am 6'4 and it needs 1 more notch on arm for it to be totally comfortable, you might want to go in store and test. Others might be better/worse I dunno, but after using this I realize on highest setting it could still use to be a little higher to be more comfortable for me, it might be an issue with you being 6"7. But definitely self-propelled for your back 100%.

No, I don't believe so. This is a very heavy duty battery. It uses a different charger than my other Ryobi batteries.

Waste of money
Good if you have prefect flat even yard that looks the golf course thats already been mowed, or if you wanted to take it on the side walk. Picture is of grass 1inch long and the lawn mower could not handle it

Wheels Fell Off - Literally
I just purchased this yesterday after doing a lot of research and was very excited to try it out. Charged the batteries and followed the instructions and was ready to go. I started down the first row of grass and the right front and right rear wheels fell off. It looks like the hubs/covers were not installed. Not overly impressed. You can see the difference in the two sides of the mower in the pictures. Tag is still on the mower so it is right out of the box. Painful to have to now spend an hour or two sorting it all out. Hopefully they can rectify it quickly and I can cut the grass.

First Electric Mower
[This review was collected as part of a promotion.] Love this mower - really glad I took the plunge and went electric. Compared to the other cordless electric mowers I've seen, this one takes the cake and I am VERY please to have went with RYOBI. Battery life is a lot more than I expected honestly and I look forward to lawn mowing even more!
by rON1993
excellent mower
[This review was collected as part of a promotion.] After my 30 year old Honda started acting up i decided to make the switch to cordless, i was worried that it wouldn't handle all the things my old mower did, but WOW was i wrong! this Ryobi 40v hp self-propelled mower is amazing, it handled everything i threw at it well, including tall wet grass, i wish i had done this sooner, best of all, NO MAINTENANCE!
by Crickwood
Wow!
No more gas for me! Absolutely love how easy this mower is to use as well as how great it cuts. My yard looks like a golf course after I finished. Bring on summer!
by Happycustomer
Incredible bagging!
This mower is amazing! Highly recommend it for anyone who is interested in replacing their gas mower. It has a large bag and fills it to the brim with grass! Cut quality was outstanding too. Just under 1/2 acre and I had plenty of battery left over.

I was looking to convert from a gas operated pull start push mower do to a major surgery I had. I was reluctant about converting but once I used the Ryobi 21” for the first time I was convinced I made the right choice. It is well built and has the power and battery life I need to do my yard. After using it several times I gave my gas powered 20” to my neighbor. I have several Ryobi hand tools and very happy I added this mower to my Ryobi collection.

I’m in LOVE
This mower is the answer for me. No gas to buy and SO EASY TO OPERATE. I’ve mowed with gas powered self-propelled mowers forever and I got soooo tired of issues. I went to buy yet another one when i met the Ryobi rep in the lawn mower isle. She was very knowledgeable and convinced me that i needed to give it a try. I’m so glad i did and my lawn has never looked better. I highly recommend.

LOVE This Mower!
This mower did NOT disappoint! It has a sturdy feel and all the power you need to finish the job. The new folding handle release is so easy to use and the same goes for the new adjustable height lever! Incredible upgrades all around. First mow of the year was a success and I can’t wait to get back out again next week.
by Jhigdon13
The total package!
[This review was collected as part of a promotion.] This is the best electric mower I’ve owned to date, and consider myself converted to Ryobi’s line of tools. My two favorite features are the 2 battery system and the folding handle. Being able to mow the lawn in one charge and then store the mower vertically to save space is such a game-changer!
