RYOBI is leading cordless innovation with the introduction of the RYOBI 40-Volt 21 in. SMART-TREK Self-Propelled Mower. This self-propelled mower features SMART TREK technology that adapts to the user’s walking speed and has rear wheel drive for increased traction when mowing your yard. The brushless motor delivers gas-like power combined with load sensing technology that detects and delivers the power needed to maintain an optimal cutting speed, resulting in maximum power and run time. Featuring a 21 in. durable steel deck, this mower was redesigned with a 7-position single-point height adjustment (ranging from 1-1/2 in. – 4 in.) that allows you to select your mowing height with one single motion. Choose which mowing option is best for you with the 2-in-1 mulching or bagging capability, or the side discharge accessory sold online. When the job is done, simply remove the Easy-Lift Single-Motion lock and release bagger to empty your grass and place back down to easily lock it back into place. The collapsible step-to-release handles offer a variety of storage options for compact spaces. The 6.0 Ah 40-Volt Lithium Ion high capacity battery offers extended run time, and is compatible with all RYOBI 40-Volt tools. Backed by a 5-year warranty.

Used mine three times. I use it edge around the perimeter of my .67 acre lot and around trees. It takes about 15 minutes each time and I get two uses per charge. Use can turn the self propelled feature off, which can be useful in right spots.
Johnpaul Cormier (verified owner) –
After getting used to the smart drive I really like my new mower! It is lighter than my Toro Mow & Stow, so it is easier to handle. It gives a nice mowing to my very uneven yard. I went through a battery and a half charge the first mowing, so that is great.
Marlen Corwin (verified owner) –
It works well even on uneven ground.
Mae Wilkinson (verified owner) –
Mowed the front and back yard with ease. Still had 50% battery life. So far, no problems.
Claude Moen (verified owner) –
The box arrived badly dented with holes in it. One of the aluminum arms was scuffed up in shipping. The machine is heavy so the power propel is needed on this one. This has several safety locks to protect you. It mows well and the 6 ah battery lasted cutting my front and side yards on a corner lot. That was about 45 minutes. In other reviews I saw that others needed longer run times. I bought a Combo set that had a 5 ah battery and 300 watt inverter. This battery ran over 30 minutes to do my back yard. I also bought the fast charger and I am glad to have it as it charges twice as fast as the regular one that comes with the mower. I am still learning to use this mower and the longer I used it the better I like it. I do all the mowing and also use the small 16″ Ryobi push mower for trimming close to my curb, fence, and trees. It is very light and goes where this 21″ mower can’t.
Loy Mraz (verified owner) –
Easy to operate, did a good job with its first cut of the yard using the mulcher plug. Yard took about 20 minutes to mow, very happy with the mower so far
Letha Okuneva (verified owner) –
Love this mower, I was looking for something easy to start and low maintenance. This is exactly what I needed
Jalyn Hegmann (verified owner) –
It quits before I have my lawn done. And the batteries are wicked expensive!
Bartholome Walter (verified owner) –
Lightweight, cuts normal length grass just fine. Can be a little tricky at first to start since you have to have the handle set up correct, but after you have that down it is great. My daughter mows the lawn and said it is so much easier than the older gas mower we had.
Danny Schiller (verified owner) –
The battery should have slightly large capacity. Twice I just finished cutting the grass when it went dead; the last time I was not quite finished – had to fire up the old gas powered mower for about 3 minutes to finish the job. (only used it three times so far)
Vena Botsford (verified owner) –
I like the mower overall. It cuts well, rolls smoothly, is quiet, starts well and has enough power and battery life with 6ah to make it through my 1/3 acre lot. My only complaint is I will be mowing and it will stop running. I’ll release the handle and press start and it runs again. This will happen 6-8 times per mowing session.
Dustin Brown (verified owner) –
Easy to install, use, and store. One battery lasts more than enough for 2500sq yard.
Duncan Lindgren (verified owner) –
Easily put together, works great
Mikayla Strosin (verified owner) –
This mower is easy to assemble, to use and to store. Great for mowing larger lawns.
Lilyan Kuhlman (verified owner) –
cut grass good. easy to use.
Tony Leffler (verified owner) –
Well made and so far so good.
D’angelo Rippin (verified owner) –
So far so good. Battery lasts long enough to mow my 0.25 acre lawn. Headlights are very bright. Easy start and convenient storage.
Leanna Dibbert (verified owner) –
I bought this back in September of 2019 and really think it works great. I was worried about switching over from gas to battery-powered and have had no issues. I use about a battery and a half to mow about a 1/3 acre law and it does great. It also has variable speed mowing and power propel system so it always uses enough power to get the job done. I would highly recommend!
Iva Nikolaus (verified owner) –
Mowes well, very good in mulching mode. Battery has already, after 3 mowings of a small yard, begun to lose capacity. Too long to charge and the transformer et very hot. As I stated earlier in a post, the mower handles are too wide as are the wheel location. A serious design flaw. Impossible to mow close along a house or fence.
Keshaun Renner (verified owner) –
I’ve used this twice and each time it has been great. The adjustable height is easy to use and the ability to turn off the self-propelled feature is a plus. I’m very happy with my purchase, so far.
