Questions & Answers

Does this work on slopes yards?

The smaller cheaper mowers are listed as suitable for uneven or sloped terrain so why couldn’t this one handle it?
Asked by: Eric
Hi, Eric- Thanks for the question. This model will handle sloped terrain of up to 15 degrees slope. We hope this helps!

If I wanted to buy a 2nd battery, would I have to buy a 6.0Ah battery? If not, please provide a list of other batteries that would be compatible. Thank you.
Asked by: AM
Any 40 volt Ryobi battery will be compatible. The higher the Ah (amperage hours) the longer run time the battery will provide before needing to be recharged. The larger amperage also translates to a longer charge time.

Where can you buy a replacement 40v 6.0 AH battery like the one that comes with this mower? I checked even Ryobi's website, and it does not look like you can purchase a replacement. I can only find the 40v 5ah. As such, why is this lawn mower's components not supported like other models? What other component is exclusive for this device only, and if it breaks can't be replaced? Thanks.

21 in. 40-Volt Brushless Lithium-Ion Cordless SMART TREK Self-Propelled Walk Behind Mower with 6.0Ah Battery and Charger is rated 4.8 out of 5 by 4.

My husband is already loving this mower and is ready for spring to come in Michigan. This mower arrives with very limited assembly involved. The key start is great and easy to use. It comes with a new type of charger and one that took about 24 hours to charge for the first time using. Our other RYOBI battery worked just fine and we were able to test out the mower right away. It is very easy to push as the self propelled option works great, but the mower can also be used without that feature. It is very easy to change the cutting height and very easy to maneuver. My husband ran it over the lawn to test and it was cutting just perfectly. Bagging the clippings or mulching the clippings are both options. This mower is of metal construction and very well built. This is not an all plastic model. The handle adjustment is also great, as my husband is 6'4". The whole design is upscale and it is great to be ready for spring.

The Ryobi 40 volt 21" smart tech self propelled mower is designed to deliver gas like power to match the user's walking speed while maintaining an optimal cutting speed. It has rear wheel drive, weights 79 pounds as similar to my Honda gas mower that I normally use to cut the same area that weights 84 pounds. The Ryobi includes a 40 volt 6 Ah battery and charger. The on board battery compartment has a place for a backup battery that could be purchased separately. The mower can mulch or bag or with an optional accessory, side discharge. The front wheels are 8" and the rear wheels are 10". The battery should be stored at about 30 percent and was shipped at that level. It took 6 hours to bring the battery to full capacity. The motor sound and the motor running only occurs when the blade is turning and that will not happen unless the handle is fully extended and locked, the bag or insert in place and the start button depressed. The handle is 45" from the ground and higher than other gas mowers and will not run if shortened. My neighbor at 6' 4" said it was OK for him but it may be too high for some others. When you push down on the handle it moves the mower forward but instead of it being a smooth drive it jumped forward then stopped. It was difficult to make it move at a smooth walking pace. The cutting speed for the most part remained the same but sometimes slightly fluctuated. I tested it on my 60X100 lot that just needed a trim. It has a few slopes but is mostly flat. The mower ran exactly 40 minutes and cut the area satisfactorily. If I wanted to do my other lots I would need an additional battery or wait for this one to charge up whereas with the gas mower just continue on. I recharged the battery once again to full capacity, which took 5 hours. This time I did some neighbor's yards, one of which had a mound area that was 2' taller than the other parts of the lawn. The lawnmower easily climbed up to the top and around the sides. The mower ran exactly 36 minutes. I dusted it off as you are not to spray water on it. I then brought the battery up to 30% ready for next use and recharge. It can be stored in a horizontal position or vertically and the handle folds. The feature I really like is the 7 position single point height adjustment that allows you to select the mowing height with one motion on all 4 wheels. A neighbor only wanted his cut to 3" and I had to raise it but with this feature it was easy to change to any desired height. You have to plan ahead to use the the mower and charge the battery before use. The mower is environmentally friendly and no gas!

Ryobi and The Home Depot now have the perfect 21 inch lawn mower for your yard. With it's ability to mulch or bag, it is good for all seasons ! The height adjustment is one hand operation ! The "Self-propelled" mode is controlled by, how fast you can walk, with the pressure on the control handle. It also rolls without self-propel to get at the tricky areas, like next to shrubs ! The 40 volt/6amp hour battery is good. The lights make it good for mowing at sundown !! I wish it had 2 batteries ! I highly recommend this mower !!

Rated 5 out of 5 by from Ryobi 21" 40-Volt Brushless Lithium-Ion Cordless Smart Trek Self-Propelled Mower with 6AH Battery... Ryobi 21" 40-Volt Brushless Lithium-Ion Cordless Smart Trek Self-Propelled Mower with 6AH Battery is awesome! The directions were good. It comes with a quick start guide to. The mower itself has directions/reminders inscribed on the mower. I put the battery on to charge around 1700. It was still charging at 2400, bedtime. The next am it was charged. After first use it only took 4 hours to recharge. It weighs less than a gas powered mower. Which, along with the smart trek makes it easier to maneuver around, and mow. Prior to use handles must be fully extended, and locked. The battery has to be in the left bay, looking down at mower. The handle seems high extended, and locked. But, once you push down to mow the handle lowers too. It is amazing how this mower adjust to each person mowing with no, to minimal effort. Initially my spouse tried it without the self-propelled. He did a couple of rows and it was slow going, and bogged down a few times. Once he turned on the self-propelled it ran smoothly. Again, it goes as fast, or slow as you go. Our yard is a mixture of grass, Fl weeds, and fine brush encroaching on the yard. It is around 12,000 sq. ft.. Right now it is sparse. It mowed all but a couple of rows in the backyard. We have a couple of 40-V, 2.6 AH batteries from our blower, and weed eater. We just threw one of those into the mower and got the job done. We feel if we had it in self-propelled the entire time we could have finished with the 6AH battery alone. The blade is sharp, and works good. The light is a nice bonus. I wish we could turn it off during the daylight hours. But, it will be great to have when caught outside at dusk mowing. Initially, I thought the wheels looked flimsy. But, they are made of the heavier duty plastic. And with the rear-wheel drive the wheels moved right along, no issues. It comes with a bag, and mulching plug. It works great with either one. Nice that a choice is provided. We will be ordering the side discharge accessory. The mower is brushless, and provides the power needed to get the lawn mowed easily. As with any new product there is a learning curve, especially with all the great features. But, once you read all the directions this mower is so easy to adjust, and use it is absolutely amazing!
