Questions & Answers


is there a roll over bar that can be purchase for this model

Asked by hawksbooks April 9, 2021

Plus, Ryobi states that this mower should not be used on grades greater than 15 degrees and never be used across the face of a slope. Following this safety guidance should eliminate the need for a ROPS on this mower.

What is the top speed of the 100 Ah model? Thank you.

Asked by Mj March 28, 2021

I think it is like 6-8 mph. Not fast by any means but more than fast enough when cutting the grass.

Can I use a Cyclone rake with this mower?

Asked by JP March 18, 2021

Hi JP, According to Cyclone Rake, when asked if the Cyclone Rake will work with my garden tractor or ZTR mower, they post the following response: The Cyclone Rake will fit just about any tractor or riding mower, even ZTRs, as long as the mower deck discharge is on the right hand side (as seen from the driver’s seat). Remember, we custom fit every Cyclone Rake to your specific tractor which ensures maximum collection power and performance. If you have any questions about the connection to your tractor, call 888-531-7253 and we will put you in touch with our Cyclone Rake installation specialists. Sounds to me like you have a good chance that this will work, however, I would recommend calling them to be certain.

Asked by Jamis March 14, 2021

OK, I think I answered this one myself. The part numbers for the seats for both mowers are the same. The seat on the ZT540 has two arm rests bolted to the seat frame. If one wanted arm rests for a ZT480 mower, they could go to an authorized Ryobi service center and order the two arm rests to add to the existing seat.

Is there a good substitute battery for these? I live in Oklahoma and lost power for several days ...

Asked by BrianH March 7, 2021

An additional thought on the batteries not being connected to a powered charger for several days. Leoch states that these batteries should last for up to three months months before they will self discharge below a chargeable voltage. Unless one or more are failing, a few days should not be a problem. Still think the individual charge and load test procedure is the best tactic to persue.

If you do happen to hit a rock or other item hiding in the grass, can that damage the motor tha...

Asked by GaryLynn March 4, 2021

More than likely you will just bend the blade, which I have done about three times with no damage to the motor.

Does the width of 49 inches include the discharge shoot? I need to access a 4' gate.

Asked by Lawnboy March 3, 2021

The 49" width is with the discharge chute raised or held up, according to Ryobi. It is a tad less, but fitting through a 48" wide gate may be iffy.


Asked by DAVE February 22, 2021

What sort of UTV? There are several different styles from sports field utility to off road types. Are you thinking of the styles Club Car makes or the off-road side by side ones like Polaris makes?

Which has more power (for mowing tall weeds), the Ryobi 42” Zero Turn or the Ryobi 38” Tractor?

Asked by Festus January 27, 2021

Festus, thank you for your interest in the RYOBI 42 in. 75 Ah Battery Electric Riding Zero Turn Mower. Both of these models should be able to handle the job you have described. You will likely need to start at a high setting and work your way down with two or more passes. Thank you for asking, If you have further questions and would like to speak with a RYOBI Customer Experience Professional, please call, 1-800-525-2579 M-F from 9am-6pm EST. Hope this helps! - Vini

almost fits the bill,but not quite for me
Owned one week.Used in Queensland Australia Give this machine 4 out of 5 1. Does not cut nearly as well as my 20 year old husqvarna, tends to chew the grass rather than cut cleanly. Possibly swing blades rather than straight bar blades may overcome this problem.For this reason alone,I do not believe I will retain it 2.I accept that it is designed primarily for the USA market especially when it comes to complying with safety regulations, but the blades switching off when reversing,then having to go through a procedure each time to cut when reversing of re-activating the blades is a definite pain and a no no. 3. Build quality is very good 4. Seems like a somewhat top heavy sitting position, likened to sitting on top of a car rather than in it.Height adjustable steering may improve this 5. Length of Grass discharge chute excessive and not warranted. 6. Deck wheel axles with grease nipples would be a positive move.

Excellent mower
[This review was collected as part of a promotion.] I've been able to mow my acre lot with trees and hills and it still has 50% battery. Also mowed my neighbors lot that had grown to 6 - 10 in high, and it still had 25% battery left. Quiet and mows great.

This is my first ever online review and I very much hope to be able to change my recommendation when I can actually use the product. I was very excited to receive my mower as I had done extensive research prior to purchasing the product. Upon receiving it and putting the mower together I realized that my order included no charger (It is listed as including a charger). For a completely electric product this is of course a huge issue. After talking directly with 4 different people at Ryobi I was told that they are on back order on chargers and wouldn't be getting them in for several more weeks at least and there was no other option besides calling Home Depot directly and seeing if they had one. After calling Home Depot, I was told they have nothing to do with this process and that my only option would be to purchase another $4000+ mower and process a return for my current mower. All this by a representative that was mildly rude and disinterested in my issue from the beginning. I am super disappointed in the whole process because the mower itself looks and feels great but is completely unusable currently as we approach winter and I need to get a mow in on my more than 2 acres of new property. Perhaps it is asking too much for one of these companies to get creative and find a way to validate my $4200 purchase by providing a critical piece of the product I should have had the entire time. Hopefully this does not happen to you and the many positive reviews I read on the product gave me confidence in making this purchase, but if it does happen I would most certainly not expect a quick result out of it. Very disappointed with Home Depot in this as I have spent thousands and thousands of dollars over the last couple years and there is are other places to shop down the street.

Mowing just got a lot easier.
I was a little hesitant at first because I've always been a gas guy. After looking at the pros and cons and seeing all of the positive reviews, I gave one a test drive and loved it. I've only had the mower for 3 months now but I have consistently mowed twice per week since I purchased it. It is literally one of the toughest mowers I've ever owned. Its cut is consistent and the battery holds up wonderfully. We have a fire pit with stones around it and my son decided to move one of the stones into the grass to hold his phone while he made a video and of course left the stone there. My wife was mowing and ran right over the stone. The blade hit the stone and the mower instantly shut off the blades. One of the blades was ruined so we had to replace it but that was it. The drive motor for the blade didn't skip a beat, it's as good as new. There is so much less maintenance to do, no gas to buy, no fiddling with the engine to get it to run. You won't be disappointed. This IS the future.

I was diagnosed with carpal tunnel syndrome in both wrists a few years back, and it was getting harder and harder to turn the steering wheel on my John Deere lawn tractor. I had been wanting to get a zero-turn-radius mower for a while so I could push and pull the steering bars instead of turning a steering wheel. I finally took the plunge when the Ryobi 42-inch 75 Amp-hour electric riding zero-turn mower went on sale in May 2020. It arrived on June 3 and was in perfect condition. It took me about an hour to assemble it and drive it off the shipping pallet. Learning how to steer with the push-pull bars was an adventure at first, but I got the hang of it by using the slow speed setting, as recommended by Ryobi. I have to say, I wish I'd purchased a zero-turn mower a long time ago! Once I learned how to steer my ZTR mower, it was almost a pleasure to cut my grass! I live on a corner lot, so I had to drive my old John Deere out into two roads to turn around at the end of a row. But my Ryobi ZTR mower turns on a dime and eliminates that danger. Also, the new mower has cut the time to mow my yard from about 60 minutes to about 35 minutes. I couldn't be happier with my purchase, and I would highly recommend this mower to anyone who wants to take significant minutes off the time it takes to cut the grass. The only thing that might eventually concern me is cleaning the mower deck, and it's really only a minor concern. Because the mower is electric, I can't use any water to clean the underside of the deck. I actually haven't cleaned it yet, but I'll see how it goes when the time comes. I liberally sprayed a teflon-style non-stick spray onto the underside of the deck, the blades and the discharge chute before I cut the grass the first time, and so far it seems to keep the grass from building up too much. So I really have no complaints at all about this mower. Again, if you're thinking of getting a ZTR mower, this is the one. No gas, no oil, no exhaust. Just plug it in, charge it up, and go! Well done, Ryobi!

Easy to put together and comfortable seat. Cut is clean and battery lasts longer than online reviews estimated (cut over 2 acres with 55% remaining). Super simple plug in - very happy to stop hauling 5 gal. gas cans! Three items that warrant consideration: The front end is not weighted down (no motor after all) so if the driver is lightweight it bounces on bumps and slopes; you can't start it with your foot on the brake so if you stop on a hill for any reason you are stuck there; if it has no traction (wet grass, moss, mud) it won't even try to go forward or backwards so, again, you are stuck. I slid on a hill at edge of my lawn and stopped. But I needed to keep foot on brake to avoid winding up in bushes so then it would not start and because I am lightweight it could not get enough traction to go once I got it started. Wound up pulling it out with my tractor. Best for flatter lawns and heavier drivers. And Ryobi - the sexist safety warnings on the key fob do not endear 50% of the population to your company. Yes, women mow lawns too.

Wow. This thing is amazing! Finished in 30 mins the area that my old conventional tractor took 1.5 hrs to complete. Then tackled an area I hadn't mowed since last year (lots of tall stuff) and it blew through that with no problem. Plus a little more cleanup for a total of an hour. Drove it back in the garage with 70% charge left! GOOD BYE, gas and oil!!

In May 2018, I purchased the Ryobi Riding Mower, as we had just purchased a home with a large yard and I am very into the whole electric thing. I do not own anything gas powered. My car, lawn mower, bike, tools, etc. are all electric. I hate dealing with gas and oil and spark plugs and belts. Yada, yada, yada. The convenience of electric is so incredible and nowadays, they are more than powerful enough for all of your needs. At the time I purchased the Riding Mower, I was looking for a Zero Turn, but it didn't exist (yet). April 2019 rolls around and sure enough, Ryobi came out with a Zero Turn Electric Riding Mower... so I bought a 2nd Mower. lol. I ended up selling the Riding Mower at a minor loss, but in the end, it was well worth it as I got the product I ultimately wanted. I like to think of the loss I took on the Riding Mower as my rental fee for that first year. Regardless, the fact that I owned a Ryobi electric Riding Mower for a year and then spent several thousand on a 2nd one is a testament to the product line. The Zero Turn Mower is fantastic... all of the things I had hoped for. As with any Zero Turn, it takes a mow or two to get the hang of driving it, but after that, it's second nature. The machine itself is built very well. It comes delivered on a steel pallet and there is minor assembly (attaching the handles and seat). My only gripe with the construction is that the sides are made of plastic. Sometimes, when sitting down and getting situated on the mower, I will use my hand to lower myself down. The only place to put your hand is on the plastic part, which you can feel bend a little bit. If it were all metal construction, I could easily lean on it without fear of breaking anything. Other that that... the machine feels very solid and performs very well. I am able to zip back and forth around my lawn and cut with ease and my lawn looks amazing. No missed spots or weird patches. I make a point not to cut wet grass, as is just good practice with any electric mower. I do have an ongoing issue with the battery meter. After my first few mows, the meter stopped showing 100% when fully charged. It would top out at 70%. I called Ryobi, as they said it was probably just the gauge and they shipped me out a new gauge. I swapped it out and initially, it read 100%. Sure enough, after the first mow, it topped out at 70% again. At this point, Winter was coming, so I packed it away for the Winter (plugged in) and planned to revisit it in the Spring. Spring came and it was doing the same thing. Since the battery warranty is only 1 year (the rest of the unit carries a 3 year warranty), I wanted to get this addressed ASAP, as I feared it was a battery issue. I called Ryobi back and they referred me to a local service center, who came and picked the unit up from me for evaluation. Upon inspection, they said they couldn't find anything wrong with the batteries, and acknowledged that the gauge was sporadic. They ultimately replaced the charger for me (I think they just wanted to be able to say they did SOMETHING). Sure enough, the problem persisted. I ultimately stumbled upon an online forum where other people were reporting the same exact thing. It appears that the gauge just isn't very accurate, but doesn't ultimately affect the battery. When I'm done mowing, my mower will say 25% remaining. I let it sit outside while I trim and then come back to it to blow it off with the leaf blower before putting it back and plugging it in. When I come back to it, it then reads 45-55%. Clearly, the gauge just can't get a real-time, accurate read on the true battery status. That part was very frustrating, but in the end, it doesn't really affect the actual performance of this machine, so I can look past it as long as I know that I didn't get bad batteries. I've never run out of juice while mowing, so that's ultimately all I care about. I don't really use the lights or the phone charger, so I can't really comment on those, although I tested both and they both seemed to work as they should. I have tried hooking a small tow cart (8 cubic feet) up to the hitch mount in the back and was able to tow that around without any issues. I towed stuff back and forth from the garage to the shed and even sat my wife in the back and pulled her around without any issues. I also ended up buying the bagger for this unit, which I am also very happy with (the bagger isn't perfect, but works as it should - please see my detailed review on the bagger page for more details). Overall, I would definitely purchase this unit again and wouldn't have any problems recommending it to a friend. I really enjoy the ease and freedom of electric. Obviously, this wouldn't be good for commercial use, as you would definitely run out of juice after 2 or 3 jobs... but for standard homeowner use of an acre or so, it's perfect.
