    Ryobi RM480E 38" riding mower won't move!

    That was supposed to read 100 AH, not mhp.

    Ryobi RM480E 38" riding mower won't move!

    I would be curious what batteries people are going with. My batteries, or at least one of them, is bad and I'm thinking about upgrading all four of them to the 100 Mhp batteries and wondering if anyone has an Amazon link for what you found and that works.

    Hey, just sent it. Most likely the drive motor controller and/or the accelerator transducer. The transducer is only around $120 roughly (if I remember right), plus it is very easy to check. The drive motor controller was $300 something odd dollars. Since I replaced both it's been working great...

    Ryobi RM480E 38" riding mower won't move!

    So I'm hesitant to say my mower is back up and running, but for now it seems to be doing fine. I replaced the motor controller, the big symptom there was that everything else was functioning except it wouldn't move. I also replaced the speed controller (the part that goes on the pedal and...

    Hey if you pm me your email I will send you the Ryobi repair manual. It has how to check using a Multi meter, what everything should read

    After replacing the drive controller I was able to mow but it would stop after about 20 minutes and wouldn't go again until it sat for about 30 to 40 minutes. Went out the other day and it would go at all. Pulled the accelerator switch and tested per the repair docs and it's bad. Ordered...

    I wonder if what your experiencing now is from a bad or not connected heat sensor. Check this out (below). I believe this part comes off the connections from the charging port.

    Ryobi RM480E 38" riding mower won't move!

    Yes thank you. I looked it up online and understand now how that works. The hall sensor can stop the motor from running by causing a "misfire" of sorts, but my mower will start working again if I leave it for 30 to 40 minutes, and I can't imagine a faulty hall sensor would reset and begin...

    I can't find that in the diagram. Is that the HALL sensor? I can't figure out what that part does, although someone else posted here that they had a bad hall sensor. the only heat sensor/cut off I could find in the parts diagram is on the charging port wire harness.

    Now that the drive motor controller has been replaced, it runs for about 30 minutes and then stops, yet everything else (lights, mowing deck, beeper, etc) works. I've done some testing and concluded it's an overheating issue. The reason I think this is because if I leave it sit for about 40...

    Update to my update. Was able to mow the front yard no problem then it started doing the same thing, only now I can't get it to reset at all. It's become a push mower. Won't ever make the mistake of buying a Ryobi again.

    Ryobi RM480E 38" riding mower won't move!

    Update:. I ordered the 996508001 DRIVE MOTOR CONTROLLER $275.41 This solved the problem and was very easy to replace. Again, my problem was that the mower would stop moving forward or reverse, but everything else on the mower would function. Power cycling off and on would reset it, allow...

    Ryobi RM480E 38" riding mower won't move!

    I am having the same problem. Everything else works, headlights light up, blades spin up, even get reverse beeping sound when I flip the direction switch to reverse, it just won't actually move forward or backwards. I found if I unplug the fuse that comes off the 12 v power converter (unit is...
