L3940 error code 81???

[Kelkie]

Hi, I have a L3940 HST no cab. It keeps throwing error code 81 not allowing the tractor to move forward or backwards with the foot pedal. It will rev the engine when you press the pedal but that's it. The only thing we've done so far is replace the potentiometer on the side of the pedal but that wasn't are problem, any help would be greatly appreciated thanks!

The manual for my 3560 says error code 81 is for the sensor for the speed control pedal. Is there anything there besides the potentiometer you found? It also says to contact dealer. I am curious to know if the code has to be cleared in the computer before it will work again even if you did replace the correct part? Sorry to not be of more help. Please post whatever you find out.

My suggestion would be to get the WSM for your tractor, and it will go through in detail how to troubleshoot and repair the issue.
