Hi guys, I'm new to the forum and wondering if anybody has had this problem. A few months ago our L4240 HST threw a error 91 code and we lost reverse in our tractor but it would go forward. After looking at the service manual, we checked all wires from the traction pedal to the ecu and everything checked out. We then replaced both proportional values underneath the pedal. That seemed to fix the problem until last week where the error 91 came up again. We have been on the phone with our kubota dealer and they haven't been much help as they have never heard of this problem.

Just curious if anybody has any ideas before we send the tractor to kubota to have them try and solve the problem.

Thank you.
