    Default New Holland TN85A Power Shuttle Problem

    I have a TN85A that will go into forward and reverse using just the power shuttle but will not engage when using the clutch. The power fault code that is showing up is 47. Any ideas how to fix this?

    The clutch pedal switch position is too high as related to the signal the ECU is recieving from the clutch pedal potentiometer. A fairly common maladjustment, but I have to say I have never had a case where THAT fault disabled the clutch pedal entirely. You will have to have a CDU (diagnostic tool) or a laptop with EST software installed (also a dealer only item) to read the numerical values from the pot and set the switch in the proper position (at the very least). It is likely that there is something else going on there as well.

    If you depress the clutch pedal while moving, does the tractor stop?
    Spring is the season of optimism.
