    TM155 Error Code F 64

    I don't have a book to check what this code means but it appeared once yesterday and today it appeared severals times.

    You would be driving along and next the tractor goes into neutral and F 64 flashes on the panel with the annoying alarm. Flicking the F/R lever sometimes gets her going but switching the tractor off and on can do the trick.

    Something is wrong so its won't be going anywhere till its sorted.

    Can someone please shed some light on this error code? Things go wrong when you really need the tractor.

    F 64 forward pressure switch faulty or open circuit or faulty sensor, presuming that it is a power command,not sure if it is the same on a range command.

    Its a power command.

    Bloody switches/sensors. I wonder if thats a simple fix and what's the odds, the switch costs a few hundred quid?

    Cheers for that. NH mechanic needed then.

    Does the tractor engage ALL the gears when driving? If it does then first thing to do is to check fuse 13.

    Every gear seems to work when the error isn't displayed.

    Will check the fuse this morning. If it is the fuse, what will cause it to blow?

    Thanks.

    Fuse could blow because of earth fault or componant fault.
    If the fuse is ok what gear does the tractor fail in? Always the same one? Will help to narrow down which pwm valve/part of the loom needs closer inspection.

    Fuse is fine. Error occurs in any gear. NH guy coming out in the morning to look at it.

    Cant be the fuse unless you fail to get moving again. Check for dampness in exposed areas switches etc ,as this could temporarily short the system but could well blow the fuse. Keep an eye out for a trend when it happens, gear, speed, terrain etc. Rough ground could be causing wires to move etc
