    Blade drops on unit when traveling and will not hold in down position.
    Seems to be worse with Right track movement?
    Any suggestions where to start?

    Exactly dead center of the machine, it passes oil to and from the lower frame implements, and allows the top (house) to rotate infinitely upon the lower frame.

    The best we can do its not your exact model but it may well help you make a plan.
