No Leak/Hydraulic Bypass?

    We have a NH 29hp loader/backhoe w/98 hrs. We noticed when we went back to the job where the tractor was left overnight, the stabilizers, the backhoe arm and the backhoe bucket had lowered 6-8 inches. We cannot find any leaks or oil residue anywhere. Is it possible that there is a check valve/diverter valve or a proportioning valve that is allowing a blow by? I do not have a service manual since I bought it w/68 hrs on it from a Kubota dealer. I would appreciate any help so that I am prepared before I call the NH dealer.
    Thank you.
