I have a Bobcat 751 that is giving me problems I can't seem to resolve. When I push pedal for raising the bucket it will come up as it should but there is a particular spot it will just drop. If I press pedal down or up more and get away from this spot in the travel it will go up like it should. I have no idea what to do and am hoping to get some help here. Any assistance would be greatly appreciated. Thanks in Advance!
