This post is in reply to Posted case on March 1, 2008, regarding Case 644. I have a 646, it has the same problem. Yes, there is a complicated forward and reverse travel linkage that a shifting pin, if you will, slides in a half moon slot. The problem is the shifting pin will bend and the slot will wear out and the cross linkage will wear enough to prevent full pressure to the travel spool. Both forward and reverse. Take the linkage apart and weld it up and clean it up with a die grinder and a round file. Replace the shifting pin with a case hardend bolt. Replace bushings and all worn parts. Make all other adjustments, springs etc. and you should be good to go. One other thing, these case tractors do not operate on hydraulic fluid. They take Shell Rotella heavy duty tractor fluid.
