hello what started as a simple clutch replacement, might have roots as a different problem.I split the tractor(1987 7745 US MODEL) took the clutch pack out and the pto clutch plate is the one that is warn down to rivets and the drive plate still has some life left in it. The tractor itself just acted like the clutch was warn and would slip more as it got hotter or under any type of load. Could it have been adjusted wrong,bad hydraulic cylinder,or there was a rod disconnected above hydraulic cylinder that was unhooked when i purchased it ,which i would need to find out where it hooks to. The new clutch plates are ordered and any ideas would be useful. thanks
