Well if your PTO is quitting when you go up hill your losing charge pressure. By not fixing it when it first started doing it you more than likely have problems in the main pump now. The trouble is the main hydraulic pump is striving for hydraulic oil. The shutter your hearing is the main pump chattering from lack of oil on the suction side. The start was just at idle now as it is worse it is all of the time. The PTO hydraulic clutch is ran off of charge pump pressure. So if the PTO lines/hydraulic lines are broken/cracked then your losing charge pressure. It could be the orings in the control valve but it is not likely as the lines are a known failure area. The shutter/chattering will ruin the valves on the back of the pistons in the main hydraulic pump.
To really know you need to check the charge pump pressure. I don't remember what the pressure should be exactly. IRC it is around 150-175 PSI. Guys down on the JD board would remember the exact number. I have not been inside a Mannheim designed tractor in years. They can be a PAIN to fix the hydraulics on. Especially if they are ran with issues. The troubles can spread through the entire system.
The first issue is more than likely the internal hydraulic lines inside the front of the transmission housing. This would be right under the gear shifters. It requires a split at the back of the clutch housing. You can check them by removing the gear shifter housing from the top if the transmission.
You will need to find a mechanic that is familiar with the pre 6000 series Mannheim tractor hydraulics. That is getting harder to do as the older guys retire. Not many younger fellows will have the knowledge to do the repairs in a timely fashion. These tractors can be hard to fix the first, or even the second time. The system is not technically complicated but they always seemed to be more delicate than the Waterloo system. An example of this would be brake linings failure on these tractors would send metal through the entire system. I do mean the entire system, steering valve to the SCV valve, and three point. How it gets by the filters I never could figure out.
So QUIT USING IT!!!!! RIGHT NOW!!!! The longer you run it the more your going to spend to fix it. I hope your PTO clutch is not smoked now. You have been running it with low pressure so it can slip under load easily.
Also your manual is the fix and repair one if it does not have the test in it. You need the other manual: 2155 to 3255 Tractors Operation and Test TM4436S $50
