Before I messed around looking for problems under the top cover - ie lift piston, etc I would verify that you have good prime to the pump. That tractor came with a vane pump so yours has been retrofitted to a piston style at some point.
If the pump chatters and/or the lift arms stutter when you raise them that is usually a sign it's not not holding prime.
I would buy a pipe fitting with a hose barb and screw it into the test port on the side of the pump. Then hook a clear hose to it and run that back to the fill port on the rear end.
Start the engine and let it idle. You are looking for a steady stream of oil flowing through the hose. No bubbles or spurts.
Let it run for a while till you are getting a clear, bubble free, full flow of oil.
If it does not clear up I would pull the hyd manifold and replace the oring seals on both ends and see if that helps.
Having live hydraulics was a huge upgrade from the hydraulics the Ns had but they can be fussy and frustrating sometimes if they won't hold a prime.
