Does it grind when you try to put the pto in gear or will the handle simply not shift?
Your issue has nothing to do with the hydraulics.
On a Jube/NAA (and newer) the hydraulic system and clutch/pto are two totally unrelated systems.
In other words, you don't need hyds for the clutch/pto to work and you don't need clutch/pto for the hyds to work.
