I have a pre Husco hydraulic system. Everything worked ok when parked 6 months ago. after starting, the hydraulics has very little pressure. When the 3 point lever is moved, the 3 point arms will creep up but I can push them back down by hand. Acts like there is a huge internal oil leak. When the level is released, the 3 point arms will lock and stay in place.The remotes also have very little pressure. Oil will shoot out if remote line is opened and lever moved..
I have removed cover # 41 in link and inspected the spool. Everything looks ok.

Hydraulic Implement System -> ?80-3/4-222-3? Hydraulic Control Valve

Any other idea? Can a pump go bad just setting there? Maybe some ice formed in the pump during this cold winter and broke something?
I have 2 repair manuals but they don't go into hydraulic trouble shooting or explain the oil flow. Is there a detailed hydraulic manual?
