This might be an easy fix. Under the right lift arm on the 3-point hitch is the PTO valve. On the side of the PTO valve is a tee fitting with a hose connected on the front and a JIC cap plug on the rear. Make yourself a 3000 psi gauge to connect to where this cap plug is. With the engine running you should have 500-600 psi and when you pull back on a remote lever you should get 2500 psi. You probably have zero psi. Swing out the battery tray and locate the compensator control valve on the front of the main hydraulic pump. Check the small spring and shims first. I think you have something wrong there.

This is a pdf file but this site states it is not a pdf file - so it will not open - grrrr
Item 54-55 are the shims and 56 is the spring to look for

So, you need some new shims because your pressure isn't in that 500-600 psi range.
