7745 No Hydraulics

The old Zetor 7745 been working like a mule for several years now. Went out to load hay and no movement in the front or rear hydraulics. Made sure pto/hydraulic lever all the way forward and still nothing. Also have no PTO in the second position. Took off inspection plate on bottom and looks to be intact. Pulled pump and tested good. What could I be missing....

Sounds like either the little pin has sheared off or the pto lever linkage is breaking the weld on the inside of the gearbox cover. You should have 4 positions on it. Right forward is Hyds, No.2 is hyds and pto, No.3 is neutral, right back is Pto only (no hyds).
