further clarification on that pin-- the control valve spool is two pieces- the bottom half is inside, not visible. if you look on the bottom of the pto housing directly below the control valve, there is a hex headed plug. if you remove that and the bottom half of the valve stem falls out, that's your problem (hyd oil will leak but not too fast, just put the plug back right away and you'll only have to catch a couple cups).
to repair- parts of the hitch have to be removed for clearance, but unscrew the nut from the top of the valve stem and the whole works comes out the bottom. replace the pin and put it back.
a common cause of the pin breaking is if the over-center linkage is worn, then when you push the lever to "off" it allows the spool to drop all the way and shear the pin. if you can gently move the lever over center but "catch" the valve partway, then ease it to the "home" position, that will help to not break the pin.
