When I am using my auxiliary hydraulics, to make it lift a hay bine or similar piece of equipment I have to turn my steering wheel to full left or right and dead head it and it makes lift fine, if I don't it does not have any pressure. Lift arms work fine anytime. Any suggestions? Filter and oil have all been changed.

It sounds to me like you have a stuck flow divider valve spool or the orfice has turned in it"s bore or fallen out. The orfice is in the flow diver valve where the large hose coming up from hydraulic pump enters the valve. The hitch has a separate pump that is why hitch works. I think there is a serial number break as to exact style of hydraulics you have but from your description of problem I think this is your type. I have made a few orfice"s for the 656 with same valve by cutting off a piece of round stock (think bolt)but can"t remember exact size of orfice hole.
