My new to me 7580, when I am turning around with the disc it always steers fine the direction I turn it first but when I steer back to straight the steering wheel turns hard and the steering comes intermittent, with when the wheel gets hard to turn.  If i go slower turning the steering wheel then it doesn't do this, it makes no difference how fast ground speed is, how hard it is pulling, nor if the throttle is wide open or anywhere down to 1000rpm.  Wondering if there is a priority valve in the system....new filter and new fluid with about 50 hours on them.
What the heck is going on here, does the same when cold as when hot

Quite possibly one of the steering cylinders is leaking
