The hitch has separate pump, and the flow from it joins aux valve when hitch is not moving up. You could flow rate the aux valves and determine if main pump is delivering flow or not or just worn out. You do that by moving hitch position control lever past normal stop until it stays on demand so all flow from hitch pump is directed to hitch and it will go over hitch relief valve which is separate from main relief valve. First thing I would do though if you do not have a flow rater available is take off the large hose from main pump to steering valve and look inside at the orfice. It is merely a pressed in disc and sometimes turns sideways or falls out or even disentegrates which will then cause all flow to go to steering. Surprisingly enough, you may not notice any difference is steering action but may hear more whining from it. I am going with a gear drive tractor here not hydrostatic drive.
