If the rest of the hydraulic circuits operate correctly the pump is not the problem.The power steering has priority over everything else so it gets the first oil by way of an orfice.The rest of the oil is bypassed through a flow divider valve which might be stuck open which will lower your steering pressure from 2200 PSI to about 250 PSI.Check also to see if the piston seal in the steering cylinder is leaking.Another problem that causes hard steering is a dry bushing just below the steering wheel on tilt steering tractors.However the biggest problem on those tractors is not hydraulic but worn and dry bushings and thrust bearings in the front spindles.If the hydraulic system is building pressure in the steering system you can hear the steering relief valve squeal when you turn the steering wheel all the way to the stop and hold it there.I hope that helps you.
