Have you try tighten all hyd. fittings..air leak.

Most common cause is a quick disconnect that isn't fully seated. Uncouple and reconnect all of them to be sure they are fully seated.
Bet that will cure it.

Take the pressure line off where it goes into the valve or into te tractors transmission usually theres a 3 bolt flat fitting. See if its getting any flow. If not and the pump isnt squalling like it starving. I went through this on my YM3000. What happened on mine water got in the transmission from a leaky shifter boot. One night it was 14 and I started the tractor. THe lift didnt work after that. What happened the pump shaft snapped off. I figured the pump had frozen and when I started it just snapped. I had to buy a replacement at Hoyetractor for 400.

Does the powersteering still work if its euipped. Im not familiar with your tractor. Also the suction screen could be plugged.
