Power steering went out instantly,no oil going to steering motor.traced lines underneath tractor. Big metal line was warm coming from differential to thepump but line coming out is cold that goes up to steering motor. Any ideas.everything else works ,powershift and hydraulics..

What does it do? Spin free? Lock up? Or what?
First thing I would do is change left filter. MACK |

I drove it home you can turn it but really hard, my arms were numb by the time i got it home trying to turn on the intersections. Turned a plug out underneath on the pump.there was a spring and check valve. They seemed free.

When it happened the steering wheel locked up in my hand. After that happened i could turn it but really hard, no oil at all at the steering motor..

Is that a split pump underneath,because one line goes to the power shift filter in the rear

That sounds like left filter has collapsed or shrunk. My 7050 did that this spring and it was a Agco filter. MACK

I suppose rear end if full of oil. IT is possible it broke the gears in pump, I've saw it happen before but I hope not. MACK
