B7500 HST power steering and and 3 point lift problems in high temp.

   / B7500 HST power steering and and 3 point lift problems in high temp. #51  
I have a B2400HSD. My tractor does not appear to be plumbed as shown with the return line going directly into the main line. I could be mistaken but this does not seem to apply to my problem. Again, since I've been using AMSOIL hydraulic fluid, with the exception of the first 2 or 3 mowing jobs, I've had zero problems. In the past I used UDT, Super UDT, Bobcat fluid, and TSC fluid. When I was using any of those fluids, after an hour of hard mowing, I would completely lose the power steering when I made any left turn. Thank heavens for the AMSOIL.

You can try and raise your system relief pressure. or it also sound like a gear to housing issue with your pump (worn out) but if it only happens to a left hand it almost sound like a steering valve problem. probably should start with checking your system relief pressure.
