On page 37, and 44 of the PDF, it shows the PB port. There are seven ports. If your tractor is closed center, you don't need the PB port. If it is open center, install the PB sleeve, and connect the other valves as directed. Tie all the returns together. Apparently the rear remotes gets the pressure first, and feeds the loader valve. They talk about back pressure through the loader valve presure return line. If you remove the loader, lines A and B must be connected to complete the circuit.
Line B will feel the full 2850 psi pressure when any other valve is operated, and the return port on that valve must be able to handle the pressure. I believe that most valves can not handle a back pressure of 2850 psi.
If the loader valve is attached to the rear remote, the PB is not used.
The hyd supply is at the back of the tractor according the PDF.
