Good job!
And then on the John Deere 8x20 series, the return pressure from the OC orbitol valve gets regulated to ~300 PSI and feeds the diff-lock solenoid, PTO solenoid, and the power shift solenoids. The brake cylinder has a load sense coupled to the orbitol valve that if the oil pressure drops out, the brake receives all oil, and the steering and the rest of the system receives nothing.
