How you plumb the plow cylinder(s) depends on what you have. Your original post indicated you have some sort of truck plow and I was assuming it already had hydraulic angle on it. This sounds like you are adding it. OEM setups commonly pair two single acting cylinders in opposed positions and use one to angle the blade while retracting the other. Additionally a cushion valve is mounted in the middle of the circuit to protect against damaging the plow and/or plow truck by hitting obstacles. The cushion valve allows the impacted cylinder to retract and the other to extend on extremely hard impacts rather than hold the blade hydraulically locked in a fixed position. I.E - it cushions the impact to prevent damage.
