In this ancient, but fascinating thread:

BirdBob built a block to replace what looks like a cap with a passthrough from one port to another. This is where Kubota's add on remote valves go.
I believe what BirdBob did was to take the PB port, feed it to a regular all ports blocked/open center manifold and connect the output port of that manifold to (wha I think is) tank.
The existence of the third pipe (#110 in the drawing), suggests that Kubota's valves propagate the Power Beyond Circuit; I think that pipe goes to Tank. It's connected to what I've Labeled "B" in the photo of the rear block. It's currently plugged with a plastic cap.
I have such sandwich valve manifold and would like to do something similar to what Bird Bob did.
So, the general question is:
Can such a typical sandwich valve manifold (that passes oil from the inlet to the outlet through the manifold when all valves are at the center position), be used in a PB system, if it's last in line? That is, can the outlet be plumbed directly to Tank, if nothing else downstream needs oil? Does the PB port at the last thing in line on such systems go to tank?
The questions specific to the L5240 are:
Is the rear 3 pt hitch hydraulic block the last in line? Where does that pass through go? Tank? If so, what is the other port labeled "B"? They can't both be Tank. Finally, Anyone know what "C" is and where it goes?
Any guidance is most appreciated.
