are you running it on a tractor that has a gear pump "open center"
power beyond would be running off a supply from beside your tractor valve stack wth a return going back to the supply from the 4 valve stack in your cab
Power beyond can be on a open or closed tractor
just means that the 4 valve stack is a open or closed stack
