I have a John Deere 790 with the rear hydraulic remote. For those not familiar with this setup, JD takes the power beyond tap (normally goes to rock shaft) off the SCV and creates a loop to the rear of the tractor with a hose and quick disconnect. If you are not using the rear remote, you must have the hose connected in the quick disconnect to complete the loop to the rock shaft and back to the tranny. They tell you not to operate with the loop not connected or through an open center valve. My question is - does the valve need to be just open center or must it have power beyond. I have asked locally and no one seems to know, even JD dealer. From what I see, the power beyond is not needed if I do not want to operate the remote and rock shaft at the same time. Also, there is not a provision for a return line to the transmission is the JD setup, thus having the open center return to the transmission (as with the SCV) means some fancy plumbing. I do know that if I have the open center return to the transmission instead of the rock shaft, I definitely need power beyond.
Thanks for any input.
