I am working on one of these tractors for one of my customers. It came from the factory equipped with Beeline steering. I am trying to figure out if I can steer the factory valve with a SteerCommand Z2.  The WAS can either be reused or easily be replaced, the valve is Danfoss and I have the pinouts and should be able to drive it. The only question I have is how they handled manual steering override. The steering valve is built into the steering hand pump. I did not see a pressure switch or sensor on the unit, but being it is crammed up on the firewall I cold have missed it. I did not disassemble the steering column to look for an encoder either. Does anyone know how Beeline set up the manual override on these tractors? I'm striking out digging through AGCO parts books as well. Thanks.
