Patent ID: 7581597

Claim:
A method of moving an agricultural implement between a folded, inoperative system for transport and an extended, field position, the method comprising the steps of: providing an agricultural implement having a right wing of tools and a left wing of tools each located on opposite sides of a central longitudinal axis of the implement relative to each other; connecting a right wing actuator to the right wing of tools and a left wing actuator to the left wing of tools; interconnecting the right and left wing actuators to a fluid drive source with a valve assembly, the valve assembly including a first valve and a second valve each in fluid communication with both the right and left wing actuators, each first and second valve including a selector configured to communicate a fluid flow from a single inlet port to one of a first outlet port in fluid communication with left wing actuator and a second outlet port in communication with the right wing actuator, the selector of the first valve mechanically connected to move with the selector of the second valve; moving one of the right and left wings of tools from an extended position to a folded, inoperative position for transport in response to the configurations of the selectors of the first and second valves; and moving the other of the right and left wings of tools from an extended position to the folded, inoperative position for transport after executing the step of moving one of the right and left wings to the folded, inoperative position in response to the configurations of the selectors of the first and second valves.
