Patent ID: 7426827

Claim:
A system connectable to a fluid drive source for providing pressurized fluid flow and configured to restrain oscillating movement associated with operation of a suspension arrangement for a boom assembly of an agricultural sprayer, the boom assembly pivotally supported by the suspension arrangement about a fore-and-aft axis independently of a carrier frame in support of the boom assembly from a wheeled frame assembly of the sprayer for travel in a forward direction, the sprayer including a fluid drive system configured to move the boom assembly between an extended position for operation in a field and a folded, non-operative position relative to the wheeled frame assembly, the system comprising: an accumulator; a cylinder actuator mechanically interconnected between the carrier frame and the boom assembly, the cylinder actuator in isolated fluid communication with the accumulator; a metered orifice connected in fluid communication to restrict a fluid flow between the accumulator and the cylinder actuator; and an actuator discharge valve configured to release a fluid supply from the accumulator in response to a loss of pressurized fluid flow from the fluid drive source; wherein the system automatically creates a force resisting rotation of the boom assembly about the suspension arrangement relative to the carrier frame.
