ABSTRACT:
An apparatus for controlling the horizontal and vertical orientation of a boom assembly. An elongated frame assembly adapted to be mounted to a vehicle has a cam plate mounted to and moveable therealong. Hydraulic drive means controls the movement of the cam plate between fully extended, intermediate, and fully retracted positions. A hinge plate assembly is rotatably mounted to the frame assembly and an elongated boom, such as an agricultural spray boom, is pivotably mounted to the hinge plate so that the boom is vertically adjustable relative to the ground. The cam plate is adapted to engage the hinge plate and the boom in such a way that when the cam plate is moved along the frame assembly between the fully extended and intermediate positions, it adjusts the boom height relative to the ground and when the cam plate is moved between the intermediate and fully retracted positions, it causes the hinge plate to rotate about its pivot axis, thereby swinging the boom toward and into its retracted (traveling) position.
