摘要:
A fertilizer applicator of increased operating width, e.g., sixty (60) or sixty-five (65) feet, has a carrier frame and a pair of wing sections pivotally mounted to opposite ends of the carrier frame. The wing sections include an inner wing member and an outer wing member. Each wing section includes an actuator for folding/unfolding a respective outer wing member relative to a respective inner wing member. The inner wing member includes a frame member defining an elongated cavity, and the actuator is positioned within the elongated cavity. This allows the actuator to effectively fold/unfold the outer wing member relative to the inner wing member without the physical structure of the actuator impeding movement of the outer wing member thereby allowing the outer wing member to pivot upland to a position against the inner wing member.
