Patent ID: 8820429

Claim:
A fertilizer applicator comprising: a frame assembly having a carrier frame and a pair of outer wings pivotally coupled to opposite lateral ends of the carrier frame, the carrier frame adapted to be coupled to a towing vehicle and the outer wings each having an inner wing portion pivotably coupled to the carrier frame, an intermediate wing portion pivotably coupled to the inner wing portion and an outer wing portion pivotally coupled to the intermediate wing portion, and wherein the intermediate wing portion includes an intermediate wing frame member and the outer wing portion includes an outer wing frame member pivotally coupled to the intermediate wing frame member, and wherein each intermediate wing frame member includes an elongated hollow portion formed along a length of the intermediate wing frame member; an actuator assembly that includes a pair of actuators for folding/unfolding the outer wing frame members relative to the intermediate wing frame members, an actuator located in each one of the hollow portions of the intermediate wing frame members, wherein each actuator has a first end coupled to an intermediate wing frame member and a second end, opposite the first end, that is coupled to an outer wing frame member and wherein operation of each actuator causes an associated outer wing frame members to pivot about a pivot connection with an associated intermediate wing frame member; a plurality of ground engaging tools mounted to the frame assembly; and a pair of fold-up actuators for folding/unfolding the inner wing portions relative to the carrier frame.
