Abstract
A mechanical overload member apparatus for use with a planter apparatus including a coulter bar and coulter/fertilizer units mounted thereto, the coulter bar pivotally mounted to the underside of a wheel supported carrier frame designed for transport in a transport direction where a hydraulic cylinder is linked between the frame and the bar for moving the bar between a ground clearing transport position and a ground engaging position where the frame, cylinder and frame form a linkage path, the overload member linked within the linkage path such that a draft force applied to the bar in a direction opposite the transport direction causes a secondary force on the member and, when the secondary force exceeds a threshold force, the overload member failing and thereby rendering the linkage path non-rigid.
