Abstract
A connector assembly pivotally couples a caster assembly with a pivot arm of an agricultural implement. The connector assembly includes first and second structural support plates having openings to receive a connector pin therethrough pivotally coupling the arm between the plates. A fixed collar having a bore, and a lock pin passage aligned perpendicular thereto, is fixed at one of the first or second structural support plates to receive the connector pin therethrough. The connector pin includes a first end having an exterior threaded portion and a second end having a connector pin opening. The connector pin opening and the lock pin opening receive a lock pin therethrough that secures a position of the connector pin in the collar. Tightening a nut at the threaded end of the connector causes the structural support plates to squeeze against the arm, enhancing lateral support of the arm.
