Abstract
A farm implement of the sectional tow type having at least two rigid frames positioned end-to-end and pivotally interconnected, includes a restrictor apparatus for resisting excessive oscillation between the frames and comprises a fixed and a reciprocating bracket having cooperating faces which are urged abuttingly together by a resilient member. The fixed bracket is attached to and disposed upstanding from one of the frames adjacent to the end thereof, and the reciprocating bracket is connected to the other frame by a linkage mechanism having one end pivotally attached to the reciprocating bracket in a spaced relation to the face thereof and having the other end pivotally attached to the other frame in a spaced relation to the pivotal connection. The resilient member is further compressed from a precompressed condition upon pivotal frame motion by the articulate movement of the reciprocating bracket relative to the fixed bracket. The restrictor thereby permits swinging motion between the frames during an operational implement position for conforming the same to the contour of the underlying terrain, and prevents undesirable oscillation between the frames during a transportational implement position.
