Abstract
A toolbar having a fixed center section and folding wing sections is mounted to and drawn by a tractor. The wings are each connected to the center section by a bi-fold hinge assembly which allows the wing either to fold upwardly for transport or to a forward position. The forward movement is automatically effected in response to the turning of the tractor to allow the toolbar to clear a drawbar-mounted drawn implement positioned aft of the toolbar. A lock pin is placed by the operator in one of two positions to determine the desired mode of operation.
