Abstract
A self-propelled farm implement has independent front and rear, wheel supported frames articulated therebetween for execution of turns by operator steering of the front frame from within a cab that is, in turn, mounted on the front frame. The rear frame carries a crop receiving bin which, except for my oscillator limit incorporated in the combination, would be engaged by the cab under certain unlevel ground conditions, causing substantial damage. The front frame is tiltable about a fore and aft axis within a range defined by interengageable stops between the front frame and its coupling link. The stops on the front link are in the form of pivoted members which abut lugs on the rear frame causing the members to swing about their pivots during turning movements. The effect is to progressively limit the extent of tilt as full turns are approached to prevent cab-bin interengagement regardless of the nature of ground contour as the vehicle is steered off a straight path of travel. In the event, intermediate the turning movements, the front frame has reached its maximum tilt, further turning is precluded which also prevents damage to equipment carried by the frames.
