ABSTRACT:
A multisection farm implement includes a center carriage or center section and attached wing or outrigger sections. The wing sections are suspended from the carriage by means of a special hinge assembly which includes a first hinge couple for rotation about a horizontal axis so that the wing section may follow the contour of the field or be supported as a cantilever and a second hinge couple for rotation about a vertical axis so that the wing section may be folded between a field operating position and a road travel position.
