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.

A folding implement comprising, in combination: a center carriage having ground engaging wheels to support the carriage; at least one wing section cooperative with and hingedly attached to the carriage for pivoting the wing section between a field travel, extended position substantially transverse to the direction of carriage travel and a road travel, folded position substantially aligned with the direction of carriage travel; means for connecting the wing section to the carriage, said means for connecting having an upstanding wing support member and a first hinge connection defining an axis substantially aligned with the direction of carriage travel, said first hinge connection connecting the carriage to the wing support member and defining means for pivoting the wing section to follow the contour of the ground independent of the carriage when the wing section is in the extended position; said means for connecting further including a second hinge connection defining a substantially upright axis, said second hinge connection connecting the wing section to the wing support member and defining means for pivoting the wing section about the upright axis between the extended position and the folded position; and a flexible linking member connected between the wing support member and the carriage including means for altering the length of the linking member, said linking member controlling the extent of pivotal motion of the wing support member about an axis substantially aligned with the direction of carriage travel and further providing cantilever support for the wing section when the wing section is in the folded position.
