Abstract

See full text

A harvesting system includes a header pivotably attached to a combine. The header includes a center section to which a left wing and right wing are pivotably attached. A wing locking system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially fiat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.
