Abstract: A harvesting system includes a header pivotally attached to a combine. The header includes a center section to which a left wing and right wing are pivotally attached. A suspension 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 flat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.

The sugarcane chopper further includes a leaf deflector attached to said main support. The shredder is connected to said leaf deflector on one side and a pneumatic impulse resource on a second side. The pneumatic impulse resource is further connected to a flow concentrator; and a discharge pipe connected to said flow concentrator. The chopper is configured so that biomass is directed by the leaf deflector to the pneumatic impulse resource and into the shredder, which in turn discharges the shredded biomass through the flow concentrator and the discharge.
