Abstract

A combine double-decker crop residue spreader for use with a rotating chopper having chopper blades and through which air is blown may include a divider panel separating a lower portion from an upper portion of the spreader. The divider panel extends rearwardly from a location where the chopper blades transition from rotating towards the divider panel to rotating away from the divider. An airflow conduit extends above the divider panel in the upper portion to rearwardly direct air flow. At least one lower vertical panel below the divider panel in the lower portion rearwardly directs crop residue.
