Abstract
A chopper and wide-spread impeller spreader that feeds crop residue from the chopper into the spreader at a specific upward angle to more fully utilize the momentum the crop residue achieves in the chopper. The spreader incorporates air intake holes and air fins above the impellers to keep crop residue moving through the impellers without plugging of discharge material. The chopper propels the residue upwardly into the spreader resulting in a wide-spread broadcast, while preventing crop residue from plugging the spreader.
