ABSTRACT:
A straw chopper is mounted at the rear hood of a combine harvester and includes a housing with a feed opening and a discharge opening and a rotor mounted in the housing comprising a hub with a plurality of blades mounted on the hub for chopping the fed materials and accelerating the chopped materials for discharge. A tailboard has a plurality of guide fins arranged relative to the housing so as to receive the chopped materials from the discharge opening to engage onto a guide surface and guide fins of the tailboard construction for spreading of the chopped materials to the sides. On each side of the tailboard an outermost one of the guide fins has a first fin portion extending downwardly from the bottom surface to an lowermost edge, a second fin portion inclined from the lowermost edge downwardly and toward the contact side of the fin and a third fin portion inclined from the second portion to the concave side and toward the bottom surface.
