Abstract

A crop residue harvesting system for a harvesting machine is provided. The crop residue harvesting system includes a blower and a transition member having a first position and a second position. In a first position the transition member directs at least a portion of the crop residue to the blower for harvesting of the crop residue. In a second position the transition member allows for spreading at least a portion of the crop residue. A lever or actuator may be operatively connected to the transition member for selecting between the first position and the second position or selecting an intermediate position to control the proportions of the crop residue harvested and the crop residue spread.
