Claim:
1. A crop residue management apparatus for flexible distribution of straw and chaff contained within the crop residue, said apparatus comprising: a pair of laterally spaced spreader devices for distributing a crop residue laterally; a duct, including a swath door having a pivotable connector such that the swath door is displaceable between a lower position in which the crop residue stream is directed to the spreader devices in a downward direction and an upper position in which straw is permitted to bypass the spreader devices; a windrow chute displaceable between a first position in which the windrow chute is out of the crop residue stream and a second lowered position in which it directs straw in the residue stream over an upper surface of the windrow chute in a windrow behind the apparatus and directs chaff laterally; and a linkage interconnecting the swath door with the windrow chute so that the movement of the swath door to its lower position raises the windrow chute out of the crop stream and displacement of the swath door to its upper position lowers the windrow chute to a position below the swath door and within the crop stream, the linkage comprising a pivoting bar assembly, wherein the windrow chute is mounted from a first portion of the bar assembly and a second portion of the bar assembly is movably coupled to the swath door below the pivotable connector of the swath door.
