ABSTRACT:
A crop residue handling device is mounted to the rear of a combine harvester for intercepting crop residue that remains after grain has been separated from the crop by the separator and cleaning arrangement of the harvester. The residue handling device includes a chopper which chops and impels the chopped residue rearwardly through a discharge duct. A transition duct receives the crop exiting from the chopper and contains upright deflector vanes mounted for pivoting and being automatically moved among desired positions, by a power actuator so as to direct desired proportions of the crop residue between a blower for receiving and accelerating the crop through a discharge chute for collection in a receptacle of a towed trailer, and a pair of spreader disks located at opposite sides of the blower for receiving and dispersing the crop residue on the ground.
