Abstract: A harvesting machine having a guide mechanism adapted to direct a flow of crop residue from a threshing mechanism along one of three paths corresponding with three respective processing modes, the guide mechanism having a first deflection door and a second deflection door. An actuator and a first resilient element are coupled to the deflection doors, such that all three processing modes can be attained by contraction and extension of the actuator.

Abstract: A spreader for a harvesting machine includes a pair of counter-rotating spreader units each having an impeller and a fan supported on a common shaft. A plenum routes at least part of the airflow from a first fan to merge with chaff exiting the opposite impeller and at least a part of the airflow from the opposite fan to merge with chaff exiting the impeller on the machine side of the first fan. In one embodiment all airflow from a fan is ducted to an impeller on the opposite side, while a second embodiment commingles airflow from both fans in a plenum from which portions of the mixed airflows is directed to the chaff exiting each impeller exit. In a third, embodiment an established airflow receives chaff from the impeller on the side on which that airflow is generated.

Abstract: A spreader arrangement for an agricultural harvester includes a pair of spreader discs, at least one cover plate and a windrow chute. The spreader discs are generally horizontally arranged and rotatable in a counter rotating manner. Each cover plate is positioned at a location above a respective spreader disc, and is operable to inhibit a flow of crop material to the respective spreader disc when positioned above the respective spreader disc. The windrow chute has an entrance end positioned below the pair of cover plates and above the pair of spreader discs, whereby crop material is discharged from the top of the cover plates into the windrow chute.

Abstract: A crop residue spreader has a plurality of deflector elements arranged in a first group and a second group, a planar spreader frame element having a bottom surface to which the first and second group of deflector elements are displaceably mounted, the planar spreader frame element comprising a guide slot extending in a direction substantially perpendicular to the longitudinal axis, a first cover plate that is displaceably mounted to a top surface of the planar spreader frame element; a second cover plate that is displaceably mounted to the top surface of the planar spreader frame element and whereby a relative displacement of the first and second cover plates away from each other causes a part of the guide slot to be uncovered and a third cover plate is configured to cover, at least partly, the uncovered part of the guide slot.
