A residue handling system of an agricultural harvester includes a straw beater for receiving material other than grain from a threshing and separating system. A subsequent residue treatment device receives the material from the straw beater and breaks down larger parts of the material prior to discharge from the agricultural harvester. At least one wind generating system is located at an end of the straw beater and directs a flow of air from the vicinity of the straw beater to the subsequent residue treatment device. The flow of air is directed to pass substantially through an upper rearward part of the residue handling system. The flow of air operates to further entrain, render airborne, and transport material other than grain proceeding from the straw beater to the subsequent residue treatment device.

Fan in beater to avoid strawhood blockages

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.
