In a self-propelled combine, crop material is gathered from a field and transferred by a chain and slat-type feeder house to a fore-and-aft disposed axial flow rotary separator including, from the front, infeed, threshing and separating portions respectively. The infeed portion of the rotor is in the form of a helical conveyor having an outside diameter of approximately equal to that of the threshing and separating portions of the rotor. The chain and slat conveyor of the feeder house, which is considerably wider than the outside diameter of the separator rotor, is arranged to deliver undershot fashion to he underside of the infeed rotor. An infeed or transistion housing surrounds the infeed rotor and the transfer point from the feeder house to the infeed rotor and includes a generally horizontal top wall above the infeed rotor, opposite upright side walls converging inwards from a point adjacent the discharge end of the feeder house to meet the cylindrical portion of the separator housing at about the beginning of the threshing section, and a forwardly and downwardly sloping floor approximately continuing the slope of the lower side or floor of the feeder house and meeting the cylindrical portion of the separator housing somewhat ahead of the threshing section. The walls of the transition housing cooperate with the feeder house conveyor and the infeed rotor to provide a smooth and efficient transfer of material from the feeder house conveyor through the infeed portion of the separator into the threshing section.
