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.

A separator arrangement has an inlet head housing, a feed drum and two axial separating rotors projecting by one end portionwise into the inlet head housing. The inlet head housing has planar inlet portions which extend over the width of the respective axial separating rotor and between which is arranged a ramp-shaped housing portion extending paraxial to the conveying direction of the axial separating rotors and which assists in dividing a harvested material flow into partial flows to be fed to the axial separating rotors. At least one separating element is associated with the ramp-shaped housing portion and has a base body which extends perpendicular to the surface of the housing portion and which has an end face formed as a cutting edge. A coating comprising a wear-resistant second material is arranged on the end face and extends substantially medially in the longitudinal direction of the end face.

A spreader of a combine for conveying crop residue rearwardly from a rotor assembly includes a frame coupled to the combine and has a top portion adapted to receive a portion of crop residue during a harvesting operation. An impellor includes one or more blades for rotatably conveying crop residue rearwardly, and an actuator is controllably moved between an extended position and a retracted position. The actuator is pivotally coupled to the combine. A linkage assembly is pivotally coupled to the actuator at one end and to the frame at another end. The spreader is disposable in a first position when the actuator is in the extended position, and the spreader is disposable in a second position when the actuator is in the retracted position. A movement from the extended position to the retracted position induces pivotal movement of the spreader from the first position to the second position.

A separating rotor with a rotor tube for use on a combine harvester has a plurality of crop engaging finger elements. Each finger element is mounted to a respective finger support which is secured to the rotor tube. Each finger element has a planar body with a flared base portion which presents a leading edge to the crop material with a relatively shallow angle with respect to the tube.
