摘要： An axial flow combine harvester is disclosed wherein the threshing rotors are provided with segmented rasp bars staggered around the circumference of the rotors and spiralled with respect to the axis of rotation of the rotors. Each rasp bar segment is circumferentially offset approximately 60 degrees relative to each other to spread the threshing forces around the circumference of the threshing rotor, minimizing variations in threshing forces and increasing the life of related components.
