A crop residue spreader for an agricultural crop harvester such as a combine includes a rotor having a plurality of paddles including a first paddle having a first cross-sectional shape and a second paddle having a second cross-sectional shape, the second cross-sectional shape of the second paddle being different from the first cross-sectional shape of the first paddle. Different V-shapes can be used for the first and second cross-sectional shapes, the openings of the V-shapes facing in a forward rotational direction of the rotor. Multiple pairs of similarly shaped paddles can be used.
