Abstract
An axial flow combine harvester comprises a rotor having a separator section which can be adapted to suit different crops. Within the separator section staggered crop engaging elements are spaced from one another along a first helical crop flow path. The crop flow path can be modified to suit crops such as corn and sunflowers by attaching at least one separator blade to the rotor in place of or in addition to selected crop engaging elements of the rotor. The separator blade forms a continuous crop engaging surface defining a second helical crop flow path of greater pitch than the first path defined by the staggered strop engaging elements.
