Abstract
In a combine harvester comprising a separating device which operates by the axial flow method, a chopping device which operates by the axial flow method designed in such a way that the components of the separating rotor's chopping device can be replaced in a very simple manner and are kept to a minimum. In the combine harvester according to the invention, the impact teeth, arranged in a spirally or helically extending row, form a one-piece impact tooth functional part which can be replaced as one single piece. One-piece filler bodies located between the individual rows of impact teeth are provided with cutting channels which are entered by the chopper blades on rotation of the rotor. The impact teeth are also provided with cutting grooves to reduce the length of the chopped material. The combine harvester is particularly designed for harvesting cereal.
