ABSTRACT:
An impeller-type cutter drum for a chopper has a drum body including three drum disks arranged side-by-side and supporting two rows of blade holders which are spaced about the circumference of the drum body. Each blade holder supports a chopping blade and extends between a respective one of the outer disks and the center disk upwardly in an upwardly inclined and oblique manner. The front portion of each blade holder is shaped as an impeller which is arranged at constant distance to and has corresponding inclination as the chopping blade. Each impeller has an arc-shaped deflector portion immediately adjacent the centered drum and extends in a plane approximately adapted to the plane of the drum shaft which support the disks.
