  • Crop processing arrangement
    Patent number: 6036599
    Abstract: A crop processing arrangement (28) is proposed with a cylindrical rotor housing (42), an eccentric axle (44) rotatively supported in bearings therein and tines (46) rotatively supported in bearings on the eccentric axle (44). The transverse inclination of the tines can be varied by shifting the axial position of the eccentric axle relative to the cylindrical rotor housing. In this way a loosening and sideways movement of the crop conveyed by the tines (46) is attained with a relatively simple mechanism.
