Vassalli revolutionized the market with the DR550 hybrid model whose main innovation is the dual threshing system that combines a conventional transverse threshing cylinder with two axial separating rotors. Simple, robust and efficient.
Hybrid, dual or mixed threshing systems have been gaining ground in different countries arround the world due to their high harvesting efficiency, especially in the segment of equipment up to 280 HP. Dual threshing proposes a low aggressive transverse cylinder, which is complemented by high productivity axial separator rotors to achieve high overall efficiency in the process, with high threshing quality and low consumption.
