When it comes to renewing agricultural machinery, the choice of the combine harvester is decisive for ensuring productivity and efficiency in the field. The main doubt among producers is between the axial and hybrid models, which present distinct threshing systems. The axial uses a single rotor responsible for threshing and separating the straw, being suitable for large volumes. The hybrid combines a conventional cylinder dedicated to threshing and two rotors for the final separation of the grains, uniting efficiency and a lower loss index.
