We pioneered rotor development back in the 1960s. Since then, refinements, enhancements, and improvements have led to the pinnacle in rotor performance, the AFX rotor. It features constant pitch impellers that draw the crop and air into the rotor. The AFX rotor can be set into many configurations, adapting to both crop and threshing conditions with the use of straight bars, spiked rasp bars, and helical kickers. Competitive rotor and cage designs can reduce productivity, and increase grain damage because of inefficient feeding and crop-control designs.
