You must understand, and I will be perfectly clear, so that there isn't any confusion, the brand name "Cat" will not be prominently featured on any combine that is not manufactured by Claas (example, Cat lexion). The Massey "Challenger" combine is simply an axial configured rotor, based upon the WFE design (i.e., White 9700). The lexion 470 is a class 7 twin rotary separation combine.
