i see your point IG. widen the rotor, make it a little larger, lengthen the shoe along with width, put a bigger clean grain auger and elevator and bin loader, bigger unload auger, wider machine means bigger grain tank,and maybe bigger final drives, and crank that m-11 up above 400hp and you've got what sounds to me like a beast. i am a little scared of the sisu because it may not have enough meat for the horses.
