A mobile corn harvester comprises a chassis on which is mounted an upwardly and rearwardly inclined casing. The forward end of the casing is formed as a hopper into which fall corn stalks cut by cutters at the front of the casing. A rotor rotatable in the casing has a forward portion formed as a helical screw which separates ears from the stalks and transports the ears rearwardly to a thrashing section. The stalks pass down through an opening in the bottom of the casing and are crushed by lobed rollers. The thrashing section comprises a cylindrical screen and a rear portion of the rotor having thrashing loops and pins thereon. The grain kernels pass through the screen into a trough where they are transported to the rear of the casing and then up to a bagging platform. A radial fan at the rear end of the rotor draws off waste material and discharges it onto the field.
