Abstract: Stalk rolls are used for a corn harvester having a body, an engine, a cab mounted to the body and a head mounted to a front of the body. The head includes an auger, row separators, corn stalk gathering assemblies between the row separators and ear removal devices. Each ear removal device includes a pair of stalk rolls. Each stalk roll has a core and longitudinally extending flutes spaced about a periphery of the core and extending along the core. Each stalk roll has a straight first section, a second section proximate a first end of the first section and having a first tapering profile, and a third section proximate the second section opposite the first section and having a second tapering profile.

Abstract: A foldable corn head having separable, matable auger sections which are cantilever suspended from the ends thereof to provide an obstruction-free path for harvested ears of corn being transported by the auger. Outer sections of the corn head are foldable vertically about horizontal hinges to reduce the width of the head for over-the-road travel. Stub auger sections are cantilever mounted from end plates in the pivotable outer corn head sections, at least one of the stub sections being driven by an actuator, such as a hydraulic motor means. The stub sections are provided with coupling elements at their inner ends which are matable with coupling elements in the ends of the main auger section. The elements have non-symmetrically disposed mating pins and bores to form the couplings and to align the ends of the helical auger flanges.
