Abstract
A corn head includes plural pairs of first and second laterally spaced rotating stalk rolls each having outer fluting and plural outer arrays of spaced knife members extending along the length of each stalk roll. Corn stalks are directed by rotating pick-up cones each disposed forward of a respective stalk roll into the space between adjacent stalk rolls, where the stalks are directed downwardly through the inter-roll space and are reduced by the cutting action of the rotating knives. Each pick-up cone and its associated stalk roll rotate in opposite directions as do the two stalk rolls. Disposed above and extending along the length of the stalk rolls are a closely spaced upper auger and stripper plate which remove an ear of corn from the stalk and direct the ear to the combine for further processing. A skid plate is disposed adjacent a lower, forward portion of each pick-up cone.
