Abstract

A front attachment for a self-propelled combine harvester includes intake conveyor mechanisms arranged side by side having grooved conveyor wheels that rotate about a vertical rotational axis. Snapping units located downstream of the intake conveyor mechanisms in the direction of crop flow have snapping rollers extending horizontally and transversely to the direction of travel. A transverse conveyor is equipped with opposing auger sections drawn together in the center of the front attachment. The grooved conveyor wheels include extending driving elements that engage via sections thereof into guide channels to pick up and convey plant stalks in the direction of the center of the front attachment.
