Abstract
Abstract A harvester including a grain platform adapted to harvest corn comprising a plurality of ground-engaging divider points pivotally mounted and transversely spaced across the platform, for directing the stalks rearwardly toward the sickle. A vertically adjustable topping cutter is arranged to sever the stalks above the ear-bearing area and a deflector and a trash conveyor are provided for disposing of the severed stalk tops. A reel is located above the sickle and rearwardly of the topping cutter for influencing the ear bearing portion of the stalk that has been separated to fall upon the platform bed where it is collected and fed to the combine.
