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.

Total Claims: 2
Claim 1
Independent Claim 200 words
A combine having a platform mounted thereon about a generally horizontal axis, said platform extending forwardly from the combine in the direction of travel; said platform including a transverse material table having a leading edge, a sickle mounted along the leading edge, transverse conveying means supported by said platform and overlying said material table for collecting crop material deposited on the material table; a plurality of elongated members pivotally supported at one end on said material table below said sickle about a generally transverse axis; ground-engaging shoes connected to the free end of said elongated members, divider points connected to said groundengaging shoes and extending rearwardly therefrom, said divider points terminating in free ends that overlie said sickle; an elongated topping knife, supported by said platform above and forward of said sickle, spanning said material table; a trash conveyor supported by said platform immediately behind and at the same elevation as said elongated topping knife, said trash conveyor being adopted to collect material, convey it in a transverse direction and deposit it along the cut crop side of the platform; and stalk depressor means, supported by said platform above said topping knife, for guiding the cut tops to fall forwardly.
