ABSTRACT:
A header frame for a combine harvester having a linkage connection between the crop reel and the auger, whereby the auger may be automatically and mechanically raised from the header floor by raising the reel for purposes of unplugging wedged crop material. The linkage includes a lost-motion connection so that the reel can be moved vertically as required during harvesting without affecting the auger, and the auger is also capable of floating action during operation. A sprocket and chain drive for the auger includes a spring-biased idler sprocket for maintaining proper chain tension and uninterrupted operation of the auger at all times. An adjustable wedge is also provided for fixing and limiting the minimum spacing between the auger and the header floor.
