S P E C I F I C A T I O N HEADER SUSPENSION AND LIFT MEANS ABSTRACT OF THE DISCLOSURE A crop harvesting machine has a crop harvesting header, a mobile frame and improved header suspension and lift means. The frame is adapted to move across a field in a forward direction and includes upper frame structureextending transversely to the forward direction and a lower wheel frame assembly. The assembly includes a transverse cylindrical member being rotatably mounted to and supporting the upper frame structure. Lift means is provided, being actuatable for moving the lower assembly, and thereby rotating the cylindrical member thereof, relative to the upper frame structure to effectuate raising of the upper frame structure and the cylindrical member relative to the field. The improved header suspension and lift means includes upper means pivotally interconnecting an upper portion of the header with the upper frame structure and lower elongated means pivotally interconnecting a lower portion of the header with the cylindrical member of the wheel frame assembly. The lower means has a portion which projects rearwardly of the pivotal connection of the lower means with the cylindrical member and underlies the member so as to be engaged by the latter to effect lifting of the header upwardly by the lower means upon rotation of the cylindrical member when the lift means is actuated so as to effectuate raising of the upper frame structure and the cylindrical member relative to the field.
