Abstract
The combine harvester (10) has a bar (94) with male ends (96) and (98) attached to the elevator housing (20). The male end (96) has an arcuate surface (100) and the male end (98) has an arcuate surface (102). A left female arcuate section (158) and a right female arcuate section (160) are secured to the header frame (64). An arcuate plate (168) of the arcuate section (160) engages the arcuate surface (100) and an arcuate plate 182 of the arcuate section 160 engages the arcuate surface 102. A hook assembly (110) in the lateral center of the elevator inlet (47) and below the floor (24) of the elevator housing engages the round bar (154) and clamps the header (62) to the elevator housing (20). A hydraulic cylinder (196) is connected to the elevator housing (20) and the header (62) and pivots the header relative to the elevator housing about a generally horizontal fore and aft axis adjacent to the hook assembly (110).
