1. A harvesting header operable to harvest crop, said harvesting header comprising:
a header frame; a flexible cutterbar assembly mounted to the header frame to extend lengthwise in a lateral direction relative to the normal direction of travel of the header, said cutterbar assembly including a plurality of skids, each of which has a lower skid margin configured to engage the ground such that the skids cooperatively cause flexing of the cutterbar assembly along the length thereof in response to changes in terrain as the header is advanced, each of said skids presenting a skid surface comprising an aft portion that projects from the lower skid margin at a ground angle measured relative to the normal direction of travel, with the ground angle dimension ranging from about six degrees to about ten degrees, wherein said skid surface also comprises a forward portion that projects forwardly of the aft portion, said forward portion extending at a skid angle measured relative to the normal direction of travel, with the skid angle being different than the ground angle; and a draper assembly including an endless draper belt configured to receive severed crop materials from the cutterbar assembly and convey the materials laterally, wherein said draper belt comprises an upper run and a lower run below said upper run; and a lower run support assembly located below the lower run of the draper belt and at least partly over a portion of the plurality of skids, said lower run support assembly including a plurality of run support panels extending laterally along the lower run and a plurality of lower run support platforms supporting the plurality of run support panels, each run support platform being attached to a corresponding one of said plurality of skids, wherein said run support panels spaced from the plurality of skids on the run support platforms to define a residue opening therebetween through which any crop residue falling onto the plurality of skids is permitted to pass, the residue opening extending from an entrance adjacent a forward edge of the lower run and below the run support panels to a location adjacent the aft portion of said plurality of skids. |
