A harvesting header includes a header frame, a flexible cutterbar assembly, and a draper assembly. The cutterbar assembly is mounted to the header frame and includes a plurality of skids. The draper assembly includes a draper belt with upper and lower runs, and a run support panel is provided below the lower run. The run support panel is spaced from the skids to define a residue opening therebetween through which any crop residue falling onto the skids is permitted to pass.

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 configured to engage the ground and thereby cause flexing of the cutterbar assembly along the length thereof in response to changes in terrain as the header is advanced; anda draper assembly including an endless flexible draper belt configured to receive severed crop materials from the cutterbar assembly and convey the materials laterally,said draper belt presenting laterally endmost margins, with upper and lower runs extending between the margins; anda lower run support assembly located below the lower run of the draper belt and at least partly over the skids,said lower run support assembly including a run support panel extending laterally along the lower run,said run support panel being spaced from the skids to define a residue opening therebetween through which any crop residue falling onto the skids is permitted to pass,said residue opening being defined under the run support panel so that crop residue passes underneath the run support panel and above the skids. 2. The harvesting header as claimed in claim 1, said draper belt being supported on the header frame to flex with the cutterbar assembly as changes in terrain are encountered. 3. The harvesting header as claimed in claim 2; and a plurality of laterally spaced apart pivotable support arms being attached to and cooperatively supporting the flexible cutterbar assembly,each of said support arms being pivotally coupled to the frame for swinging movement about a laterally extending axis,said draper belt being carried on multiple ones of the support arms so as to flex with the cutterbar assembly. 4. The harvesting header as claimed in claim 1, said lower run support assembly being attached to and supported by at least one of the skids. 5. The harvesting header as claimed in claim 4, said lower run support assembly including a plurality of upright legs spaced along the lower run,said legs interconnecting the run support panel and the at least one skid. 6. The harvesting header as claimed in claim 5, said legs sloping upwardly and rearwardly from the at least one skid. 7. The harvesting header as claimed in claim 4, said residue opening having a minimum cross-sectional dimension measured between the run support panel and the at least one skid,said minimum cross-sectional dimension being about two inches. 8. The harvesting header as claimed in claim 7, said skids having a forwardmost edge,said cutterbar assembly including a sickle assembly mounted to the skids adjacent the forwardmost edge,said run support panel presenting a forward margin,said forward margin being spaced rearwardly about five inches from the forwardmost edge. 9. The harvesting header as claimed in claim 8, said draper belt presenting laterally extending, spaced apart leading and trailing edges relative to the normal direction of header travel,said leading edge of the belt being spaced forward of the forward margin of the run support panel. 10. The harvesting header as claimed in claim 4, said skids each presenting a cutterbar-supporting forward section and a ground-engaging aft section,said run support panel being positioned substantially entirely above the ground-engaging aft section. 11. The harvesting header as claimed in claim 10, said lower run support assembly including a platform that is attached to the aft section of the at least one skid and supports the run support panel. 12. The harvesting header as claimed in claim 11, said platform presenting upper and lower ends, with the lower end being attached to the aft section of the at least one skid and the upper end being attached to the run support panel,said platform projecting upwardly and rearwardly from the lower end toward the upper end so that the run support panel is spaced upwardly and rearwardly relative to the at least one skid. 13. The harvesting header as claimed in claim 1, said draper belt presenting laterally extending, spaced apart leading and trailing edges relative to the normal direction of header travel,said run support panel being spaced entirely rearwardly from the leading edge of the draper belt. 14. The harvesting header as claimed in claim 13, a plurality of belt guards attached to and disposed along the cutterbar assembly to accommodate and move with the cutterbar assembly during flexing thereof, with each of the guards extending from the cutterbar assembly to a location adjacent the leading edge of the draper belt,said run support panel being spaced entirely rearwardly from the belt guards. 15. The harvesting header as claimed in claim 1, said skids each presenting a cutterbar-supporting forward section and a ground-engaging aft section,said skids each including a fore-and-aft rib extending between the forward and aft sections to restrict relative flexing between the forward and aft sections. 16. The harvesting header as claimed in claim 1; and a plurality of laterally spaced apart pivotable support arms being attached to and cooperatively supporting the flexible cutterbar assembly,each of said support arms being pivotally coupled to the frame for swinging movement about a laterally extending axis,said skids each including a mounting bracket,said mounting bracket being attached to a respective one of the support arms so as to be swingable with the one support arm about the laterally extending axis. 17. The harvesting header as claimed in claim 16, said mounting bracket being pivotally attached to the one support arm to pivot relative thereto about a fore-and-aft axis. 18. The harvesting header as claimed in claim 16, said skids each presenting a cutterbar-supporting forward section and a ground-engaging aft section,said skids each including a fore-and-aft rib extending between the forward and aft sections to restrict relative flexing between the forward and aft sections. 19. The harvesting header as claimed in claim 18, said mounting bracket and said rib being interconnected to cooperatively provide skid reinforcement structure that restricts relative pivotal movement between the forward and aft sections. 20. The harvesting header as claimed in claim 1, said run support panel presenting a forward margin that is spaced entirely from the skids so as to define an entrance to the residue opening.
