A combine having a mobile frame and a harvesting header for removing crop material from the field and feeding it to a central location. A threshing and separating system separates grain from crop material and a feeder housing receives crop material from the harvesting head and conveys it to the threshing and separating system. A grain tank has a conveyor for transferring separated grain to the grain tank. Either of the harvesting header or the feeder housing has a perforated floor section sufficiently coarse to permit passage of grain to a conveyor beneath the perforated floor section that receives the grain and delivers it to either downstream of the threshing and separating system or the separated grain conveyor.
