Abstract
In a forage harvester, a pan-like shield wraps the underside of the lower forward feed roll of a feed roll assembly having opposed upper and lower pairs of feed rolls. The pan is disposed so that particles of material, such as corn or sorghum kernels, which may become separated from a mat of material being fed through the rolls and pass downwards in front of the forward lower feed roll or between the front and rear lower rolls are intercepted by the pan and recirculated by the forward roll between the roll and the pan and re-presented to the inlet side of the feed roll assembly so that those particles have another opportunity to be fed through with the mat of crop material to the cutterhead.
