ABSTRACT:
The disclosure is directed to a combine with a unique sealing arrangement between the pivotable feeder housing and the inlet opening. The rearward portion of the feeder housing, extending into the inlet opening, includes spaced apart arcuate smooth edge plates which mate with, but do not contact, sealing blocks affixed to the inside vertical side edges of the inlet opening. The feeder housing further includes axially aligned pivot arms which extend away therefrom to engage a pair of support yokes which permit the housing to pivot vertically. The pivot arms and the edge plates have the same central axis so that pivoting of the feeder housing does not interfere with the sealing block/edge plate relationship.
