Title: Seal for pivotable feeder housing

Abstract: The disclosure is directed to a combine with a unique sealing arrangement between the pivotable feeder housing and the inlet opening. The feeder housing includes axially aligned pivot arms which extend away therefrom to engage a pair of support yokes which permit the feeder housing to pivot vertically. The pivot arms include curved contact plates which sealingly engage at least partly semi-circular resilient closure members on the combine frame to prevent crop material from escaping between the feeder housing and the inlet opening.
