A mounting plate ( 16 ) pivotally supports a finger ( 14 ) for pivotal movement about a pivot axis A as a shear pin ( 34 ) breaks between a post ( 30 ) and the finger ( 14 ) in response to a predetermined force urging the finger ( 14 ) to pivot about the pivot axis A. A first fastener ( 24 ) is disposed under an opening ( 46 ) in the finger ( 14 ) for removing the mounting plate ( 16 ) and the finger ( 14 ) together as a unit from the transfer bar ( 12 ) while remaining connected by a bolt ( 36 ) at the pivot axis A.
