ABSTRACT:
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.
