Abstract
A knife bank assembly of a counter knife assembly of an integral chopper assembly of a combine harvester that includes an elongated bracket member that extends between opposed knife bank end plates and has a plurality of spaced retainment mounts securable therealong, with at least one, and preferably two, knife blades being removably connectable to each retainment mount in a side by side arrangement. The knife elements are removably connectable to the retainment mounts at first and second space mounting points, preferably in such a way that the knife elements are maintained in an extended position by application of a biasing force at the second mounting point but are rotatable about the first mounting point to a displaced or relaxed position if a sufficient force is applied to the leading edge of the knife element to overcome the biasing force.
