Abstract

A sieve lining for a concave in a threshing mechanism of a harvesting machine accommodates larger threshing cylinders while still allowing the sieve lining segments to be removed through an inspection opening in a threshing mechanism housing and includes an extension formed by either a single piece or segments; a plurality of sieve lining segments; and an articulated connection between the extension and the sieve lining segments.
