Abstract
A sieve for a cleaning system of an agricultural harvester includes: a sieve frame defining a top side; adjustable louvers carried by the sieve frame and defining apertures; an adjustment bar coupled to the adjustable louvers such that displacement of the adjustment bar changes a size of at least some of the apertures; and an adjustment assembly. The adjustment assembly includes: an adjustment arm coupled to the adjustment bar and pivotable relative to the sieve frame such that pivoting of the adjustment arm about a pivot axis displaces the adjustment bar. The adjustment arm carries a locking pin. A shaft is disposed on the top side and coupled to the adjustment arm. Displacement of the shaft from a first position to a second position causes a corresponding displacement of the locking pin from a locking position to an adjustment position.
