Abstract
A cleaning system for an agriculture work vehicle including a combination of a grain cleaning sieve having a limited region containing larger apertures providing increased grain throughput and also increased air throughput relative to the other regions of the sieve, utilized with a fan system that provides a substantially higher air flow rate through the region relative to the other regions of the sieve, such that a downward airborne flow of crop material above and flowing toward the limited region is subject to an air flow having a substantially higher flow rate compared to the other regions above the sieve, which operates to aggressively separate material other than grain from the grain above the limited region, and such that substantially only grain will fall onto and pass through the limited region of the grain cleaning sieve.
