Abstract
A sieve for a grain cleaning system of an agricultural combine, including a system providing enhanced adjustability of spacing, including capacities for quickly and easily varying a number of rows of sieve fingers, spacing between the rows, and angular orientation of the fingers, such that better sieve performance, and cleaning action above the sieve, can be achieved for a particular grain or seed size and other conditions, particularly very large sizes and very small sizes.
