Abstract
A sieve for a harvester thresher which consists of a frame and adjustable louvers that are mounted therein and can be adjusted by a motor-driven adjusting drive, wherein the sieve consists of at least two sieve elements that are arranged in the same plane and are respectively provided with a frame. In order to prevent the play of the adjusting drive and to adjust the louvers of the sieve elements independently of one another, separate adjusting drives are assigned to the sieve elements.
