Abstract

See full text

A sieve for a grain combine has a plurality of longitudinal sections. Each section is pivotally mounted in a sieve frame. A sensing means senses if the combine is leaning to one side. The sensing means controls a drive and linkage mechanism for pivoting each of the sections relative to the sieve frame to maintain each section generally horizontal. Elastomeric seals extend between each of the sections.
