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. A distributor at the forward end of the sieve has a pair of sprockets and a chain extending perpendicular to the longitudinal axis of the sieve. Fingers protrude longitudinally from the chain. The chain is driven when the combine leans. |
