Chaff pan arrangement for a combine harvester

Abstract

A combine harvester includes a cleaning system having an upper sieve and a lower sieve for separating chaff from clean grain. The upper sieve and the lower sieve are arranged for oscillating in a fore-to-aft manner. The combine harvester further includes a residue spreader, arranged for receiving separated chaff from the cleaning system and for spreading the separated chaff over a field. The combine harvester further includes a chaff pan, mechanically mounted to the upper sieve for oscillating in a fore-to-aft manner therewith, in a position downstream of the upper sieve and upstream of the residue spreader for conveying the separated chaff from the upper sieve to the residue spreader; and a chaff pan side shake system, arranged to oscillate the chaff pan in a side-to-side manner.
