摘要

1. A combine harvester comprising a residue management system having a chaff spreader pivotally mounted proximate to a cleaning shoe ejection zone, the chaff spreader being pivotable about a transverse pivot axis between a spreading position and a non-spreading position, wherein, in the spreading position, the chaff spreader is configured to collect chaff ejected by a cleaning shoe, and a straw chopper mounted in the vicinity of a straw ejection zone and behind the chaff spreader, the straw chopper being moveable between an operating position and a non-operating position, and a mechanical linkage connecting the chaff spreader and straw chopper, wherein movement of the straw chopper from the operating position to the non-operating position is translated into pivoting of the chaff spreader from the spreading position to the non-spreading position.
