A chaff feed stream conditioning system (40) for installation in a combine having a crop residue handling system (10) that operates to separate crop residue into a straw feed stream (20) and a chaff feed stream (20) which may include weed seeds. The straw feed stream (20) is directed to flow towards a straw spreader or chopper (22) or is windrowed. The chaff feed stream (28) is directed to flow toward a mechanical devitalisation system (30) or other processor. The chaff feed stream conditioning system (40) comprises one or more components or devices such as a separator mechanism (42) and/or magnets M1-M3, distributed from a downstream of the crop residue handling system through to an upstream end of the chaff feed stream (28) and configured to impede straw or other foreign matter from getting into the flow of chaff feed stream or otherwise reaching a downstream end of the chaff feed stream.

A preparation section of a combine harvester that is configured to receive a mixture of grain and material other than grain (MOG) from a threshing section of the combine harvester. The preparation section includes a conveyor positioned beneath the threshing section that is configured to transport the grain and MOG in a downstream direction toward a cleaning section, and a deflector positioned at a downstream end of a conveyor that is configured to launch the grain and MOG into the air and cause at least partial separation of the MOG and grain prior to falling onto the cleaning section.

A system and method for conveying agricultural material in a harvester. One harvester includes a rotor which rotates to separate a plant into a first agricultural material and a second agricultural material. A grate is disposed vertically below the rotor and further separates the first and second agricultural materials from one another. A first conveyor receives the first and second agricultural material directly from a trailing end of the rotor and a trailing end of the grate.
