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.

Systems and methods of controlling operation of a diesel engine using feedforward load anticipation. An electronic controller determines a difference between an actual engine speed value of the diesel engine and a desired engine speed value, and generates a feedback control command based on the determined difference. In response to detecting one or more conditions indicative of an anticipated mechanical load event that will alter a total mechanical load of the diesel engine, the electronic controller applies a feedforward offset to the feedback control command in accordance with a feedback offset function. The feedback offset function causes the magnitude of the feedback offset to decrease over a period of time until the offset returns to zero (i.e., a signal decay function). The diesel engine is then operated based on the feedback control command and the feedforward offset.

A separator module for an agricultural machine. The separator module includes a feederhouse configured to receive crop from a harvesting platform, a casing enclosing a rotor positioned therein and rotatable relative to the casing for processing crop from the feederhouse, a cover extending between the feederhouse and the casing, and a noise control treatment coupled to the cover.

A rotor assembly for harvesting a crop. The rotor assembly has a rotating portion defined along a rotation axis, a surrounding assembly at least partially surrounding the rotating portion, the surrounding assembly having at least one separation grate coupled to a support. The support defines an inner surface and has at least one interrupter receiver. The at least one interrupter receiver is selectively coupleable to an interrupter to position the interrupter radially inward of the inner surface towards the rotation axis.

A crop residue spreader for an agricultural crop harvester such as a combine includes a rotor having a plurality of paddles including a first paddle having a first cross-sectional shape and a second paddle having a second cross-sectional shape, the second cross-sectional shape of the second paddle being different from the first cross-sectional shape of the first paddle. Different V-shapes can be used for the first and second cross-sectional shapes, the openings of the V-shapes facing in a forward rotational direction of the rotor. Multiple pairs of similarly shaped paddles can be used.

A cleaning system for an agricultural combine includes a cleaning shoe including a chaffer having an upstream extremity and a downstream extremity, a cleaning fan for establishing a flow of air upwardly through the chaffer, and a transverse chaffer dam mounted proximate to the downstream extremity transversely obstructing a crop layer flow path extending over the chaffer from the upstream extremity to the downstream extremity while permitting air and threshed crop material to flow thereover and thereunder through a transverse opening between the chaffer dam and the downstream extremity.

A harvester includes a chassis, a separation frame movably supported by the chassis and upon which crop material is deposited, a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame, a control system, a sensor programmed to produce a signal indicative of a tilt of the chassis relative to a gravitational direction, and programmed to provide the signal to the control system, and an adjustable link operably coupled between the separation frame and the chassis to adjust a pivot point of the separation frame. The control system is programmed to determine a change in tilt of the chassis based on the signal from the sensor. The controller is programmed to adjust the adjustable link to modify the pivot point of the separation frame in response to the change in tilt of the chassis.
