A dust management system for an agricultural harvester includes a perforated tube extending transversely through a feeder housing of the harvester. The perforated tube has exhaust plenums at opposite ends directing any flow towards the ground over which an agricultural harvester operates. A longitudinal drive shaft mounts axial flow fans within the exhaust plenums and a drive shaft is driven through a pulley system so that rotation of the drive shaft induces flow through the perforated tube and out of the exhaust plenum.

A feederhouse assembly for an agricultural harvester includes a feederhouse comprising an inlet end, a rotational shaft coupled to the feederhouse and defining a plurality of fluid passages therethrough, and a frame adjacent the inlet end and arranged to pivot about the rotational shaft relative to the feederhouse. The frame defines a crop opening therethrough and is configured to carry a harvesting header. An agricultural harvester includes a chassis, the feederhouse assembly mounted to the chassis, and a processing system carried by the chassis and structured to receive crop material from the feederhouse.

A header positioning assembly for adjusting a header relative to a chassis includes a lift mechanism configured to couple the header to the chassis, at least one lift actuator configured to apply a force to the lift mechanism to adjust and maintain an orientation of the lift mechanism relative to the chassis, and an adjustment mechanism coupled to the at least one lift actuator or to the lift mechanism. The adjustment mechanism is positionable in at least two orientations and configured so that when the adjustment mechanism is in the at least two orientations, and without uncoupling the adjustment mechanism from the at least one lift actuator or the lift mechanism to which the adjustment mechanism is coupled, the adjustment mechanism changes one or more of a location and a direction of the force applied to the lift mechanism by the at least one lift actuator.

A system for a header assembly that has a center frame configured to pivot relative to an adapter frame about at least one center axis, a center actuator coupled to the center frame to selectively provide a biasing force thereto, a first arm assembly configured to pivot relative to the center frame about at least a first arm axis, a first actuator coupled to the first arm assembly to selectively provide a biasing force thereto, a controller in communication with the center actuator and the first actuator to selectively alter performance characteristics of the center actuator and the first actuator, and a user interface in communication with the controller and having at least a first option and a second option. Wherein, the controller adjusts the performance characteristics of both the center actuator and the first actuator when the user interface is transitioned between the first option and the second option.

An agricultural machine includes a chassis, a crop-cutting member coupled to the chassis; and a crop-conditioning member coupled to the chassis and positioned rearward of the crop-cutting member. The crop-conditioning member includes a first macerator assembly and a second macerator assembly. The first macerator assembly includes a first roll configured to rotate about a first rotational axis, a second roll configured to rotate about a second rotational axis, and a first endless member surrounding and engaged with the first roll and the second roll. The second macerator assembly is spaced apart from the first macerator assembly; and a maceration zone is defined between the first macerator assembly and the second macerator assembly. The endless member rotates to macerate crop disposed between the first macerator assembly and the second macerator assembly.
