A windrowing work vehicle with a swath flap arrangement is disclosed. The swath flap arrangement includes a swath flap that is supported for movement by a support structure between a raised position and a lowered position. The swath flap is configured to at least partially shape a windrow of a crop material. A method includes receiving, by a processor of a control system from a memory element, a stored position setting that corresponds to a position of the swath flap relative to the support structure. The method further includes processing, by the processor, a positioning control signal based, at least in part, on the stored position setting. Also, the method includes moving, with an actuator, the swath flap relative to the support structure between the raised position and the lowered position according to the positioning control signal.

A harvester includes: a crop tank that stores a crop harvested by a harvesting device; a weight detection unit that detects a storage weight, which is a value indicating the weight of the crop stored in the crop tank; a maximum weight calculation unit that calculates a maximum weight, which is a value indicating the weight of the crop at the maximum storage amount of the crop tank; a unit harvest weight calculation unit calculates a unit harvest weight that indicates the weight of the crop harvested per unit of harvest-travel distance; and a maximum travel distance calculation unit that calculates a maximum travel distance, which is the maximum distance that can be traveled during traveling harvesting before the amount of the crop stored in the crop tank reaches the maximum storage amount, based on the storage weight, the maximum weight, and the unit harvest weight.

Systems for harvesting machines, transmissions for harvesting machines, and methods of operating systems for harvesting machines are disclosed herein. A system includes a drive unit, a cleaner unit, an aspirator, and a transmission. The drive unit is configured to produce rotational power in use of the system. The cleaner unit is fluidly coupled to the drive unit and configured to separate debris from air so that the air becomes cleaned air and provide the cleaned air to the drive unit in use of the system. The aspirator is fluidly coupled to the cleaner unit and configured to draw debris away from the cleaner unit and exhaust the debris in use of the system. The transmission is coupled to the drive unit and the aspirator.

A cam assembly is provided for a pick-up reel of an agricultural harvester. The cam assembly includes a cam track, a roller bearing assembly, a crank arm, and a biasing member. The roller bearing assembly includes a baffle and first and second cam followers. The first and second cam followers are each mounted to the baffle in spaced apart relation and engaging the cam track. The crank arm is for mounting to the pick-up reel. The biasing member biases the roller bearing assembly relative to the crank arm.

A combine harvester tailings return system includes a tailings conveyor and an ejection channel for depositing tailings upstream of a cleaning system. A proximity sensor is mounted to the ejection channel and is configured to sense the height of a layer of tailings during transit through the returns system.

A tilt-sensing apparatus for a vehicle, comprising: a controller; and a motion tracker, wherein the controller is configured for communication with the motion tracker and a display, wherein the motion tracker is configured for attachment to a vehicle at a position remote to the display and comprises a first tilt sensor configured to measure a first tilt angle with respect to a first axis and a second tilt sensor configured to measure a second tilt angle with respect to a second axis, wherein the controller is configured to receive data via an output of the motion tracker, said data comprising the first tilt angle and the second tilt angle, and communicate an instruction to the display to display a graphical representation indicative of the first tilt angle and the second tilt angle, and associated method.

A combine harvester with a variable length wheelbase. For example, a combine harvester may have a chassis defining a forward end and a rear end, a feeder house at the forward end of the chassis, a first set of ground-engaging elements supporting the forward end of the chassis, and a second set of ground-engaging elements supporting the rear end of the chassis. The second set of ground-engaging elements are configured to move forward and rearward relative to the chassis.

A method and an arrangement for control of the speed of a baler includes detection and mapping of one or more of a crop property and data derived therefrom during the harvesting of a field by a combine harvester. Crop residues are deposited in a windrow in the field. The method and arrangement control the speed of the baler in the pickup of the windrow while taking into account one or more of the mapped crop property and the data derived from the crop property.

A self-cooling system includes at least one rotating component and a housing configured to enclose the at least one rotating component. The housing includes at least one inlet bore and at least one exhaust bore. The at least one exhaust bore is disposed radially outward from a radial position of the at least one inlet bore with respect to an axis of rotation of the at least one rotating. The at least one inlet bore and the at least one exhaust bore are positioned to establish a pressure differential configured to circulate a fluid into the at least one inlet bore, through the housing, and out the at least one exhaust bore. The system does not have any feature in addition to the at least one rotating component configured to drive the fluid into the at least one inlet bore, through the housing, and out the at least one exhaust bore.
