A harvester having a harvesting structure for harvesting crop and a crop receptacle for receiving harvested crop. The harvester comprises a crop conveying fan configured to operate at a fan speed to facilitate transfer of harvested crop from the harvesting structure to the crop receptacle. A control system for controlling the fan speed based on crop mass flow comprises a crop mass flow feedback device that provides a crop mass flow feedback signal indicative of crop mass flow. A controller is in communication with the crop mass flow feedback device and is configured to automatically lower the fan speed when the crop mass flow feedback signal indicates a lower crop mass flow and automatically raise the fan speed when the crop mass flow feedback signal indicates a higher crop mass flow.

System and method which automatically updates estimated field and in-transit yield values as a function of estimated vehicle load values and correction values determined from more accurate yield values obtained later, such as at a processing or other receiving facility, thereby providing better estimates of yield values between yield monitor system calibrations.

A harvester having a harvesting structure, an accumulator, and a module builder having a throat. A plurality of meter rollers are positioned to receive crop and transfer crop at a feed rate in cooperation with a beater roller. A feeder belt receives crop from the meter rollers and the beater roller and transfers the crop to the throat. A feed rate control system comprises at least one crop mass flow feedback device providing a crop mass flow feedback signal indicative of crop mass flow. A controller is provided that is in communication with the at least one crop mass flow feedback device and configured to operate in a first mode by lowering the feed rate when the crop mass flow feedback signal indicates a threshold has been reached and by raising the feed rate when the crop mass flow feedback signal indicates the threshold has not been reached.

An air system (50) for an agricultural harvester (10) includes an air flow splitter component (52) configured to be coupled to the agricultural harvester (10). The air flow splitter component (52) has an inlet (56) configured to receive air and a plurality of air outlets (58) configured to distribute the air. The air system also includes a plurality of air flow paths (60). Each air flow path of the plurality of air flow paths extends from a respective one of the plurality of air outlets and is configured to extend to a corresponding drum (12) of the agricultural harvester. Additionally, each air flow path includes a discharge outlet (80) that is configured to be disposed between a bottom surface (81) of the corresponding drum (12) and a bottom disc (85) of a doffer (42) of the corresponding drum (12) while the air system (50) is coupled to the agricultural harvester.

An agricultural harvester includes a chassis, a header carried by the chassis, and a header height control system. The header is movable in upward and downward directions. The header height control system includes an electrical processing circuit, a non-contact sensor and a contact sensor. The non-contact sensor is positioned to sense a crop canopy ahead of the header. The contact sensor is positioned to sense an actual ground position relative to the header. The electrical processing circuit is coupled with and receives signals from each of the non-contact sensor and the contact sensor. The electrical processing circuit is operable to predict an upcoming ground position based upon the sensed crop canopy and actual ground position.

A cotton doffer structure for doffing cotton snagged on a surface having debris. The cotton doffer structure comprises an extrusion. The extrusion has a longitudinal axis and a periphery with a plurality of radial protrusions. A shaft is coupled to the extrusion for rotation therewith about the longitudinal axis in a forward direction. A plurality of brushes are provided. Each brush has a base end supporting upstanding bristles, an opposing distal end, a leading side generally facing the forward direction, and an opposing trailing side. A plurality of brush support members are provided that have a leading end and a trailing end with an upright flange. The plurality of brush support members securing the base ends of the plurality of brushes against the protrusion with the upright flange located adjacent the leading side.
