A crop feed rate control system provides crop processing data to a vehicle control system. The crop feed rate control system includes one or more feedback systems that operably provide a feedback signal including data indicative of a detected load amount for crop processing components of the crop processing system and indicative of a target load amount for the crop processing components. A first control module receives the feedback signal and generates a controlling load signal based at least upon the feedback signal, the controlling load signal being indicative of a controlling component of the crop processing components. A second control module receives a targeted load signal and the controlling load signal, the second control module operably generating crop processing data indicative of a target harvesting rate.

Crop feed rate control system for a harvester vehicle

One or more techniques and/or systems are disclosed for a harvester vehicle that includes a crop processing system comprising at least an accumulator and a round module builder. The harvester vehicle has a feedback fusion system that operably provides crop processing data indicative of an estimated accumulator fill level to a crop feed rate control system. The feedback fusion system has a plurality of feedback devices that operably provide feedback signals including data indicative of two or more of: crop mass flow, module builder status, module size, and accumulator fill level. The feedback fusion system has a control module that operably receives the feedback signals and generates an accumulator fill level signal based at least upon two or more of the feedback signals. The accumulator fill level signal is indicative of the estimated fill level in the accumulator.

Sensor fusion system for improved accumulator fill level in a harvester vehicle

A cotton harvester estimates the mass of cotton as it is harvested using sensor devices and compares the mass of each module against the estimated mass of the module as determined by the sensors so that a calibration factor may be determined and actively updated for more accurate crop yield determination. The mass flow for a specific module is accumulated and processed during harvesting using a base calibration factor and the module is weighed and compared against the expected mass using the base calibration factor to develop a candidate updated calibration factor. The base calibration factor is selectively replaced by the candidate updated calibration factor for processing a subsequent module based on machine feedback information relating to the operation of the harvester. Harvested crop data determined using the calibration factor is used to generate highly accurate yield maps.

Crop yield determining apparatus

A sensor input is detected on a cotton harvester. A performance characteristic value is identified based upon the detected sensor input. A speed control system controls cotton harvester drum speed and spindle speed, automatically, and separately from the ground speed of the cotton harvester, to improve the performance characteristic value, in a closed-loop fashion.

A crop sensing system for a baler includes a compression system for forming a bale and a feed system for picking up crop from a surface and conveying the crop to the compression system. The crop sensing system includes a sensor arrangement having at least one sensor being coupled to at least one of the compression system or the feed system, wherein the at least one sensor generates a signal corresponding to a crop load on the at least one of the compression system or the feed system. The crop sensing system includes a control unit configured to receive the signal from the sensor arrangement and calculate crop mass data based on at least the signal.

A bale information system includes a baling machine configured to process a material into a bale, the baling machine including a sensor configured to measure a release of the bale from the baling machine, a global positioning system receiver in operable communication with the baling machine, and a data storage system operable to receive and store data from the global positioning system receiver.

Baler information system and method

A baler having a compression system for forming a bale. The baler also has a feed system having a pack mode for accumulating the crop in a pre-compression chamber and a lift mode for conveying the crop to the compression system. The baler also has a sensor arrangement having at least one sensor generating a signal, the at least one sensor being coupled to the feed system. The signal corresponds to a crop load on the feed system. A control unit is configured to receive the signal from the sensor arrangement and initiate the lift mode based on at least the signal.

A harvester generates a round module and positions the round module on a handler. The handler includes a cylinder having a base end and a rod end. A differential pressure across the cylinder is detected. A round module weight is generated based on the detected differential pressure.
