A control system for controlling a motion of an auger tube of a combine harvester comprises a dynamic pre-filter, a position controller, and a speed controller. The dynamic pre-filter receives a desired position value for the auger tube and generates a filtered desired position signal which changes the desired position value from an old value to a new value over a time period. The position controller receives a first difference between the filtered desired position signal and an actual position of the auger tube. The position controller generates a desired angular speed signal that varies according to the first difference. The speed controller receives a second difference between the desired angular speed signal and an actual speed of the auger tube. The speed controller generates an actuator signal that varies according to the second difference and is received by an actuating system that moves the auger tube.

A grain measuring device 10 includes a reaping determination unit 11 in a combine harvester 1 to determine a state of reaping grains; and a measurement unit 12 configured to measure a component of the grains and save a result of measurement when the reaping determination unit 11 determines that the combine harvester 1 is in in the state of reaping the grains.

An agricultural harvester includes a cutting head configured to harvest an agricultural material, a transfer mechanism configured to transfer the harvested agricultural material from the agricultural harvester, and a fill management system. The fill management system is configured to provide open-loop control of an automated transfer of the agricultural material from the agricultural harvester. The fill management system includes a controller, a user interface module coupled to the controller and configured to receive user input indicative of a selected nudge direction, and a wireless communication module coupled to the fill management system and configured to communicate wirelessly with a receiving vehicle.

At least one of the first portable electronic device and the second portable electronic device is configured to receive a geographic position of the other portable electronic device and, using only the first geographic position and the second geographic position, identify a harvesting operation performed by the agricultural harvester; determine a harvesting distance, a harvesting duration of time, or both of the harvesting operation; and estimate a current fill level of the crop transport vehicle based on the harvesting distance, the harvesting duration of time, or both.

A method for facilitating calibration of a yield monitor, including receiving, via a controller of a yield monitor calibration system, a first signal indicative of a first weight value from a scale of the yield monitor calibration system, wherein the scale is configured to monitor weight of harvested crops in a mobile storage compartment configured to receive the harvested crops from a harvester during an unloading operation. The method also includes receiving, via the controller, a second signal indicative of a second weight value from the scale in response to receiving a third signal indicative of the harvester completing the unloading operation, comparing, via the controller, the first weight value to the second weight value to determine a difference value, as well as outputting, via the controller, the difference value to the yield monitor to enable the yield monitor to perform a calibration process.

An arrangement for data recording and sampling for an agricultural machine includes a sensor set-up arrangement to detect properties contained in a material stream, means of taking a sample of the material from the material stream, and an electronic control unit. The control unit is configured to perform the following steps in response to a tripping signal: (a) instruct an actuator to bring the means into a position for sampling; (b) starting a recording of raw sensor arrangement data in a memory; (c) after depositing the sample at a desired sampling location, stop recording the raw data and instruct the actuator to return the means from the sampling position to an inactive position; and (d) store identification data to identify the sample together with the raw data in memory.
