Abstract: A method of measuring a harvested crop includes measuring a first attribute of a first electric field in a first volume containing crop material, measuring a second attribute of a second electric field in a second volume containing crop material, and determining at least two different properties of the crop material based at least in part on the first attribute and the second attribute.

Abstract: An agricultural machine includes a cutting assembly configured to cut a crop material, a forming assembly comprising at least one of a swathboard or a forming shield, at least one actuator configured to change a position of the forming assembly, a sensor configured to detect a yield and a moisture content of the crop material, and a controller in communication with the at least one actuator, wherein the controller is configured to change an operating parameter of the agricultural machine responsive to the detected yield and moisture content. Related methods include propelling the agricultural machine through a field, cutting a crop material with the cutting assembly, detecting a yield and a moisture content of the crop material with the sensor, and changing an operating parameter of the agricultural machine responsive to the detected yield and moisture content.

Abstract: A system for controlling a position of a pickup on a baler comprises a sensor, a processing element, and a pickup pivot mechanism. The sensor monitors a ground area, senses a presence or absence of a windrow, and outputs a sensor signal with a first level and/or data value indicating the presence of the windrow and a second level and/or data value indicating the absence of the windrow. The processing element receives the sensor signal, and outputs a pickup signal with a first level and/or data value when the sensor signal has the first level and/or data value and a second level and/or data value when the sensor signal has the second level and/or data value. The pickup pivot mechanism receives the pickup signal, lowers the pickup when the pickup signal has the first value, and raises the pickup when the pickup signal has the second value.

Abstract: A system for adjusting a tractor speed based on a performance of a pickup of a baler comprises a flow rate sensor, a processing element, and a tractor speed controller. The flow rate sensor senses a flow rate of a crop into the pickup and outputs a flow rate signal with a level that varies according to the flow rate of the crop into the pickup. The processing element receives the flow rate signal, receives a speed signal regarding a speed of a tractor pulling the baler, compares the flow rate from the flow rate signal with the speed from the speed signal to generate a comparison result, and outputs an electronic speed signal with a level that varies according to the comparison result. The tractor speed controller is configured to receive the speed signal and adjust a speed of the tractor according to the level of the speed signal.
