  • Publication number: 20230273614
    Abstract: A control system includes an agricultural output characteristic input configured to receive a progressing agricultural output characteristic of a first vehicle performing an agricultural operation. The system includes a second vehicle characteristic input having one or more second vehicle characteristics. A companion guidance controller is configured for communication with the second vehicle. The companion guidance controller includes a companion guidance line generator configured to recursively generate companion guidance line indicia based on the associated progressing agricultural output characteristic and the one or more second vehicle characteristics. A control interface is configured to communicate the companion guidance line indicia to one or more of driving or implement operation elements of the second vehicle.

  • Publication number: 20210267115
    Abstract: A guidance assembly for an agricultural vehicle includes a pathing system configured to provide an array of swaths. The guidance assembly includes a composite guidance system in communication with an automated driving interface and the pathing system. The composite guidance system includes a turn guidance system configured to guide the agricultural vehicle along at least one turn segment extending between a first zone swath and a transverse second zone swath, and a swath guidance system configured to guide the agricultural vehicle along the first zone swath and the transverse second zone swath. The system includes a comparator configured to compare the agricultural vehicle position with swath departure and arrival locations. An interswath turning element automatically toggles the turn and swath guidance systems between activated and paused configurations according to the compared agricultural vehicle position and the swath departure and arrival locations.

  • Patent number: 10260931
    Abstract: A dynamic yield monitor system includes a plurality of instruments to measure harvested crop characteristics while a crop is in-flow within a harvester elevator. The system includes a volume instrument that measures a harvested crop volume from the in-flow harvested crop within the harvester elevator, and a weight instrument that measures a harvested crop weight from the in-flow harvested crop within the harvester elevator. Optionally, the system includes other instruments including a moisture and temperature instrument. A receiver and processing node communicates with the instrument. The receiver and processing determines variable harvested crop test weight based on at least the measured harvested crop volume and measured harvested crop weight of the in-flow crop. The receiver and processing node further determines a variable yield of the harvested crop based on the measured harvested crop volume, the measured harvested crop weight, and the variable harvested crop test weight.

  • Patent number: 9372109
    Abstract: A system for measuring crop weight in a harvester elevator includes a receiver and processing node and one or more weight sensing instruments coupled to one or more paddles of the harvested elevator, respectively. The weight sensing instruments each include a weight sensor and a transmitter in communication with a receiver and processing node. The weight sensor is configured to dynamically measure the weight of a static harvested crop, relative to the sensor and corresponding paddle, as it ascends in the harvester elevator.

  • Patent number: 9310329
    Abstract: A system for measuring crop moisture content in a harvester elevator includes a receiver and processing node and one or more moisture sensing instruments coupled to one or more paddles of the harvested elevator, respectively. The moisture sensing instruments each include a moisture sensor and a transmitter in communication with a receiver and processing node. The moisture sensor is configured to dynamically measure the moisture content of a static harvested crop, relative to the sensor and corresponding paddle, at ascends in the harvester elevator.

  • Publication number: 20140277959
    Abstract: A method of automatically planting two or more seed types with an agricultural planter includes monitoring a planter location on a prescription map of an agricultural field. The planter includes one or more remotely adjustable planting characteristics. A seed type is selected based on the monitored planter location on the prescription map, the seed type including two or more seed types. The selected seed type is dispensed to one or more seed metering systems of one or more row units based on the selected seed type. As the planter moves in the agricultural one or more of the remotely adjustable planting characteristics of the planter field is dynamically changed based on at least the seed type selected according to the monitored planter location.
