  • Publication number: 20260101846
    Abstract: A deck plate control system for an agricultural harvester includes a controller having a memory and a processor. The controller is configured to identify termination of a row unit cleaning process. In addition, the controller is configured to control a deck plate actuator to transition a pair of deck plates of a row unit to an operational spacing in response to identifying termination of the row unit cleaning process.

  • Publication number: 20260083053
    Abstract: A crop loss monitoring system for an agricultural harvester includes a controller configured to receive a left sensor signal from a left sensor indicative of crop particle impacts on a left side of a row unit and to receive a right sensor signal from a right sensor indicative of crop particle impacts on a right side of the row unit. Furthermore, the controller is configured to determine whether the row unit is misaligned to a left side of a row of agricultural crops or to a right side of the row of agricultural crops. The controller is configured to determine crop loss based on feedback from the left sensor alone in response to determining the row unit is misaligned to the left side, and to determine the crop loss based on feedback from the right sensor alone in response to determining the row unit is misaligned to the right side.

  • Patent number: 12075726
    Abstract: A stalk roller assembly for an agricultural system includes a stalk roller having a hollow shaft. The hollow shaft has a first end having a first shape, such that the first end engages a guide element. Furthermore, the hollow shaft has a second end having a second shape that engages a drive shaft, such that the first shape is different than the second shape. In addition, the hollow shaft is formed from a single piece of material.

  • Publication number: 20240122110
    Abstract: An agricultural system includes a header with a feed roller configured to engage a crop and to drive material other than grain (MOG) of the crop toward a field. The agricultural system also includes a chopper configured to cut the MOG driven toward the field by the feed roller for discharge from the agricultural system and a control system configured to output a control signal to adjust a speed of the chopper relative to a speed of the feed roller based on a size of the MOG discharged from the agricultural system.

  • Publication number: 20240122108
    Abstract: An impact sensor system for a header of an agricultural system includes a first sensor vibrationally connected to a deck plate of the header, wherein the first sensor is configured to generate first signals in response to detection of vibrations due to initial contact between a crop and the deck plate of the header. The impact sensor system also includes a second sensor vibrationally connected to the deck plate of the header and positioned forward of the first sensor, wherein the second sensor is configured to generate second signals in response to detection of the vibrations due to the initial contact between the crop and the deck plate of the header.

  • Publication number: 20240122107
    Abstract: An agricultural system includes a header having a row unit with a feed roller configured to engage a crop and to pull a stalk of the crop toward the field. The header also includes a conveyor configured to receive a desirable crop material of the crop from the row unit and to direct the desirable crop material of the crop toward an inlet of the agricultural system. The header further includes a sensor system configured to detect presence of material other than grain (MOG) proximate to or at the conveyor.

  • Patent number: 11089729
    Abstract: A combine feeder assembly having conveyors and slats pivotally connected to the conveyors to rotate about respective slat pivot axes. Each slat has a paddle that is movable between a first position in which the paddle extends outside the travel path of the conveyor by a first distance, and a second position in which the paddle does not extend outside the travel path or extends outside the travel path by a second distance that is less than the first distance. A cam surface moves the slats to the first slat position along a delivery path of the conveyors. A first housing wall extends over the delivery path and is spaced from the travel path by at least the first distance. A second housing wall extends over a return path. The second housing wall is spaced from the travel path by less than the first distance.
