Abstract: A grain harvesting vehicle is configured to harvest a grain. A chaffer is configured to separate grain from material other than grain (MOG). A grate is positioned rearward of the chaffer. The grate includes a grate panel having an upper surface and a lower surface and an aperture in the grate panel extending between the upper surface and the lower surface. The aperture has a first end nearer the chaffer and a second end opposite the first end. The grate further includes a ramp portion extending above the grate panel from adjacent the first end of the aperture toward the second end of the aperture. A grain sensor has a sensing location positioned at a height below the grate.

Abstract: A row crop header for an agricultural machine harvesting a crop having stalks, such as corn. The row crop header includes a frame, a first crop row divider mounted to the frame, and a second crop row divider mounted to the frame and spaced from the first crop row divider to define a space therebetween. A row unit is disposed at the space, wherein the row unit includes a deck assembly defining a gap, the deck assembly including a compliant deck configured to adjust the gap based on contact with the stalks of the crop. The compliant deck includes a plurality of overlapping plates having edges defining the gap where the edges are configured to move responsively to varying diameters of stalks. Crops are separated from the stalks upon contact with the overlapping plates. A gathering chain moves the separated crops toward a collector.

Abstract: A feederhouse conveyor system for an agricultural harvesting machine is provided. The feederhouse conveyor system includes a power transmitting system. The power transmitting system includes first rollers, second rollers, and power transmitting bands. The power transmitting bands are configured to each transmit power between each of the first rollers and the second rollers. The feederhouse conveyor system also includes rigid cross members, configured to each attach near each end to at least one of the power transmitting bands, and flexible cross members configured to each attach near each end to at least one of the power transmitting bands. The centerlines which extend through the rigid cross members and the flexible cross members are parallel. The mat attaches to the flexible cross members by a pocket in the mat through which the flexible cross members extend.

Abstract: A work machine and a method of controlling work machine power of the work machine during a harvesting operation for harvesting a crop. The work machine may include an engine, a hybrid machine, or an electric machine. The work machine may operate by identifying a state of a driver assistance selector that includes a manual mode and an automatic mode. While in the manual mode, the work machine may operate at a nominal power target, and, when in the automatic mode, the work machine may operate at an enhanced power target for harvesting. When the driver assistance feature changes from the automatic mode to the manual mode, the transition between the enhanced power to the nominal power may be reduced over a predetermined period of time to optimize machine drivability and system performance.

Abstract: A rotary cleaning system for a combine harvester that includes a hollow drum having a plurality of apertures along at least a portion of a length of an exterior surface of the drum, the drum having a feeding end configured to receive a harvested crop and a discharge end configured to expel chaff from the harvested crop and a guiding vane positioned in an interior of the drum, wherein one of the drum and the guiding vane is configured for rotation while the other one of the drum and the guiding vane is stationary to expel grain through the plurality of apertures in the drum. A feeding mechanism can be attached to supply the crop to the hollow drum. A fan can be attached to the rotary cleaning system to generate an air flow stream. A plurality of fingers can be positioned in the drum.
