    Abstract: A grain paddle for a clean grain elevator of a combine harvester. The paddle includes a substantially rigid body with a planar portion having ends disposed distal and proximal to an elevator chain of the combine harvester. Some paddle embodiments include an angled end adjacent the proximal end of the planar portion. Some paddle embodiments include an angled end adjacent to the distal end of the planar portion. Some paddle embodiments include sloped lateral edges.

    Abstract: A sensor assembly for determining yield of grain harvested by a harvesting machine during harvesting operations. The sensor assembly includes a sensor housing, a displaceable sensor member and a displacement sensor. The sensor housing is mounted to the grain elevator housing above an upper sprocket of a conveyor disposed within the grain elevator housing. The sensor member is displaceably supported via the sensor housing within the elevator housing above the upper sprocket and along a direction of travel of the grain piles thrown by the conveyor flights rotating around the upper sprocket. The thrown grain piles produce a grain force on the sensor member causing a displacement of the sensor member in relation to the grain force. The displacement sensor generates a grain force signal corresponding to the displacement of the sensor member.

    Abstract: An agricultural trench depth sensing system and method includes a light source (2002), a receiver (2003) and a sensor (2004). The light source directs light downwardly toward a trench previously opened in a soil surface. The receiver is disposed at an angle relative to the light source to receive reflected light. A sensor connected to the receiver senses a pattern of the reflected light. A monitoring system in communication with the sensor, generates a data frame containing triangulated line coordinates and intensity values of the reflected light indicative of a measured depth of the trench. The generated data frame may be associated with GPS coordinates for generating spatial maps and may be used to control operating parameters. The generated data frames may also identify relative soil moisture versus trench depth, or presence of dry topsoil or residue in the trench, or to identify seeds, seed spacing and seed depth.

    Abstract: A mobile agricultural machine includes a row unit having a furrow opener mounted to the row unit and configured to engage a surface of ground over which the mobile agricultural machine travels to open a furrow in the ground. A furrow closer is mounted to the row unit behind the furrow opener and configured to engage the surface of the ground to close the furrow. A furrow sensor system is mounted to the row unit and configured to sense characteristics relative to the furrow opened by the furrow opener and generate a sensor signal indicative of the characteristics. The mobile agricultural machine can further include a control system configured to determine a furrow quality metric corresponding to the furrow sensed by the furrow sensor system based on the sensor signal and generate an action signal to control an action of the mobile agricultural machine based on the furrow quality metric.

    Abstract: An agricultural trench depth sensing system having a trench implement adapted to be disposed in a soil trench opened in a soil surface. In one embodiment an ultrasonic sensor detects a distance to an upper surface of said trench implement or a target disposed thereon. In another embodiment, said trench implement includes one or more fingers which rotate with respect to said trench implement to detect the soil surface relative to said trench implement. In another embodiment, said trench implement includes side sensors for detecting the sidewall of the soil trench.
