Abstract: A system for controlling the aggressiveness of a tailings processor that re-threshes tailings received from the grain cleaning system in an agricultural harvester is provided with at least one imaging device to image a grain sample. At least a portion of the grain sample has at least once passed through the tailings processor. A controller is connected to the imaging device and to an arrangement to automatically adjust the aggressiveness of the tailings processor. The controller is configured to automatically adjust the aggressiveness of the tailings processor using the arrangement, based on based on the level of broken grain and/or unthreshed grain determined from the image from the at least one imaging device by comparing the level of broken grain and/or unthreshed grain to the desired level.

The system including a grain tank configured to receive harvested grain, a sensor configured to emit a sensor beam into the grain tank for reflection off of the top surface of the harvested grain, and a reflective target integrated into a bottom surface of the grain tank at a minimum detectable grain level within the grain tank. The bottom surface of the grain tank being angled towards the sensor, the minimum detectable grain level being defined by a minimum grain level within the grain tank at which the top surface of the harvested grain is contacted by the sensor beam, and the reflective target being configured to reflect the sensor beam when the current grain level is vertically below the minimum detectable grain level.

Abstract: A foldable auger having a first and second auger assemblies, each having a respective housing, auger screw and rotation axis. A pivot joins the assemblies, and is configured to permit the second auger assembly to fold relative to the first auger assembly. A first drive coupler is located at an end of the first auger screw and offset from the first axis, and a second drive coupler is located at an end of the second auger screw and offset from the second axis. A drive sleeve is rigidly connected to the end of the second auger screw. The drive sleeve has at least one slot that slidingly receives the second drive coupler. The second drive coupler is movable between a first position in driving connection with the first drive coupler, and a second position not in driving connection with the first drive coupler.

Abstract: An unloading auger locking mechanism for use by an agricultural harvester, allowing the secure retainment of an unloading auger while it is in its stored position, accomplished by the passive locking between a latch assembly mounted on the unloading auger and an actuated hook assembly on the chassis, further allowing the unlocking of the mechanism by remote actuation. Locking and unlocking of the unloading auger can therefore be accomplished without the operator leaving the cab.

Abstract: A system for sensing harvested crop levels within an agricultural harvester may include a crop tank configured to receive harvested crop. The system may further include a sensor configured to emit a sensor beam into the crop tank for reflection off of the top surface of the harvested crop. Additionally, the system may include a reflection panel positioned at a minimum detectable crop level within the crop tank. The reflection panel may be configured to reflect the sensor beam when the current crop level is vertically below the minimum detectable crop level. A center of the reflection panel may be positioned closer to the sensor than an outer edge of the reflection panel such that the reflection panel diffuses the sensor beam as it reflects off of the reflection panel.

Abstract: A grain tank level sensing system for a combine which harvests grain. The combine includes an upwardly open grain tank fillable with harvested grain and a cover that is displaceable for closing off the open grain tank. An actuator displaces the cover between an open and close position and either single or dual ultrasonic sensors continuously detect the level of grain in the tank and generate a signal proportional to the level of grain in the grain tank. A control system receives the signal from the ultrasonic sensors and generates an indication of the level in the tank to a monitor and/or disables the actuator to initiate the closing function when the grain tank is full.
