Disclosed herein is a diagnostic module configured to determine an average image of a set or a sequence of collected images, to obtain a last image of the set or the sequence of collected images, and to determine a difference between the average image and the last image to yield a differenced image. Background image data or background pixels are eliminated from the differenced image to produce an initial image mask of unchanged content in the last image. A diagnostic module or data processor determines a mask area of the initial image mask or a revised image mask derived from the initial image mask. A diagnostic module or data processor generates an alert data message to inspect or clean the imaging system if the mask area exceeds a threshold area.

A combine for reaping culms in a field while traveling, and accumulating, in a grain tank 2, grains obtained by threshing reaped culms, includes: a yield calculator for calculating a yield per unit of travel, which is a yield per unit of travel distance; a work travel determiner 53 for determining non-harvest work travel that does not involve grain harvesting, and harvest work travel that involves grain harvesting; a harvest map data generator 66 for generating harvest map data in which the yield per unit of travel, a travel route on which the combine has traveled in a field, and a result of determination performed by the work travel determiner are associated with one another; and a harvest information recorder for recording the harvest map data.

A threshing system for an agricultural harvester includes a rotor and a substantially cylindrical cage that surrounds at least a portion of the rotor. The threshing system also features a material flow adjustor for controlling axial movement of material through the cage. The material flow adjustor is movably mounted adjacent to a threshing space and includes at least one material conveying edge that enters the threshing space. The material flow adjustor is moveable between a first operative position, in which the at least one material conveying edge is spaced from the rotor in a radial direction by a first distance, and a second operative position in which the at least one material conveying edge is spaced from the rotor in the radial direction by a second distance, the second distance being less than the first distance.

Disclosed herein is a system for evaluating agricultural material which comprises, in one embodiment, a housing having a passage in or through an interior of the housing with an inlet for receiving agricultural material and an outlet for outputting the agricultural material. The system further comprises a wall opening in a wall of the passage. An imaging device having a lens is located inward from a border of the imaging device. The imaging device is pivotally mounted for rotation with respect to a housing such that in a closed state the border of the imaging device rests on, engages or interlocks the wall opening of the housing, and in an open state the border exposes the wall opening and an interior of the housing.

A liner panel for a transition cone of a farm combine is provided. The liner panel is configured to absorb abrasive forces caused by crop cuttings moving across an inner surface of the transition cone. The liner panel includes an upper edge having a length. A lower edge is positioned opposite the upper edge and has a length that is smaller than the length of the upper edge. Opposing side edges are connected to the upper edge and lower edge. The upper edge, lower edge and opposing edges cooperate such that the liner panel has a tapered shape.

A harvester grain unloading auger may have auger flights within an unloader housing, wherein a discharge speed adjustment mechanism is coupled to the unloader housing to receive grain from the grain unloading auger at a first speed. The discharge speed adjustment mechanism discharges the grain at a second speed greater than the first speed.
