Abstract: A sensing system and method is provided for crop material in a harvester. The sensing system includes a conveyor auger device oriented in a substantially vertical direction and having an entrance aperture, an exit aperture located upwardly above a radially oriented sensing aperture disposed therebetween. The conveyor auger device includes a conveyor auger having a flight for moving crop material upwardly, wherein the flight has a reduced radial extension adjacent the sensing aperture. A sensor disposed at or adjacent the sensing aperture senses the essentially continuously upwardly moving crop material for determining a property thereof.

Abstract: A shroud (102) for an aftertreatment device (100) for treating exhaust gas from an internal combustion engine comprises a stepped conduit (126) configured to be disposed over an upper surface of the aftertreatment device (100) and extending over substantially the entire length of the aftertreatment device (100), wherein the stepped conduit (126) is configured to channel a flow of cleaning air longitudinally along the outer and upper surface of the aftertreatment device (100), wherein an inner surface of the stepped conduit (126) defines at least a first downwardly extending step (134, 136, 138) and a second downwardly extending step (134, 136, 138) that are spaced apart along the length of the aftertreatment device (100), to direct at least a portion of the flow of cleaning air downward.
