Abstract: A combine harvester includes a frame member, an unload tube, a pivotable cradle member and a locking device. The unload tube for expelling clean grain is moveable relative to the clean grain tank and the frame member between a stowed position and a deployed position. The pivotable cradle member is pivotably mounted with respect to the frame member for releasably receiving the unload tube. The pivotable cradle member includes a surface that is shaped for bearing on an exterior surface of the unload tube. The pivotable cradle member is pivotable between a first rotational position when the unload tube is maintained in the stowed position and a second rotational position when the unload tube is maintained in the deployed position. The locking device locks together the unload tube, the frame member and the pivotable cradle member when the unload tube is maintained in the stowed position.

Abstract: A chain guide for a wall of a grain elevator of an agricultural vehicle. The chain guide includes an elongated body. A rib extends from a surface of the elongated body, the rib being configured to engage with a chain of the grain elevator. A mating surface is either formed on or in the body, and the mating surface is configured to be connected to the wall of the grain elevator.

Abstract: An unload spout for an agricultural vehicle includes a hollow body having an inlet end for receiving crop material, an outlet end through which the crop material is distributed, and a side wall extending between the inlet end and the outlet end. A plurality of steps are formed on an interior facing side of the side wall for enhancing the structural integrity of the unload spout.

Abstract: The combine harvester includes a grain tank having a cover includes pivotable panels connected by collapsible connections so that the cover forms a funnel-shaped extension of the main receptacle of the tank when the cover is fully deployed. At least one of the panels includes an aperture and a door configured to close or open the aperture by pivoting about a pivot axis. When the cover is deployed, the door either closes the aperture and is secured thereto so that the panel has the same function as in a conventional harvester. However, when the door is opened, and supported by a support structure of the harvester, the door obtains the function of a walking plank that enables a person to walk on the plank and thereby access the interior of the tank.

Abstract: The combine harvester includes a grain cleaning section and a grain elevator, the cleaning section including one or more clean grain augers configured to deliver clean grains into the grain elevator. The harvester further includes a rotatable drive axle and a transmission system coupled thereto so that the drive axle drives the one or more augers as well as the elevator. The transmission system includes a reversible decoupler mechanism configured to decouple the one or more clean grain augers from the drive axle while not decoupling the elevator from the drive axle. These features enable removing a blockage from the grain elevator, by decoupling the one or more clean grain augers and then activating the elevator to remove the blockage, followed by the re-coupling of the one or more augers.

Abstract: A clean grain tank for an agricultural harvester includes a grain tank with a sump a vertical auger having an end that is positioned within the sump of the grain tank for removing clean grain from the sump, and at least one cross-auger arranged in a trough and configured to convey the grain into the sump. The sump is partially encompassed by walls, one of the walls including a cross-auger inlet opening facing the cross-auger and being configured to allow the grain to pass therethrough and into the sump. The cross-auger inlet opening includes a rounded segment and at least one straight segment, wherein the at least one straight segment follows a trajectory of a wall of the trough.

Abstract: A topshaft rotary antiwrap assembly includes a topshaft assembly having (i) a shaft configured for rotating about a rotation axis, and (ii) one or more sprockets mounted to the shaft concentrically to the rotation axis to move in a rotation direction about the rotation axis. The topshaft rotary antiwrap assembly also includes a first scraper body located adjacent to the topshaft assembly and has: a first sprocket scraper located adjacent to an outer perimeter of a first sprocket of the one or more sprockets and radially aligned with the first sprocket relative to the rotation axis. The first sprocket scraper includes a respective sprocket scraper body that extends from a leading edge to a trailing edge. The trailing edge is offset from the leading edge along the rotation axis such that the sprocket scraper body directs a respective adjacent portion of crop material at least partially along the rotation axis.

Abstract: An actuator assembly for moving an unload tube of an agricultural vehicle between stowed and deployed positions. The actuator assembly includes a mount that is configured to be fixed to a fixed mounting point on the agricultural vehicle. An actuator of the actuator assembly has a first end that is mounted to the mount and a second end that is mounted to the unload tube for moving the unload tube between the stowed and deployed positions. A tension rod of the actuator assembly has a first end that is pivotably mounted to the mount and a second end that is mounted to a fixed tension rod mounting point located either on or adjacent the unload tube.

Abstract: An unload tube assembly for an agricultural vehicle includes an inner tube defining a proximal end and a distal end, an outer tube extending about the inner tube, a flange disposed at the proximal end of the inner tube, and a gusset that is connected to the flange and the inner tube for supporting a weight of the unload tube assembly.

Abstract: An embodiment includes a combine including a feeder housing for receiving harvested crop, a separating system for threshing the harvested crop to separate grain from residue, a grain tank for storing the separated grain, a grain tank level sensor for detecting a level of grain in the grain tank, an inclination sensor for detecting inclination of the combine, and a controller that controls the combine. The controller configured to receive the grain tank level from the grain tank level sensor, receive an inclination value from the inclination sensor, adjust the grain tank level based on the inclination value, and alert an operator of the adjusted grain tank level.
