Abstract: A crop unloader system comprising: an elevator assembly, a boom assembly, a flexible drive, and a tensioning assembly. The elevator assembly has a frame, an elevator drive and drive motor, and an elevator drive output. The boom assembly has a frame connected to the elevator frame at a boom pivot axis to rotate through a range of motion, and an unloader drive input. The flexible drive is operatively connected between the elevator drive output and the unloader drive input. The tensioning assembly has a tensioner link and a control link that are pivotally to each other and with one of the two links each pivotally connected to one of the boom and elevator frame. An idler wheel is on the tensioner link. The tensioning assembly maintains a tension load on the endless flexible drive within a predetermined range, throughout the range of motion of the boom frame.

Abstract: A crop unloader having a frame, an unloader tube mounted to the frame, a driven gear fixed to the unloader tube and having driven teeth extending radially from a first axis, a drive gear mounted to the frame and having drive teeth extending radially from a second axis and extending to mesh at an engagement location with the driven teeth during rotation of the drive gear about the second axis, and a motor operable to rotate the drive gear to rotate the driven gear to move the unloader tube between a first position about the first axis and a second position about the first axis. The teeth form a tapered gap at the engagement location, the tapered gap extending from an upper end to a lower end and being larger at the lower end than at the upper end. An agricultural combine having the crop unloader is also provided.

Abstract: An agricultural harvester includes a grain processing section having a sieve assembly. The sieve assembly is driven in fore and aft oscillation by an eccentric rotation device while permitting side to side movement. A drive arm to the sieve assembly has a connection interface to the eccentric rotation device permitting side to side movement during fore and aft oscillation.

Abstract: An agricultural harvester includes an auger assembly including an auger having an auger shaft defining an axis of rotation and a flighting carried by the auger shaft, the auger being configured to rotate the flighting in a sweeping path about the axis of rotation; and an auger trough placed adjacent to the auger to hold crop material in the sweeping path and having a bottom below the sweeping path. The auger trough has a first portion on a first side of the bottom and a second portion on a second side opposite the first side of the bottom, with the second portion of the auger trough having an end directed toward the first portion in a direction of the sweeping path.

Abstract: A method of controlling a conveyance rate of grain of an unloader system, including providing a grain holding device and an unloader in communication with the grain holding device, the unloader having an inlet for receiving grain from the grain holding device and an outlet for discharging grain. An apparatus within the grain holding device is operable for controllably feeding grain within the grain holding device to the unloader. The method includes monitoring a parameter associated with a power source of the apparatus, and comparing the parameter of the power source to a maximum predetermined threshold value. The method includes automatically controlling the conveyance rate of grain of the apparatus to the unloader.
