A harvesting machine crop unloading spout assembly (10') comprises an unloading tube elbow (11, 12) terminating at a first end in a first flange (13) that is secured to the outlet of a harvesting machine crop tank (16). The first flange (13) includes one or more bearings permitting it to swivel about a swivel axis and the unloading tube elbow (12) includes a cranked portion terminating at a second end in an opening. The spout assembly (10) further includes a fixed member (19) that lies adjacent the unloading tube elbow (12), the unloading tube elbow (12) being connected to the fixed member (19) by way of a pivot (17') the axis of which coincides with the swivel axis. The spout assembly (10) includes a rotatable drive gear and a motor (28) drivingly engaged therewith for causing rotation of the unloading tube elbow (12) about the swivel axis, the axis of rotation of the drive gear also coinciding with the swivel axis.

A spreader arrangement (12) for an agricultural harvester (10) includes a pair of spreader discs (16), at least one cover plate (24) and a windrow chute (26). The spreader discs (16) are generally horizontally arranged and rotatable in a counter rotating manner. Each cover plate (24) is positioned at a location above a respective spreader disc (16), and is operable to inhibit a flow of crop material to the respective spreader disc (16) when positioned above the respective spreader disc (16). The spreader arrangement (12) is characterized in that the windrow chute (26) has an entrance end (30) positioned below the pair of cover plates (24) and above the pair of spreader discs (16), whereby crop material is discharged from the top of the cover plates (24) into the windrow chute (26).

A bubble-up auger for a combine harvester includes a rotatable shaft, a lower auger section either mounted to or forming part of the rotatable shaft, and an upper auger section that is removably connected to the lower auger section, and includes an opening through which the shaft is at least partially positioned. The upper auger section is moveable between a first position where the upper auger section is detached from the lower auger section and a second position where the upper auger section is connected to the lower auger section.

The present invention is related to a feeder (7) for a combine harvester (100), the feeder including a housing and a conveyor assembly (101) mounted in the housing, the conveyor assembly including a frame having lateral support arms, and moveable belts guided by sprocket wheels. The sprocket wheels are mounted on a drive shaft proximate an outlet section of the housing and on a conveyor shaft proximate an inlet section of the housing. The sprocket wheels are mounted on a drive shaft (22) proximate an outlet section (15) of the housing and on a conveyor shaft (26) proximate an inlet section (14). The conveyor assembly is equipped with a first and second tensioning mechanism, the first mechanism being configured to push the conveyor shaft forward with respect to the frame, the second mechanism including spring-operated tensioning arms (43) and tensioning rolls (42) mounted above the support arms (18,19).
