Abstract: A row unit assembly for use with a corn harvester includes a first drive having an output shaft, a stalk roll that extends along a first axis and rotates about the first axis via the output shaft of the first drive. A second drive rotates a first drive member about a second axis that is substantially perpendicular to the first axis. A first conveyor extends around the first drive member and moves about the first drive member in response to rotation of the first drive member. A third drive rotates a second drive member about a third axis that is substantially parallel to the second axis. A second conveyor extends around the second drive member and moves about the second drive member in response to rotation of the second drive member.

Abstract: An agricultural harvesting head having an elongate frame, a rear wall, side conveyors and a center conveyor. The side conveyor having an endless belt conveyor with an endless recirculating belt supported on an idler roller and a drive roller. The side conveyor is driven by an endless drive belt nested within the endless recirculating belt.

Abstract: A corn head row unit gearbox includes an input shaft, that rotates about a first axis of rotation and that drives a set of gears. The gears transfer rotation of the input shaft into rotation of a gathering chain output shaft about a second axis of rotation, generally transverse to the first axis of rotation. The gathering chain drive shaft rotates within a bushing mounted within a frame structure of the gearbox. A bushing seal has an annular mounting sleeve with an inner diameter that is press fit over a boss on the frame structure.

Abstract: A corn head row unit gearbox includes an input shaft, that rotates about a first axis of rotation and that drives a set of bevel gears. The bevel gears transfer rotation of the input shaft into rotation of a set of gathering chain output shafts about a second axis of rotation, generally transverse to the first axis of rotation. The gathering chain drive shafts each rotate within a bushing mounted within a frame structure of the gearbox. The frame structure defines a bore that communicates with a bevel gear cavity, in which at least one of the sets of bevel gears rotates, and an interior of the bushings mounted on the gathering chain drive shafts. Rotation of the bevel gears carries lubricant to an inlet aperture on the bore and drives the lubricant through the bore into the bushings.
