Abstract: A switching device for a transmission have a first and a second transmission housing portion. The switching device comprises a shift collar, a shift fork which engages in the shift collar, a control actuator which is arranged in the first transmission housing portion and an actuator rod which is connected at one end to the control actuator and at the other end to the shift fork. The actuator rod is supported in a first guiding hole which is formed in the first transmission housing portion. It is proposed that a second guiding hole which is formed in the first transmission housing portion parallel with the first guiding hole be formed and a guide rod which is orientated parallel with the actuator rod be provided and be connected at one end to the shift fork and at the other end be supported in the second guiding hole.

Abstract: Feederhouse gearboxes are provided for installation on combine harvesters. In embodiments, the feederhouse gearbox includes a gearbox housing, an output shaft rotatable about an output axis, and a primary drive input. The primary drive input is mechanically linked to an engine of the combine harvester when the feederhouse gearbox is installed thereon. A reverser drive input is mechanically linked to a reverser motor of the combine harvester when the feederhouse gearbox is installed on the combine harvester. The feederhouse gearbox further includes a selector mechanism within the gearbox housing and movable between a primary drive position and a reverser drive position, a primary gear train transmitting rotation from the primary drive input to the output shaft when the selector mechanism is in the primary drive position, and a reverser worm drive transmitting rotation from the reverser drive input to the output shaft when the selector mechanism is in the reverser drive position.

Abstract: A shield assembly for a shaft includes a first tubular section having a first end and a second end and a second tubular section having a first end and a second end. The first and second tubular sections are each hollow receiving the shaft. The first tubular section includes a first outer diameter and the second tubular section includes a second outer diameter, the first outer diameter being greater than the second outer diameter. The first tubular section and the second tubular section are telescopically coupled to one another where the second tubular section is movably disposed at least partially within the first tubular section.

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.
