Patent ID: 11324168

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.
