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 mobile machine is described. In one example, the machine includes a first subsystem comprising propulsion components configured to propel the mobile machine, a second subsystem, a first drive mechanism, a second drive mechanism, a coupling mechanism, and a controller configured to actuate the coupling mechanism to selectively couple one of the first or second drive mechanisms to drive one or more components of the second subsystem with variable speed and direction.

Abstract: A harvester reciprocating drive balancing system may include a crop material separating member movably supported for reciprocal movement and a drive operably coupled to the crop material separating member to reciprocate the crop material separating member. The drive may include a drive crank operably coupled to the crop material separating member, a shaft operably coupled to the drive crank, a belt drive, a driven pulley, a belt wrapped about the belt drive and the driven pulley and a gear reduction mechanism operably coupled between the driven pulley and the shaft.

Abstract: An example agricultural harvesting machine includes a header and a feed system configured to feed material from the header through a threshing section along a conveyance path. The feed system includes a conveyance mechanism that conveys the material from the header to a rotating feed mechanism. The feed system also includes a drive system configured to rotationally drive the feed mechanism during a first state to convey the material along the conveyance path, and to reverse rotation of the feed mechanism during a second state. In one example, a drive system includes first and second drive mechanisms and a coupling mechanism configured to selectively couple one of the first or second drive mechanisms to an output mechanism, such as, but not limited to, a rotating feed mechanism in an agricultural harvesting machine.

Abstract: A belt tension control system may include a first belt engager to engage a first portion of a belt extending between and on a first side of first and second pulleys and a second belt engager to engage a second portion of the belt extending between and on a second side of the first and second pulleys. The first belt engager is movably supported so as to move in response to changes in tension of the first portion of the belt. The second belt engager is movably supported so as to move in response to changes in tension of the second portion of the belt. The first belt engager and the second belt engager are connected by a linkage such that movement of the first belt engager towards the first portion of the belt automatically retracts the second belt engager away from the second portion of the belt, wherein the linkage automatically maintains a constant ratio of belt tension of the first portion to belt tension of the second portion.
