A mechanism for powering a combine header unit at infinitely variable speeds. A primary motor is coupled to a primary input shaft via a clutch, a variable-speed secondary motor is directly coupled to a secondary input shaft, and the header unit coupled to a header output shaft. A planetary gear-train couples the primary input shaft, the secondary input shaft, and the header output shaft to each other. A primary brake is coupled to the primary input shaft, and a secondary brake coupled to the secondary input shaft. A control circuit is employed to command the operation of the clutch, the secondary motor, the primary brake, and the secondary brake in response to operator commands.

A power transmission assembly for an agricultural machine includes a gearbox having an input shaft, and a torque sensing assembly having an axially fixed sheave, an axially movable sheave, a cam assembly interposed between the axially fixed sheave and the axially movable sheave, and a spring assembly coupling the axially movable sheave to the axially fixed sheave. The axially fixed sheave includes a hub portion having a tapered face extending increasingly outward from an inside diameter to engage a beveled shoulder of the input shaft. A nut is engaged with a threaded end of the input shaft, such that when tightened the nut forces the tapered face of the axially fixed sheave into engagement with the beveled shoulder of the input shaft.
