A drive system for the internal combustion engine of a large work vehicle, such as a self-propelled agricultural combine. The drive system comprising three concentric drive shafts that are housed in a housing for driving three separate usage assemblies. The outer and middle drive shafts are provided with bevel gear assemblies having output axes perpendicular to the drive shafts axis. The bevel gear assembly of the outer drive shaft is coupled to a series of four sequentially mounted hydraulic pumps, whereas the bevel gear assembly of the middle drive shaft is coupled to a forwardly extending drive shaft. An internal clutch is provided for operatively engaging and disengaging the middle drive shaft from the drive train.

A drive system for supplying power to at least three separate usage assemblies, the drive system comprising: a prime mover providing rotational power; an inner drive shaft which is operatively coupled to the prime mover, the inner drive shaft defining a drive axis; a hollow middle drive shaft is concentrically arranged about the inner drive shaft, the second drive shaft is operatively coupled to the prime mover; a hollow outer drive shaft is concentrically arranged about the middle drive shaft, the outer drive shaft is operatively coupled to the prime over; and means for operatively coupling the inner drive shaft to a first usage assembly, a second bevel gear assembly for operatively coupling the middle drive shaft to a second usage assembly, the second bevel gear assembly having an output member for transmitting rotational power outwardly from the drive axis, and a first bevel gear assembly for operatively coupling the outer drive shaft to a third usage assembly, the first bevel gear assembly having an output member for transmitting rotational power outwardly from the drive axis, whereby the first and second bevel gear assemblies are nested together so that the output members of each bevel gear assembly lie on opposite sides of the inner drive shaft.
