Abstract
An axle driving apparatus for a small-sized vehicle, such as a tractor, which divides its axle casing into first and second axle casings. A hydraulic pump, provided with a vertical pump shaft, is disposed within one of the axle casings. A hydraulic motor, provided with a horizontal motor shaft; a speed reduction shaft; and a differential gear unit, are disposed within the other of said axle casings. This configuration allows a driving force to be transmitted from the vertical pump shaft to the horizontal motor shaft.
