ABSTRACT:
An axle driving apparatus comprises a housing. The housing contains a hydrostatic transmission, a differential unit driven by the hydrostatic transmission, a pair of axles mutually differentially connected through the differential unit, and a restricting mechanism for selectively restricting differential motion of the axles by manual operation. The differential unit comprises a ring gear serving as an input gear and a pair of bevel gears which can be differentially rotated by rotation of the ring gear. The restricting mechanism engages one of the bevel gears with the ring gear. If a pair of differential side gears fixed on the respective axles serve as the bevel gears, the restricting mechanism engages one of the bevel gear to the ring gear through a claw clutch or a friction clutch.
