The brake system comprises a braking gear(20) for supplying braking force to an output shaft(14), a first braking member(30) for braking the braking gear(20), an operating means(40) for operating the first braking member(30) and a third braking member(16A) for braking a speed change gear(16) selectively, and a controlling means(50) for controlling the operating means(40). The braking gear(20) meshes continuously with a driving gear(15) and is coaxially aligned with the output shaft (14). The first braking member(30) brakes the braking gear(20) to connect or disconnect the supply of power from a driving shaft(13) to the braking gear(20). The controlling means(50) receives a braking signal generated by a braking treadle (60) and controls the operating means(40) in order to disconnect the supply of power from the driving shaft(30) to the speed change gear(16) and brake the braking gear by an operation of the first braking member(30).
