To provide a working machine of improved work efficiency attained by its capability of concurrently carrying out bucket work and crushing work, to which a crusher of a powerful crushing capacity can be attached.
A working device 2 is mounted on the upper turnable body 1b of the machine body 1 of the working machine. A blade 7 for removing earth is attached to be ascendable/descendible to a bracket 6 of the lower traveling body 1a of the machine body 1 via a blade arm 7a. A hydraulic cylinder 8 that moves the blade 7 in the upward and downward directions is attached to the bracket 6 and the blade 7. A crusher 9 is detachably attached to the blade 7. The crusher 9 is caused to crush an object to be crushed charged into a gap between a pair of rotors 10, 11 by rotating the pair of rotors 10, 11 by corresponding hydraulic motors. The hydraulic motors for driving the pair of rotors 10, 11 are driven by the oil pressure delivered by a hydraulic circuit for running the machine body 1.
