To prevent deterioration of a hose for discharging cooling water of an engine 9 and a radiator 50 and also facilitate discharge work.
The radiator 50 is provided in a rear part of the engine 9 mounted to a front part of a traveling body 1, and a middle part of the discharge hose 65 with one end connected to the radiator 50 is arranged along an inner face of a body frame 3. Due to this structure, external force from the outer side of the traveling body 1 is not directly applied to the discharge hose 65. Since the middle part of the discharge hose 65 is fixed via a clamp 69, swing in the middle of the discharge hose 65 is prevented and deterioration (fatigue breakdown) of the hose 65 caused by repeated bending etc. is extremely reduced. A drain plug 70 connected to the front end part of the discharge hose 65 is arranged in the vicinity of the front end of the traveling body 1, and a hose 67 for discharging engine cooling water is connected to the middle part of the discharge hose 65. Due to this structure, liquid inside the engine 9 and the radiator 50 can be easily and promptly discharged only by operating the one drain plug 70.
