In a working vehicle (1) which includes left and right traveling devices (2L, 2R), a pair of hydraulic traveling motors (13, 14) are installed to drive the respective traveling devices (2L, 2R), and a pair of hydraulic directional control valves (15, 16) are provided for the respective hydraulic traveling motors (13, 14) in order to control the traveling of the vehicle. A throttle valve (55) is provided in a pilot oil-passage (54), and connected to a drain oil-passage (30) after passing serially through the pair of hydraulic directional control valves (15, 16) below the throttle valve (55). A pressure switch (61) for warning the traveling state is operated by a pilot hydraulic pressure which is pressure of oil within an oil-passage between the throttle valve (55) and an upstream one of the left and right hydraulic directional control valves (15, 16). <IMAGE> |
