PROBLEM TO BE SOLVED: To perform steering as usual without causing a change of a steering feeling such as a traveling speed and a turning radius even in a low-temperature oil state such as the activation or the like of a working vehicle.SOLUTION: In the working vehicle, a turning hydraulic clutch (50) which changes a rotational speed difference between a turn-outside axle (16) and a turn-inside axle (16) at a turn of a machine body is arranged at a transmission path for transmitting a drive force from an engine to left and right axles (16), (16) of a traveling device, and when an oil temperature which is detected by an oil temperature sensor (67) for detecting an oil temperature in a transmission case (1) is low, the working pressure of the turning clutch (50) is boosted, and a rotational speed difference between the turn-outside axle (16) and the turn-inside axle (16) is increased.SELECTED DRAWING: Figure 5 |
