<P>PROBLEM TO BE SOLVED: To provide a working vehicle capable of switching from a four-wheel drive state to a two-wheel drive state during a halt of an engine and improving maintainability by eliminating a load to the wheel during maintaining a rear wheel. <P>SOLUTION: The working vehicle is provided with a standard hydraulic clutch S for driving a front wheel 2 at a speed substantially equal to the driving speed of the rear wheel 3 and a speed increasing hydraulic clutch B for driving the front wheel 2 at the larger speed than the driving speed of the rear wheel 3. The standard clutch S is provided with a biasing member 33 and the standard clutch S is turned on so as to make the drive mode shift into the four-wheel drive state by the biasing member 33 when the engine is stopped and the pressurized oil is not supplied to the hydraulic clutches S, B. Meanwhile, the working vehicle is provided with a two-wheel drive/four-wheel drive switching mechanism A for switching from the four-wheel drive state to the two-wheel drive state during the halt of the engine. <P>COPYRIGHT: (C)2012,JPO&INPIT |
