In a working vehicle, in response to the operation of an operating lever by an operator after idling stop of the engine, control is effected to automatically restart the engine in such a manner that the working vehicle will not unexpectedly move. After the idling stop (S4) of the engine, when a lock lever is brought to a lock position (S5, YES), a hydraulic circuit is controlled to cause the working vehicle to enter in its inoperable state in which the working vehicle will not move (S6). Thereafter, when a particular operation is applied to the operating lever (S7, YES), the engine (16) is restarted (S8). After restarting of the engine, only when all operating levers are in the neutral position (S9, YES), the lock lever is released from its locked state (S10, YES). Whereupon the hydraulic circuit is gradually restored to its normal operable state, the working vehicle can move (S11).
