PURPOSE:To prevent an improper control attitude due to erroneous detection by a gravity system detector, by a method wherein, in a working vehicle for controlling an attitude to ground of a vehicle, a control mechanism is brought to an inactive state by a given set time from a time when the vehicle starts or stops running. CONSTITUTION:Even if a running ground is uneven, based on a detecting result of a detector 12, cylinders C1, C2 and C3 of two front wheels and one of two rear wheels are automatically controlled by a control mechanism 13 on a basis of the other rear wheel so that a first detector 12 is brought to a horizontal or an approximately horizontal detecting state. Additionally, even if a vehicle is accelerated or decelerated owing to start or stop, and as a result, the detector 12 is brought to an erroneous detecting state resulting from the swing of a weight 9 due to innertia, a self-operating device 23 actuates through the working of a second detector 19 which detects that the vehicle has performed a start or a stop operation, and the control mechanism 13 is controlled into a non-operating state by a full set time during which the weight 9 restores to a steady state. |
