PROBLEM: To provide a working vehicle traveling by an operation, the operation chosen by operators from either an oil-pressured pilot operation which drives a traveling device based on an operation of an oil-pressured pilot controller to activate a pilot valve or an electric operation which drives the traveling device based on an operation of an electric control device to output electric signal. SOLUTION: In an operation for traveling a working vehicle, it is provided that an operation selection switch 26 to choose either an oil-pressured pilot operation or an electric operation, a control device 23 to input an electric signal for traveling transmitted from an electric operation device and a selection signal from the operation selection switch, the third electro-magnetic valve 44 to forbid outputting pilot pressure from a pilot valve for traveling to a control valve for traveling based on a control signal from the control device, the first to the fourth electro-magnetic proportional valve 48 to 51 to output a pilot pressure to the control valve for traveling based on the control signal from the control device and the first to the fourth shuttle valve 38 to 41 to lead the output pilot pressure to the control valve for traveling. |
