<P>PROBLEM TO BE SOLVED: To eliminate complicated operation for various settings of an agricultural tractor. Ž<P>SOLUTION: A setting device (9) installed has a traveling position (P1) which sets the travelling mode of a travelling body to a 'two wheel drive' state and a utility machine lift control to an 'off' state and a plowing position (P4) which sets the travelling mode of the travelling body to a 'four wheel drive' state and the utility machine control to an 'on' state, and can select front wheel accelerating control, auto-lifting control or auto-brake control independently of each other. When the setting device (9) is operated to the plowing position (P4), the front wheel accelerating control, auto-lifting control or auto-brake control selected and set by the setting device (9) is compulsorily set to the On state, and, the 'four wheel drive' can be set in the state of keeping the work vehicle lift control to the Off state when the device is operated to the travelling position (P1).
