PROBLEM TO BE SOLVED: To solve a problem of causing a high cost and making a mistake of setting operation for respectively independently providing an on/off setter for both control devices, in a tractor sometimes provided with the brake control device applying a rear wheel brake in a turn inner side associated with turn operation and the front wheel accelerating device increasing a peripheral speed of a front wheel higher than a rear wheel. SOLUTION: A setter for on/off switching operation of both the control devices is constituted by a single dial type setter 4, a setting position of this dial type setter 4 is constituted by arranging a brake force [strong] side of [brake control on] position next to an [off] position making inoperative operation of both the brake control device and front wheel accelerating control device so as to change the setting position, as it separates from the [off] position, gradually to a brake force [weak] side, in addition [front wheel accelerating control device on] is arranged next to the brake force [weak] side.
