PROBLEM TO BE SOLVED: To avoid occurrence of forgetting about operation and maloperation of an operation lever by using the single operation lever, and to diversify driving form of a PTO clutch with a differential gear. SOLUTION: The differential gear is installed in a transmission mechanism of a traveling system, and the PTO clutch for connecting and disconnecting the power transmission to the working apparatus side is provided in the transmission mechanism of a working system. Furthermore, the single operation lever 4 for linking to the differential gear and PTO clutch is configured to perform changeover operation to a working position s3 for performing ON operation of the PTO clutch in a differential locking state, a non-working traveling position s1 for performing OFF operation of the PTO clutch in a released state of differential locking, and a differential locking non-working position s2 for performing the OFF operation of the PTO clutch in the differential locking state can be performed.
