PROBLEM TO BE SOLVED: To provide a small tractor which has a front wheel speed increaser and a position type hydraulic control mechanism, is inexpensive, and can usually easily be checked. SOLUTION: This tractor having the front wheel speed increaser 8 in a front wheel-driving system is characterized by disposing an electric motor 45 on the side of a transmission case 6 for receiving a transmission, normally or inversely rotating the electric motor 45 in interlock with the operation of a steering handle 7 to switch the front wheel speed increaser 8 into a standard four-driving state or a front wheel speed-increasing state, disposing a plate 122 on the rear upper portion of the transmission case 6, disposing another electric motor 130 for automatically lifting an implement in interlock with the operation of a steering handle 7 on the plate 122, and further disposing a lifting control valve 131, a deceleration valve 132, and a relief valve 134, and the like.
