PROBLEM TO BE SOLVED: To enable smooth turning motion of a sulky working vehicle to perform the turning motion by making the running speed of the right and left running parts to be different from each other. SOLUTION: This sulky working vehicle is provided with an engine E, a traveling speed changer 20 connected to the engine E and enabling the change of speed in plural stages in normal and reverse directions, a turning speed changer 23 connected to the engine E parallel to the traveling speed changer 20 and enabling stepless change of speed in normal and reverse directions by the operation of a steering operation part, a divided outputting mechanism 24 connected in interlocked state to the turning speed changer 23 in series and outputting the output of the turning speed changer 23 in a state divided into complementary two outputs and a right and left power synthesizing mechanism to synthesize the output of the running speed changer 20 and the normal and reverse output of the divided outputting mechanism 24 and transmitting the result to the right and left running parts. The output of the engine E is branched and transmitted to the running speed changer and the turning speed changer and the output of the running speed changer and the normal and reverse output of the divided outputting mechanism are synthesized by the right and left power synthesizing mechanism and transmitted to the right and left running parts. The running speeds of the right and left running parts are made to be different from each other by the operation of the steering operation part to perform the turning motion. A normal and reverse output switching mechanism 22 to switch the output direction in normal and reverse directions interlocked with the normal and reverse switching of the output direction of the running speed changer 20 is placed between the engine E and the turning speed changer 23.
