PROBLEM TO BE SOLVED: To provide a travelling vehicle such as a combine which can be operated (steered) with a feel of operation similar to that of a four-wheel automobile, wherein a mechanism is simplified for linking and connecting a main shift lever and a steering handle to straight moving and turning HST mechanisms. SOLUTION: The travelling vehicle comprises a controller 131 turnable around two axes P, S perpendicular to each other. The controller 131 operates the turning HST mechanism with normal/reverse turn around the vertical axis P following the operation of the steering handle, and operates the straight moving HST mechanism with normal/reverse turn around the horizontal axis S following the operation of the main shift lever. An axis AX2 of an turning output shaft 164 for converting the turning amount of the controller 131 around the vertical axis P into the controlled variable of the turning HST mechanism and the axis of an intermediate shaft 155 for converting the turning amount of the controller 131 around the horizontal axis S into the controlled variable of the straight moving HST mechanism are located substantially on the same plane.
