PROBLEM TO BE SOLVED: To provide a traveling vehicle such as a riding-type working machine enabling disturbance of a farm to be reduced by the rear wheel inside vehicle turning irrespective of conditions of farm field. SOLUTION: The traveling vehicle includes a controller 163 having the following: a control function (A1) functioning to consecutively turn on/off the drive of the rear wheel 11 inside vehicle turning in conjunction with steering mechanisms (e.g. 86I, 180, 217); a second control function (B1) functioning to intermittently turn on/off the drive of the rear wheel 11 inside vehicle turning; and an on/off control-selective function which, in turning the vehicle 2, conducts a processing of selecting the function (A1) or the function (B1) correspondingly to the depth of the farm field measured by a lift link sensor 48. Since the function (A1) or the function (B1) is selected matching to a condition of farm field, fine control over traveling/turning of the working vehicle corresponding to the depth of the farm field can be made.
