PROBLEM TO BE SOLVED: To enhance turning performance by preventing slipping of wheels in a farm working vehicle having four or more driving wheels. SOLUTION: A running portion 2 is disposed to a vehicle body and has at least two pairs of right and left driving wheels 33, 34, 35. Peripheral velocity difference is made between the right driving wheels 33, 34, 35 and the left driving wheels 33, 34, 35, respectively so that the vehicle can turn. When the turning, the peripheral velocity of the driving wheels apart from the center of gravity of vehicle body is higher than that of the driving wheels near the center of gravity of vehicle body.
