PROBLEM TO BE SOLVED: To smoothly steer a farm working machine with little shock having a pair of right and left crawler type running devices. SOLUTION: This steering device of a farm working machine is provided with a turning transmission means for speed reducing or braking one running device 1L and 1R where side clutches 20K and 20R are disconnected, whereby when steering is operated, first the side clutches 20L and 20R of one running device 1L and 1R are disconnected, subsequently by the operation in the same direction, the running device 1L and 1R where the side clutches 20L and 20R are disconnected and the turning transmission means are connected to interlock with each other through turning clutches 90L and 90R. In the device, the turning clutches 90L and 90R are formed as friction type clutches, the device is provided with a slipping low torque transmitting means for always transmitting low torque to the running devices 1L and 1R regardless of connection and disconnection of the side clutches 20L and 20R.
