PROBLEM TO BE SOLVED: To provide a traveling device having a steering mechanism capable of adequately adjusting the braking pressure of a turning clutch during the traveling in a standard mode and the braking pressure of the turning clutch during the traveling in a wet paddy mode. SOLUTION: As shown in Fig. 4, in the traveling device during the traveling in a wet paddy mode (in which the number of rotation of a traveling drive body 3 on the inner turning side during the turn is higher than the set value in the standard mode), and/or during the traveling in the standard mode (in which the number of rotation of the traveling drive body 3 on the inner turning side during the turn is set to be zero or substantially zero), the braking pressure of the traveling drive bodies on the inner turning side and the outer turning side is respectively controlled, and the braking pressure of a turning clutch 82 in the standard mode is used when the threshing clutch is coupled. When the threshing clutch is uncoupled, the traveling steerability of a combine is improved by controlling the braking pressure by using the braking pressure of the turning clutch 82 in the standard mode. In addition, any defective turn can be avoided, and the safety is improved even when the change to the standard mode when traveling on the road is forgotten, or adjustment of the braking pressure in the wet paddy mode is forgotten.
