PROBLEM TO BE SOLVED: To facilitate operation of a balk climbing arm of a mobile agricultural machine. SOLUTION: The rotatable balk climbing arm 63 capable of changing positions between a state of protrusively rotating forwardly downward and a stored state of rotating rearwardly upward is provided in a front part of a traveling body. A steering regulating tool 65 attached to the balk climbing arm 63 is arranged facing a pitman arm 64 operable by a steering wheel 5. In the stored state of rotating rearwardly upward of the balk climbing arm 63, the steering regulating tool 65 separates from the pitman arm 64, and in the state of protrusively rotating forwardly downward, the steering regulating tool 65 is moved near the pitman arm 64. Even when rotation and restoration of the balk climbing arm to a rear side and upward stored position is forgotten after traveling over a balk, the steering regulating tool 65 is moved in a separating side by a steering rotation of the pitman arm 64 by rotating the steering wheel 5 to the right and left while traveling, and an operator can restore the balk climbing arm 63 to the rear side and upward stored position without getting off the traveling body.
