るローリング制御機構。 In the paddy field work machine configured to perform rolling control of the machine body by swinging the balance arms connected to the left and right running wheels by hydraulic switching operation of the rolling control cylinder based on the detection of the left and right inclination of the machine body, A relief valve that can be switched between an open state and a closed state is provided in the oil passage from the switching valve that performs hydraulic pressure switching operation of the rolling control cylinder to the rolling control cylinder, and the relief valve is
A lock operating tool for swinging and locking the balance arm is interlocked and connected so as to switch from a closed state to an open state when the lock operating tool is operated to a locked state,
The rolling control cylinder is configured to be in communication with the relief valve which is opened in conjunction with the operation of the lock operating tool to the locked state, so that the rolling control cylinder can freely operate. A rolling control mechanism for paddy field work equipment featuring:
