置。[Scope of Claim for Utility Model Registration] In lifting and lowering devices for mobile agricultural machines such as rice transplanters and flooded direct sowing machines, which move the wheels and the machine body vertically relative to each other by expanding and contracting the cylinder by operating the lift control lever, neutralization of the cylinder and A control shaft for controlling extension and contraction is rotatably provided on the cylinder control device, a lever is fixed to the control shaft, and an arm is fitted around the lever and is rotatable relative to the lever over a predetermined angular range. , a spring is interposed between the arm and the lever to urge them to rotate in opposite directions, the arm is connected to a lift operation lever, and the lever is returned to the neutral position by movement of the cylinder. The clutch is connected to the side by an interlocking means, and the interlocking means is interposed with a clutch that turns on and off the interlocking state, and a connecting wire and A lock lever is provided which is interlocked and connected via the connecting plate and which removably engages with the connecting plate to prevent movement of the connecting plate, and when the lock lever prevents the connecting plate from moving, the lift operation lever is activated. 1. An elevating device for a mobile agricultural machine, characterized in that a long hole for allowing movement is provided at a joint between a connecting plate and an elevating operation lever.
