ていることを特徴とする移動農機の昇降装置。[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 relative to each other up and down 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 for turning on and off the interlocking state, and the clutch and the lifting operation lever are interlocked and connected so that the clutch is in the "on" position when the operation lever is in the raised position. A lifting device for mobile agricultural machinery, characterized by:
