御装置。 In a paddy field work machine configured to control the elevation movement of the working part by switching control valves by operating the elevation control lever, in the operating system from the elevation control lever to the control valve, there is a control valve for each control position of the elevation control lever. A valve actuating body is provided which switches the control valve in conjunction with the operation of the lift control lever, and the lift control lever is locked in a locking part provided at a fixed position of the lever guide between the valve actuating body and the lift control lever. In order to avoid this problem, a bullet is installed that biases the lift control lever to the side, but the bullet has tension on the operating side of the lift control lever to the fixed position, so that the control valve faces the fixed state side. Lifting and lowering control of a working part in a paddy field work machine, characterized in that a flexible mechanism part is formed that energizes and relaxes on the operating side of the lift control lever to the automatic position so as not to act on the control valve. Device.
