おける作業部の昇降制御装置。 Paddy field work that is equipped with an automatic switching mechanism that is configured to move to a working position in conjunction with the depression of a control pedal and automatically switch the lifting control mechanism that controls the lifting and lowering movement of the working part from an automatic state to a raised state. In the machine, the automatic switching mechanism is provided with a return mechanism that returns the automatic switching mechanism to a non-working position when the working part rises to a predetermined height, and the lifting control mechanism is provided with a return mechanism that causes the working part to rise to the highest position. A second automatic switching mechanism is provided to automatically switch the elevation control mechanism from the raised state to the fixed state approximately in time with the completion of the return of the automatic switching mechanism to the non-operating position a little earlier, and The second automatic switching mechanism is configured using a pressing body provided on the elevating link mechanism side that controls the elevating movement of the working part, and an actuating body provided on the elevating control mechanism side, and the working part is connected to the automatic switching mechanism. When the return to posture is almost complete,
1. A lifting control device for a working part of a paddy field working machine, characterized in that the pressing body is configured to switch a star-fall control mechanism from a rising state to a fixed state by pressing and contacting an operating body.
