Claims

[Scope of utility model registration request]

In a structure in which horizontal control of the aircraft is performed by appropriately varying the support height of the aircraft using a lifting cylinder interposed between the traveling section and the aircraft, the lowest limit is used to detect the position just before the lowest limit of the aircraft support height. In addition to providing a sensor, a mechanical stopper for regulating the position of the body support height in the lower limit direction is provided within the lowest limit detection operation range of the lowest limit sensor, and the lowest limit position of the body support height is detected by the lowest limit sensor. 1. A horizontal control device for an agricultural working machine, characterized in that the horizontal control device for an agricultural working machine is configured to stop the operation of the lifting cylinder on the lower limit side of the machine body support height after a predetermined period of time has elapsed.
