[Scope of Claim for Utility Model Registration] (1) An electromagnetic proportional flow control valve in a hydraulic circuit that raises and lowers a working machine by switching the lifting control valve V to the raised, neutral, and lowered positions by rotating the position control lever 1. A is interposed between the hydraulic pump P and the hydraulic cylinder 6, and the electromagnetic proportional flow control valve A is connected to a vehicle speed sensor 2 that detects the rotation angle of the position control lever 1 and the traveling speed of the aircraft.
5. A work machine lifting control device for agricultural machinery, characterized in that the device is configured to change and control the degree of aperture using a value obtained by multiplying the detected values of step 5. (2) In the control device described in claim 1 of the utility model registration, during automatic tillage depth control, the rotation angle of the sensor 9 of the ground working machine and the vehicle speed sensor 2 are controlled.
5. A work machine lifting control device for agricultural machinery, characterized in that an electromagnetic proportional flow control valve A is configured to change and control its throttle degree based on a value obtained by synergizing the detected values of 5.
