タリ制御回路。゛A rotary control circuit in which a directional switching valve that controls the main cylinder and an electromagnetic switching valve that controls horizontal control of the rotary via an auxiliary cylinder are connected to a hydraulic pump via a flow divider that gives priority to the auxiliary cylinder side. In this case, the solenoid switching valve is a six-way switching valve, and the outlet of its center bypass passage and the pump port of the directional switching valve are connected via a check valve that allows fluid flow only toward the directional switching valve side, and when the auxiliary cylinder is driven, A rotary control circuit for agricultural machinery, characterized in that the return liquid is returned to a tank via an electromagnetic switching valve.
