農機におけるＰＴＯクラツチ制御装置。 In a powered agricultural machine in which a hydraulic cylinder for engaging and disengaging a PTO clutch is controlled by a hydraulic switching valve for supplying and discharging pressure oil, the solenoid of the hydraulic switching valve can be switched into at least three states by controlling the electric circuit depending on whether or not the solenoid is energized. A single changeover switch is interposed, and this changeover switch is connected to a state where the solenoid is always energized, a state where the solenoid is de-energized, and an interlocking switch that is linked to the clutch petal that connects and disconnects the main clutch of the power agricultural machine. A PTO clutch control device for a power agricultural machine, which is configured to be selectively switchable between a state in which energization to a solenoid is cut off by pressing the button.
