Here, the PTO operation signal may be an operation signal indicating the power transmission to each configuration of the specially equipped vehicle. In this case, each of the components means a switch in which electric power is transmitted. For example, a horizontal automatic switch, a turn-on automatic switch, a PTO automatic switch, a reverse automatic switch, a start switch, a PTO switch, a one- Up switch, an external hydraulic manual down switch, and the like. The operation control unit controls the operation function and generates a PTO operation signal. The electric control unit controls electricity. The electric control unit checks the operation signal transmitted from the operation control unit and transmits electricity to the solenoid valve to control on / off of the solenoid valve. When the solenoid valve is on, the electric control unit operates to transmit hydraulic pressure or air through the PTO. Here, the electric control unit may be an electric distribution board.

The user terminal 200 communicates with the PTO controller 100 and the management server 300. The user terminal 200 monitors status information on the power transmission of the specially equipped vehicle using the PTO operation signal of the specially equipped vehicle received from the PTO controller 100.
