PURPOSE: A hybrid working machine using PTO(power take off) is provided to adjust work load by moving the working machine up and down. CONSTITUTION: A hybrid working machine using PTO(power take off) comprises a generator motor(10), an electric motor(20), a hydraulic pump(30), a three-point hitch hydraulic cylinder(40), a displacement sensor(42), a speed sensor(44), and a controller(50). The generator motor is connected to a PTO shaft of a tractor working machine and maintains the torque and RPM of the PTO shaft. The electric motor generates mechanical energy. The hydraulic pump is connected to the electric motor and generates hydraulic pressure. The three-point hitch hydraulic cylinder ascends or descends a working machine through the pressure provided by the hydraulic pump. |
