A power generator includes a supporting frame, a generator supported by the supporting frame, and an engine mechanism including an engine driving the generator and a recoil starter for starting the engine via starter cable. The power generator further includes a hand-free starter arrangement which includes a foot pedal movably supported by the supporting frame and a transmission unit coupling a pulling end of the starter cable with the foot pedal to transmit the downward stepping force of the foot pedal to a pulling force of the starter cable. A downward displacement of the foot pedal is corresponding to an operation length of the starter cable to start the engine such that when the foot pedal is depressed, the starter cable is pulled with the operation length to start the engine in a hand-free manner.
