全装置。 A switching means inserted between the key switch and the electric circuit that controls the engine includes a neutral position detector that detects the neutral position of the shift lever in the automatic transmission, and a seating detector that detects the seating state of the driver. A circuit is connected in series with a drawbar detector that detects the operating state of the operating lever in the coupler in parallel, and switching is performed as long as a detection signal is output from any one of the detectors. A safety device for a towing tractor having an automatic transmission configured to hold a switching means in an on state and switch the switching means off when no detection signal is output.
