This patent describes an engine shut-off system particularly adapted for use in conjunction with a propulsion engine for an off-highway vehicle such as a large dumper truck and the like. It comprises: a supply conduit for supplying fuel to the engine and in communication with a source of fluid fuel; fuel flow shut-off valve means interposed in the conduit, the shut-off valve means being normally biased to a closed position and being actuated to an open position by valve actuating means; actuator means operable to be engaged with the valve actuating means and a source of pressure fluid for placing the shut-off valve means in an operating condition which will rapidly close the shut-off valve means; and a source of pressure fluid disposed for operating from at least one of an operator's cab for the vehicle and a position in proximity to the ground surface and exterior of the vehicle for operation of the actuator means to cause the shut-off valve means to shut off fuel flow to the engine.
