The main function of the fuel cut-off valve of the lawn mower is to cut off the fuel supply in emergency situations, in order to prevent dangerous situations such as fires and explosions caused by fuel leaks, thereby protecting the safety of the engine and the lawn mower as a whole. The fuel cut-off valve is usually composed of a mechanical structure and an electronic control structure. When the lawn mower collides or in other emergency situations, the electronic control unit send a signal.
