An internal combustion engine shutdown device is disclosed. The device stops an engine running at high speed in a controlled fashion when a condition arises in a peripheral device or apparatus being driven or operated by the engine. The device provides a relay, a fuel shutoff control, an engine throttle control, and a timer. Upon the receipt of an external signal such as the de-energizing of a conventional “kill switch”, the device immediately reduces engine speed to idle by the throttle control and delays the stopping of the engine by the timer until a pre-set time period has passed. Once the time period has elapsed so that the engine is in the proper state to be stopped, the fuel to the engine is cut off by the fuel shutoff control. The device is particularly adapted to the operation of an internal combustion engine used in a center pivot irrigation system.

An internal combustion engine shutdown device for the controlled stopping of an internal combustion engine upon the receipt of a signal, the engine of the type having an ignition system, a fuel supply in fluid communication with the engine and an engine speed control; the device comprising: a relay means for relaying the signal; a timing means for determining a pre-set time period; a throttle control means for controlling said engine speed control; and an engine stopping means for stopping the engine wherein said relay means is operably connected to said timing means and to said throttle control means and wherein said timing means is operably connected to said engine stopping means and wherein said throttle control means is operably connected to said engine speed control. A method for the controlled stopping of an internal combustion engine upon the receipt of a signal, the engine of the type having a fuel supply in fluid communication with the engine and an engine speed control; the method comprising the steps of: providing a relay means for relaying the signal; a timing means for determining a pre-set time period; a throttle control means for controlling said engine speed control; and an engine stopping means for stopping the engine wherein said relay means is operably connected to said timing means and to said throttle control means and wherein said timing means is operably connected to said engine stopping means and wherein said throttle control means is operably connected to said engine speed control; relaying the signal by the relay means to the timing means to start the timing means; relaying the signal to the throttle control means to reduce the engine speed by slowing said engine speed control; delaying a pre-set period of time by use of the timing means; and stopping the engine by activating said engine stopping means.
