This engine stop solenoid is mounted on the cylinder head and controls fuel shutoff by retracting or extending its plunger to cut the fuel supply when the ignition is switched off. It is an electromechanical component that receives a signal from the ignition circuit; when energized, it holds the fuel system open, and when de-energized, it returns to the closed position, stopping the engine. A failing solenoid may cause the engine to fail to start, run on after the key is turned off, or shut down intermittently during operation. As an original AGCO part, the solenoid matches the original mounting geometry and electrical connector orientation, which ensures proper plunger travel and sealing against the cylinder head without modification. On installation, verify the plunger stroke aligns with the fuel shutoff lever and that the electrical connector is fully seated and free of corrosion.
