When you turn the key in your Kubota tractor, you expect the engine to start. But if your engine is having trouble starting, it could be a problem with the glow plugs. Glow plugs are responsible for heating the combustion chamber and helping the engine start, and if they’re not functioning properly, your engine may not start or it may take longer than usual to start. In this article, we’ll take a closer look at your Kubota glow plug wiring diagram and explain how it works.
What are glow plugs?
Glow plugs are small devices that heat the combustion chamber in a diesel engine so that it can start more easily. When you turn the key in your Kubota tractor’s ignition, the glow plug controller sends an electrical current to the glow plugs. This current causes them to heat up and provide the necessary heat to ignite the fuel in the engine.
Glow plugs are made up of a heating element and a tip. The heating element is made of a special material that can withstand the high temperatures of the combustion chamber. The tip is usually made of a durable metal that can withstand the intense heat and pressure of the combustion process.
