A tractor's engine is managed and controlled by an electronic control device known as a tractor ECU, or engine control unit. It makes performance modifications to the engine based on data from sensors that track a variety of engine parameters, including temperature, speed, fuel level, and exhaust pollutants.

The tractor ECU is in charge of managing a number of engine systems, including the amount of air injected into the engine and the timing of ignition. It makes use of algorithms and programming to adjust the engine's performance for numerous factors, including varied types of terrain and weather.

The efficiency of the tractor is increased, fuel consumption is decreased, and harmful emissions are decreased when a tractor ECU is used. Additionally, it offers diagnostic features that let mechanics
