Although tractors are a relatively complex machine with different types and sizes, they are all composed of three main parts: engine, chassis, and electrical equipment, each of which is indispensable.

Engine

It is a device for tractors to generate power, and its function is to convert the thermal energy of fuel into mechanical energy to output power externally. Most agricultural tractors produced in our country use diesel engines.

Chassis

It is a device for tractors to transmit power. Its function is to transfer the power of the engine to the driving wheels and working devices to drive the tractor, and to complete the mobile operation or fixing function. This function is achieved through the mutual cooperation and coordination of the transmission system, walking system, steering system, braking system, and working device, which also constitute the framework and body of the tractor. Therefore, we collectively refer to the four major systems and one major device mentioned above as the chassis. That is to say, all other systems and devices in the tractor, except for the engine and electrical equipment, are collectively referred to as the tractor chassis.

Electrical equipment

It is a device that ensures the electricity consumption of the tractor. Its function is to solve lighting, safety signals, and engine starting.
