Although tractors are relatively complicated machines, their types and sizes are also different, but they are composed of three parts: engine, chassis and electrical equipment, each of which is indispensable.
Engine
It is a device for the tractor to generate power, and its function is to convert the thermal energy of the fuel into mechanical energy to output power. Most agricultural tractors produced in my country use diesel engines.
Chassis
It is the power transmission device of the tractor. Its function is to transmit the power of the engine to the driving wheels and the working device to make the tractor travel and complete the mobile operation or the fixed function. This function is realized through the cooperation and coordination of the transmission system, the walking system, the steering system, the braking system and the working device. At the same time, they constitute the frame and body of the tractor. Therefore, we collectively refer to the four systems and one device mentioned above as the chassis. In other words, in the entire tractor, all other systems and devices except the engine and electrical equipment are collectively referred to as the tractor chassis.
Electrical Equipment
It is a device to ensure that the tractor uses electricity. Its role is to solve lighting, safety signals and engine starting.
