What Is A Tractor?

A tractor is a self-propelled power machine used to pull and drive working machinery to complete various mobile operations. It can also be used as a fixed working power. It consists of systems or devices such as engine, transmission, travel, steering, hydraulic suspension, power output, electrical instruments, driving control and traction. The engine power is transmitted to the drive wheel through the transmission system to make the tractor move. In real life, rubber belts are commonly used as the medium for power transmission. According to function and use, tractors are divided into agricultural, industrial and special purpose tractors; according to the structural type, they are divided into wheeled, crawler, boat-shaped tractors and self-propelled chassis.
