A walking tractor is a small tractor, a means of transport and agricultural machinery popular in Chinese towns and villages. It is powered by a diesel engine. Its small size, flexibility and powerful power make it very popular among farmers. The walking tractor can travel by relying on the power of the internal combustion engine through the transmission system. The driving wheel that obtains the driving torque then exerts a small, backward horizontal force (tangential force) on the ground through the tire pattern and tire surface. This reaction force is the driving force (also called positional propulsion) that pushes the tractor forward. It has a simple structure and low power, and is suitable for small plots of cultivated land. The driver holds the handrail to control the operating mechanism, pull or drive the matching agricultural implements to operate.
