The history of tractors dates back to the late 19th century, with the first internal combustion engine tractors emerging around the 1890s. Prior to this innovation, farmers relied on animal power and manual labor to till the land and harvest crops. While horses and oxen were effective domesticated animals, their labor-intensive management and slower work rates limited agricultural productivity. The introduction of tractors marked a significant turning point in farming, allowing for mechanized operations that vastly outperformed traditional methods.

With the continuous evolution of automotive engineering, cam technology has advanced significantly. Variable valve timing (VVT) systems, such as VTEC (Variable Valve Timing and Lift Electronic Control) developed by Honda or BMW’s Vanos, has transformed the way engine cams operate. By adjusting the timing of the valves based on engine speed and load, VVT allows for a more adaptable engine that delivers both efficiency and performance.
