Though many would consider NASCAR to be the stereotypical motorsport of the southern United States, the residents of Green County in Kentucky have a different opinion. For them, the only event which harnesses the power of hot-engines, roaring exhaust pipes, and good-hearted competition is tractor pulling. Born from the boasts of proud farmers, tractor pulling began as rural contests of strength between two teams of workhorses. However, with the invention of the tractor in 1929, motorized vehicles were soon put to use. Today, the sport sees competitions all around the world with multiple divisions in each gathering. Despite the speed shown in NASCAR, tractor pulling maintains its reputation as the most powerful motorsport, due to the use of modified, multi-engine tractors.
