Tractor pulling is a motor sport where modified farm tractors pull a metal sled along a course, with the winner being the tractor that pulls the sled the farthest distance. Competition tractors have powerful engines modified with parts from other motorsports, and must follow strict safety rules. The sport can be dangerous and loud, and spectators should take precautions.
Tractor pulling is a competitive motor sport in which modified farm tractors pull a metal sled along a prescribed course. The sled contains a large load of metal plates that are mechanically dragged forward as the sled moves along the course. Tractors pulling this ever-increasing load eventually lose forward momentum and torque, although a few might make it to the end of the range. The distance from start to finish is measured in hundredths of an inch (a few millimeters), and the tractor that pulls the sled the farthest distance is declared the winner. If more than one tractor reaches the end of the course, a second lap is done using heavier weights or a greater distance.
powerful engines
Competition level tractors may look like standard farm equipment, but the similarities stop at the basic body and tires. Tractor pulling is a power and torque based sport, which means the engine must be modified to make as much power as possible. Tractors in many competitions make 2,000-3,000 horsepower, and elite competitions may feature tractors capable of 10,000 horsepower or more. Some tractor pull enthusiasts have even been known to modify semi-trailer trucks for high-end competitions.
Competition tractor engines are often modified with parts intended for drag racing and other motorsports. Designers must be careful to balance power with safety, as these motors are designed to run to complete failure. Drivers must follow strict rules on staged tractor pulls, including the use of a roll bar and engine kill switches. If a driver falls off the tractor, the engine and fuel supply system must be automatically shut down immediately.
competition rules
During a tractor pull, the driver must keep his tractor within the posted limits. Touching any of the boundary lines results in disqualification. This is an important safety feature, as spectators may be seated in temporary stands close to the pitch. There are national and international tractor pulling associations that set guidelines for competitions and oversee local and regional chapters.
Strong and potentially dangerous
Some viewers find pulling the tractor difficult to watch. Numerous classifications of tractors must compete throughout the day, and winning efforts are not always apparent to those in the stands because the differences in distances can be so small. Racing tractor engines can also be extremely loud, so hearing protection is recommended for all bystanders, especially small children. Occasionally, an engine under extreme pressure will explode, sending dangerous shrapnel in all directions. No one except trained professionals should stand near these tractors during competitions.
