Once the box stops, the friction of the pan is the greatest and the pulling vehicle slows to a stop. The inside of the box contains lead blocks weighing a ton. The pan increases friction with the track as the box, which is chain driven, moves towards the front of the sled. The pan slides on the ground with little resistance at the start of the pull. Two major components of the sled are the box and the pan. As the competitor drives down the track, the load becomes increasingly heavier to pull. First, all competitions use what is called a motorized sled, or a "mechanical weight transfer device," which is hooked to their pulling vehicle by a chain. Most people have probably heard of truck and tractor pulls before, but really don't know the first thing about them. This modified tractor is just one participant in a series of truck and tractor pulls the county fair will feature tonight. The crowd jumps to its feet, cheering the competitor on. And with angry black exhaust escaping from its pipes like a cyclone, and a swirl of dust and debris surrounding it, 7,500 pounds of brightly painted aluminum, steel and rubber thunders past the stands. There is a murmur of voices as the crowd waits in anticipation, then suddenly, the ground begins to quake and the sound of a raging motor escalates. Spectators wait uncomfortably in their seats, mopping their brows with wrinkled, red bandanas. It's a sweltering, hot, summer night with no breeze, and even the light from the fireflies seems to make it hotter.
