Ever been to a Tractor pull? No? Then get ready for ground shaking, noise filled none stop action. These souped up tractors pulling a weight sleigh are very exciting to see in action. The weight sleigh has a large weight concentrated at the rear of the sleigh at the begaining of the pull. As the pull gets underway, the weight is driven forward by a chain being driven by wheels on the sleigh until the weight is all concentrated at the front of the sleigh.The Tractor has to try and overcome this while trying to cross the finish line. This particular tractor was running a 1500 horsepower gas turbine engine.
