The powerpull challenge is a true head-to-head competition. Each team must build a powerpuller, weighing up to 1 ton, which will be chained to each other. The teams will then compete in a tug of war (best 2 out of 3) to determine victory.

Before we get to the show, a quick powerpuller lesson. A powerpuller is, more or less, a tractor that produces an enormous amount of horsepower that will pull a sled, weighted down with concrete blocks. The big tires at the rear are for traction and the small tires at the front...well...aren't much good for anything since they're in the air most of the time. Steering, if needed can be accomplished by braking one of the rear tires. Gently.
