Questions & Answers

Q: How does a tractor pull work?

Tractor pulls involve tractors pulling a sled set to the specifications for their class, with the winner being determined by the farthest distance pulled before getting stuck in the dirt.

Q: What is the purpose of the sled's weight box in a tractor pull?

The weight box is filled with weights that move towards the end of the sled, increasing resistance and making it harder for the tractor to pull, thereby testing its power and traction.

Q: How do tractor pull drivers control the balance of their tractors?

Tractor pull drivers use brakes and throttle control to maintain the balance of their tractors, adjusting weight distribution to achieve optimal traction and prevent wheelies or flip-overs.

Q: What role does the dirt play in a tractor pull?

The dirt acts as the surface on which the tractor's tires grip and shear. Properly shearing the dirt allows the tractor to maintain traction and maximize distance pulled.

Summary & Key Takeaways

• Tractor pulls are competitions where tractors pull a sled that is set to specific specifications based on different classes of tractors.

• The sled exerts friction on the dirt, and the farthest distance pulled determines the winner.

• Tractor pulls involve intricate physics, including the balancing of torque, weight distribution, and traction.
