  16. Rear wheel weights and wheel bolts cannot extend more than 5 inches past the rear tires and bolts have protection.

  17. Weights must not extend rearward beyond the rear most portion of the rear tires.  For those tractors with factory components (ie.  platform, fuel tanks, etc.) that prohibit the placement of the weights on the rear of the tractor, weights may be attached such that they extend past the rear tires, but must be forward of wheelie bar bumpers (bumpers are required for this rule in any division.)

  18. Any part falling off the tractor after being hooked and until the tractor is unhooked will result in disqualification.

  19. Gasoline, diesel, or LP fuels only.  NO Nitrous Oxide is to be used.

  21. Protest may be filed against a puller, but only by other pullers in the same class.  The protest must be filed with the event director before the protested tractor exits the pull area.  The protestor or protestors must also submit their tractor for inspection as well.  A $100 protest fee will be submitted with protest to the event director.  The protest fee will be returned to protestor if contested tractor is found to be in violation.  However, if contested tractor is found not in violation, contested tractor will receive the protest fee.  However, if BOTH tractors are found in violation, the protest fee is donated to the association and BOTH tractors are disqualified.
