Derby Rules

• Hitting the sides is not allowed unless it is in the area directly in front of the cage.
• Front and rear hitting is preferred. At any time a driver touches the ground, they are done.
• If any mower lands on its side, all drivers MUST STOP!! We will set the mowers back up, and if the mower restarts, they can resume the derby.
• Numbers must be on the hood.
• Remember, this is for fun. We don't want anyone hurt.
