PULLING CONTEST PROCEDURES

1. Entry: Upon arrival at the pull site, pullers shall go immediately to the registration office and enter all the classes that the vehicle will participate in.
2. Once a competitor has registered they shall return to their vehicle and remain there until the vehicle is teched by a USA-East Official.
3. Officials will place a “NOT TECH INSPECTED” tag on the vehicle if no one is at the competition vehicle during the tech process. It is then strictly the Competitor’ responsibility to make sure that their vehicle is properly tech inspected before it comes to the track to compete.
4. On any vehicle competing in a class requiring a safety shutdown switch the driver is responsible for installing the tie strap to the safety switch.
5. If a competitor feels that a sled malfunction has occurred with the vehicle's safety switch, the competitor must alert the finish flagman of that fact. The driver of the vehicle will then move the pulling vehicle off the pulling track to a designated area by the track official. The vehicle must be shut down and safely parked. Then the vehicle will be inspected by an USA-East Official and driver. If the Official feels there is a malfunction of the safety switch then the vehicle will be allowed a re-hook. If the competitor moves the vehicle from the pulling track and does not alert the finish flagman that there may have been a problem the competitor may not return for another hook.
6. Vehicles may enter more than one class, but may enter only once in each class.
7. Events are ‘open to the world’ – NO memberships are required to enter. (Certain events may have exceptions…Check with the Full Pull Office 412-480-9307)
8. Participants must be a member of USA-EAST in order to collect points, and competitors may join at any USA-EAST event.  Membership must be in place prior to hooking to the sled in order to collect points.
9. All Competitors must be registered at least one hour prior to the pull.
10. Pulling order will be determined by ‘luck of the draw’ at sign-in.  Numbers used may not be visible to the pullers.  When a team has two or more entries in a single class, the vehicles must be registered separately so as to prevent the misplacing of the tractors numerically.
11. Should a Competitor be forced to withdraw from a class due to breakage from a previous class, the competitor must notify officials before class begins to receive a refund. Entry money will not be refunded if the competitor does not scratch before the class starts.
12. Once a Competitor has hooked to the sled, he will not be refunded entry fee money.
13. If puller arrives late (after the class has started) the competitor may NOT compete in the class.
14. The only approved late entries accepted will be those pullers who have made prior arrangements with the registration official prior to arriving.
15. Competitors will earn NO points if entry fee is refunded.  This also applies to rain-out situations.
16. Pulling vehicles may be held for post competition tech inspection. Failure to abide may result in a DQ.

CONTEST PROCEDURE

1. Any puller under 18 must have written consent from a parent or guardian and prior approval by the USA-EAST executive committee and their insurance carrier.
2. Contestants may be barred from pulling due to emotional or physical reasons. Ex: drinking, illness, etc.

8. Any driver or crew member found under the influence of drugs or using intoxicating agents in the track area will be disqualified. Track area is defined as 35 feet surrounding the track
9. No videotaping is allowed closer than 35 feet from track or in a designated area approved by officials.
10. A driver’s meeting is optional and may or may not be held before the pull starts.
11. The first puller in the class will be considered the ‘Test Puller’.   This ‘Test Puller’ may accept their pull distance, or choose to come back immediately or drop to ANY position in the pulling order.
12. Should the head official rule that the first puller did not make an honest attempt, the next puller in line will become the ‘test puller’ and will have all of the options available to the ‘test puller’.  This process may be continued (at the option of the head official) until the class is set.
13. The finish flag official must be informed of the ‘Test Puller’s’ decision before leaving the track. No other contestant will be given the option of test Competitor.  
14. A pulling vehicle may drop to any position in the class due to mechanical breakage. This will count as the first of two attempts for the vehicle to make a measurable distance. This dropping must be approved by the track judge.  Safety equipment does not qualify for a mechanical problem.
15. A competitor has three minutes to hook to the sled after track is ready or if after competition director and/or head flag calls them to the sled. Failure to do so will result in DQ with no refund of entry. (Competitors have Three (3) Minutes to come to track and make an attempt.  If they do not make a measurable pull then they will have the option of trying immediately or dropping. This will count as one attempt.)
16. Competitors may spot the sled anywhere in bounds and behind the starting line if they wish. A cone will be provided for this purpose.  This must be done while sled is returning to the starting line. Only one sled spotting is allowed.  Once the sled has returned to the starting line and is ready the puller may NOT re-spot the sled.  Doing so will count as the pullers ‘first attempt’.
17. All pulls will start with a tight chain.  No jerking of the sled. Excessive sled jerking may cause DQ.
18. Excessive loss of liquid will result in disqualification, if the vehicle is under the green flag. If a vehicle is flagged, pull will be measured from the point of the red flag being issued. Failure to stop will be cause for disqualification. Excessive is defined as any steady or intermittent steam equal to a spot on the track of eight (8) inches in diameter.
19. Pulling will be over when forward motion stops. Competitors must stop immediately when RED flagged.
20. When there is a re-pull caused by a contest malfunction, the puller or pullers affected may drop to ANY position in the class or may pull again immediately.  Competitors may not move any weight.
21. All pulls will be measured to the nearest 1/100 foot utilizing an Agritronic GPS sled measuring system or Laser measuring device.
22. When possible, all contestants must drive on and off the track. Tow starting will be done as a last resort and under track judge’s discretion
23. USA-EAST reserves the right to interpret any and all rules that are in force. Adoption of new rules could become necessary to promote safety or to benefit the sport.
24. Competition Director decisions are final and unappealable on any point of controversy.  Disagreement leading to arguments can result in disqualification.
25. Any Competitors abusing an official or other USA-EAST personal both verbally and/or physically, will be disqualified for that event and will be asked to leave.
26. All pulling vehicles must pass a tech inspection and meet all safety requirements before they can pull at any event. USA-EAST reserves the right to fully inspect any vehicle at any time.  Refusal to submit to a complete tech inspection will result in disqualification of the vehicle.
27. All competition vehicles must report to the scales full of fuel/water/ice, etc.  Fuel/water/ice, etc. may not be added once the pulling vehicle has been weighed.
28. Once a vehicle has made its measurable pull and is unhooked from the sled it must be moved from the end of the pulling track. Vehicles cannot be parked where they may interfere with the laser measuring device or flow of event traffic.
29. Any disqualification on the first attempt bars a second attempt unless the class is restarted.  
30. The “Test Hook” puller may come back if they go out of bounds on their test hook attempt.
31. Pullers disqualified for actions on the track may still receive purse money.  Should the class not be full a disqualified puller shall receive last place purse money IF the vehicle has made a measured pull.

FLOATING FINISH LINE

1. Floating Finish Lines will be utilized at all events for all classes unless the head tech official determines that a pull off system will be used.  If a pull off is to be used for a certain class it will be announced prior to the class starting.
2. Boundary line will be 320’ long to start the pull, even though a Full Pull may only be 300’. Competitors may not touch boundary lines at any time. The Full Pull line will be established by the Head Track Official no less than 300 feet and no later than the fifth competitor, after a sled reset. The Full Pull line can be set in front of a vehicle even if the vehicle has gone past 300 feet at either 310, 320. White disqualification line(s) will be 320 feet for the entire contest. If Head Track Official determines a floating finish is need
