TRACK RULES

1. Vehicles may be entered in as many classes as 3 per session, but only once in each class. Vehicles may enter only two primary classes, the third class must be an outlaw class.

2. Pullers must be registered in ½ hour before the scheduled start time of the pull. Late entries may be charged $5.00 extra unless breakdown is proven.

3. Tractors are not allowed to line up and scale until the class prior to that tractor's class has started. The first class will line up and scale approx 15 min prior to the pull start time. Exceptions will be made for track workers and sled operators.

4. There will be a driver’s meeting ½ hour before the start of the pull, at the scale.

5. Vehicles should be ready by the time the sled arrives back to the starting position. Pullers will have only 3 minutes after the sled is back in place and the leveling equipment is off the track to start their pull.  If they are unable to start their pull due to mechanical trouble, they may drop back three positions, or to last position if they have breakage. They may only do this once. Every effort must be made to drive vehicles on and off the track. The 3 minute rule will be strongly enforced. Push or tow starting allowed only if normal ignition has failed.

If tractor is not started by the 75 foot mark, it must be towed around and ready after the next puller, then if the tractor does not start, you may drop to last position. Two attempts of 75 ft. (50 ft. for Stock class) are allowed to start sled. Sled will not be push started.

Any vehicle that hooks onto the sled and makes a measurable pull shall be considered to have made an official hook, even if the sled is reset and the vehicle cannot re-hook.  Last place points will be awarded.

6. The first puller is the test puller in each class, and may decline the pull and re-pull right away or drop back to third or last position.  If  the puller re-pulls, the second pull will be measured.

7. Shifting of gears on either hydrostatic, automatic, or gear type is allowed, as long as forward motion of the vehicle does not stop.

8. The point of measurement will be where the vehicle either spins out or powers out.

9. Weights only may be changed around after the first pull attempt, if shut down prior to the 75 ft. mark (50 ft. for Stock).

Weights may not be subtracted from or added to the total weight of the vehicle. The first puller may change weights around on his vehicle after his first pull if he decides not to accept the pull.

10. Loss of weights will be cause for disqualification, including first puller, if the mechanical sled is not changed for the next puller. If it happens during a pull-off, it will be the point of measurement and you will be dropped to last place in the pull-off.

11. Loss of anything besides weights will be up to the discretion of the judge whether to let the pull continue or to let that be the point of  measurement.

12. Judges have the right to weigh a tractor before or after a pull.

13. Driver must remain in the seat at all times, with at least one hand on the steering wheel. Hands must not be placed underneath the fender edges.

16. There will be no drinking of alcoholic beverages by pullers, pit crew, track workers or the sled operator within 25 feet of the track during pull.

17. Excessive loss of liquid by a pulling vehicle while in forward motion during a contest on the track will be disqualified, unless due to internal breakage. Excessive is defined as a steady or intermittent stream discharged onto the track, or a spot equivalent to more than 8" in diameter.

18. Vehicle going out of bounds: Any pulling vehicle tire that touches out of bounds lines will cause disqualitication; unless the eliminator forces it out. If the vehicle is beyond the end of track (orange) cones it will not be disqualitied. On first attempt for first puller only - puller will be allowed to re-pull regardless of where the vehicle went out. All others - ifthe vehicle goes out of bounds before the 75 ft mark and the puller attempts to stop before the 75 ft mark the vehicle will be allowed to re-pull. If you go out of bounds during a pull-off, it will be point of measurement and you will be dropped to last place in the pull-off. (re-worded for claification only)

19. All decisions of the judges are final. Judgment calls by the Track Judge are not subject to appeal. Once the Red flag is out it  will stay out.

20. Judges have the right to not let any driver/tractor compete they feel is unsafe. The Track Judge may stop any pull attempt  considered unsafe. The pull will be measured at that point.

21. If Puller starts to pull while Judge still has the Red flag out, the pull attempt is forfeited, puller must stop. If the Judge has   given the Green flag but the Sled still had Red Light, the pull will be stopped but the attempt is not forfeited.

22. Disqualification will result if driver does not attempt to stop when Red flagged for any reason.

23. If the sled rider feels a dangerous condition exists on the track, he may pull the sled brake and issue a re-pull for that puller.

24.  Once a vehicle is hooked to the sled and any breakage to the vehicle occurs, no refund of entry fee will be made for that class. Any  competitor who breaks at an event (or provides notification prior to class start of breakdown in-route to the event) will receive 5 hook points for all classes entered, but will not receive any prize money unless a measurable pull has been made by that vehicle in that class. Verification may be requested.

The zone will consist of the first full pull line and the end of track line. Any puller reaching the end of track line will automatically qualify for a pull off and/or up to the top 3 distances in the pull off zone.

28. These rules must be followed in order for the pull to be sanctioned by WGTP Inc.
