It is strongly recommended that weights be at least 3 inches off the ground and a skid plate with a 1- inch radius rolled front edge be placed under extendable front weights so that no part of the weight touches the ground and it does not interfere with operation of tractor. It is also recommended that extendable weight frames have a lock pin to prevent frame from disengaging.
39. It is strongly recommended that vehicles with reverse gear (except Stock) have a white backup light, minimum 2.0 diam.
40. Changes in class specification rules can only be made at the annual WGTP fall meeting with the exception of handicap limits and shielding. WGTP Board of Directors retains the right to correct rule misprints or misinterpretations based on the meeting minutes.
41. The WGTP Board may determine 2 pulls at which a rule or rules proposed at the spring meeting will be implemented for experimental purposes. No points will be awarded to competitors joining a class under experimental rules.
42. Any violation of any of the General rules, will be cause for disqualification.
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 drivers 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.
14. If the kill switch pulls out more than twice while pulling, it will be point of measurement, unless the sled is the cause of the pullout.
15. Judges have the right to disqualify any driver for drinking alcoholic beverages.
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 at any time will be disqualified. First puller only will be allowed to re-pull. If it happens during a pull-off, it will be point of measurement and you will be dropped to last place in the pull-off. Any tractor tire that touches out of bounds lines will cause disqualification, unless the eliminator forces it out, or unless the tractor is beyond the end of track (orange) cones.
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.
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.
25. No hot rodding on, off, or around the track when not pulling, including tow vehicles.
Off track speed limit not to exceed 5mph, subject to the discretion of track judge or WGTP Board.
* 1st time : Warning
* 2nd time : Disqualification
(ATV type vehicles used for towing machines on and off the track must be operated by someone meeting the state imposed age limit.)
26. When a pull-off occurs, there will be two attempts of 30 feet to start the sled.
27. The use of floating finish lines will be determined by the Board of Directors and the sled operators. Unless otherwise announced at each pull, a pull-off zone will be established. 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.
1. Any protest must be made within 15 minutes after the class is done, and will be brought to the board at that time and settled before any prize money is distributed. Protests for fuel and teardowns can not be made outside of class participated in.
2. Any protest to the legality of a vehicle engine must be accompanied by a teardown fee, $20.00 + the cost of gaskets. The owner of the vehicle will remove the head, carb, or both, whatever the Tech. inspector wants. Refusal is automatic disqualification. If found to be legal, the owner will receive the protest fee. If the vehicle is found to be illegal, the protester will get his money back and the illegal vehicle will be disqualified from all classes ran that day. The offender must prove legality to the WGTP Board upon return to competition, and pay re-registration fee of $50.00.
3. Tech. Inspectors or Board members have the right to check specific gravity of a competitors fuel at anytime. Any reading over the maximum listed under each division, on the club appointed hydrometer, will be disqualified even if found before the start of the pull. WGTP Board retains the right to check carbs, weight, and drawbar at the completion of an Individual's pull. The puller will be notified prior to leaving the track.
4. Classes with cubic inch limits will use the following formula: .785 X Bore X Bore X Stroke X Number of Cylinders
5. When disqualified for going out of bounds, loss of weights, or loss of liquid, the puller will get last place points for the class.
6. When disqualified for illegal fuel, engine, carb., drawbar, over weight, or improper equipment, the puller will get no points, no hook points, or no prize money for any classes run that day.
7. The WGTP Board retains the right to suspend members causing or participating in disturbances on or near the track, from participating in the balance of the event. No prize money, refunds, or points.
