GENERAL TRACTOR AND SAFETY RULES

 

The following safety rules are written for your benefit and the benefit of others.  These rules are minimum rules for safety and in no way define a totally safe tractor.  It is up to the owners and drivers to make the tractor as safe as possible.  So please pay close attention to the following safety rules.  PLEASE DO NOT TAKE ANY SHORT CUTS ON SAFETY!!!

 

·         All tractors will be inspected and have a safety permit sticker or tag in place before being allowed to pull.  Tractors not meeting the safety requirements as outlined will not be allowed to pull until corrections are made.

 

·         All tractors must have full hoods, securely fastened fenders, adequate steering and working brakes.

 

·         All tractor fuel tanks and fuel lines must be securely fastened and have proper caps.  All fuel line connections must be securely fastened (crimped, clamped, flared, etc).

 

·         All starter pulleys must have adequate nuts, bolts, and washers screwed in the end of the crankshaft to retain a loose pulley.  All starter pulleys must be made of billet steel and aluminum.  No cast iron or pressed steel pulleys may be used on the engine, these pulleys can and will fly apart at high RPM.  The stock class will be an exception.

 

·         All tractors in modified classes must have a dead-man throttle with forward motion to accelerate.

 

·         All tractors must have scatter shields that cover all rotating parts of the engine and driveline.  The engine must have scatter shield opposite the cam side of the engine.  It must be made of 1/8 inch steel or 3/16 aluminum and cover the full height and width of the engine block and be attached in a secure manner to the frame and head or head plate.  The flywheel and clutch assemblies must be covered 360 degrees with 1/8 inch steel or 3/16 inch aluminum and be securely fastened to the frame or engine.  All belts and driveline shafts, u-joint, flex coupling must be covered 180 degrees with 1/8 inch steel or 3/16 aluminum.  Stock classes must have factory shielding.

 

·         All tractors must have a working kill switch with a ring or loop minimum of 1" diameter mounted on rear of tractor in an accessible position for the sled hooker to hook up.  It is the responsibility of the driver to locate the kill switch so that the rope will not tangle with the rear of the tractor.  A kill switch must kill the electric fuel pump on modified tractors.  A grace period of one pull will be allowed for non-compliance.

 

·         All tractors must have rear anti-turnover devices sufficient to support the weight of the tractor.  A minimum of two metal centered wheels (wheels can be plastic but centers must be metal), 5 in diameter and 1in wide, or two steel pads must be no less than 5" from the ground and 5" from the rear of the tractor tires to the center of the pads. (Motorcycle tractors have their own design shown under the rules for motorcycle classes.)

 

·         All modified single cylinder tractors must have cylinder head restraints of sufficient strength to prevent the head and/or the cylinder from blowing upward in case of failure.  This is recommended for stock tractors also.

 

·         Drawbar will be horizontal and stationary in all directions.  With hitching device not more than 1" in thickness and must have a 1-1/2" hold for hook.  Pulling point may not be more than ¾" from back edge of hitching device parallel to and not more than 13" above the ground.  Pulling hitch should be made of steel.

 

·         All weight and weight brackets must be secured to the tractor.  Front weights must not extend more than 8ft. from the center of the rear wheels.  This is with the exception of 16 stock altered which have 7ft weight bars (NQS Rules).  Rear weights must not extend past the rear tires.  no wheel weights.

 

·         All tractors must have an exhaust that discharges vertically.  Motorcycle tractors exhaust must discharge in the vertical direction above the tractor or can discharge out the back of the tractor between the tires pointed towards the sled pan.  NO SIDE DISCHARGE PIPES THAT ARE POINTED TOWARDS SPECTATORS.

 

 

TRACK SAFETY RULES

 

·         All tractors will be hand pushed backwards to the sled when being hitched or unhitched.  All drivers must place the tractor in neutral, have their foot off the clutch, and signal the hooker by holding both hands in air.

 

·         All tractors must start from a tight chain.

 

·         All drivers must remain seated and keep one hand on the steering wheel at all times during the pull.  No bouncing or jerking the tractor while it is in motion.

 

·         Helmets must be worn in all classes with the chin strap snapped.  Any driver found to not have the chin strap snapped after pulling will be disqualified.   Wear only appropriate footwear for pulling.  NO SANDALS OR FLIP FLOPS ALLOWED.

 

·         Fire extinguishers are MANDATORY on all tractors running on alcohol fuel.  A grace period of one pull is allowed but the next time the tractor shows up to pull it must have a working fire extinguisher or it will not be allowed to hook to the sled.  Fire extinguishers are recommended for all classes but not required.

 

·         All drivers running alcohol fuel are required to wear a minimum of a fire jacket.

 

·         All drivers must be capable of operating tractor on track, including starting, stopping, and forward control, with the exception of the youth classes.

 

·         Speed in pit area must be idle at all times!!

 

·         Helmets, fire suits, and fire extinguishers that are mandatory cannot be taken off as weights.

 

·         Drivers must be 16 years of age or older to participate in the 48 cubic inch, 50.5 cubic inch, Pro Altered and all motorcycle classes.

 

 

 

TRACK RULES: GENERAL RULES OF OPERATION

 

·         Drivers who are not signed up at designated time WILL NOT GET TO PULL

 

·         ALL JUDGES DECISIONS ARE FINAL!  On any point of controversy, any disagreement will result in disqualification.  Vulgar language or use of any alcoholic beverages will be grounds for dismissal and disqualification.

 

·         All tractors will draw for positions.  All tractors will re-pull in order.  If the tractor is not ready when number is called, that tractor will pull when ready or within three minutes after the last tractor.

 

·         Maximum of one pull per class.  Tractor may be entered only one time per class (With the exception of 8 and 10 hp classes.  Any one tractor can be entered twice in a class with two different drivers and receive payback for two positions).  Tractor may enter a class as long as re-pulls have not yet started.  Tractors may enter a maximum of 2 classes per tractor.

 

·         Drivers will have two attempts to move the sled.  Must pull past the point of no return (50' mark for most classes) to start an official pull.  If tractor does not attempt to hook to the sled, a refund will be given.

 

·         Pulls may be measured electronically or mechanically.  Regardless of how pulls are measured, all decisions of track officials are final.

 

·         The track will be graded between pulls when possible.

 

·         Weights must be changed before hitch height is checked.  Driver must be in seat with helmet before any measurements of hitch is taken.

 

·         Immediately after unhooking, all tractors must go across the scale in front of the announcer's stand to have weight checked.  It is the driver's responsibility to make sure they weigh correctly after pulling. 

 

·         All persons, other than the driver and helper and judges, are to be off the track before any tractor pulls.

 

·         In case of sled weight change, the tractor will be allowed to shift or change weight, but will be allowed to re-weigh and have the hitched rechecked.

 

·         Rules committee will reserve the right to refuse to let any individual hook to their sled for any reason.  Board members will serve as rules committee.

 

·         The rules committee has the right at any time to inspect any tractor to ensure it is passing all rules of its class.

 

·         The driver must keep the tractor under control at all times and operate it safely at all times on and off the track.

 

·         Sled weight will be determined by sled operator by the third tractor pulled in each class.

 

·         The first puller has the option to turn down their first pull and come back to re-hook at his choice position in the class regardless whether the first attempt was a legal pull or not.  First pullers must however, make an attempt to move the sled before turning down and coming back.

 

 

DISQUALIFICATIONS: FLAGMAN'S DECISIONS

 

·         Any act or manner of driving, which would cause bodily injury to the driver or the spectators, will be grounds for disqualifications.

 

·         If a weight or part falls off any tractor after passing the point of no return (50' for most classes) the tractor will be disqualified.  This includes past 200' and if a weight bounces off after clutching the tractor at the end of track.  The pull is not considered over until tractor is unhooked from the sled.

 

·         Weights cannot be in a dangerous position on tractor and must be securely fastened.

 

·         Drivers must have one hand on the steering wheel at all times.

 

·         Driver must remain in seat of tractor at all times when pulling.

 

·         If the tractor tire or tires touches or goes over the boundary line tractor will be disqualified.  THERE WILL BE NO MORE JUDGEMENTS MADE AS TO WHETHER DRIVER WAS TRYING TO STOP, IF YOU ARE OUT, YOU ARE DISQUALIFIED.

 

·         Anyone caught pulling with their hand underneath the fender can and will be disqualified.

 

·         FOR THE SAFETY OF THE PULLERS, SPECTATORS AND THE CLUB'S EQUIPMENT; NO DOUBLE CLUTCHING IS ALLOWED IN ANY CLASS.  ANYONE CAUGHT DOING THIS WILL BE DISQUALIFIED IMMEDIATELY.
