All drivers under the age of 18 must have a parent or legal guardian signed consent on file with BRMGTPA. NO EXCEPTIONS! Minimum age is 5yrs (maximum 12yrs) for Junior Stock class. Junior class pullers may participate in the Pure Stock (if they are truly Pure Stock to begin with) or Hot Stock classes with the same tractors they are pulling in the Junior Stock class and with the same safety rules as is stated in the Junior Stock class; ¡¡10yrs minimum age for Pure Stock and Hot Stock class tractors (10-12yrs age pullers will have to have a safety kill switch held by parent or guardian as outlined in the Junior Stock class); 13yrs minimum age for all Modified class tractors; 15yrs minimum age for all Super Modified and Mini Rod class tractors.

Drivers must wear shirts, closed toe shoes (no sandals or flip-flop type shoes), and either short or long pants.

All vehicles are subject to safety and class eligibility checks by officials for compliance with rules.¡¡ Passing of safety and eligibility inspection may be required at each sanctioned event prior to allowing the vehicle to compete.

Any competitor refusing to have his/her vehicle inspected for safety and eligibility shall not be allowed to enter and/or pull in the class or classes in question until legality is established.

All drivers should be clean and neatly attired.¡¡Tractors should be clean and painted.

It is mandatory that all drivers attend any driver meetings that may be held by the promoter and/or officials.¡¡ At the discretion of the official, a driver who does not attend a driver meeting may be disallowed to compete during the accompanying session of pulling.

Any member that tries to make conflict in any way to dishonor the association to his/her benefit will be put on probation or may be discharged from the club.

Any tractor legal in any class will be legal to pull in a class higher on the performance scale. This is determined by the track officials or class specific rules as outlined.

Any tractor meeting safety requirements but no class exists for it, may be allowed to pull as exhibition at a time during the pull designated by the pull director or his designee.

A single tractor may not take more than 1 place for class weight division. IF an event allows more than 1 driver per weight class, 1 must be designated as the puller of record. The other pull will be for exhibition only and must pull in order/position after the designated puller of record. Each puller must pay an entry fee. Only the tractor/driver listed as designated will receive trophy, points, or place.

Pull director or his designee shall determine the number of hooks allowed per driver/tractor combination at each event. This is not typically less than 4 unless specified prior to start of event.

Points:

Participant must be a member of the club in order to receive points.

Points shall be awarded to any BRMGTPA registered tractor/driver combination that has legally entered and passed tractor inspection at that sanctioned event.

A vehicle may collect points in more than one division that it is legal to run in.

To be eligible for points championship, regardless of total points earned, you must participate in a minimum of 50% of regularly scheduled pulls for that point year.

Points will be given to the tractor/driver combination

If the end of season points race results in a tie, comparing the number of 1st place finishes during the season will break it.¡¡ If a tie still exists, 2nd place finishes, 3rd place finishes, and etc. will be counted until the tie is broken.

The Points Committee reserves the final authority to settle any questions or disputes regarding point awards.

All published club pulls are point pulls unless specifically stated as a benefit or "fun pull".

If an event it called due to inclement weather and a tractor/driver combination has registered to pull in a class/weight division at that pull, then that tractor/driver combination will receive 1 point. This is designed to reward people that make the effort to come out and support the club pulls.

Contest Procedures:

A drivers meeting will be held prior to the pull starting. As soon as the drivers meeting is finished the first pulling class will line up and be ready to start.

Prior to pull starting a prayer will be said and the National Anthem will be played.

Contestants must pull in the position drawn or order determined by pull director.¡¡ In case of mechanical breakage, which has been confirmed by an official, contestant may drop to last position.¡¡ If breakage is not evident, puller may drop to last position - this will constitute the puller's first attempt to pull and therefore will only have one remaining attempt to compete.¡¡

From the moment that both track and sled are prepared for competition, the puller has 3 minutes to hook and make his/her attempt to pull.

Each driver has the right to have the sled spotted to a particular location on the starting line.¡¡ The driver or assigned crewmember is responsible to clearly request the location before the sled is returned to the starting line.¡¡ In the case of a second attempt, a second location may be requested.¡¡ Entire sled must be within the chalk lines at the start of pull attempt.¡¡ No official pull may be started beyond the starting line or in back of the starting line.¡¡ All sleds must be started in gear and with front of sled even with the starting line.

Each competitor will be allowed two attempts to make a measurable pull.¡¡ An attempt is defined as moving the sled 1" or further.¡¡ On first attempt, if the competitor lets off the throttle before reaching the false start line, the competitor will get a second attempt, even if he/she went beyond the false start line.¡¡ If no attempt is made to back off the throttle, and competitor is flagged before reaching the restart line, no second attempt will be granted.¡¡ Intent is not to slam on the brakes in order to stop before the false start line (or any time), but come to a smooth safe stop. Even if competitor goes out of bounds or looses weight, if throttle is let off prior to false start line, puller may rehook for second attempt. False start line for Stock Tractors is 50 feet. ¡¡Modifieds and up is 75 feet.¡¡

On any re-pull caused by contest malfunction (gear reset, etc), the competitor may either re-hook immediately or drop to last position.

Competitor will be able to drop to last or rehook immediately if breakage occurs on his/her first attempt and he/she has let off the throttle previous to crossing the false start line.¡¡ Puller will be eligible for 1 more attempt.

If a class is restarted, all competitors having previously pulled will, in descending order, have the option to drop to last but not forfeit any pull attempts.¡¡

If the last competitor in the class has difficulties, this puller will have 5 minutes to hook to the sled and make their first attempt to pull.

If a tractor is legal when hooked to a sled and breakage occurs while under the green flag due to unforeseen circumstances, the pull will be measured with the exception of excessive loss of weight, or going out of bounds on the same pull attempt.

All tractors must be in neutral/park while being hitched and unhitched to/from sled.¡¡ During this time, the puller will show/raise hands in clear view as proof of safety to "hooker".

All pulls are to start with a tight chain. No jerking of the sled.

Any equipment or condition deemed unsafe by track officials must be corrected before you will be allowed to compete.

A "floating finish line" may be used at the discretion of the head official and the sled operator in a pull-off situation only.¡¡Competitors must be informed of floating finish line prior to the pull-off.¡¡ This is an option and not required at any event.

Order of pull-off will be in the order which the vehicles made full pulls

The decisions of the track officials are final.

Tractor Operations:

All tractors must be operated in a safe manner at all times. Tractors with only one seat will have only one occupant.¡¡ This is to include tow and maintenance vehicles. Whenever tractor is under its own power but not hooked to sled, speed shall be comparable to being towed.

From the time it is hooked and the tractor is stopped by the flagman, no one, except track officials may be in the track between marked lines during this time or the tractor may be disqualified.

Only the driver will be allowed on the tractor at any time. Drivers will not use excessive speed at any time during an event. Tractors will not be left running unattended at any time.

When the driver pulls up to hook to the sled, they must put their tractor in neutral, and take their foot off the clutch or drive mech. They must put their hands in the air and let the hook-man and sled operator know that they are ready to hooked to the sled. The tractor will not be hooked or un-hooked until this is done.

When a tractor is hooked to the sled the¡¡hook-man¡¡will roll the tractor forward to¡¡tighten the chain before the pull starts.

The puller will not start the pull until given "OK" ok by the sled operator and flagman.

The puller will not jerk start the sled. If this happens the pull will be stopped and second pull will be made. If this happens again, the puller will be disqualified.

Flagman has the responsibility to stop any pull attempt considered unsafe.

Causes for Disqualification:

Decisions of the¡¡event officials are final. Arguing with event officials can/will result in event disqualifications or suspension on second occurrence, membership can be revoked for one year from date of second occurrence.

Any competitor or member of his/her crew to be under the influence of any intoxicating agent, drug, or having a blood alcohol content during contest activities shall be barred from any further involvement or participation in the event and suspension, or termination of membership.

Unsportsman-like conduct will result in disqualification.

Tractor driver must remain seated during pull and maintain control of the tractor at all times. There will be no sitting up on the back of the seat. A reasonable amount of leaning will be allowed. One hand must remain on steering wheel at all times. Not doing so will result in disqualification.

Using edge of fender as a grasp point to obtain "leaning leverage" will result in disqualification.¡¡ Sturdy handles may be installed for this purpose.

Weights must be securely attached to tractor. Any obvious or excessive loss of weight during the course of the pull shall result in disqualification.*(see below) Flagman must make call during the pull. This is defined as the time between the start of the sled moving until it stops moving, even though tractor may still be under power.

During the pull if tractor touches boundary lines or ground on the other side of the boundary line, will result in disqualification.*(see below) There will be no "out of bounds" after the full pull mark.

Any contestant attempting to leave under the red flag may be disqualified.

Failure to have safety equipment in place will result in disqualification.

Jerking of the sled after being warned will result in disqualification.

Deliberate attempt to cause slack in the chain while under the green flag, is reason for disqualification.

*In the cases of loss of weight and going out of bounds, the driver/tractor will still receive last place points for that class. Number of entrants will determine this point number. If more than one contestant is affected in this manor then they will be rewarded the same points. This is for these two situations only. All other disqualifications will result in loss of points and place.

Protests:

Verbal protest must be made within 5 minutes after the end of the class in question.¡¡ This must be followed by the formally written protest, which must be delivered to the entry clerk within 30 minutes of receiving¡¡form which will be made available by the promoter or BRMGTPA official.

The protest must specifically identify the nature of the violation.

The protested tractor can be pulled in other classes at that event before submitting to be checked.

Tear down is by owner or owner's mechanic.¡¡ At the request of the owner of the tractor in question, this process may be completed with the only witness being the owner, owner's mechanic and the BRMGTPA official.

If protested driver will not submit to inspection, he/she will be considered illegal.¡¡ An illegal tractor must be proven legal before being allowed to compete again.¡¡

A tear down protest deposit consists of a deposit of $250.00 for the first item, $100.00 for each additional item in question.¡¡ This deposit shall be made at the time of protest.¡¡ Protest must be made by anyone competing in the same class as the vehicle in question.

For each protested item found to be legal, the protester shall forfeit the corresponding deposit.¡¡ If said tractor is illegal, the owner will forfeit all winnings, entry fees, and points of the day for all classes that the tractor would be in violation.¡¡ The deposit for all items proven illegal will be returned to the protester.

The BRMGTPA official shall decide the protest as promptly as possible and shall inform the parties of the protest decision. Officials decision shall be, will be and is final.

Stabilizer Bars:

All tractors must have a device (stabilizer bars or wheelie bars) to prevent turnovers. No exceptions!

No spring loaded stabilizer bar devices.

The device must consist of 2 separate sections, each equipped with either a skid plate or wheels.

Skid plates are to be at least three square inches each at the ground contact point.

Wheels should be at least 1" wide and 4" in diameter or roller devices must be OK by safety officers.

Skid plates or wheels shall be no less than 5" behind the rear most part of the rear tires to center of stabilizer wheel axle or tip of skid pad and no more than 5" above the ground. Tolerance on height is + 1/4" (5 1/4") and behind tires - 1/4" (4 3/4")

Stabilizer bars shall be rigid enough to support the weight of the tractor.

No part of the stabilizer bars shall interfere with the sled chain or hook.

6" tall bumper bars are not mandatory but are recommended on all Modified, Super Modified, Mini Rod and Super Mini Rod classes. These would consist of a bar extending vertically 6" from the rear most tip of skid pads or wheels on the stabilizer bars. The top of the vertical bar would be supported by a brace, which extends to the wheelie bar, chassis, etc

Kill Switches

All tractors except stock RPM limited classes are required to have a switch that will kill engine and electric fuel pump in case of chain or hitch breakage. The switch will be located within range of six (6") either side of center of back of tractor with a minimum of a 1.5" circle. Switch must be located as not to interfere with hooking to the sled. Comment: Stock class tractors are strongly encouraged to have the same kill switch, but not mandatory.

Junior Stock classes are required have a working kill switch to be held by a parent or guardian walking safely alongside the tractor. This kill switch must disable ignition and electric fuel pump (if equipped).

On diesel engines, the kill switch must activate the air shutoff - no electrically operated air shutoffs. Diesel system may use a spring-loaded cap activated by a cable. Diesel system shall be deemed acceptable if it at least prevents the building of boost.

Fire Extinguishers/Helmets

All tractors except stock RPM limited classes are required to have a fully charged, functional fire extinguisher with a gauge within easy reach of the driver (minimum of 1 ¨ö lbs [2 ¨ö lbs recommended] dry chemical or CO/2-type extinguisher). Comment: Stock class tractors are strongly encouraged to have a fire extinguisher, but not mandatory.

All tractor drivers except those pulling in stock RPM limited classes are required to wear a DOT approved or SNELL rated helmets with chinstraps fastened.

Fire suits are not mandatory but are strongly recommended in the Modified, Super Modified, and Mini Rod classes.

Drawbars:

All tractors must be equipped with a drawbar that is horizontal and stationary in all directions. Hitching device shall not more than 3/4" or less than 1/2" in thickness and must have a 1 1/2" hole for hook. Pulling point may not be more than 3/4" from back edge of hitching device.

Pure stock tractors may use a clevis loop in a factory hitch hole so long as it has a 1 1/2" hole and is equivalent to ¨ö" rod in diameter.

Pulling hitch should be made of steel or equivalent.

Drawbar must be parallel to the ground, and not more than 13" above the ground. No more than 15" on Mini-rods.

Nothing can interfere with the drawbar hitch or sled chain;¡¡drawbar hitch must be readily accessible.

If the adding of air or the removing of air in the front or rear tires occurs after crossing the scales and entering the staging area to pull, then the driver and tractor must have the drawbar hitch height re-measured.

Weights/Weigh-in:

Weights cannot interfere with hooking to the sled.

Class weight will include the tractor and driver.

All tractors must have stationary weight brackets (front weight brackets/bars can be extendable but must be able to lock into a stationary position once desired length is achieved before pulling sled).¡¡ No weight in either the seat or hook point.¡¡ All weights must be secured to the tractor.¡¡ Weights are not to extend more than 5" beyond the rear-most part of the rear tire, nor shall they be positioned more than 8' from the center of the rear axle to the front (stock classes are no more than 6¡¯ from the center of the rear axle to the front)

Weigh-in will occur before the pull is attempted.¡¡ Tractor must have all safety equipment in place; have sufficient fuel, oil and water if applicable and driver in the seat.¡¡ No adding of fuel, oil or weights after crossing the scales and entering the staging area unless re-weighing.¡¡ If this happens, the driver and tractor must cross the scales again and re-weigh. Existing weights may, however, be relocated without repercussion.¡¡ No tractor exceeding class weight will be allowed past scales and into the staging area.¡¡ Weight includes driver and tractor and a 1% tolerance that will be allowed for all classes. This allowance will be given due to possible scale fluctuations; however, there will be no leniency on the accepted weight.

All weights must be safely secured to the tractor. Any excessive or obvious loss of weights or components may be cause for disqualification. Comment: The flagman must make the call during the pull.¡¡ Any disqualification for loss of weight or component must be made during the pull.¡¡ A pull is started when the sled starts to move and is ended when the sled stops movement, even though the tractor may still be under power.
