2009/2010 RULES

MIDDLESEX COUNTY TRACTOR PULLERS INC.

CLASSES

Tractor and driver cannot weight over:

Technical rules and specifications will be in effect for two (2) years. The intent of these rules is to provide a safe and fair contest. Decisions made by the Technical Committee may temporarily or permanently supersede any mechanical rule. It is ultimately the obligation of each participant to ensure that his/her conduct and equipment comply with all applicable MCTP rules, as they may be amended from time to time. These rules are designed to provide for the orderly conduct of the motor sport of garden tractor pulling and to reduce the risk of injury to both participants and spectators during such events.

SAFETY RULES
(Applies to all classes)
 

1. Each tractor will be inspected by the Technical Committee.  The committee will make the final decision as to which Class the vehicle conforms to. and/or whether or not it meets the safety standards. Tractors are eligible for one (1) division only.

2. Helmets (half or whole) must be worn by all drivers during the pull  (full face helmets are recommended).  Helmets must be D.O.T. rated, strapped, and fit properly. Pullers must wear appropriate shoes e.g., no flip-flops.

3. Drivers shall wear SFI approved single layer fire suits for any alcohol-burning tractor regardless of class. Full body coverage is required (Top & Pants) all fire suits shall be securely fastened (zipped up).

4. No driver shall bounce on the seat or stand for any reason while pulling. Driver will keep at least one hand on the steering wheel at all times during the pull.

5. Nothing shall extend more than 3” beyond the outside of the rear tires.

6. Modification of tractor controls are required to fit the driver.

7. Open to two-wheel drive, rubber tired tractors.  No dual wheels, chains, or spikes.

8. ALL tractors must have sufficient shielding of belts, chains, etc. to deflect flying parts to the ground. All vehicles must have functional brakes and steering. Stock tractors must have reverse, and all exhaust pipes (if other than stock) must point up plus or minus 10 degrees.

9. All tractors that do not have a 4000 RPM rule must have a dead man throttle.

10. All tractors are required to have a kill switch (with a 1” ring) that will kill engine and fuel pump located on back of tractor within 6” of center. Lawn Stock tractors are exempt from this requirement. See individual class rules for specific requirements regarding electric fuel pumps.

11. All children in the pulling area shall be supervised at all times. There shall not be any climbing on or playing around the tractors and equipment used for track maintenance.

12. There will not be any “pullbacks” by the sled. This is because the sled operators have a difficult time steering the sled when pulling a tractor back and it is deemed unsafe.

GENERAL RULES

1. Pullers must join the Middlesex County Tractor Pullers Inc. A Family Membership is available for a $25 annual fee.  This membership is limited to immediate family members living under the same roof. A One Day Membership is available for the amount of $10/tractor/day plus $5 to cover insurance costs for non-members. One Day Members will NOT receive points towards the season totals!  Minimum age requirement for stock classes is 5 years old and for all other classes is 12 years old and/or have at least 1year prior experience in stock classes. The tech committee will conduct driving tests as they feel necessary to ensure that each puller is capable of safely operating their tractor. 

2. All tractors must weigh in for each class.  Starting numbers will be drawn randomly at the time of registration.  You must register for the class you wish to pull in before it begins. Tractors may only pull in one class per event. A fee of $10/tractor/pull must be paid at this time.  Again, One Day Members will pay $15/tractor/pull.  Note: If only entering 950 lb. A Stock Jr. Class, the entry fee will be $5 for members and $10 for non-members.

3. All placing tractors must re-weigh after each class, if not, you will forfeit your winning position if it is contested (this will be at the discretion of the Club Officers and Tech Committee at each event).

4. Length of track will be 200 ft. maximum, 20 ft. wide whenever possible.  No one will pull unless a field judge (flagger) is in place at the time of the hook.

5. Each puller in each class will have one pull only per heat, unless he/she does not reach the 25 foot mark (shutdown rule: the puller must make it known to the flagger and or sled operator of his/her intent to shutdown within the 25 foot shutdown distance by raising one hand or equivalent). He or she may take the first hitch or have a second hitch immediately thereafter. If a second hitch is taken, the puller must keep the second pull distance.

6. The competitor pulling in the 1st position of each class, determined randomly at time of registration, is considered the test puller. Once the weight transfer on the sled is considered correct for that class the test puller may: A) accept their pulled distance; B) refuse their distance and immediately hook up for one more attempt; or C) refuse their distance and pull in the third position.  Third position is considered to be after the next two (2) competitors have pulled.  It is the test puller’s responsibility to inform track officials of their decision as soon as possible. (Note: dropping back to last position is prohibited unless due to mechanical reasons at which time must be authorized by a member of the Technical Committee.)

7. The drawbar will be 13” from the ground to the top of the hitch and solid to the tractor with no up, down, or horizontal movement. No clevis. Hitch must consist of a horizontal plate or equivalent with the hitch hole perpendicular to the ground plane. Drawbar must be no more than 15” from the center of the axle to the rear of the tractor to hitch point. Rear engine tractors are the one exception, with the hitch being as close as possible to the engine. Hitch must be easily accessible for the hook. There shall be ample clearance without any obstruction from weights etc

8. The hitch must have a minimum of a 1.5” hole (a 1.500 dia. steel ball shall pass freely through the hitch hole) No hydraulic or electric hitch systems are allowed. Hitch point must be to the rear of the rear axle centerline.

9. Tractors must have wheelie bars, which will be no more than 5” from the ground, must extend 4” minimum behind the exterior of the rear tires, must have a minimum of 1” square pad or wheel at ground contact point, and must be able to support the weight of the tractor and driver.

10. The 950 lb. A Stock Jr. Class is limited to drivers ages 5-12 years. If a puller starts the season as a junior and becomes 13 during the season, he/she will remain a junior for the remainder of the season (For this purpose, the season begins April 1st. Anyone whose 13th birthday is before April 1st will be considered a senior.). All Jr. pullers will be required to exhibit his/her competency at operating their tractor safely. The tech committee will conduct driving tests as they feel necessary to ensure that each Jr. puller is capable of safely clutching, de-throttling, braking, reversing, etc. their tractor.

11. Tear down or other testing may be done to verify that the tractor is registered for the correct class. Driver/owner and two (2) members of the Technical Committee shall be present.

12. All tractors except those pulling in the Super Outlaw class shall be normally aspirated. Superchargers, turbochargers, nitrous oxide injection or any other type of fuel or additive injection or forced induction is prohibited.

13. In the event of a protest by a puller in any given class, if the protestor requests a teardown of a tractor within his/her class, (protestor must be competing in the same class as the tractor in question) the protestor will be required to file a protest form with the Technical Committee. The protestor requesting the teardown will also be required to escrow $50.00 per tractor with the Club Treasurer at the time of filing. At the completion of the teardown, if the tractor in question is found to be illegal, the money in escrow will be returned to the protestor. The illegal tractor will forfeit all points accrued for the current pulling season.

14. In the event the tractor in question is found to be in compliance with all applicable rules for the class, the money will become the property of the puller whose tractor had been torn down.

15. If a puller refuses to have his/her tractor torn down, he/she will forfeit all points accrued for the year and will not be allowed to pull the tractor in question until it has been approved by the Tech Committee.

POINTS SYSTEM

Points will be issued according to the following schedule:

Eleventh through last places will receive 1 point less for each consecutive place, e.g.: Eleventh Place 20 points, Twelfth place 19 points, etc.
In the event of a cancellation for any reason prior to the start of a pull, there will not be any points awarded. If a pull is cancelled for any reason after any heats have been completed, the points for those heats will be awarded on a regular basis. Any tractor in any heat in any class that did not finish or that did not begin prior to the cancellation will be awarded 25 “show-up” points each.
If a puller signs up for the day and his/her tractor breaks after attempting a legitimate pull in the first heat (under its’ own engine power-no starter motor assists etc.), the tractor will receive last place points for the subsequent heats of the day. Tractors will not be required to hook to the sled to receive these subsequent points. Technical DQs will not receive any points for the heat (e.g. overweight, hitch height, over RPM etc.) Moving violation DQs will receive last place points for the heat (e.g. out of bounds, 2 hands off steering wheel, standing up while pulling etc).
 

MAKE-UP PULLS

GROUNDS FOR DISQUALIFICATION

1. A competitor will be disqualified from the heat in which the offense took place for the following reasons:

   1. Disruptive behavior

   2. Unsportsman-like conduct

   3. Reckless operation

   4. Inability to operate vehicle completely by him/herself

   5. Not meeting or exceeding class specifications

2. Tractors that contact the foul line at any point prior to the full pull mark for the class while hooked to the sled will be considered out of bounds and disqualified from that specific hook. The flagger has the ultimate judgment call.

3. All weights must be safely secured to the tractor. No weights will be allowed on tractor seats or on the driver. Any excessive or obvious loss of weights or components may be cause for disqualification. Comment: The intent of the rule is for safety and fairness. It is the flagger’s decision, if any weights or components fall off the tractor and move to the side of the path of the sled it would not affect the outcome of the pull. However, if the weight or component falls off and goes beneath the sled pan, it may affect the outcome of the pull and therefore the pull shall be disqualified. (The point is that a steel weight or component would make the pan slide easier over it and may increase the distance of the pull.)

4. Pulling is defined as the tractor moving while the sled itself is in motion.

5. Obvious or excessive consumption of alcoholic beverages or drugs will be grounds for disqualification.

6. If disqualified for any reason, that offense must be re-inspected by the Technical Committee.

NOTE: TRACTORS ARE NOT DISQUALIFIED UNLESS A TRACK OFFICIAL SPECIFICALLY NOTIFIES THE STATISTICIAN AND/OR ANNOUNCER PERSONALLY BEFORE THE NEXT HITCH.
