    National Micro-Mini Tractor Pullers Association

          The National Micro-Mini Tractor Pullers Association sanctions 
    pulls throughout North America.  Standard rules are provided, assuring 
    members that their vehicles will be legal at any pull they may choose to 
    attend.  The association also sponsors a points contest.  A puller earns points
    at each pull towards a "Points Champion" award for their state or province.
    Awards are presented each year at the annual meeting.  The association also
    publishes the "Puller's Post", the newsletter of the association, thus letting
    members know where the sanctioned pulls will be held.  Another major benefit
    of being a member is the $1,000,000 liability insurance policy each member 
    enjoys while pulling.  Join now and enjoy all the thrills of pulling micro-mini
    style!

    General Rules

    1. All judge’s decisions are final. Misconduct will cause disqualification and loss of points in each class pulled at the judges’ discretion.

    2. All pit and track areas must contain only pullers and officials - no spectators.

    3. NMMTPA official sanctioned classes are: 3 lbs. Pro Stock, 4 lbs. Two Wheel Drive, 5 lbs. Pro Stock, 6 lbs. Four Wheel Drive, 5 lbs. Super Stock, and 6 lbs. Open.

    4. Each vehicle may be entered in more than one class, but only once in each class. A vehicle is defined as a driveline, body, tires, and engine. These components may not be interchanged in each class.

    5. The first puller (test puller) of each class has the option to drop his first pull and pull again for his official pull pending his/her immediate decision. No test pulls (pull-overs) are allowed in a pull-off.

    6. Contestants will be allowed two attempts to cross the 4’ mark on a 16’ track and the 6’ mark on a 24’ track. However, in a pull-off, only one attempt will be allowed.

    7. Pulling measurements are to be taken from the front center of the skid plate. Full pulls are 15’ or 14’ (optional) on a standard 2’ x 16’ track. Full pulls on an optional 2’ x 24’ track are 21’ (the use of the optional 24’ track must be advertised with the pull information in the "Puller’s Post"). Track specifications are listed in the technical section.

    8. The track will be cleaned between each puller in the class by the track judges only.

    9. Any part of a vehicle tire or sled leaving the edge of the track during a pull will have the distance measured to that point. Anything (weights, nuts, etc.) that falls off the pulling unit during a pull will result in the pull being measured at that point. The pull will be stopped by the table judge and measured if one drive wheel (or wheels on one side of the pulling unit) is raised off the track for a traveling distance of more than six consecutive inches. This decision is to be made at the judge’s discretion.

    10. All vehicles are to be guided with a clear plastic guiding device termed a "guidall", with the following requirements:

    A. The guidall must be kept flat on the track surface and parallel with the vehicle.

    B. A 7 inch (inside width) guidall must be furnished for use in the Pro-Stock and Super Stock classes. Both a 7 inch and 10 inch (inside width) guidall must be furnished for the 2WD, 4WD, and Open classes. Only a 7 or 10 inch guidall may be used at a pull.

    C. Must maintain 1 inch minimum clearance between weight bracket, front end, tires, axle, etc. (any part of the vehicle) and guidall.

    D. The guidall must measure 6 inches minimum height and be square on all surfaces. The "arms" of the guidall must be 6 inches in length.

    B. Nothing can be used on the weight bracket, wide frontend, or guidall to help in holding the vehicle on the track. Examples might be glue on the guidall or sharp objects or brads on the weight bracket.

    F. The objective is to guide the vehicle in a straight line only. No zig-zagging or s-ing will be allowed.

    G. The guidall must be assembled so that there are no protrusions on the inside surfaces to catch on weights or weight bracket.

    H. One hand must be on the guidall handle while in the act of pulling.

    11. The type of fuel used is open (use caution). Each puller is responsible for his/her own safety as well as spectators.

    12. No radio controlled vehicles will be allowed.

    13. All pullers will be given a maximum time limit of three minutes to have their vehicle in operation from the previous last pull of the class.

    14. All pulling units must pass a "cotton ball test", wherein the tires will be touched to a cotton ball and removed. If the cotton ball is torn apart excessively, the puller is disqualified.

    15. The weight added to the skid plate can not exceed 5% of the total weight of the sled.

    16. All sleds used at a sanctioned NMMTPA pull must use a chain hitch on the skid plate or pan.

    17. Starter batteries are to be maintained in a safe manner.

    18. All vehicles must be inspected immediately after each pull. The hitch of the vehicle will be checked as pulled. No rotation of tires is permitted.

    19. Having once entered, pullers can get entry money refunded upon withdrawing from the class before the individual class has started.

    20. All pulls must be listed in the "Puller’s Post" that is expected to be delivered before the pull date or it’s not a sanctioned pull.

    21. Must be a NMMTPA member to enter and pull at a NMMTPA sanctioned pull.

    22. A puller must enter a minimum of five pulls to be awarded the shirt, plaque or any other points champion award. There is no minimum on the number of points earned. If two or more pullers are tied for 1st place in a state points race, all would receive awards and be designated as co-champions.

    23. The only points of contact with the track by the vehicle shall be with the wheels. Weights, weight bracket, gears, and all parts of the vehicle must clear the track.

    24. Sled hitch height at the skid plate shall not exceed 1 inch from the pulling surface. No minimum height is stated. No length is stated.

    25. The number of entries is limited to two entries per person per class.

    26. No beer or liquor is allowed in the pits or pulling area.

    27. Exhaust stacks, mufflers if used, must point away from the track.

    31. It is recommended that a fire extinguisher be present at all pulls.

    32. On machines that do not have a legal hand throttle cable, the engine fuel and throttle settings can not be manually adjusted after a vehicle is hooked to the sled and placed on the truck.

    33. Hand held throttle cables, if used, must be flexible so that they can not be used to stabilize the machine (at judge’s discretion) and must not become taut.

    34. If a proposed rule change is voted down by the membership, that same rule change shall not be resubmitted for voting for at least three years.

    35. A pulling attempt (or hook) is defined as when the vehicle’s pulling tires touch the track with the engine running and the vehicle is hooked to the sled.

    36. Once a class has started no entries can be added.

    37. Any changes to the sled, track or scale need to be announced. Whether it's before the start of the class or during the class.

    38. Webmaster is an official board position. The person will be held responsible to the rest of the NMMTPA board.
