October 3rd, 2016

Hello NATPA and Fellow Pullers,
The NATPA Board of Trustees and I have gone through all the NATPA Division Rules. As you know-things were not correct or rules just became missing from changes in formats, staffing and websites. The rules are hopefully up to date and correct. I’m sure I missed some things which you can point out to me and I will make the proper changes. Anything is an improvement from the wording we had before. I tried to make the Division Rules more worker friendly to look up a rule or regulation for that division.-Bob DeBerg, NATPA President

  1. “NEW” Division I Weight Rule for 2018 WEIGHTS – Manufactured original factory weights for that make and model are allowed. Weights of bolt on type to either the front or the back wheels are allowed. Weights can be made. The wheel weights must be round and made of metal, cast or aluminum materials and be as near appearing to original manufactured weights as possible. No concrete weights allowed. Moveable suitcase weights can be used in front of the rear axles and or behind the front axle of the tractor.

GENERAL RULES #11 as it Reads Now.

  1. SAFETY EQUIPMENT – In DIV’s IV, V and V+ ALL tractors must be equipped with a high back seat measured 7 inches from the base or cushion. Fenders and a dead man’s throttle: (Except hand clutch models) are mandatory. Fenders must be as high as the tallest part of the rear tire and must support the weight of the driver. There will be a 50 lbs. pound weight allowance for fenders in DIV’s IV, V and V+ only. (See Rule #14).

DIVISIONS V & V+ #3 as it Reads Now:

DIV V3. SAFETY: All tractors must have a working safety kill switch. Ladder bars, wide front ends, and use of rev limiters is highly recommend. All DIV. V tractors will have a 3/8 inch steel plate over the flywheel and clutch housing or a an approved scatter safety blanket may be used. Steel flywheels are highly recommended.

DIV V +3. SAFETY – All tractors must have a working kill switch, wheelie bars, and engine side shields. (Side shields that are allowed – Factory equipment or made of (aluminum, lexan or steel materials). Ladder bars and wide front ends are highly recommended. Steel flywheels are also highly recommended. All DIV. V+ tractors will have a 3/8-inch steel plate over the flywheel and clutch housing and or an approved scatter safety blanket may be used. John Deere horizontal two-cylinder production tractors must have an enhanced safety shield covering over the complete flywheel. (NATPA Boards discretion). Roll bars & cages are allowed but not required.

{Add this to General Rules #11. Also add to Safety #3 in Divisions 5 and 5+}.

An approved SFI certified safety blanket is required in Divisions 5 and 5+. The installation and fastening method will secure the blanket in place to sustain fragment containment in case of an explosion.

I’ve received a lot of questions about this that we were not clear on what type of blanket to use in these two divisions and why.   -Bob DeBerg, NATPA President

 

NATPA – GENERAL RULES

As it Reads Now:

  1. SPEED CONE – Speed cone distance will be decided by the NATPA Board of Trustees. One beep after a marker, flag or cone will result in disqualification. The marker for speed will also be used as the mark to stop the tractor if driver wishes to restart pull. The puller will have two chances or two tries to move the sled. If there is no measurable success of movement after two tries, 5 points will be granted/warded for that weight class. It will be 4 the decision of the NATPA Board of Trustees to allow more than two tries due to tractor or sled malfunction and or track conditions.

Remove the 4 – It will be 4 the decision

 

The “NEW” Re-Wrote Version:

  1. DIVISION/SPEED CONE – Divisions and mile per hour (MPH), speed cone distance will be decided by the NATPA Board of Trustees. One beep or horn after a division marker, flag, or cone will result in disqualification. A 50 or 75 foot marker, flag, or cone (depending on length of track or tracks) will identify the mark you must stop at before the puller chooses to restart another attempt at their pull. If you go past the 50 or 75 foot mark your distance will be counted after that point for your pulling distance. The puller will have two chances or two tries to move the sled. If there is no measurable success of movement after two tries, 5 points will be granted/awarded for that weight class. Note: The tractor must make an attempt to hook and move the sled to earn points for that weight class. It is the decision of the NATPA Board of Trustees to allow more than two tries due to tractor or sled malfunction, and track or weather conditions.    -Bob DeBerg
