MEMBERSHIP
There is not a membership fee to be a part of Lumber River Pulling Club if you meet certain criteria. To qualify for membership, you must attend a minimum of six (6) point’s pulls in the current year. This will allow you to pull for points for trophies awarded at the end of the season and attend our banquet. If you choose to pay for a membership, the fee will be $40.00.
Points for members will be awarded according to the results from the second round of pulling. The first round is qualifying and decides the pulling order of the second round. You must pull both rounds to receive points. Trophies or gifts will be awarded in the kid’s class at every pull and the kids who are members will still receive points to compete for the big trophies at the end of the season.
Optional lease parking is available to obtain a parking spot for the season if you want a particular spot. The spot you pick will be $25.00 and you can mark that spot with your name.
Membership (points) goes with the driver. If the tractor is sold, points stay with the driver, not the tractor. The driver can keep his points as long as he stays in the same class.
Members need to register their tractor at the time of the event to receive points, but they are not required to make the pull. They may sign up another driver to make any pull for them and still receive their points as long as they are present.
POINTS SYSTEM
Points go to the owner of the tractor.The tractor you start with at the beginning of the season must be the one you compete with in that class for the season, unless the tractor is sold.
You will only acquire points for the class your tractor is pulling in. You may pull up in a higher class for fun but not for points.
If your tractor breaks down in the first round, you can use another tractor one (1) or more classes down. The only exception will be the 10/12 class, which can run another 10/12 or kid’s class tractor. This allows you to keep up your points however you can only use your “backup” tractor for two consecutive pulls. This starts the night of breakage as being the first pull. This gives more than enough time to make necessary repairs.
If the same driver pulls more than one tractor in a class at a trophy pull only the higher placing tractor will be awarded a trophy.
Points will be awarded as follows: First place - 10 pts, Second place - 9 pts, Third place - 8 pts, Fourth place – 7 pts, Fifth place – 6 pts, Sixth place – 5 pts, Seventh place – 4 pts, Eighth place – 3 pts, Ninth place – 2 pts, Tenth place – 1 pt
Each class will receive trophies at the end of the season for 1st, 2nd and 3rd places.

CLASSES: Jumping up to the next class is allowed. You cannot go down a class. (This simply means you can pull in a higher hp class than your tractor but cannot pull in any lower hp class than your tractor)

The puller must then take the distance of the second pull.
SLED CHANGE: On the final round if the first 3 tractors in any given class make a full pull, track officials can make the decision to change the sled weight and or gearing and start that class over. These 3 tractors that made the full pull will have the individual option to re-hook then in the same order or to fall to the end of the lineup in that class. All 3 tractors do not have to do the same option. Track officials have the option to change the sled and start a class over at their discretion for full pulls or short pulls.
SCALES: The club will provide scales to weigh your pulling tractor. ALL pullers weigh in for their class. All weight classes are the total weight of the tractor, weights, driver and helmet. NO MORE THAN 5 LBS OVER IS ALLOWED for the weight class that you are pulling in. IF you cannot get your weight low enough to pull in that class, then the other pullers will be asked to bring their weight up to match yours to allow you to pull. (For example -1000 lbs. class and their weight is 1025 lbs.Then the other pullers will bring their weight to 1025 lbs. to allow them to pull.)
