It all began before the 1970s – but in 1970 a large group of pullers from across the state got together to start the association. They had their work cut out for them. They had to decide what (and how many classes) to run, rules for the classes, purse payout, and other areas of the association too numerous to list.
They first started out with the Super Stock tractor classes and Hot Rod or Modified tractor classes. They basically set their rules back then on a mile-per-hour basis on the vehicles. The maximum allowed was 7 MPH (wow, things have changed!). They basically set their rules in accordance with the National Tractor Pullers Association.
