Wisconsin Tractor Pullers Association (WTPA) was first organized in April of 1970 during the first official meeting in Stroughton, WI. It was announced at this meeting that there would be a test pull at Lloyd Luedtke's home using his sled on May 31, 1970. This test pull would officially start the 1st pulling season of WTPA.

It all started in 1989, when a 19-year-old kid with a passion for fire safety sold his first fire extinguisher. Today, that kid, firefighter Allen Kronebusch, runs AKE Safety Equipment, the only firefighter owned, operated, and endorsed fire safety company and fire extinguisher manufacturer in the country. AKE STOP-FYRE®, official Fire Extinguisher of the NTPA.
