Participate as an Exhibitor

The main exhibitor areas at the Old Threshers Reunion are the traction steam engine, gas engine, tractor, horse, and car & truck areas. All of the areas have different criteria for new exhibitors to follow if they wish to display or demonstrate at the annual event.

Traction Steam Engines:

Both full-sized and model traction steam engines are exhibited at the Reunion. All traction steam engines (including model engines) will be inspected by our safety committee and must pass all of the inspection requirements to be exhibited at the Old Threshers Reunion. 

If you have any questions, contact the Old Threshers office to be put in contact with the area directors who will personally answer your questions.

Gas Engines:

 The majority of the gas engines displayed at the Reunion are antique, exposed flywheel gas engines. The engines must be in restored and operable condition and the exhibitor is encouraged to operate the engine during the day. Most gas engine exhibitors simply bring their engines to the Old Threshers Reunion and register at the Gas Engine Headquarters.

Tractors:

 All tractors exhibited at the Old Threshers Reunion must be 1965 or older and should be in operable condition. Each year, a tractor manufacturer is featured. If your tractor was manufactured by the featured company, we allow newer than 1965 if it is in the middle of a production run. Most tractor exhibitors simply bring their tractors to the Old Threshers Reunion and register at Tractor Headquarters.
