Antique tractor pulling is how tractor pulling first got started. As early as 1929, farmers began attaching their tractors to drags, and dragging it down a field to see who could pull it the furthest. People who were event organizers at Bowling Green, Missouri and Vaughansville, Ohio found out farmers were doing this and that it drew spectators. By 1950, county fairs across the country started featuring tractor pulls. Spectators found it fascinating to see machines that would “Pull on Sunday, plow on Monday”. At first competitors would use a ‘Human Drag’, meaning a drag that was weighted by humans, different people would be added as the tractor made it down the track. However, organizers began to look at different ways to add weight to the drag, as spectators walking on the drag while moving proved to be a hazard. In the late 60s, a weight-exchanging drag was created, the drag that was created was basically a flatbed truck trailer with wheels near the back and a drag at the front. A mass that is moveable of up to 65,000 pounds or 29,000 kilograms, the mass starts at the back of the sled, slowly working its way up to the top as the drag moves down the track.
