Tractor Pull in Dennison today. Later in the day there was an issue with the sled unhooking from a puller. While the sled operator and several others were working on getting the puller unhooked the blade tractor operator stopped to the side and behind the sled. The sled operator got back in and started backing to return to the starting line, one of the sleds rear tires drove over the corner of the blade of the blade tractor blowing out the tire on the sled. The sled operator got out and threw a temper tantrum for the whole crowd to witness. He used ALOT of curse words with a loud voice over and over. He also screamed at the blade operator, blaming everything on him. A large crowd was on hand, many with small children in attendance. A very unfortunate and uncomfortable situation.
