Retired truck driver Bud Grose of Glenrock told The Associated Press in a telephone interview on Wednesday that he has a heart condition but didn't require any medical attention.
Investigators say police in Glenrock used a Taser on the man after he disobeyed orders. They say the tractor may have hit a car.
Two officers were placed on paid leave and state agents are investigating, but the police chief says it doesn't appear any policies were violated.
Grose wouldn't discuss specifics of the incident until he speaks to his attorney.
