An accident late Tuesday morning in Greene County has claimed the life of a man who was riding on a tractor. The Iowa State Patrol says 47-year old Patrick Fields, of Paton, died at the scene of the crash when the 1965 International Tractor he was driving was hit from behind by a semi. The tractor was pushed into a ditch by the impact, and rolled on top of Fields, pinning him underneath.

The accident happened at around 11:20-a.m., as Fields was traveling east on Greene County Road E-18. The driver of the 1996 Freightliner semi, 25-year old Troy Shaw, of Harcourt, was not injured. The accident remains under investigation.

The Iowa State Patrol was assisted at the scene by deputies with the Greene County Sheriff’s Office, EMS, Paton Fire and Grand Junction Fire and Rescue.
