STEARNS COUNTY - Authorities say a Melrose man died when he was trapped underneath a tractor.

The Stearns County Sheriff's Office says they were called to a farm at 30,000 block 390th Street in Millwood Township (northeast of Melrose) just after 11:20 a.m. on Wednesday.

Deputies arrived to find 65-year-old Donald Hinnenkamp of Melrose partially entangled in a hay merger. He was pronounced dead at the scene. Authorities say it appears Hinnenkamp had a medical issue and was able to put the tractor in neutral.

An autopsy will be done by the Ramsey County Medical Examiners Office. The incident remains under investigation by the Sheriff's Office.

Freeport Fire and Rescue, Melrose Fire and Rescue, Melrose Ambulance and Lifelink Air Ambulance all responded and helped the Stearns County Sheriff's Department at the scene.
