Partridge ? A hayrack ride in central Kansas turned deadly when children fell off the small tractor and were run over, killing one and injuring three others.

Reno County authorities said a 12-year-old died Sunday afternoon at the scene of the accident northeast of Partridge. The victim’s name was not released.

Reno County Undersheriff Sheldon Stewart says three other youths were injured when they fell off the front-end bucket of the tractor.

Stewart says the four children were riding in the loader on the front of the tractor when they fell off and were run over by the tractor. Three other youths were in a hayrack being pulled by the tractor and a young child was sitting on the driver’s lap. They were not injured.

The Hutchinson News reports that Stewart says the cause of the accident has not been determined.
