A 75-year-old Kansas man was killed when his antique tractor rolled on top of him at the Nebraska State Fair.

The Nebraska State Patrol says Charley DeWeese was trying to load his 1936 John Deere tractor onto a trailer when the accident happened Sunday morning.

The Thayer, Kan., man fell off the tractor and was pinned beneath it after the tractor’s right rear tire slipped off the ramp.

State Patrol Lt. Dennis Leonard said DeWeese took part in Saturday’s attempt to set a new record for the largest tractor parade. Fair officials say 1,139 people brought tractors to the fairgrounds in Grand Island, Neb., for the tractor parade.

DeWeese travelled to the Nebraska Fair with his wife.
