HARDIN COUNTY, Ill. (WAND) - Illinois State Police say one man is dead after a truck-tractor dump trailer and farm tractor collided on Illinois Route 34 Thursday morning.

ISP officials say the crash happened at the intersection of Illinois Route 34 and Dutton Chapel Road in Hardin County at about 9:37 a.m.  According to the preliminary investigation into the crash, a farm tractor, pulling a rotary mower, was traveling north on IL-34, with a Freightliner truck-tractor dump trailer traveling behind.

The investigation into the crash is ongoing.
