FAIRFIELD, Neb. (AP) — Firefighters from several departments have been called in to battle a blaze at a farm implement dealership in the south-central Nebraska town of Fairfield.

Authorities say the fire broke out early Tuesday morning at Oregon Trail Equipment. No injuries have been reported.

The blaze damaged the dealership’s main building, which contains an office and maintenance shop. The Nebraska State Patrol blocked off parts of Nebraska Highway 74 so emergency vehicles could reach the scene.

Investigators with the State Fire Marshal’s Office are trying to find out what caused the fire.
