It appears farming equipment touching metal sparked a fast moving grass fire in Collin County, north of Royse City. 113 acres of blackened land sits along County Road 590.
Assistant Collin County Fire Marshal David Toler told NBC 5 that two homes were threatened for a time but were saved. No evacuations were ordered.
Huge plumes of smoke could be seen as far west as Dallas County. Gusty winds were a major factor.
"When a fires going in this type of fuel load, it runs real fast, runs real quickly," Toler said. "So it's taxing on all units responding.. trying to put this fire out."
At least ten fire departments worked together to contain and stamp out the flames.
At 4:26 p.m., NBC 5 contacted the Rockwall County Sheriff Department. It reported the fire was contained but not totally out.
