Dispatched for an out of control grass fire. Upon arrival, a fire is noted along a ditch in the agricultural field that is being attended the owner. The owner advised us that they requested a fire department response as the owner was becoming tired and the fire was advancing towards a wooded area. Mutual aid with grass fire trucks from North Webster Fire Department and Benton Township Fire Department is requested as our grass fire truck is currently out of service for repair. The fire is extinguished prior to any extension into the wooded area. All units cleared the scene and returned to quarters.
