Schweitzer ag cat pilot reported engine failure in flight. Reporter declared an emergency and landed...

Narrative:

I was operating a garrett turbine powered schweizer G-164B ag cat with FAA part 137 operations. I was ferrying the aircraft at 500 AGL back to the home airport. I was 45 minutes into my one hour planned flight as I noticeably lost most power. I examined the torque gauge that went from '42' to '28' immediately (28 is at the bottom of the green arc for power). The torque gauge remained there for roughly 20 seconds then all power was lost. My engine RPM stayed at 100% throughout the whole dropping of the torque. I declared an emergency and found a road with no power lines or vehicles and landed. Rolling into the ditch I jumped out to find the wings had got into the ground and were slightly bent on the ends and the propeller blades were bent. The airframe was not effected and there were no chemicals on board. The police arrived immediately along with ambulance and fire trucks. There were no injuries to myself or anyone else and no property damage. The FAA was notified immediately after the incident.
