All of the SEATs planes I've seen in Colorado and Wyoming are the Air Tractors with the turbine engines.

After working on aircraft in the Air Force for 21 years I couldn't imagine trying to fly a SEATs with a recip
engine into the mountainous areas. That would definately create a big "pucker" factor.

Correct. They're used in lower elevation areas and flatland if at all. Up here, you need the ponies. And even then, you better know what you're doing.
Mountain + Airplane, Airplane always loses.
Some are Pilatus and not Air Tractor out West here. Newer tech, same general idea and configuration.
Some really nice photos of just about everything that flies out of the base at Metro over on the Colorado Aviation Photographers group on Facebook, for those who like such things. Both the local SEATs and the various heavies that visit.
