I'm a technical trainer for a Komatsu distributor in Kentucky & Indiana. Mostly, I teach our technicians but sometimes do troubleshooting classes for customers. Our territory has shovels up to the PC5500 and trucks up to 240 tons, but with the coal market going to h3ll, many of the larger machines are being parked.
