Heavy Equipment Service Engineering Technology is the only four-year program of its kind in the nation. Heavy equipment technicians keep diesel and gasoline-powered equipment functioning in moving freight, earth and people; pumping water for irrigation; drilling for oil; powering farm tractors; and generating electrical power. Graduates of the program diagnose malfunctions and repair engines, fuel injection systems, electrical and electronic systems, hydraulic systems, brakes, steering systems and power transmission systems. They identify problems through measurement and observation, interpret data collected and decide on a course of action.
