This class will reinforce the concepts of mechanized irrigation systems acquired from the intro class. Course work will provide an in-depth and practical view of the various propulsion systems, electrical/electronic/digital logic controls and irrigation hydraulic principles. It will focus on technical service and operation aspects irrigation service technicians experience in the held. Instruction using "real-life" lab equipment under authentic conditions provides "hands on" experience similar to actual held work.

Prerequisites

IST 141; Intro to Mechanized Irrigation Applications I
Course Outcomes

Upon successful completion of the course, students should be able to demonstrate the following knowledge or skills:
