AGM 151: Drivetrains I

Credits 6 Lecture Hours 44 Lab Hours 44
In this course students will learn how power is transferred from engine to ground and PTO in various agricultural drive systems. Additionally, students will learn how torque is amplified, and how power transfer is adjusted. These principles will be first taught in the classroom and then demonstrated in a lab providing students with a both theoretical, and hands-on, learning experience in the safe operation of drivetrain systems.
