Rationale:
To effectively manage and produce from Agriculture one needs Power. Today, the agricultural sector faces sever labour shortages. To overcome these problems the use of mechanical power is essential. One who studies agricultural engineering must know the intricacies of mechanical power source namely Tractor.
Objectives:
- To study and understand various components of a tractor
- To know about diesel engine and power transmission system.
- To study fuel-air intake system
- To study the cooling system of IC engine.
- To study Lubrication system
- To study Braking and Hydraulic System.
