Study Guide

Objective

The student is able to explain in practice, theoretically and with the help of physics problem solving skills, the key features of the engine, engine progression, ground compaction, traction and the traction power of the tractor and motorized machines. The student will also be able to explain the basic structures and key features of the hydraulic and electrical systems and controls required for tractors and machines. They are able to calculate the key qualities and attributes associated with them.
The student is able to explain new trends of agrotechnology, for example in fuels.
The student will be able to present the key combustion-based heating technologies, heat pump technology, wind energy and solar energy suitable for a farm and be able to utilize an energy plan for a farm. The student is able to calculate the power, energy and efficiency characteristics of key energy forms.
