Overview

This course examines the functional requirements of the major groups of machinery and investigates the engineering principles and subsystems which underlie their operation. It develops the knowledge and skills necessary to analyse and predict machine performance, and to advise and assist farmers in the choice and efficient operation of a wide range of machinery. It also includes discussions of alternative energy resources and uses in agriculture as well as recent applications and industry developments in automation and precision agriculture. Tractor performance and testing are investigated. Tillage, planting, spraying and harvesting machinery are described and analysed. The thermodynamics of grain drying and controlled environments are also investigated. The course uses real world data sets from both field and lab work to show how the theory is related to practice.

Course learning outcomes

On completion of this course, students should be able to:

  1. understand the importance of uses of energy and renewable energy in agriculture, and their impacts on environment;
  2. describe the operating principles of internal combustion diesel engine;
  3. describe the measurement and calculations of engine PTO, and tractor drawbar performance;
  4. compare the different types of tillage implements and select the most suitable type for various purposes;
  5. compare the different types of planters and different types of spraying equipment;
  6. appraise the function of grain and other crop harvesters;
  7. describe the differences of various fans, pumps and irrigation systems;
  8. calculate basic thermodynamic properties and thermodynamic processes of grain drying, using psychrometric charts;
  9. justify the rational selection of farm machinery and the economics of farming systems.
