Goal of the course is the understanding of the fundamental principle upon which the operation of agricultural tractors, implements and plants normally used in agricultural processes are based.
Expected learning outcomes
Knowledge of the characteristics of modern agricultural tractors and farm machinery used in today agriculture. Criteria for the technical evaluation of their performances and methods for the optimisation of their technical and economic management.
Lesson period: Second semester
(In case of multiple editions, please check the period, as it may vary)
Basic concepts and laws of mechanics. Work, energy and power. Efficiency. Diesel engine. Torque-speed and power-speed curves. Exhaust treatments. Types and function of tractors. Frame structure. Power transmission. Tires and traction. Hitching systems. Tractor useful power. Technical management of tractors. Farm machinery. Type, operational characteristics and managing criteria of machinery for: soil tillage, fertiliser distribution, crop planting, crop protection, hay and forage harvesting, grain harvesting. Basics of equipment selection and costs analysis.
Prerequisites for admission
An appropriate knowledge of basic mechanical and physical principles is required, as well as of the main process of agricultural production
Bodria, Pellizzi, Piccarolo- Meccanica e meccanizzazione agricola (Edagricole). Fiala - Esercizi di meccanica agraria (Ed. CUSL).
Assessement methods and criteria
The exam has a written and an oral part. The final grade is the average evaluation of both the two parts. The written part aims at evaluating the knowledge about practical aspects and proper selection of agricultural machinery, It consists of numerical exercises with similar contents to the examples solved in classroom. The students who pass the tests during the lessons can directly access to the oral exam. The oral part consists of a discussion of the theory aspects covered during lectures.
