Agricultural Machinery
A.Y. 2023/2024
Learning objectives
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.

Prerequisites for admission
Knowledge of the basic physical-mechanical quantities and their units of measurement, as well as a knowledge of the most important cultural operations related to major agricultural productions.
Teaching methods
Lectures (4 CFU). Numerical applications and examples (1,5 CFU). Technical visits (0,5 CFU).
Teaching Resources
Bodria, Pellizzi, Piccarolo- Meccanica e meccanizzazione agricola (Edagricole). Fiala - Esercizi di meccanica agraria (Ed. CUSL).
Assessment 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.
