Agricultural Machines and Mechanization
A.Y. 2023/2024
Learning objectives
The student will know the basic aspects of Agricultural Machines starting from the internal combustion engines functioning, to the tractor structure and functions and the basic criteria to optimize the coupling between tractors and machines. Successively, they will know the classification and the technical characteristics of the main agricultural machines as well as the criteria for their selection and rational use.
Expected learning outcomes
Knowledge of the tractor characteristics, its functioning and optimization of machines coupling; knowledge of the technical and operational characteristics concerning the main agricultural machines.

Assessment methods and Criteria
The exam is written, including calculation aspect; to this end during the course exercises are carried out aimed at solving technical problems that can be found in the operational practice and the passing of the exam. The evaluation criteria aim to verify - through a series of questions on the different topics and the resolution of specific exercises - the degree of overall knowledge acquired by the student. The evaluation, related to the entire course, is carried out in thirtieths.
