Agricultural Machines and Mechanization
A.Y. 2022/2023
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.

Lesson period
Second semester
The teaching program does not change, as well as the reference material. Teaching is delivered remotely in synchronous mode, with the help of the MSTeams platform, following the timetables defined by the Didactic Secretariat. The methods for verifying learning and the related assessment criteria remain unchanged.

Assessment methods and Criteria
The exams are oral, including calculation aspect; the use of calculators is therefore permitted. 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, related to the entire course, is carried out in thirtieths.
