Agricultural machinery

A.Y. 2020/2021
Overall hours
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.
Course syllabus and organization

Single session

Lesson period
Second semester
In case of Covid emergency measures, the course will be go through possible changes.

Contents and teching material - The course contents and reference material remain unchanged.
Teaching methods - Lectures will mostly be held in remote on MS-Teams. The lectures recordings will be available to students (links in Ariel). Additionally, there will be some classroom meetings in attendance for introduction and discussions of course topics. The attendance must be booked through the app LezioniUnimi.
Exams - The exam remains unchanged except for being held in remote ( and MS-Teams plataforms). Specific instructions are available at Ariel web page of the course.
Course syllabus
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
Knowledge of the basic mechanical and physical quantitities and units, and as well of the main processes of agricultural production
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.
Field activity: 8 hours
Practicals: 24 hours
Lessons: 32 hours
