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.
Knowledge of the tractor characteristics, its functioning and optimization of machines coupling; knowledge of the technical and operational characteristics concerning the main agricultural machines.
GENERAL ISSUES - Soil characteristics; Force, Mechanical Energy, Power, Efficiency; Endothermic engines (Diesel and Otto cicles): characteristics values and parameters of engines; Fuelling, lubrication and cooling systems; Calculation of power and characteristic engine's curves; Transmission ratio and components. TRACTOR - Power transmission; Propulsive and supporting elements, Grip and resistance to forward movement; Towing hitches and weight bearing hitches; Dynamic engine power balance; Operational selection criteria.
