Preliminary Analysis of Interaction Among Gears, Tines and Soil In a Rotary Harrow

This study concerns the preliminary analysis of a rotary harrow. It is analysed both from a kinematic and a structural point of view. The analysis focuses particularly on the force exchanged between the tine and the soil, drawing on scientific literature relating to the subject. Based on this force, a structural analysis is therefore carried out on the harrow tine and there is an analysis of the forces acting on the rotors connected to the tines. By creating parametric spreadsheets, it aims to outline a future method of study which will enable various geometries of harrows to be analysed quickly under different work conditions. The preliminary results obtained are satisfactory with reference to the resistance tests of the elements analysed and useful for the future study of the implement.
