The effect of radius of curvature and spading frequency on various dependent variables, i.e. weighted mean clod size, soil bulk density, cone index and cone index ratio were studied. The experiments were conducted in soil having 15.7 per cent clay, 53.6 per cent silt, and 30.7 per cent sand. During experimentation, moisture content of soil was maintained between 13 and 14 per cent. The radius of curvature used were C1 (Flat), C2 (15 cm) and C3 (30 cm). Four levels of bite lengths viz., 4, 6, 8 and 10 cm at travel speed of 18.47 cm/sec were selected for the study. These corresponded to four levels of spading frequencies namely F1 (1.85 cycles/s), F2 (2.31 cycles/s), F3 (3.08 cycles/s) and F4 (4.62 cycles/s). The spading frequency was determined by dividing the travel speed by the bite length. The dependent variables decreased with increase in radius of curvature and spading frequency. Weighted mean clod size, soil bulk density and soil cone index decreased with increase in spading frequency and radius of curvature. However, it increased with increase with blade width.Keywords

A comprehensible computer program is developed in Visual Basic studio to determine the tractor parameters for an automated steering system. Tractor parameters such as real wheel and front wheel trajectory coordinates, clockwise front and rear wheel angle and corrected front and rear wheel angle can be calculated. The input parameters of the developed program are mainly front wheel trajectory data, rear wheel trajectory, distance between front and rear wheel(X13), Tractor velocity vector(V) and Tractor turning angle with center line. The tractor parameters are being calculated with the help of mathematical model which are already fed in program. The developed program successfully calculates the tractor parameters on automated steering system. This developed software could guide an autonomous agricultural tractor in the field. Furthermore, software navigates agricultural tractor both in straight or curved path at normal field operational speed.Keywords
