PREDICT TRACTOR DRAWBAR FORCE FOR PRIMARY TILLAGE IMPLEMENTS

The effect of soil moisture content and tire inflation pressure on tractor performance was determined when linked to moldboard and chisel ploughs as primary tillage implements. The factors considered were fuel consumption, tire inflation pressure, tillage width, tillage depth, dynamic load and speed of operation and cone index of soil. By conducting the experiments in the field, relations were developed between different independent variables and one dependent variable i.e. drawbar pull for moldboard and chisel ploughs. A model for predicting drawbar pull for chisel and moldboard ploughs was developed and tested
