Description: Modern tillage practice is moving from slower to faster speed and smaller to very large in size. Because of higher speed and large machine size agricultural power requirement has increased significantly. In order to accommodate the new tillage machines within current tractor power capacity, new tillage implements are designed in different forms with conventional tillage. High speed disc tillage implements are operating at shallower depths and the discs are arranged with a gang and pitch (rake) angles to get better residue management and adequate soil disturbance in the fields. Draft force requirement for high speed disc tillage implements is not well established yet. It has become essential to determine the power requirement of high speed disc implements. In this study, draft force required for an individually mounted disc will be measured in a laboratory soil bin. Test will be conducted for dry soil with two different depths and soil compaction levels. Measured draft will be compared with ASABE standard and other empirical equations developed for draft force calculations. Variation with other standard formula will be useful as current ASABE standard and other empirical equations do not include the pitch (rake) angle for draft force prediction. A PFC3D model will be developed to simulate the draft force for new tillage equipment. Model will be used to optimize power requirement for different gang and pitch (rake) angle arrangements for best soil cutting performance.
