Energy management in farm operations is significant factor in agricultural productivity. Tillage is an energy-intensive farm operation that consumes about 40 per cent of the total energy input needed to produce crops. Data on draft and power requirements of tillage equipment is a significant factor in the selection of appropriate implement for a specific agricultural operation. As the power unit represents a significant capital outlay, it is important to have awareness of the draft and power requirement when making decisions on machinery management. The experiment was conducted in indoor soil bin in order to investigate the effect of operational parameters on draft and power requirement of selected tool. The experiments were performed by selecting locally available rigid and spring cultivator tines with reversible shovels at depth of operations of 0.08, 0.10, 0.12 and 0.14 m and forward speeds of 0.97, 1.25 and 1.53 m/s at a moisture content of about 9-10 per cent and cone index of about 1060-1160 kPa. The draft and power requirement of both rigid and spring cultivator tines was directly related with speed and depth of operation. The draft and power requirements were found increased with increase in speed and depth of operation. The spring tine resulted minimum draft and power requirement (0.39 k N and 0.5kW) of 10.26 per cent and 10 per cent than the rigid tine (0.43 kN and 0.55 kW) respectively. In order to achieve a better energy management of a tool, spring cultivator tine found more suitable compared to rigid cultivator tine.
