Small landholders cannot afford to buy tractor as well as maintenance of bullocks has become very costly particularly when they are not in use. By using the multipurpose power unit the small and medium farmers can avoid the year round maintenance of bullocks and also the high investment in tractors. The multipurpose tillage tool carrier (MPTC) developed and tested along with ploughing (primary tillage) and leveling (secondary tillage). The performance evaluation of tillage tools i.e. Mouldboard plough and horizontal blade were done with MPTC with the help of 5 hp (3.7 kW) power unit. The experiments were conducted with three moisture content 6.6, 12 and 20% db. The tool carrier designed for attachment of plough and horizontal blade is found suitable for tillage operation due to its simple design. There was ability to adjust width of cut, depth of cut, row spacing with little adjustment. The developed MPTC has proper matching ability with the selected 3.7 kW power unit. The developed unit evaluated for field efficiency (%), unit draft (N/cm2), power requirement (kW), energy requirement (kWh/ha), performance index (%), fuel consumption (lit/ha), field capacity (ha/h), soil pulverization (mm) and cone index (kPa) at different moisture content (6.6%, 12% and 20%). The utilization of power during the operation of MPTC with m.b. plough and blade were 0.8 and 0.5 kW respectively. The average field capacity was 0.20, 0.21ha/h, field efficiency were 86.6 and 89.1% and Energy requirement and soil pulverization were 3.3, 2.9 Kwh/ha and 12.1,3.3 mm respectively at 20% moisture content of soil with 2.5 km/h speed. The experiment result show that m.b. plough performed satisfactory at 20% moisture content as primary tillage tool. The developed m.b. plough is a low cost implement and may be proved as very useful to the small farmers.
