The decrease of rural population has increased in the recent past which led to feed the growing urban population, for which there is a need to increase the productivity of agriculture has become an essential feature in stepping towards sustainability. Presently, the untilled soil near the bunds and corners of the field are prepared manually which is consuming more time and energy. More over manually made bunds not properly aligned and compacted, and not last for long causing rodent problem. The performance of tractor drawn ridge plastering machine was evaluated in the field conditions at FIM, Scheme, Rajendranagar, Hyderabad,Telangana in sandy loam soil with a moisture content of 13.87 % (db). The machine can be operated with 40-70 hp tractors. The attachment weighs about 390 kg with 1.62 m length, 1.66 m width and 1.13 m height. The hydraulic power of the tractor is used to change the direction of operation. The machine has an eight-tyne rotavator, a leveller, a rotating disc of 700 mm diameter and a 20 mm long roller. The rotavator pulverises the soil, the leveller levels the soil, and the rotating disc trims the bund and plasters it with pulverised soil. The roller attached to the rotating disc compresses the soil. During the field study it was observed that, the field capacity of the machine was 1000 m per hour at an average speed of 1.0 km//h with the height and width of bund was 25 cm and 45 cm respectively. The angle between ground and the side wall of the bund is 1200. The fuel consumption of the machine was 4 l/h. The cost of operation of the machine observed was Rs. 712/hr. The cost saving was Rs.2248/- over conventional method. This technology will save the energy and time involved in field preparation. It will reduce the drudgery and labour. it also reduces the rodent problem due to clean, straight and plastering type compacted bunds when cut with the rotary plough for bund side cutting.
