PERFORMANCE EVALUATION OF ROTAVATOR BASED ON DIFFERENT SOIL MOISTURE CONTENT

Rotary tillage implements are now being projected as important equipment that results in production of fine tilth soil. Preparation of an optimum seedbed condition by minimizing the time, cost and energy requirements has assumed considerable significance for the paddy - wheat farming sys tem widely practiced in northern part of India. In order to study the effect of various parameters on the performance under actual field conditions, a rotary tiller was selected. Moisture content (11.27%, 17.04 % and 22.87%) was recorded in the different f ield conditions. The rear shield position was adjusted at full down, full up and middle positions and three different Forward speeds of the tractor 2.5 km/hr, 3.0 km/hr and 3.5 km/hr and three types depth of cut 5cm, 8cm and 12cm. were used for the study . The study was undertaken to examine the influence of Forward speed, depth of cut at different moisture content fields with dependent parameters such as draft, fuel consumption, power consumption, field efficiency, and residue incorporation by rotavator. In this paper the results indicated that as the forward speed, shield position full down and depth of cut increases, the value of draft, fuel consumption, power consumption also increases
