Abstract:
The present investigation was carried out to study design and development of mini tractor operated Wavy disc PTO powered tillage implement in the year 2014-15.A PTO powered wavy disc type tillage implement with four numbers of wavy discs of 43 cm was designed and developed for tillage operation and tested in field condition to evaluate its performance. A wavy disc type tillage implement consisting of wavy discs, frame, depth control wheels and power transmission system was developed. The performance of the developed implement was assessed by varying three different parameters - gang angle (20°, 25°, 30°), forward speeds (0.35, 0.77, 1.19 m/s) and depth of operation (4, 8, 12 cm) and performance was observed in terms of mean mass soil diameter, draft, fuel consumption, wheel slip and field capacity. Performance analysis of the implement was carried out with Response Surface Methodology. Statistical significance of the terms was examined by analysis of variance (ANOVA) for each response using face centered central composite design. The average values of mean mass diameter, draft, fuel consumption, wheel slip and EFC obtained during the experiments were 12.28 mm, 106.12 KGF, 11.65 l/ha, 7.27 % and 0.178 ha/h, respectively. The overall best results for the developed tillage implement were obtained at 25° gang angle with forward speed of 0.77 m/s and depth of operation as 8 cm.
