| dc.description.abstract | A wheat straw harvester was refined for chopping of paddy straw by replacing blower arrangement with two bruising cylinders and a concave. Knife guards of the cutter bar were removed and V-shaped serrated blades were fixed below cutting blades. The developed machine was operated at 2 levels of straw loads (6.25 t ha-1 and 8.58 t ha-1), 3 levels of cylinder speeds (640, 725 and 810 rpm) and 3 levels of forward speeds (2, 2.5 and 3.5 km h1). The percentage of chopped straw of size up to 12.5 cm, the weighted mean size of the chopped straw, mulch thickness and coefficient of variation of the uniformity of straw spread were in range of 71.29% to 86.40%, 5.76 cm to 8.12 cm, 5.17 cm to 6 cm and 20.29% to 22.17%, respectively under all the treatment combinations. The fuel consumption and field capacity of the machine were in range of 11.35 to 19.47 l ha-1 and 0.27 to 0.55 ha h-1, respectively. The treatment C3F1 (810 rpm and 2 km h-1) and C3F2 (810 rpm and 2.5 km h-1) at both straw loads gave better results in case of percentage distribution of chopped straw of size up to 12.5 cm and weighted mean size of chopped straw but the fuel consumption (l ha-1) in case of C3F2 was less as compared to C3F1. The percentage of the chopped straw of size up to 12.5 cm of refined machine was lower than the existed double cylinder paddy straw chopper and weighted mean size was higher. Fuel consumption of the refined machine was lower and field capacity was higher than an existed double cylinder paddy straw chopper. | en_US |
