The irrigation operation requires higher energy to utilize tractor power to operate the pump. The present study entitled “Design and Development of Tractor Operated Irrigation System” was carried out to make available design suitable for the tractor PTO operated advance irrigation system. M&M make Sactor (Shaan) tractor was used to develop the irrigation system. The said system is useful in case of delayed monsoon as it enables to give life saving irrigation. The raingun was used to apply irrigation water to the crop. Computer Aided Design was used to design various assemblies of the system which included the irrigation water tank, Toe hook, rolling wheel etc. and its manufacturing drawing. The laboratory testing of the irrigation system was carried out using different nozzle sizes of the raingun at different pressure levels. The discharge and the radius of throw were determined for different nozzle sizes at different pressures. The nozzles of 6, 8, 10 and 12 mm Ø were selected for the present study. The raingun at the pressure of 6 kg/cm2 gave a discharge of 3.12 lps. At the pressure of 6 kg/cm2, radius of throw of raingun was 26.30 m which covered an area of 0.25 ha in a single rotation. Results of the study indicated that the pressurized irrigation system covered the area of 0.25 ha in a single rotation of the sprinkler head of the raingun. The duration for the irrigation using the advance irrigation system was found to be less. Tractor PTO power was used as the source of power which facilitated the mobility of the system in to the field.ennullThesis
