A power operated pulse reaper was developed at OUAT, Bhubaneswar and evaluated in farmer’s field for harvesting green gram. The performance of the developed reaper was studied for 3 different varieties of green gram namely OUM-11-5, PDM-54 and Local at three machine speed (, and km/h). The highest effective field capacity of ha/h was observed at km/h speed while the lowest of ha/h at km/h for the local variety. The highest field efficiency was found to be for OUM-11-5 variety at km/h speed while lowest field efficiency was for PDM-54 at the same speed of km/h. The cost of harvesting with this machine was found to be Rs 625/ha as compared to Rs 3100 /ha in traditional method of manual harvesting by using local sickle and Rs 5000/ha by manual uprooting. | Development and evaluation of a self propelled pulse reaper
