Design and development of manually operated harvester for wheat crop

This machine is to help small-scale farmers to meet an increased demand for local grains, by designing a harvester machine to harvest grains more efficiently. Our research work will focusing on ease of harvesting operation to the small land holders for harvesting wheat crop in less time and at low cost. The machine includes handle, main frame, cutter bar, crop divider and lifter, star wheel, ground wheel and supporting wheel. Cutter bar operated directly by ground wheel power. The optimum forward speed of the machine to obtain maximum field capacity was 1.7 km/h. the effective field capacity of the machine was found to be 0.048 ha/h. the field efficiency was 71.2 %.
