Groundnut is an important oil seed crop in India cultivated in an area of 6.7 million hectares with a production of 7.0 million tonnes annually. The crop can be grown successfully in areas receiving the rainfall ranging from 600 to 1250 mm. The best soils for groundnut crop are sandy loam, loam and medium black with good drainage system. Present practice of manual harvesting and threshing consumes huge amount of labour to a magnitude of about 175 to 200 women h ha-1The highest average effective field capacity obtained using tractor drawn groundnut digger shaker was 0.35 ha h-1. The highest average field efficiency of 80.10% recorded for tractor drawn groundnut digger shaker at a soil moisture content of 12%. The low values obtained for both average effective field capacity and field efficiency of the tractor drawn groundnut digger shaker as a result of the turning and other miscellaneous losses. The haulm yield of the windrows formed for a harvested distance of 10m was 1.011 kg for single row,2.128 kg for two rows and 3.518kg for three rows. Performance of wetpod thresher selected for a design was observed at feed rate of 870 kg h-1 and the thresher output was 227.25 kg h-1 with the total number of labourer of 6. Similarly in case of manual stripping output was only 51.13 kg h-1with the equal number of labourer. Therefore, it was found that output capacity of selected thresher was 4 times more than the manual stripping with equal number of labour requirement.
