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%. | Studies on harvesting and threshing parameters of available tractor operated groundnut digger-shaker and fresh pod thresher
