ABSTRACTPaddy threshing is a labour intensive operation and mostly carried out by farm

women in bending posture. In this study, the performance of pedal operated paddythresher was evaluated with farm women and compared with traditional method i.e.,manual beating of paddy on wooden log. The mean working HR in pedal operated paddythresher was found to be 134 beats/min, whereas it was 141 beats/min by traditionalmethod.The corresponding work pulse (ÄHR) was 51beats/min. The energy expenditurerate (EER) found to be 17.7 kJ/min with the use of paddy thresher whereas traditionalmethod it was recorded as 19.3 kJ/min. It was observed that there was 20% increasein output with paddy thresher and there was 43% drudgery reduction in ODR ascompared to traditional method. Pedal operated paddy thresher is an improved andconvenient technology developed for minimizing drudgery and grain losses occurredduring threshing.
