PERFORMANCE EVALUATION OF TRACTOR OPERATED GROUNDNUT THRESHER

Threshing operation is also different in India and among the developing countries. The threshing is done from the old traditional method of using sticks and racks to the modern power threshers. In India the smallholder and marginal farmers do manual threshing. After harvest bunch type plants are stacked in heaps with the pod-end exposed. The crop has remained in this state for a week. The pods are plucked from the plants with labours or threshed by power thresher. Drying the plants for a few days facilitates the threshing operation. In order to get timeliness of threshing, nowadays power thresher is mostly used for groundnut crop. Mechanization of this process removed a substantial amount of drudgery from farm labour. The working performance of tractor operated thresher was evaluated under this study.
