Measurement of performance parameters: The mature dried crop which was harvested 15-20 days prior to threshing was manually fed into the thresher. Bundles of 10 kg were formed and upper part (bearing pods) of these 10 kg bundles were fed to the thresher for the respective time period and lower portion was withdrawn thereafter. The output of these tests were noted and expressed in kg/h. The samples were taken from grain outlet for determining the per cent un-threshed, broken percentage and cleanliness of the grains. Sieve over-flow was collected and re-threshed at the end of experimentation. The straw was also collected for one minute from aspirator outlets and the grain recovered from this outlet was termed as noncollectable loss. The un-threshed grains from grain outlet were separated, weighed and expressed as threshing efficiency. The unwanted material from clean grains was separated, weighted and expressed as cleaning efficiency.
