Abstract

                                The usual methed of threshing paddy is by trampling the harvested crop by animal or by beating. Both these methods have the disadvantage of requiring much time and labour. Further, grains may often be broken of, some of them not threshed out or otherwise lost. The grains also become dirty by contact with the ground. Further it is difficult to thresh the non-shedding variety. The drawbacks could be easily overcome with the use of the paddy thresher. Hence the work of improving the existing paddy thresher was taken up and on perfection the work of mechanising the same was also initiated in the Research Engineering Workshop attached to Agricultural College and Research Institute, Coimbatore-3, in order to reduce the labour and to increase the outturn.
