1.PROBLEM DEFINATION

NEED STATEMENT:

THRESHER MACHINE

A farmer used to separate the grains by sieving and filtration method which would take lot of time and many labourers.Due to increasing demand of population ,the farmer wishes to have a semiautomatic thresher machine which is capable of thresing the grains out of bulk of husk.
