Abstract: Linseed (Linum usitatissimum L) considered the most important oil and fibber crop in the world. The manufacturing of linseed thresher was fabricated through local materials for deseeding of linseed crop. The two rollers for driving through the handle. Fabricate of manually hand operated linseed thresher is given all dimension. It is overall dimension of frame (L×W×H) cm = 50×30×100, diameter of roller (cm) = 13, length of roller (cm) = 30. The result shows that the physical properties of linseed crop was determined as average length of linseed capsule 79.4 mm, average width of linseed capsule 70.8 mm, average length of linseed 4.54 mm, & average width of linseed 2.27 mm. the result show that the machine capacity, threshing efficiency & grain damage of this thresher. The machine capacity was found maximum as 7.02 kg/h. The threshing efficiency was found maximum as 98.6%. The grain damage was found minimum as 0.9%.
