520 _aThe aim of the present study was to modify the stationary thresher machine to become suitable for chopping and cut farm crop residues with the desired cutting lengths from crop residues suitable for different uses. The objective of this work was to evaluate stationary thresher machine. The studied variables included: Three different feeding rates 0.5, 1 and 1.5 ton/h, three different threshing drum speeds 13.1, 15.71 and 18.33m/s, three different oval slots area were used 4, 6 and 8 cm2, three different moisture content of rice, corn and cotton were used 6.5, 10.2 and 14.3 %, three different concave clearance were used 3, 4 and 5 cm with three kinds of crop residues rice straw ,corn stalks and cotton stalks. The experiments were carried out in Bhnay village ,El-bagour center, Minofiea governorate, Egypt, during summer season of 2005. Obtained results show the stationary thresher machine can be successfully used for chopping and cut under the following condition: oval The slots area of 4cm2, drum speeds of 18.33 m/s, feeding rates of 1.5 ton/h, moisture content of 14.3 % and concave clearance of 3 cm resulting in cutting length percentage of 82.1,85.6 and 80.1% less than 3.5 cm for rice straw ,corn stalks and cotton stalks respectively. Power consumption and energy requirement were found to be (43.4,40.3 and 38.7 kW) and (28.9,27.3 and 25.8 kW.h/ ton) for rice straw ,corn stalks and cotton stalks. The maximum operation cost was 25 LE/h and 17 LE/ton for rice straw.
