| Abstract | ||||
| The aim of this work is to develop and construct attachments to the combine harvester to directly obtain fine chaff suitable for animal feeding. The auxiliary parts attached o the combine for chaff may maximize combine exploitation. The combine with attachments was tested at different operating conditions, at rotor speed (16.8, 20.4 and 24 m/s), cylinder concave clearance ratio between front and rear holes (0.4, 0.52, 0.64 and 0.76). Suction fan speeds (1000, 1250 and 1450 rpm) were also tested. The result show that optimum rotor speed was 24 m/s, concave clearance ratio 0.4 and suction fan speed 1450 rpm respectively. At these variable levels, the straw fineness was maximized. The development of obtaining chaff directly from combine saves time, effort and minimizes combine operation cost. | ||||
