| Abstract | ||||
| A new combine header designed and fabricated set up on local combine axial flow constructed by AENRI to determine the perfect performance and decreasing both of combine losses and operation cost. The modified combine was tested under four forward speeds of 1.7, 1.9, 2.2 and 2.4 km/h, four drum speed of 12.39, 15.7, 17.01 and 18.32 m/s, and three cutting height of 5, 15 and 25 cm, respectively. The obtained results show that, the modified combine gave the best results at 1.9 Km/h forward speed, 15.7 m/s drum speed and 25 cm cutting height, where the maximum effective field capacity of 1.66 fed/h, field efficiency of 69.1%. and the maximum grain out put of 1.144 Mg/h. On the other hands, minimum energy consumed of 25.87 kW.h/fed, minimum of total losses and total grain damage of 5.41 and 0.41 % respectively are obtained. | ||||
