The aim of the present study has been concerned with a particular problem, associated with the pickup drum of the balers. That aim was seem to be achieved through developing a new design for the pickup drum, which its idea depend on using the picker chains and claw elevator chains instead of using the usual tines in the currently balers in the minister of the agriculture. This investigation carried out to study the effect of the engineering parameters of the four rotation speeds for the double job units(pickup plus elevating straw) for the proposed design, three of chassis tilt angles, three of straw feed rates and three levels of straw holder heights on the straw elevated efficiency and loss percentage for the proposed design. Also evaluate the machine performance by determining the machine field capacity and productivity. The results indicated that the best value of straw elevated quantity was 7.075 kg/min, which obtained at 102 rpm rotation speed of the combined units and straw feed rate 4 kg/min. For increasing the straw holder's heights from 0 to 2 cm increases the field capacity from 0.058 fed/h to 0.086 fed/h at decreasing the chassis tilt angles from 36 to 28 degree. Also increasing the straw holder's heights from 2 to 4 cm increases the field capacity from 0.06 to 0.096 fed/h at increasing tilt angles from 28 and 36 degree.
