Abstract
Compost turning machine was designed, modified and fabricated locally. The large number of field testes run by the turner proved that the machine was well designed and reliable. According the machine was field operated for several seasons in turning compost windrows at variable conditions with recognized turning efficiency. The experiments showed that the double drums machine turned the compost windrows pile with high quality. The local fabricated compost turner is powered by two power systems. The first is mechanical system and the second is hydraulic system. The mechanical system is to rotate the double augers drums path by tractor PTO. The hydraulic system is to push the machine and tractor to the front path by hydraulic power from the tractor. The objectives of this study were to optimize power source requirement for the locally fabricated compost turner as follow:-

Analysis of theoretical parameters that affect both rotating augers and forward motion of turner.
Determine actual vs measured power required for the turner.

The power requirements were calculated to defy the actual power consumption to be suitable and safe for machine. The maximum power was 45 kW and the minimum was 8 Kw. From design calculation of the main parts in the hydraulic system, the maximum diameter of the cylinder piston is 90 mm to raise and lower the turner box with double drums. Anther side of the two cylinder piston to lower and raise the machine during transportation is 90 mm also. Theoretical hydraulic motor power which is satisfactory to drive the system (turner and tractor) was calculated and the proper motor size was selected.
