| Abstract | ||||
| Field experiments were carried out at sakha Agri. Res. Station using a developed sugar beet harvesting digger- type of SAMAKA (after modification) to study the effect of forward speed of 1.2, 1.7, 2.3 and 2.8 km/h, topping knife speed of 2.71, 3.41 and 4.14 m/s, digging depth of 0.20, 0.25 and 0.30 m and soil moisture content of 24.5, 20.8 and 17.6 % on field capacity and efficiency, topping efficiency, lifting efficiency and total damaged roots. And also, determination of specific fuel consumption and cost of sugar beet harvesting were done. The results indicated that, maximum of topping efficiency and lifting efficiency were 97.83%and 95.7% respectively. Also , the maximum field capacity of machine was 1.00 Fed/h and field efficiency was 93.8% , On the other hand, a minimum of total damaged roots , specific fuel consumption and cost harvest were 2.81%, o.386 l/kW.h and 31.54 L.E /Fed , respectively. Finally, the performance characteristics of machine were influenced by the investigated variables. | ||||
