Abstract
A new machine prototype fabricated used in harvesting sugar beets was manufactured and tested to evaluated the perfect suitable performance under Egyptian conditions. The investigated harvester of the present study is a combine machine made from local materials to perform the topping, digging, lifting and uprooting collecting operations of sugar beet roots in one process. The prototype was evaluated in terms of effective field capacity (Fed/h), lifting efficiency (%), topping efficiency (%) and harvesting efficiency, (%). In addition, specific fuel consumption (l/kW.h) and total harvesting cost (LE/fed) were determined. The test experiment parameters were carried out at four forward speeds of 2.16, 2.88, 3.66 and 4.32 Km/h and four topping knife speeds of 3.1, 4.3, 5.5 and 6.2 m/s with three soil moisture content of 30, 24 and 18 % (w.b.). Results of the tests indicated that , maximum effective field capacity was 0.48 fed/h, maximum harvesting efficiency was 88.9 % , maximum topping efficiency was 97.9% and maximum uprooting efficiency was 92.6% On the other hand, a minimum of specific fuel consumption and total operation cost were 0.517 l/ kW.h and 73 L.E /fed, respectively..
