Field experiments were carried out during the agricultural seasons of 2007 and 2008 at Kafr El-Hamam farm, Sharkia governorate to investigate the response of two rice varieties (Sakha-101 and Giza-178) to mechanical harvesting using two combine harvesters (Yanmar and Claas) at four average forward speeds of 0.5, 1.2 , 1.9 and 3.1 km/h and four average grain moisture contents of 15, 18, 21 and 25%. The results obtained reveal that, the minimum total grain losses were 2.70 and 3.9%; 2.76 and 3.0% at average grain moisture content of 15% and forward speed of about 1.2 km/h, using Yanmar and Claas combines to harvest rice crop (Sakha-101 and Giza-178) varieties respectively. The maximum field capacity values were 0.97and 2.72 fed/h ; 0.94 and 2.60 fed/h at average grain moisture content of 15% and forward speed of about 3.1 km/h, using Yanmar and Claas combines to harvest rice crop (Sakha-101 and Giza-178) varieties, respectively. The maximum cutting efficiencies (%) and the minimum specific energy consumed values (kW.h/fed) were (92.7 and 93.7 % ; 91.6 and 90.5 %) and (14.62 and 8.45 kW.h/fed ; 21.26 and 9.38 kW.h/fed) at average grain moisture content of 15% and forward speed of about 0.5 km/h, using Yanmar and Claas combines to harvest rice crop (Sakha-101 and Giza-178) varieties, respectively. The minimum criterion cost values for harvesting both rice crop varieties (Sakha-101 and Giza-178) were 263.00 and 331.60 L.E/fed ; 236.6 and 251.8 L.E/fed at average grain moisture content of 15% and forward speed of about 0.5 km/h, using Yanmar and Claas combines to harvest rice crop (Sakha-101 and Giza-178) varieties, respectively.
