This study was carried out at a private farm in Owlad Sakr District, El-Sharkia governorate Egypt during 2016 summer season. Wheat Misr 1 variety was harvested using a modified self-propelled reaper-binder. The modification was assembling a conveyor mat to facilitate the harvested material failling down upon the soil surface. The experiment was established and designed statistically as a factorial experiment with three replications. the tested treatments were mat linear speed (0.09, 0.10, 0.11

The results indicated that 0.09 m/s mat linear speed accompanied with 10° mat oblique angle accomplished higher machinery productivity of 3.55 Mg grains/h and 3.61 Mg straw/h,lower specific energy requirements of 26.43 MJ/Mg, lower conveying losses of 5% grains and 4.8% straw and lower operational costs of 891 LE/mg. So, it is recommended to apply the modified reaper-binder to harvest and bind for wheat and other grain crops.
