Wheat is one of the important food staff in consumption pattern of each country. More than 50 % of human energy is supplied from bread in the developing country. Combine losses is less than 2-3% in developed countries, while in developing country is about 15-20% in different regions and circumstances of harvesting seasons and field conditions. In this research project that effect of combine type and wheat variety to grain losses and waists were investigated. Experimental design was split plot in a completely randomized block design with three replications. Wheat variety in two levels of Sardari and Omid as a main plot and combines type in two levels of John Deere (JD) 1055 and JD 955 as a sub plot. Field experiments were carried out in the farmers field with 5 ha area. The results showed that higher amount of losses were in the Omid variety and JD 955 with totally 5.97 % (306.3 kg ha-1) that 14.75 % of them attributed on the combine back, 41.6 % on Header, 5.4 % on Drum and 24.45 % on impurity and 13.8% on grain breakage. The lowest losses related to JD 1055 and Sardari variety with 3.12 % (160.05 kg ha-1) that 14.65 % of them attributed on the combine back, 35.7 % on Header, 4.5 % on Drum, 26.15 % on impurity and 19% on grain breakage.
