Abstract: 
The most important agricultural products in our country is wheat that plays an important and distinct role in preparing food for people.Like other products of agriculture, we see many losses in this product from producing to consuming. According to the results in harvesting irregular or old combines can affect the products by breaking grains or not separating the wheat from chaff. Doing this study, some parts of Varamin which have most wheat farming land have been chosen such as Javad Abad, Ghaleh Sin and Khaveh. The average of losses in Varimin has been estimated 7 percent for one hectare. Amount of losses was like this damage losses 4.2 percent, quantitative losses.1.6 percent, cylinder losses 0.6 and sieve losses 0.6 percent. It can be said that the main reasons for these losses were: age of combine, speed of machine, cuter bar height, planting method, lack of adaptation between reel speed and combine speed, the farmer’s lack of fumiliarity with the combine, incongruity speed of fans, weed pollution, unsuitable of grain wheat during harvesting and irregularity of sieve. Accordingly, there are some suggestions: Land leveling, determination of useful age of combines and the best time for replacing, farmer’s and operators training, arrangement of combine device parts and using suitable ways for planting and irrigation.
