For the increasing of the efficiency of mechanization of the mobile technological processes in plant growing production it is necessary to form the profile of tractors and machine stock which is maximally adapted to the requirements which are specified by the natural and production usage conditions. The man factors which characterized these conditions are the length of working plots bout and the yielding capacity of cultivated crops. Method for the revelation of the regularities of the statistical distribution of the observed values is presented. Statistical evaluation of the distribution agricultural institutions of the Republic of Belarus according to yielding capacity indices (in 2006) of the main agricultural crops (cereals, potato, vegetables, sugar beet) and according to the bout length is presented. Yielding capacity gradation for the evaluation of exploitation conditions of combine harvesters is analysed. Gradation density of agricultural crops yields in accordance with the conditions of agricultural harvesting machinery exploitation is calculated. Research results show that influence of crop yielding capacity on the performance value has an impact on the work of harvesting machines and can be calculated using the standards of fuel expenses and machinery output
