The comparative evaluation of using of the basic models of domestic and foreign high-power wheel tractors, tillage machines composed of different technological applications. The problems of effi-ciency of using tractors in the composition of soil-cultivating units at cost, determining the cost of works carried out on the calculation of the direct operating costs. As objects of study were adopted high power domestic 4k4b wheel tractors K-744R3 (R3M) 4k4a ATM and foreign 4k4a 7360 JD-8530 and NH T-8050 with comparable parameter specifi-cations. These tractors are the basis of the updated tractor agrarian zone of East Siberian Federal Dis-trict. Calculation of technical and economic pa-rameters of tillage machines of different technologi-cal applications performed on the costs of individual transactions. In assessing the effectiveness of soil-cultivating units, a base for comparison is selected tractor K-744R3. The components of specific oper-ating costs analysis at different technologies of till-age showed that the highest costs of all types of soil treatment were obtained at the expense of de-preciation and maintenance of tractors. The annual costs of these items exceeded the performance of the tractor K-744R3 from 42 to 258 %. No signifi-cant reduction in cost (14-18 %) in all types of soil treatment was obtained at the expense of savings in operating materials. Analysis unit operating costs at different technologies of tillage showed that the price of the tractors of foreign production, in two or more times the price of the base model K-744R3 led to lower annual efficiency. Highest efficiency operation was achieved by using tractors K-744R3 on all operations of the main processing of the soil.
