During the operation of the tractor unit in field operations, not all the power developed by the tractor engine is effectively spent on useful work.
To use the tractor power effectively, reduce or eliminate its useless losses, the article considers the tractor power balance, showing the distribution of effective power among the individual components for traction and driving their working details. According to theoretical studies, it was found that the traction resistance of a wide-seeder with clutch openers consists of two components; this is the resistance of the hopper to movement and the resistance of the filling part
It was found that traction resistance will decrease as the hopper empties. The pulling resistance of the embedment is made up of several components, with the maximum permissible working speed of the unit, the maximum embedment depth and the highest seed sowing rate, the required power to perform the sowing process is obtained within 120 kW (163, 155 h.p), excluding the tractor power for raising or lowering the side sections of the sealing part. The total power consumption is distributed as follows: 90,8% to overcome the traction resistance of the wide seed drill, 9,1% for the fan hydraulic drive, and the remaining 0,1% for the electric meter.
To reduce the amount of required power for the sowing process, it is necessary to work in the direction of reducing the seeder mass and improving the design parameters of working coulters.

The article presents the chisel plow of the new generation developed on the basis of the systematic approach and adaptability of technological impacts from soil-climatic and agro landscape conditions. The principle of the use of the alternating movement of working elements for the destruction of the layer in the so-called lines of the least connections was built into the basis of the chisel plow construction. The chisel plow is multipurpose: it performs the present technological process of soil processing of fields on different depth and spaces between rows of perennial plants on the depth which is differentially changed distancing from the bole due to the architectonics of the root system disposition. Working elements of the chisel plow contain the fastened clutches on hinges, the angle of the mounting is determined by the action of soil resistance forces but the destruction of the layer is executed by differently directed deformations. Researches showed that the chisel plow qualitatively fulfills the present technological process and corresponds to agro-technical demands. The amount of agronomically valuable aggregates increases in the arable layer under the processing of soil by the chisel plow. The chisel plow is fairly aggregated with the Т-150K according to energetic indexes. The decrease in traction resistance (by 12.27%) and specific energy consumption (1.14%) when using the working elements with self-centered clutches have been observed. There was set the reasonability of the application of the type without clutches at the deeper tillage, and it is necessary to use the chisel plow with self-centered clutches under the soil treatment on small and medium depth. To treat soil in arid conditions there was developed the construction of the combined chisel plow presenting the combination of the chisel plow with a roller. The comparative analysis of technological process indexes testifies increasing the quality under function of the chisel plow with a roller and unimportant increase of power inputs in normal ranges. According to the acceptance tests on the SouthCaucasian MIS chisel plow is recommended to the application in agricultural production.
