“…Energy saturation of these tractors has a tendency to increase constantly [3]. At the same time, a share of soil-processing aggregates with traction and drive working units is increasing in agricultural machine-building as well [4]. The rational assembling of such aggregates on the basis of traction-energy concept tractors foresees the application of the effective engine capacity not only on the traction, but also on the active drive of working units or technological equipment.…”

At present the appearance of novel energy-saturated tractors of traction-energy concept requires not only new principles of their aggregating but also the method of assembling aggregates on their basis. Aim. To increase the effi ciency of assembling soil-processing aggregates with traction and drive working units based on energy- saturated tractors of traction-energy concept. Methods. The study involved the use of the methods of tractor theory, use of machines, fi eld experimental investigations, statistical methods of processing study results, as well as methods of composing programs and numerical computations on PC. Results. The method of assem- bling soil-processing aggregates with traction and drive working units was suggested on the basis of technical information, available for a wide audience of specialists. Conclusions. The problem of assembling soil-pro- cessing aggregates with traction and drive working units on the basis of energy-saturated tractors of tractor- energy concept should be solved with the consideration of the suggested condition of useful power via traction, determined by the friction properties of a tractor, and the power which the tractor can actually transmit via a power take-off shaft or a hydrosystem.

The performance potential of the existing grain cleaning assemblies meant for nominal and stable gross grain flow in view of the agrotechnical harvest time is not realized to the full extent. It is preconditioned by the instability of the technical and technological parameters of the harvesting processes. It results in a disproportion between the harvesting and the grain cleaning process, which is manifested in accumulation of bulks of grains within open areas in uncontrolled conditions or preconditions over-estimation of the rated performance of the grain cleaning assemblies. Their required performance can be decreased and the alignment of functioning of the process system can be increased by introduction of compensating and back-up components in view of the seasonal and daily performance indicators of the combine harvesters.

“…Scientific methods were used in the research process: modeling -to build an investment model for the development of the agricultural sector of the economy; economic and statistical -to assess the dynamics of capital investment; analysis and synthesis -to find out the reasons that cause changes in capital investment. A distinctive feature of the research [4][5][6][7][8][9][10] is that one of the priority tasks of improving the efficiency of mechanized processes in agriculture is considered the task of increasing the daily and seasonal output of the machine and tractor fleet.…”

This work is devoted to development of economic and mathematical models for selection of the optimum investment solution. Moreover, it states the basis for development of model examples and correction of the model considering the results obtained in the examples. In the work the problem is set for selection of the investment sources and objects, which is limited to the linear programming problem. The controlled variable and basic limitations simulating real credit and monetary relations are distinguished in the provided model. The discounted profit obtained from implementation of the optimum investment portfolio is considered as a target function. The economic and mathematical model presented in the article allows finding the optimum investment solution within the limits of the credit and monetary relations taking place both at the micro- and macroeconomic level.
