The purpose of this work was to study: interrelation of different levels of technical equipping concerning agricultural enterprises in which various groups of agricultural population are occupied; influences of technical equipping characteristics and some environment factors on the base technologies and their groups in agricultural works. Expenditure of energy by the operator at work in social production and in personal subsidiary plot are determined. Advantages of one-stage technologies of harvesting with green manuring or soil preprocessing are shown. The possibility of using one-stage technologies on the basis of new high-efficiency combine harvester RSM-181 with axial-rotor thresher is proved. Base technological complexes of machines concerning all five groups of rural commodity producers are constructed.

In view of the phased increase in field units' operating speeds it was necessary to explore the work of seed distributor on a specially made laboratory plant and in working conditions.

The results of study of an experimental plant based on tractor cistern spreader of liquid organic fertilizers with rod distributing system are given. Characteristics of a centrifugal pump and pump assembly are brought.

A way of estimation of complex agricultural unit's power balance components and of traction and power capacities of tractors is considered.

Results of use of mathematical autoregressive methods of identification of parameters of dynamic mathematical models are considered according to experiment of curvilinear movement of tractor-trailer system on the turn. Dynamic mathematical models of movement of tractor-trailer system are presented by the system of differential equations in the vector matrix form of statuses space variables. The rating of accuracy of models is executed.

An analysis of problems to be solved in the design, production and operation of modern four-stroke motor and tractor diesel's gas distribution mechanism.

The article analyzes main reasons of grain damage and loss in threshing and separating devices of various types. It gives some recommendations on the use of transverse threshing drums.

The mouldboard shifts the soil layer in vertical plane during the ploughing. The shear plane passes through the not undercut mass, which causes high wastes of energy. The offered construction of plough (patent №2335107) allows to reduce the energy consumption.

Using a new method for the soil cultivation quality assessment will allow to adjust, quickly and reliably, the instrument for soil loosening and weeds cutting according to the agrotechnical requirements. And for the operation quality control it is sufficient to count the uncut plants at one plot.

14-16 сентября 2010 года в г. Углич Минсельхоз РФ, Россельхозакадемия, ВИМ и Росинформагротех проводят ХI Международную научно-практическую конференцию «Автоматизация и информационное обеспечение производственных процессов в сельском хозяйстве».
