Adaptive technical equipping of rural commodity producers
Abstract
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.

Discrepancy of kinematics of turning steering wheels and efficiency of running gears for wheeled machines
Abstract
The method of quantitative estimation of influence of steering wheels turning kinematics mismatch on the efficiency of running gears for wheeled machines is developed. Results of application of this method on the off-road vehicle with 8х8 wheel formula and two front steered axles are presented.

Identification of parameters of dynamic movement model for tractor-trailer system on the turn
Abstract
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.

Comparative assessment of some variants of stepless turning mechanism for caterpillar farm tractor
Abstract
The article describes three variants of kinematic diagrams of stepless turning mechanisms of caterpillar tractor, based on two planetary gears with outer and inner engaging gears with different application of their elements to serve input, output and control links and driving of control link from hydrostatic motor. The results of their comparision and assessment are brought.

Reducing grain damage during the separation with ascending air stream
Abstract
Authors reveal the main causes of excessive grain damage during its processing in grain cleaning machines. They suggest a design of pneumatic separator based on the using of air stream which separates grain and other bulk materials, it allows to reduce the seed damage by decreasing the critical speed of fracture initiation.

An analysis of energy consumption for the displacement of soil in vertical plane with a mouldboard during the ploughing
Abstract
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.

Mathematical modeling of geometric dimensions of thermal chambers for infrared installations
Abstract
The technique of estimation and calculation of geometrical sizes of infrared equipment thermal chambers is developed. The dimensionless coefficient of infrared equipment using, and also the dimensionless index of thermal chamber are suggested as criterions of optimality. On the basis of the described technique an experimental thermal chamber for infrared installation is developed. Analytical and experimental researches of its basic parameters are carried out.
