The paper presents the results of analysis of agricultural equipment condition and some indicators of agricultural equipment use in enterprises of agroindustrial complex. Directions of efficiency improvement of agricultural production are determined.

The article deals with the static stability for overturning of articulated front loader, depending on its location on the slope.

It is shown that owing to unevenness of wear of hoe blades located in different places of a frame, as well as to low relative service life and to inability to meet agrotechnical standards, the renewal of operational capability of the unit demands the complete replacement of hoe blades.

The article provides a brief overview of rotary threshing and separating devices of self-propelled combine harvesters. Geometric parameters of the rotors and trends of their development are given.

Convex functions of specific energy consumption of agricultural tractor are determined. Its optimum energy saturation corresponds to their minimum.

The article presents the results of studies on optimization of main energy parameters of tractor gas-turbine engines for machine-tractor units.

Innovative energy-saving A-hoe blade with stepped variable share has been developed. It allows to reduce energy consumption for operation of combined tillage machines.

Opportunities to reduce the emissions of toxic components with exhaust gases are evaluated, based on experimental tests of diesel engine operating on water-biofuel emulsion and diesel fuel.

The article presents the results of calculation researches of possibility for forcing of diesel engines produced by Vladimir motor-tractor plant to 22,1 (30); 25,7 (35) and 29,4 (40) kilowatt per liter (horsepower per liter). It substantiates the most appropriate indicators of diesel engine for the task.

The paper deals with the problem of lube oil supply to the parts of cylinder-piston unit of four-stroke internal combustion engine. The results pointing out an abnormal (non-uniform) character of motor oil distribution on cylinder wall sides taking the lateral force of piston are presented. The paper in general terms formulates the problem, the solving of which will allow to get a more adequate idea of cylinder oil supply and offer on this basis the technical solutions for improvement of this process.

Test bench for friction disks has been developed. It allows to investigate tribotechnical properties of material of full-scale specimens and to estimate the effect of friction material components on tribotechnical properties.

The process of high-temperature thermomechanical treatment with deformation by screw compression for hollow products has been developed. It is considered as a technical system that represents the set of functional relations between the elements such as: the modes of high-temperature thermomechanical treatment with deformation by screw compression, the geometry fidelity, the quality of working surfaces, the mechanical properties of the material, the operational life of part. Thus a connection is made between elementary x-qualities and performance properties.

The paper deals with the scheme of pump and battery supply of hydraulic mechanism of steering control of a wheeled vehicle with integrated unit of heat recuperation. The scheme allows to increase the pump life and the safety of vehicle control, including the cases of pump and engine failure and slow-speed maneuvering. In addition, the fuel consumption of steering pump drive is reduced, with the result that the fuel consumption of engine decreases.
