The main negative effects of pure rape oil application as fuel in stock engines are pointed out. Construction and operation principle of fuel heater, which permits to use rape oil and its mixing with diesel fuel are described. Calculation of fuel heater construction is given.

The hypothesis is put forward that for working organs of rotary cultivators the kinematic construction perfection by means of optimization of an angle of installation of a knife on the tiller rotor in a combination with continuously variable regulating of the kinematic parameter can be considered as an effective way of their service life extension. The regulating have to proceed from predicted deterioration of a back part of a knife in running-in time interval.

Methods and equipment for grubbing on glades and for reconstruction of shelter belts have been analyzed aiming to decrease of power and materials consumption of procedure and conditioning for full mechanization of the works and increase in productivity. The analysis results are presented.

Standard imported and domestic kale drills do not fully comply with agro technical requirements by seed distribution quality. Solutions permitting to increase seed distribution quality by means of uniformity of seed distribution on the growing space and prevention of seed damage are examined.

The mathematical methods, model and algorithm of optimal designing of skidding trails from condition of minimal damage on depth of a track from tractor passes are considered. Alternatives of construction design for one of felling area are offered.

The basic dependences of reinforcement processes are examined. The order of quality assessment of the processed surface and results of metallographic examinations of the reinforced samples are given.

Results of experimental researches concerning tin foil application as fatigue sensors for detection of small amplitudes of cyclic voltage of parts are presented. Control was carried out on appearance of dislocations traces on a sensor surface, and also by means of whirling currents. High sensitivity of tin foil fatigue sensing is shown.

Additional methodical rules of identification, modelling and analysis of pollution of operating fluids and oils are substantiated.

Wheeled vehicle transverse stability of turns and at immobile block impact was analyzed. Main factors influencing on critical roll-over speed were examined. Ways of transverse stability of wheeled vehicle improving are outlined.

Tracks of different types have been tested on the one machine (agricultural tractor). Tractive properties, noise and vibration level, rate of soil compacting action were assessed. The test results are given.

During the calculation of permissible regimes by way of adjusting tolerance for setting operation level on current value of the controlled parameter it is necessary to take into consideration probabilistic nature of load and other factors which act continuously and systematically change operational indexes of machine and tractor aggregate.

It is proposed to use diesel-generator as autonomous power-supply sources (APS) at the expense of complete utilization of exhaust gases (EG) heat and heat extraction from heat engine cooling jacket. Functional diagram of APS with complete heat utilization, as well as results of comparable tests of APS operation in common and impulse modes are given.

Problems of combine machinery market behavior is considered, including issues of actual fleet state, domestic production, import.

The creation urgency of mobile means of small-scale mechanization relates to implementation of an additional source of foodstuff obtaining. One of the main tasks is providing of small-size technics with power drive means.

The improved method of thermal balance calculation in production areas in agrarian and industrial complex for microclimate regulating is considered.

The construction of vibration and pneumatic planting unit intended for oriented bulbaceous crops planting is suggested. Theoretical substantiation of the disposition of bulbs inlet to pneumatic drum, as well as results of its experimental verification are given.

A priory ranking method for quantitative estimation of the contribution of specified subsystems in achievement of the purpose of system (a tree of objectives and a tree of systems) is considered. Presence of essential similarity of expert opinions, the significance of concordance factor and definiteness of expert opinion coincidence is determined. The structural contribution of each of subsystems to achievement of the general objective is estimated.

Results of the theoretical investigation dealing with the choose of optimal structure and parameters of vibration protection system for transport unit of a motor cultivator are given. Engineering design of adjustable seat suspension with fitted parameters is suggested.

Theoretical preconditions for choose of optimal loading modes and operation indexes of wheeled tractors as part of ploughing and cultivating aggregates are given. The optimal levels of energy parameters and technical-and-economic indexes ensuring their effective using were determined.

Based on the conducted parametric tests of the input and mixing equipment mathematical models of the working process are obtained, allowing to determine supply and pressure parameters when the material is loaded in the loading chamber and when the material is absent.
