One of the ways to increase productivity of plowing unit is to meet the conditions of stability of the implement’s stroke at the least frictional forces of plough from pressure on the bottom and walls of the furrow. The direction of the traction line in the horizontal plane has a great influence on the resistance of the plough and the stability of its movement. The purpose of the research is to substantiate the optimal modes of operation of a tillage unit in the performance of technological operations. The laws of physical-mechanical and technological properties of soil were used in the analysis of working processes of agricultural machinery operation. Calculations were made to determine the tractor gauge for aggregating ploughs with different numbers of bodies and their working widths: the less hulls plough - the greater the pressure force, with 4 hulls the efficiency increases smoothly to 60% - 80%; with multibody ploughs (12 hull) efficiency can to 100%. The plow manufacturers should place the pull point at a distance from the center line towards the furrow by an amount equal to 1/3 of the length from the center of resistance to the pull point. Provided that plowing in the furrow: the track width of tractors when working with 1-4 body plows should be 0.65 … 0.95 m, when aggregating with plows from 5 to 14 bodies - 1.10 … 2, 69 m.

The research was carried out in order to develop an energy mathematical model of a plant protection unit with a trailed sprayer, which makes it possible to optimize the parameters and operating modes, taking into account their influence on the size and loss of crop yield. For comparison with the tendencies of changes in the parameters of sprayers established in practice, computational experiments were performed using the developed mathematical model. The object of study is an analogue of MTZ-82 tractor, the main parameters of which (mass, engine power, kinematic length, etc.) can be changed, an analogue of a trailed sprayer with variable parameters (width, operating speed, tank volume, drawbar length, location of the center of mass, profile width and support wheel diameter, etc.). The optimization criterion was composite and included the sum of direct and indirect energy costs during the operation of the unit, taking into account the energy of the crop lost due to deviations from the optimal parameters and operating modes of the sprayer. Incorrect choice of unit parameters leads to yield losses, resulting from its decrease due to a violation of the deadline for performing a technological operation to protect crops from weeds, trampling down part of the crops by the unit's movers during processing, especially if there is no possibility of turning outside the field, due to soil compaction in the zone of growth and development of plant root systems. Computational experiments carried out using the developed energy mathematical model showed that an increase in sprayer coverage from 16 to 32 m at an aggregate speed of 12 km/h leads to a decrease in total energy costs from 3250 MJ/ha to 1692 MJ/ha, an increase in the unit speed from 7 to 12 km/h, with a working width of 32 m reduces the total energy costs from 1971 to 1692 MJ/ha. Reducing the width of the sprayer wheel tire profile from 0.6 to 0.2 m is accompanied by a decrease in total energy costs from 2793 MJ/ha to 1692 MJ/ha.
