| Summary: | This article presents a set of works that must be performed to maintain the ecology of the soil in the process of planning by planning machines. The smoothness of the movement of agricultural machines is ensured by reducing the unevenness of the surface of the cultivated field. In these studies, it was noted that the utilization rate of the planning machine depends on the speed of the unit, the length of the field section, the time spent on eliminating technical malfunctions, etc. Taking into account the mathematical dependencies, the coefficient of utilization of the shift time in function depends on movement speed, working width and specific working conditions and the value of the actual productivity of the planner per hour of shift time. The capacity of the planner was calculated according to the equation proposed by the researchers of this article, and does not differ much from the unit performance obtained during field tests, and the percentage of difference is 5 ... 6%. Therefore, the results of this work can be used for preliminary design and kitting-up of machine-tractor units for planning works of pre-sowing background of irrigation agriculture.
