On the slipping of friction clutches during gear shifting without interruption of power flow in gearboxes of cars and tractors
Abstract
The article considers the slipping process of friction clutches in gearboxes of cars and tractors during gear shifting without interruption of power flow. It is proved that the gear shifting process in gearbox without power flow interruption occurs when clutch friction discs of engaged gear are slipping and discs of disengaging gear are closed. At this, the value of torque transmitted by disengaging friction clutch in gearbox depends on a value of frictional moment of engaging friction clutch. The results of this article also apply to composite gearboxes such as DSG (Direct Shift Gearbox).

Pneumatic delivery and deposition of drops of working fluid on plants to protect them from pests, diseases and weeds
Abstract
The article presents the results of researches on the pneumatic delivery of working fluid drops to plants with the maximum deposition and fixing of appropriately sized drops on stalks and leaves with the use of additional air stream. To solve the problem of sweeping out and deposition of fine aerosol on plants, it is proposed to use in boom sprayer a pneumatic device with slotted nozzles.

Soil cultivation work spent by unit
Abstract
Obtained equations allow to determine the influence of soil cultivation depth, characteristics of working organs and used structural materials on the productivity of unit. Optimal values of grasp width and unit motion speed providing maximum performance are defined. Expediency of using units with low power tractors and automatic control, or units in which tractors are not used as means of traction is proved.
