    There are described the types of tea bush pruning and working bodies of the pruning devices in the article. Due to the biological condition and agro-technical requirements of the tea bushes, there are carried out five different types of pruning action in the tea plantations. Therefore it is necessary to discuss a different design pruning machines. The variability of the parameters of the cross-section of tea bushes on slope is analyzed, depending on the angle of slope inclination. Also the free line width , as well as the cross-section characteristic parameters of the tea bushes – , ℎ are established.
    Different types of surface formation of tea bush are characterized, including flat and semi-cylindrical forms. Their comparative analysis has been conducted. In order to increase their durability and simplifying of the construction of tea pruning and harvesting machines it is recommended to form a flat surface of tea bushes. Accordingly, It is recommended to reconstruct the existing semi-cylindrical shaped tea plantations with flat formation of the bushes surface.

    One of the most acute problems in the effective use of small-sized agricultural machinery, in particular, motor blocks, is the stabilization of their rectilinear motion on the slopes work. The purpose of this study is to increase the stabilizing moment of the motor block, by theoretically justifying its movement across the slope with a stabilizing device. The research uses modeling methods, theoretical mechanics and higher mathematics. As a result of the theoretical study, the conditions for the balance of the running wheels of the aggregate in the structure of the motor block and the agricultural implement when moving along the slope surface, as well as the traction of the wheels with the soil, are determined, taking into account the lateral force leading this unit down the slope. At the same time, as a stabilizing device, a micro-tiller is used, which makes it possible to pre-make a stabilizing groove for the wheels of the motor block. Further, using the developed power circuit, analytical expressions are compiled that allow us to numerically determine the structural and power parameters of a given aggregate, allowing it to stabilize its steady motion when working on a slope.
