The results of tests of devices for sunflower harvesting differing in design, the number of rows to be removed, the presence of the chopper stems in real economic conditions and machine testing stations.

The sowing technology for the germinated watermelon seeds is developed. It includes seed presowing treatment by electroactivated water and germinated seeds sowing by new construction of seed distributor, using single-grain and hole sowing method.

Analysis of the level of mechanization in the cultivation of soil in the planting of seedlings and seedlings of forest and garden crops necessary for the destruction of weeds, soil content in the loose state, making the root layer of the soil of nutrients, etc., revealed that inter-row processing has a 100% level. However, it remains untreated rows of plants that includes the protection zone, which requires to perform operations on rows in significant expenditures of manual labor, constituting 40...50 people/hour in 1 hectare. The optimum variant of technology of planting care of seedlings seedlings of forest and horticultural crops would be the conversion of cultivators KRN working body, allows to conduct processing of soil in the rows of plants. At the same time, operations of soil treatment are carried out both in row and row spacing. All known methods of tillage in a row require the use of special working bodies that provide loosening of the soil in a row and cutting weeds. Such working bodies should provide the necessary protective zone around the plants. The developed design of the working body is installed on the row cultivator KRN over the processed row, which provides one-time processing of row spacing and rows. The article presents the results of theoretical studies of a special working body.
