The section of the strip tillage has a set of mutually located working bodies, sequentially performing the destruction, displacement and grinding of the soil aggregates with the corresponding processing quality and the state of transverse unevenness of the treated strip. The results of experimental studies of the dependence of the mutual arrangement of the parameters of the working bodies of the unit of the strip for strip tillage on the state of the transverse roughness of the treated strip and the quality of processing, which are provided by various design and technological parameters of the unit, are presented. Influencing factors of quality processing unit for band tillage is the depth of processing, the distance from the bit to the axis of the cutting disk, the width between the cutting discs, forming the width of the treated strip. It was established experimentally that the section of the strip tillage has a minimum transverse unevenness of the treated strip in the range from 8 to 15% when the distance between the cutting discs, that is, the width of the processed strip in the range from 22 to 38 cm, the distance from the bit to the axis of the cutting discs - 50 cm. With an increase in the depth of processing with a chisel, the transverse unevenness increases in direct proportion. Depending on the occurrence of the plow sole, the depth of chisel processing can be from 20 to 27 cm. With a mixed method of sowing row crops and caring for them, to ensure compliance with agro technical requirements, namely, transverse unevenness should not exceed 15%, the distance between the cutting discs is reasonable take at 30 cm. To ensure the normal operation of the section of the unit for band processing, it is necessary to further investigate the effects of changes in the relative position of the working bodies and technological parameters on the quality of processing.
