Multiple passes of combined units across the field, associated with the need to perform several operations, inevitably lead to excessive compaction and spraying of the soil. Repeated treatment is especially harmful in the conditions of the Republic of Buryatia, where there is insufficient moisture and light sandy loam soils. In this regard, combined machines and units are becoming widespread, performing several operations in one pass: for example, plowing, cultivating, harrowing and rolling, pre-sowing tillage and sowing, applying fertilizers, herbicides or other chemicals. The use of combined machines reduces the harmful effects of wheeled propulsion on the soil, reduces the time required for operations, improves the quality of work and labor productivity, and reduces production costs. Combined machines and units must contain a set of working parts to simultaneously perform only those operations that can be combined in time without violating agricultural technology, timing and quality of execution.
