To care for crops without damaging plant sprouts, a safe distance must be maintained from the wheels of the tractor and the working parts of the agricultural machine to the root system of the plant rows, which is determined by the size of the protective zone. Despite this, in some cases, during inter-row cultivation or care of crops, damage occurs to individual plant sprouts that are significantly deviated from the axis of symmetry of the row. This is due to the type of location of the seeds during sowing relative to the axis of symmetry of the seed row, the profile of the field and the content of the soil fraction of the surface layer of soil located above the sown seeds, gaps in the steering drive connections and the qualifications of the driver. Among them, the first two factors are probabilistic in nature and significantly affect the deviation of seedlings from the straightness of the rows and the setting of the size of the protective zone. Theoretical and experimental studies have shown that the deviation of sprouts under the influence of these factors from the straightness of the rows of plants is on average ±2.58 cm, which should be taken into account when determining the size of the protective zone.

“…The Design and Technological Center of Agricultural Machinery LLC (DTCAM) is developing a mechanism for changing the clearance of the rear axle (Figure 2), which makes it possible to change the agrotechnical clearance of the tractor from 600 to 870 mm [18,19,22].…”

In accordance with the agricultural row-crops cultivation practices adopted in the Central Asian region, machine-tractor units carry out a large number of passes through the field during the growing season. Consequently, individual sections of the fields are repeatedly affected by the running systems of these machines, which negatively affects soil fertility. The universal row-crop tractors used in cotton production have two types of wheel arrangements: 3W2 and 4W2. Consequently, these arrangements have different natures and magnitude of impact on the soil. Despite a number of advantages of 4-wheeled tractors due to insufficient agrotechnical clearance under the front and rear axles beam, they are not used for inter-row cotton cultivation. Mechanisms including a stepless change in ground clearance, both for the front and rear axles of a 4-wheeled tractor, eliminate these disadvantages and thereby expand the possibilities of their use. The use of a 4-wheeled tractor in field and transport operations has shown that the most loaded parts in the developed mechanism for changing the clearance of the rear axle are rolling supports of the cage on the casing of the rear axle of the tractor.
