“…An adjustable tension spring acts on the parallelogram linkage system to press the row unit down until the depth set at the gauge wheel is achieved. This maintains the set depth while providing adequate stability to the row unit [ 26 ]. The spring tension can be varied as per soil conditions and type by shifting its movable end.…”

The growing demand for agricultural output and limited resources encourage precision applications to generate higher-order output by utilizing minimal inputs of seed, fertilizer, land, and water. An electronically operated planter was developed, considering problems like ground-wheel skidding, field vibration, and the lack of ease in field adjustments of ground-wheel-driven seed-metering plates. The seed-metering plate of each unit of the developed planter is individually driven by a brushless direct current (BLDC) motor, and a BLDC motor-based aspirator is attached for pneumatic suction of seeds. The revolutions per minute (RPM) of the seed-metering plate are controlled by a microcontroller as per the received data relating to RPM from the ground wheel and the current RPM of the seed-metering plate. A feedback loop with proportional integral derivative (PID) control is responsible for reducing the error. Additionally, each row unit is attached to a parallelogram-based depth control system that can provide depth between 0 and 100 mm. The suction pressure in each unit is regulated as per seed type using the RPM control knob of an individual BLDC motor-based aspirator. The row-to-row spacing can be changed from 350 mm to any desired spacing. The cotton variety selected for the study was RCH 659, and the crucial parameters like orifice size, vacuum pressure, and forward speed were optimized in the laboratory with the adoption of a central composite rotatable design. An orifice diameter of 2.947 mm with vacuum pressure of 3.961 kPa and forward speed of 4.261 km/h was found optimal. A quality feed index of 93% with a precision index of 8.01% was observed from laboratory tests under optimized conditions. Quality feed index and precision index values of 88.8 and 12.75%, respectively, were obtained from field tests under optimized conditions.

“…This dependence is clearly expressed in those areas where the cultivation of agricultural crops requires multiple passes of mobile agricultural machinery through the field [4]. For example, in accordance with the cotton cultivation technology adopted in the Central Asian region, aisles are cultivated (3-5 times), and furrows are cut for irrigation, spraying against pests and diseases [5,21], to prepare for harvesting a ripe crop, defoliation and sometimes desiccation of cotton are carried out, followed by machine harvesting of the raw cotton [6].…”

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.

As the object of the research, the cotton stalk and its physical and mechanical properties, the elastic of the combined aggregate and the spherical disk were accepted. Like many other European countries, our country has also developed minimal, resource-saving and zero technologies for the cultivation of agricultural products, and their technical solutions are being supported and implemented by farmers and clusters. In particular, in the preparation of cotton fields for sowing for the next year in one pass of machinery in cotton growing, the research was conducted on the development of a minimum technology and a combined unit that implements it. In the implementation of this technology, the cotton stalks are tilted to the side furrow in the direction of movement of the aggregate, and the root is laid on the bottom of the furrow with the soil. The bottom layer of the existing pile is then divided into two parts, each of which is rolled over the cotton stalks on the side edges on both sides, where a new pile is formed. Once the aggregate has passed, the existing ridges are replaced by ridges with cotton stalks buried under them, and ridges are formed in place of the existing ridges. In the study, the angle of the axis of symmetry was determined by the angle of the stalks, and in the laboratory, the amount of force required to bend the stalks was determined using a specially prepared stand. In the study, the width of the flexible cover is 45 cm, the mounting angle of the straight part of the flexible relative to the direction of movement is 35-450, the radius of curvature should be 100 mm, the mounting height relative to the ridge should be 15 cm, and the shape was determined. Bending of cotton stalks standing on the ridge in the direction of aggregate movement to the side ridge, digging them with root soil, longitudinal laying at the bottom of this ridge can be done using a spherical disk.
