A
BSTRACT
This article examines the care and maintenance of row crops, focusing on the efficiency of active and
inactive working bodies of cultivators. The study provides a detailed analysis of their impact on soil
aeration, weed control, and crop productivity. Particular attention is given to the design and functionality
of a newly developed tool for loosening soil in the row-spacing of cotton. The innovative mechanism is
designed to improve soil permeability, enhance root development, and optimize moisture retention. The
article also presents preliminary research findings, highlighting the tool's effectiveness compared to
conventional cultivation methods. The results indicate that the new design reduces soil compaction while
maintaining the necessary structural integrity for plant growth. These insights contribute to the
advancement of precision agriculture and sustainable cotton cultivation practices.

Row cultivators cultivate the soil between rows of
cotton crops to destroy weeds and loosen the soil
both between rows and in protective zones,
preserving the loose and fine-grained topsoil.
Four to six inter-row cultivations are carried out
for plants during the growing season. After the
first cultivation, a delay leads to rapid
development of weeds, delayed flowering and
maturation of plants and, ultimately, to a decrease
in yield.
M
ETHODS
The cultivator's working parts are placed at the
required distance from the row so as not to
damage the plants. Thus, after the cultivator has
passed, a free strip remains on both sides of the
row, which serves as a protective zone. The width
of the protective zone depends on the following
factors: the type of crop, variety, degree of plant
development, depth of soil loosening, quality of
irrigation (straightness of rows), the magnitude
of horizontal deviations of the cultivator's
working parts located perpendicular to the
direction of movement, and the types of tools
used for inter-row cultivation. The wider the
inter-row strip processed by the cultivator's
working parts, the less area remains for manual
processing.
Rotary cultivator working bodies reduce the
protective zone compared to traditional passive
working bodies [1,2,3,4,5]. When processing with
standard loosening working bodies, they are
installed at a depth of 14-15 cm, and when
weeding at a depth of 6-10 cm. The protective
zone is 15-20 cm in both cases.
In recent years, new machines for inter-row soil
cultivation have been developed in our country
and abroad. These include implements with
rotary working bodies that rotate due to
interaction with the soil or from the tractor power
take-off shaft. The agronomic and technological
advantages of such implements exceed
traditional ones; in particular, they are
distinguished by the high quality of soil
cultivation and rational use of tractor engine
power [6,7]. However, due to the low productivity
and complexity of the design of rotary working
bodies rotating from the PTO, tractors are rarely
used and only in difficult areas that are difficult to
cultivate with conventional equipment. The
possibilities of using cultivators with wireless
rotary working bodies should be expanded.
The Swiss companies "НG Haruwy" and "Muller"
produce various types of tools for inter-row
cultivation with a horizontal axis of rotation [8-
10]. Soviet specialists used such tools at their
machine testing stations to evaluate the quality of
work.

Fig. 1. New working element of a row-crop cultivator.
The new tool pertains to agricultural machines, in
particular cultivators, which are used for
loosening the soil crust on cotton crops. The aim
is to improve the quality of soil cultivation when
loosening the crust on cotton crops. This device
for cultivating row crops comprises rollers 4 and
5, which are successively mounted on frame 1
using rotations 2 and 3. Two hubs 6 and 7 of the
front roller 4 are separated by a replaceable
bushing and are mounted on a horizontal axis. For
stages 6 and 7, disc knives 10 and transverse
loosening elements 12 are used. Hubs 13 and 14
on the rear roller 5 have the shape of truncated
cones, which face each other with their smaller
bases. Conical loosening elements 17 are located
on the conical surface of hubs 13 and 14. To limit
the depth of loosening, axially located flanges 11
and 18 are located on hubs 6, 7, 13, and 14. Roller
four breaks the longitudinal strip of the earth's
crust, and roller five breaks it into smaller pieces.
This tool consists of fork-shaped leads 2, and 3 of
the front and rear rollers 4, and 5, which are
attached to frame 1.
Two 6, 7 are pivotally mounted on a transverse
horizontal axis 8, pivotally mounted on a leash 2.
Hubs 6 and 7 are located at some distance from
each other and have the shape of a cylinder
relative to the longitudinal axis of the implement.
On axis 8 between hubs 6 and 7 an adjacent
bushing 9 is installed. Each cylinder has a radial
disk knife 10 with a cutting edge protruding
beyond the surface of the cylinder, fixed on a
more distant axis of the longitudinal axis of the
implement. To limit the depth of the loosening
elements 12 of the roller 4 on the side surface of
the disk of the knife 10 or directly of the cylinder
(depending on the location of the knife
attachment) there is an axially located annular
projection 11 (flange). On the cylindrical surface
of the hubs of these elements, there are elongated

radial projections located transversely to the
direction of their rotation.
Two hinges 13,14 are pivotally mounted on a
transverse horizontal axis 15, which is pivotally
mounted in a driver 3. Hubs 13 and 14 have a
truncated cone. They are connected to each other
by smaller bases of the cones and are separated
from each other by a replaceable bushing 16.
Loosening elements 17, having radial projections
of a conical shape, are located on the conical
surface of hubs 13 and 14. In order to limit the
deepening of elements 17, an annular projection
or flange 18 is located axially on the large bases of
the cones.

ONCLUSION
The results of testing the new tool demonstrate
its efficiency in breaking and loosening the soil
crust. The front roller effectively cuts a
longitudinal strip of the hardened soil layer,
initiating the breaking process, while the rear
roller further fragments and loosens the crust
into smaller pieces. This dual-action mechanism
ensures improved soil aeration and water
infiltration. Moreover, the tool has shown
potential for application in rough and compacted
soils, expanding its usability beyond cotton row-
spacing to other crops requiring similar
cultivation techniques. These findings contribute
to the development of more efficient and
sustainable soil management practices in modern
agriculture.
