ABSTRACT
The article presents the results of the experimental studies on determining the optimal values of the roller of the
plowed land and selecting its type on the basis of this. In experimental studies, the provision of complete processing
of the field surface is ensured mainly by the selection of the type of roller and the planer for installation on the roller,
in order to obtain the required level of moisture for seed germination according to agrotechnical requirements. it is
noted that there are gear-plate, rod working parts. In order to verify these obtained results, we made plate, gear-
plate, and rod coils, which have a constant diameter, and conducted experimental studies using them. In experimental
studies, after using different rollers with a constant diameter, the influence of soil compaction, density and tensile
strength was studied. In order to reduce the influence of various variable factors on the obtained results, the
experiments were carried out on a specially prepared agro background, that is, it was first plowed and then leveled.
In order to test the theoretically based parameters of the roller selected for conducting experimental studies in field
conditions, the bases of the roller with a coverage width of 1.5 m and fixed-diameter bases with slats, toothed-slats,
and wire plates to be installed on them were developed. released and prepared.
Based on the results of experimental studies, the following can be noted: in order to ensure that the compaction
quality and density of the soil meet the agrotechnical requirements, and to ensure that the rolling resistance is
minimal, it is necessary to have a gear-plate roller.

INTRODUCTION
In our republic, comprehensive measures are being
taken to reduce labor and energy consumption, save
resources, grow agricultural crops based on advanced
technologies,
and
develop
high-performance
combined machines in preparation for planting grain
and repeated crops, and certain results are being
achieved. In the Strategy of Actions for further
development of the Republic of Uzbekistan in 2017-
2021, including "...modernization of agriculture,
consistent development of production of agricultural
products, further strengthening of food security of our
country, high productivity "use of agricultural
machinery"
tasks
are
defined
[2].
In
the
implementation of these tasks, including all
technological processes for preparing the soil for
planting (full compaction of the driving layer, leveling
and grinding of the surface of the field) in one pass
through the field, i.e. before planting One of the
important issues is the development of a combined
machine that provides comprehensive processing of
teeth [1; 2; 3].
factors in the selection and justification of parameters
of soil tillage machines, as well as in the assessment of
their performance.
METHODS
Based on the analysis of the literature carried out for
the purpose of choosing the optimal type of roller,
comparative tests of planar, toothed planar and rod
rollers were conducted.
In order to carry out comparative tests, flat, toothed
flat and rod rollers with the same diameter of 40 cm
and a coverage width of 1.5 m and a special frame
(laboratory-field device) on which they are installed
were developed, and their experiment was carried out.
Copies were prepared [ 5; 6; 7; 8].
The laboratory-field device was designed to allow for
the installation of different types of coils and the ability
to vary the vertical pressure applied to them over a
wide range.
Comparison trials were conducted in a post-harvest
wheat field that was irrigated and plowed and surfaced
with a machine equipped with disc rollers and a leveler.
The tests were conducted in the third and fourth gears
of the MTZ-80 tractor.
Soil moisture and hardness in 0-10 and 10-20 cm layers
were determined according to the mentioned
methods before conducting comparative tests of
rolling mills. Their results are in the table given.

evaluation criteria, the compaction quality of the soil in
the 0-10 cm layer, its density, and the tensile strength
of the rollers were taken.
Tenzofingers were calibrated before and after the
experiments. In this, they were given a load in the
range of 0-5 kN with an interval of 1 kN. The results of
the tests are presented in Table 2.
RESULTS
Based on them, the following can be noted:
- in terms of the quality of soil compaction, the toothed
plate roller had higher

indicators compared to the plate and rod rollers. A
roller with a rod and a plate grinds the pieces a little
less well than it. As a result, the amount of fractions
smaller than 25 mm is 8.1-8.9 and 4.2-5.4 percent less,
respectively, when processing with wire and plate
rollers compared to processing with toothed plate
rollers. The amount of fractions larger than 50 mm was
6.2-7.2 and 3.4-3.6% higher;
- the density of the soil was almost the same in all three
coils;
- to draw a roller with a toothed plate according to the
results of tensometry
the largest, and the coil with the wire provided the
least resistance. This can be explained by the
difference in the depth of their immersion in the soil.
It is clear that the roller with a toothed plate is buried
deeper in the soil, and the roller with a rod is shallower
[6; 7;].
The increase in the speed of the unit from 6.2 km/h to
8.3 km/h led to the improvement of the quality of soil
compaction, decrease in density and increase in the
traction resistance of the rollers.
From the observations, it became clear that after the
passing of the plate and toothed plate rollers, a soft
layer of 3-4 cm thickness was formed on the surface of
the field, which ensures the preservation of moisture
in the soil. the layer was not sufficiently formed.

The plow is equipped only with disc rollers and a
leveler, that is, when working with a machine without
rollers, the soil does not meet the requirements for the
planting background in terms of the quality of soil
compaction, density and leveling of the surface part.
According to the results of the comparative tests, a
toothed plate roller is recommended for installation on
plowed land, and its parameters will be investigated in
further studies.
