Abstract.
The aim of this paper is to create a combined machine for 
planning the soil for sowing cotton on the edges. A total for the execution 
of the innovation of planning the soil for sowing cotton on the edges was 
developed, which comprises of a dump deep-dredger with a slanted rack 
and a comb-maker. The essential standards and strategies of classical 
mechanics, numerical examination and measurements were utilized in this 
paper. The plan conspire of the combined unit is advocated. The 
following results were obtained from the outcomes of multivariate tests 
set up: the width of the ripper within the extend of 10.5-11.03 cm, the 
disintegrating point of 27°, the point of establishment of the plowshare 
edge to the heading of movement of 31°. The arrangement of edges of the 
desired degree with negligible vitality utilization is given with a width 
and length of the deep-dredger bit, separately, of 5 and 20 cm, edge hold 
width of 21 cm, the length of its wing within the run of 47-49 cm, and a 
least longitudinal.

Introduction 
Methods of mechanical tillage with a rational technology of cultivation of 
agricultural crops, strive to create optimal conditions for the growth and 
development of plants, that is give the soil a condition in which at the depth of 
processing it becomes clear of weeds, has a certain density and porosity, providing 
better seed germination, better conditions for absorbing moisture and preserving it

from evaporating, which ultimately allows getting high programmed yields. 
However, in some cases, the required soil condition during mechanical processing 
performed by existing machines and tools can be achieved only with multiple 
passes of the units. The currently accepted technology of cultivation of agricultural 
crops provides for up to 10-12 operations [1-5]. Particularly a huge number of 
operations are required when developing cotton. Rehashed passes of totals through 
the field adversely influence the compaction of the soil and cause the devastation 
of protuberances of the foremost ideal sizes, which leads to a diminish in trim 
yields. In this respect, an unused innovation of development of agrarian crops has 
ended up widespread in all nations of the world 
–
the combination of operations, 
which permits, at the side an increment in edit surrender, to extend labor efficiency 
by 1.5-3 times and diminish costs per unit of yield [6-12]. F. M. Mamatov [1-23],
