The article found that the targeted management of parameters affecting the production arm can influence the value of the break-even point and increase the potential for the formation of the gross profits of small repair shops
While mechanical harvesting of potatoes, about
20-40% of the tubers get damages. Dynamic
loads, injuries of the tubers, causing internal
damage – which is browning of the flesh of the tuber, which occurs in the process of its storage.
At the same time, ways to express control of
damage to potato tubers will allow both
reducing damage during harvest, and promptly
sending damaged potatoes for recycling before
the results of mechanical stress for the tubers
during harvesting. The definition of internal
damage to the potatoes is possible because of
the analysis of the different elasticity of the
tissues of damaged and undamaged tubers. The
value of overpressure of the device is chosen
such way that during deformation of tubers
there mainly has been compression of the
damaged tissues of the tuber, with the least
turgor. The degree of damage of samples of
tubers is determined by the ratio of the volume
of damaged tissues of tubers to the total volume
of the sample. We have given the mechanical
properties of tissues of tubers, fruits and root
vegetables, their structure, dimensional
characteristics, it can be assumed that the use of
this method of determining internal damage
possible for apples, carrots, beets and harvest of
other crops. Use of damage control will enable
timely identification of hidden damage and
make it possible to eliminate their causes,
which lead to increase loss products
In the general complex of mechanized works when
growing potatoes, potato harvesting is one of the main
operations. The efficiency of potatoes growing at the
farm largely depends on harvest quality and crop
retrieval. When harvesting potatoes with potato
harvesters their productivity largely depends on the
state of potato haulm. In a case of evolved and laid
haulm the harvesting machines productivity falls
sharply due to working organs clogging and in some
cases their work is not possible at all. Therefore, to
facilitate the work of potato harvesters it is necessary
to remove potato haulm before harvesting. But the
process of haulm removing is very laborious, including
several operations, such as mowing, raking and
transportation, each of which is performed by a
separate machine. The appearance of domestically
made rotary-type machines like KIR-1.5, UBD-3 and
BD-4 at the end of 1950-1960 made it possible to
mechanize the harvesting process of potato haulm. But
it was noticed in the operation that rotor machines
have a number of drawbacks caused by imperfections
in the rotor design, its kinematic regimes, lack of
balance and some others. Therefore, studies aimed at
improving the design of rotary-type machines seem to
be very important. To achieve this goal some
theoretical and experimental studies and lab and field
tests of the modernized four-row shredder have been
carried out. When studying methods of mathematical
analysis and elements of classical mechanics were
used. Some modern methods were applied in the lab
and field tests. The modernized haulm shredder BD-4
was tested at JSC “Avangard” in Ryazan district
