Potato has been and remains one of the five world's
most important crops. For nearly two hundred years
potato in Russia is the "second bread". This is one of
the so-called social products. Over the past 20 - 25
years of potato farming in our country, there have been
significant changes, both positive and negative. Today,
potatoes are grown in different soil and climatic
conditions in more than one hundred countries around
the world, including the desert oasis and beyond the
polar circle. Potato cultivation Center recently has
moved to Asia. In our time, the leaders of potato
production are China, Russia, India, the US and
Ukraine. Over the past few decades the number of
produced potatoes has increased by 41% and the area under potato planting only 9.5%. From the above data
it is clear that the world potato economy in recent
years has got significant changes, indicating that the
timeliness and relevance of the material in this article
is true
The article presents native and foreign bench-top
and board methods to test the automobile break
systems. One can find information about some
native trailer-break stands. We have analyzed their
advantages and drawbacks such as low information
capacity, high diagnostics processing time, low
quality of regulation and maintenance operations
due to big influence of the operator’s experience,
his knowledge and individual characteristics, and
great instability of manual test modes on the results
of the investigations. To remove these shortcomings
they have had some experiments at MADI in order
to develop the module to the brake qualities stand.
When using it one can have automatic diagnoses
and flow chart is presented in the article. Due to the
existing vehicles’ state inspection mode and
diagnostic means in our country there appeared new
stands for brakes control. One can attribute to these
devices a range of brake qualities stands developed
and produced at Novgorod plant GARO. These are
STS-3, STS-10 and STO series stands for cars,
trucks, buses and micro-buses. The article also
presents some foreign stands used in Russia such as
universal brake stands STM by META firm, the
break stand IW7 Eurosystem by MAHARUSSIA
firm. We have presented in the article the results of
the analysis of simple and complicated board means
of diagnosis as “Eftor-2”, “Effect”
The development of agricultural production inevitably
entails an increasing volume of traffic and a turnover of
goods. Therefore, the issues of increasing transport
efficiency, reducing the price of transportations and
improving productivity acquire great importance.
In most cases, supersize dump trucks used for the
transport of agricultural production have much more than 6 tons axle load. Thus, these cars need to have
roads with improved surface to each field, which
undoubtedly is a significant drawback. Because of the
extra movements of harvester dump trucks on the
turning strip at the end of the field, it increases expenses
of damage and loss of crops and the arrival of heavy
machinery in the field leading to soil compaction, that
in the end affects the future crop. Transportation of
agricultural commodities is most effective when the car
arrives directly to the harvester machinery. Such
vehicles must have sufficient abilities and capacity of
the body comparable with the volume of a combine
hopper and has no significant impact on soil sealing.
With this method, harvesters do not make extra
movements and are not idle. Basic requirements for
vehicles used in the harvesting potatoes, are in a more
productive use due to increasing the capacity and
reducing downtime when loading or unloading and
minimizing the level of damage to other tubers. For the
transportation of agricultural products there is a
different transport technology, which either do not fully
meets the requirements of transportation of highly
fragile product, or has a significant cost. Therefore, we
require a specially equipped vehicle bodies, with a
competitive ability in the range acceptable to the
Russian Federation. As one of the innovative
developments, this article proposes a tipper body of the
vehicle for transportation of highly fragile agricultural
products. The proposed design solution for the tipper
ensures a uniform unloading of transported products
from the vehicle body and prevents arching issues
Material and technical resources form the bulk of the
cost in the production of agricultural products and
determine the level of intensity of agricultural
development, productivity and competitiveness of the
industry. The most important role in agricultural
production has been given to transport operation, as the
performance and the quality of the implementation of
which depends directly on the amount and the grade of
the products. On intraeconomic transportation in the
APC RF, along with the car we widely use tractor
trucks. Unfortunately, in most cases for the
transportation of agricultural goods we use supersize
trucks, including construction purposes, with a high
axle loading. These vehicles need roads with improved
coating to each field. Here we may note substantial
shortcomings of transportation. Because of the
unnecessary displacements from combines to dump
trucks to the end of the field, the costs and the losses are increasing and the arrival of heavy machinery in the
field leads to soil compaction, which ultimately affects
the future harvest. The successful implementation of
agricultural work is strongly associated with the timely
and volume movement of a variety of materials, such as
animal feed, fertilizers, construction, and other loads. A
lot of these works needs roads; nevertheless, the quality
of agricultural roads and field work significantly affects
the timely and high-quality forage. Thus an important
part of any machinery tractor fleet of agricultural
production is taken by the presence of modern cars,
tractor-trailers and semi-trailers. Continuous growth in
the saturation of tractors carried out around the world,
improves the performance of tractor transport aggregate
by increasing their capacity and speed, either on the
road or in the field. However, if you increase the
saturation of tractors, it encounters problems related to
the deterioration of the controllability of the tractor and
transport unit. To address emerging when increasing the
saturation of tractors problems, we have proposed
devices, allowing reducing negative impact on the
production of elevated oscillatory processes, to increase
the permeability and straightness of movement of
tractor-transport unit
The article presents a technical diagnostics of a car as a complex of goals and tasks connected with
trouble-shooting of mechanisms and systems in
order to eliminate them. We have considered the
stages of computer diagnostics of different
automobile systems such as diagnosing the engine,
the brake system, steering and suspension. We have
analyzed their components, the ways of troubleshooting
and elimination recommendations. The
article presents the main troubles transferred from
the electronic control unit. The article also presents
the stages of diagnosing the engine including
external examination, listening to abnormal noises,
checking the operating fluids and the engine
management system, diagnosing the basic engine
systems and checking the cylinders being filled.
The article contains the list of main troubles and
their reasons. One can also see diagnosing the brake
system, its defects and remedies. The article
presents diagnostics and repair of the suspender and
graphics describing the check of the dismantled
shock strut at the stand and tests of the shock strut
without being dismantled. We have analyzed
computer diagnostics and the problems it solves
The role of transport in agricultural production
is significant. It is the connecting link in the
technological chain of the agro-industrial
complex (of the APC). On-farm transport in the
APC together with cars and tractor transport are
widely used. The rationality of the use of
wheeled tractors for farm transport substantiates
the possibility of their movement on asphalt and
on dirt roads. The specific gravity of the tractor
transport in the domestic agriculture is 22-27%
of the total volume of transport and 50-60% of
the volume of farm traffic. A high level of use of tractor transport has been observed in the
countries of Western Europe and the USA. In
the farms of leading countries of Western
Europe (Germany, Italy, France, etc.) about 70-
90% on-farm transport of agricultural goods is
done by tractor transport. Tractor transport in a
live environment is running on roads with
varying terrain, a wavy profile cover, on soils
with different hardness and humidity. When
driving vehicles at high speeds, the trailer is
wobbling from side to side, constantly
accompanying tractor transport during its
operation. As a result, it is bad for propulsion,
transmission, and it deteriorates the dynamic
performance properties of equipment, working
conditions of the operator. To reduce the
amplitude of oscillations of the trailer, the
operator is forced to work strenuously with the
steering wheel or to slow down the speed,
which in turn affects operator fatigue, as well as
the performance and maneuverability of the
vehicle. Thus, advanced technologies in
electronics, sensor technology and software will
determine the nature of agro-technical
innovations and will lead to increased
automation of business processes in crop
production with the aim to organize the work
more effectively, efficiently, accurately,
environmentally friendly and economically
feasible. When working with intelligent
technologies, understanding the development of
high-tech, precision engineering requires a
revision to the personnel policy and education
in agriculture, which should be based on the
relevant organization of farms and their proper
new type engineering solutions
Due to the deterioration of the ecological situation
in the world, population tends to eat organically
grown foods that are grown either without or with
minimal use of chemicals. The development of
agriculture in this direction leads ultimately to
organic agriculture. To improve the competitiveness of this direction, we need more
effective agricultural machines, especially in the
last phase of cultivation, namely at the stage of
harvesting. One of the most difficult scientific and
technical problems with the mechanical harvesting
of potatoes is not letting vegetable impurities and
tops to fall down in the hopper with the potato
tubers, which among other things will improve
operational efficiency technology. The article
reviewed the various methods for removing the
tops, as well as their advantages and disadvantages.
The article makes a conclusion about the need for
potato top separators in harvesting machines. We
have also considered a promising device for
removing haulm, a conveyor with flexible fingers
on the bars and the clamping beater. Тhe most
short-lived structural element of the device for
removing haulm, reducing reliability of the device,
is flexible fingers mounted on rods. We have
proposed to use polyurethane as a material for
manufacturing flexible fingers
One of the promising directions of development of
agriculture of the Russian Federation is to increase
the production, improve the quality and decrease the
cost of potato cultivation. Annual cleaning is one of
the most intense and costly in transport and
technological processes. Potatoes - blending high
culture and very picky about cleaning. The highest
yields and income from potato production get where
embedded technology to optimize energy and labor
costs. The main (though not only) the special
technical means used during machine harvesting
potatoes, are potato harvesters. The main problem
when cleaning is a problem of balancing conflicting
requirements to the process and possibilities of
agricultural machinery. Including increasing the
purity of the tubers in the container with one hand,
minimization of losses and damages of tubers on the
other hand, when the performance of equipment. In
this article we propose a circuit-design solution
separating the working body of the potato harvester
that allow for cleaning to significantly reduce the
amount of traumatized potatoes in the process of
separating soil and vegetable impurities, creating the
preconditions for the elimination of damage to the
tubers on the hard side of the working bodies of
harvesting machines. Informed choice and timely use
of plug-in modules (separating working bodies) in
modern potato harvesting machines at work in
specific climatic conditions allows them to fully
match the list of regulated agronomic requirements.
Thus, the creation of new science-based technical
solutions for a separation of the organs of potato
harvesters is an actual scientific-technical task, which
makes a significant contribution to the development
of the country
In the world, recycling processes have recently
become more common in order to save material and
energy resources. Currently, in connection with the
level of motorization, there grew a problem of
recycling waste tires and their elements which is of great importance for many regions of the country.
Decommissioning worn tires is a source of
environmental pollution, bearing the prolonged
character; they are not a subject to biological
destruction and require constant increase of storage
facilities. There is a continuous accumulation of used
tires and we can recycle only about 20% of their
amount. Worn tires represent very large-capacity
products of polymer-containing waste, virtually
resistant to natural degradation. Therefore, the
problem of processing and secondary use, emerged
from the operation of tires is of great economic and
environmental significance. However, the worn tires
are a source of valuable secondary raw materials:
rubber, soot (essentially pure carbon), metal and
synthetic cord. 90% of all waste of rubber are tires
and represent a vast reserve of raw materials. In the
emerging in the industry nonrenew- material
resources the efficient use of secondary raw materials
is of great importance. There are improved
technologies for processing rubber goods, and the
equipment used for it
In recent years, in many countries around the
world, much attention is paid to the issues of
ensuring of rational use of energy resources,
due to a number of objective factors, chief
among which are: the lack of own energy
resources to meet domestic energy needs; the
sharp increase in the cost of production and the
production of energy resources; further growth
in energy needs; the presence of large potential
opportunities to reduce unproductive losses of
fuel and energy. In the world, the challenge
now is to ensure a gradual but steady transfer of
the economy on energy saving way of
development. To achieve the goal of reducing
energy costs we might use two ways: firstly, the
widespread introduction of energy saving
technologies, and secondly, the reduction of
material production, improving its quality and
service. In agriculture, the improvement of the
technological process can be carried out using
new tillage methods, improving the
organization of production and tools. Further
development of mechanization in agriculture
will contribute to further growth of
electrification in the agricultural sector, which
will significantly reduce the use of the most
expensive and limited energy resources. The
article offers a technique of the estimation of
the efficiency of consumption of energy in
agricultural production. In order to compare the
efficiency of machines in the cultivation and
harvesting of potatoes, there was conducted an
energy assessment of the operations of modern
technology. As variables, there were
investigated different operation modes of the
machine: working speed and working width,
depth of stroke of the working bodies. In the
process of evaluating energy operations,
modern technology to prepare the soil for
planting potatoes was determined humidity,
mechanical composition and soil type. As a
main factor in the analysis of technological
methods, we have taken the overall specific
energy consumption and specific energy
consumption for the digging below tuber
formation. Analysis of theoretical researches of
agricultural machinery has led to the conclusion
that the energy cost of implementing the
technological process in the machines of
different designs varies
