Description
This article deals with the rules of observance of agriculture technology requirements for the production of potatoes in particular. On the example of the combine PDA 1.2, we have considered the places having the greatest damaging effect on roots. One can also find a summary procedure for calculating the probability of defective products

DIAGNOSTICS OF THE MOBILE AGRICULTURAL TECHNIQUES USING THE DEVICE OF THE «SAMTEC» COMPANY
DescriptionThe issue of the article is the procedure of diagnostics of the mobile agricultural techniques based on the implementation of the automatic control electronic systems. In particular, a ternary circuit is being created for the analysis of diagnostic protocols, which allows facilitating the specifying of the protocols, including compiling of documents describing the basic parameters, the structure and the constants of diagnostic protocols

METHODS OF EFFICIENT MONITORING RATE OF THE MOBILE AGRICULTURAL EQUIPMENT BRAKE SYSTEM
DescriptionThe article presents the methods of efficient monitoring rate of the mobile agricultural equipment brake system based on the usage of methods of the theory of relativity. We have considered the methods of the brake gear monitoring rate according to the acceptable level of reliability, to the technical index and change logic of the technical parameters state and economic-probabilistic method. From the above-stated one can see, first, that diagnosing usage is the development of maintenance preventive strategy. Second, its practicability and the ways of realization are determined by technical and economic calculations

A METHOD OF CONSTRUCTING A MATRIX OF STATES OF THE DIAGNOSTIC PARAMETERS OF BRAKE SYSTEM OF A CAR
DescriptionThe article describes the method of determining the list of rational diagnostic parameters of the brake system of a vehicle using the theory of probability and mathematical statistics. The problems determining the statistical probabilities of failures on objects considered a run; mathematical models (regression dependence) the probability of failure of run; A statistical evaluation of the significance of the coefficients of regression models; verification has been made on the adequacy of the regression models; the probabilities of possible states of objects. On the basis of the construction and analysis of structural- effect model brake system information and calculates the importance of each monitored parameter using the notion of information entropy, determine the parameters to be diagnostic, and builds a matrix condition of brake systems for non-destructive testing, in order to move on maintenance and repair of the actual state

Description
Based on the previous investigations we have underlined the need to increase fruit and vegetables preservation quality while transporting them from the producer to the consumer at the expense of improving the road transport operation for its intended purpose. We have made a conclusion about the need to develop strategies for maintenance and repair as for the actual technical state at the expense of developing the diagnosis system based on the development of a math model of changing the technical state of the diagnosis object, developing a method of rational set of objects to be diagnosed and determining the technical state optimal control frequency. We have confirmed that the above mentioned is possible when considering the system of technical operation of road transport as an organization-production system and applying the engineering-cybernetic approach to improve this system. We have considered the basic requirements for the efficiency indexes when investigating and improving the operation system that will allow achieving the aim we have had and can be described mathematically. We have made a conclusion about the urgency of the issue we studied and the possibility to develop the efficient operation system of road transport based on the provided criteria

Description
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

CHALLENGES AND TECHNICAL SOLUTIONS OF USING HIGH-PERFORMANCE TRANSPORT OF AGRICULTURAL MACHINERY
DescriptionMaterial and technical resources form a large part of the costs in agricultural production and determine the level of intensity of agriculture, productivity and competitiveness of the industry. The most important role in agricultural production is played by transport operation, from productivity and quality of which directly depends the volume and the grade of final products. More preferable is tractor transport, particularly for on-farm transport, taking into account the impact of navigation systems on the ground. 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. The reduced controllability leads to an increase of damage to transported agricultural products owing to increased oscillatory processes in the system of "road – trailer – tractor – operator" when driving on-farm trails, deteriorating the smoothness and braking properties. Especially sharp these questions relate to transportation of easy-to-damage agricultural products at farm transportation. The feature of data traffic lies in the sharp drop in grade products (products receive numerous mechanical damages, deteriorating its quality, and lose marketability and accordingly reduced its cost). Influence on fruit and vegetable products of unfavorable factors can lead not only to a dramatic loss of quality at the time of transportation, but also reduce the resistance during further storage. To solve the problems emerging when increasing the saturation of tractors, 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
