The paper describes the relevance of the creation of a supporting laboratory for testing compliance with the Organisation for Economic Co-operation and Development (OECD) Tractor Code for agricultural and forestry tractors in conditions of international integration. The paper provides the international requirements for tractor products according to the OECD Tractor Code regulations. A set of activities for the creation of a supporting laboratory is presented. The study lists which methodologies need to be developed for testing tractor units and assemblies. It shows the procedure for validating tests at the OECD. It is pointed out that the development and use of digital services is necessary to ensure a leap forward in the development of integration in the field of technical regulation.

The article discusses modern technologies for diagnosing the technical condition of agricultural automotive equipment on the example of a John Deere tractor. A description of the John Deere tractor and electronic systems is given. Modern tractors are equipped with microprocessor-based control systems with diagnostic capabilities. This makes it possible to timely inform the operator about possible malfunctions of the working systems of the tractor, for example, the engine or brake system. The system of digital communication and control of the electric devices of the vehicle — the CAN interface — allows you to collect data from all devices, exchange information between them, manage them.

Two main functions of the machine are given, consumer and technical. The application of the law of conservation of energy in describing the energy balance of a machine element is shown. An extended concept of the technical condition is given in relation to the machine, the parameters of the technical condition are substantiated. The relationships between the technical condition and serviceability and serviceability, as well as the relationship between the serviceability of a machine element and its efficiency, have been determined. The possibility of representing a technical state in the form of a «Class» in object-oriented programming is revealed.

The article provides performance indicators of internal combustion engines (ICE) of autotractor equipment by means of information exchange via CAN of tyres between electronic control units. The device is classified depending on its fi eld of application, as well as the list of components, operation of which is provided by application of CAN bus. Main values and performance indicators of ICE are indicated when using electronic control units: ACU, CAB, CCU, CLC, ECU, HCU, ICU, PTQ, TEC, VLC.

The paper reflects the nature of the main technological measures that are carried out at specialized enterprises (sites) for processing waste disposal of self-propelled machines in the agro-industrial complex. Waste generation occurs at all stages of the life cycle. The product life cycle includes a number of stages, each of which involves the use of specific types of work, in the course of which there are production and consumption waste (hereinafter — waste). Considering the full life cycle of the machine, it should be understood that the production stage of the machine can last for a long time. But the time characteristic of making a particular machine at this stage will be equal to the time interval associated with making a particular instance of the machine.
