Purpose. Improving the methodology of substantiation of the selection of energy means for performing technological operations in walnut orchards, which is the basis for further determination of their rational parameters.
Methods. The research uses the principles of systems analysis, as well as monographic and graph analytical methods.
Results. Performing technological operations in walnut orchards requires special features from tractors: movement in the rows of the garden without damaging the tree crown; providing aggregation of symmetrical machines and with lateral displacement; availability of a universal hydraulic system for the drive of working bodies; to provide statistical and dynamic stability when hanging agricultural machines.
To achieve this goal, it is advisable to consider the tractor on a two-parameter classification system, ie the transition from traction to traction-energy concept, take into account the traction force of the tractor on the hook and the effective power of the tractor engine.
To substantiate the parameters of the energy means of performing technological operations in perennial walnut plantations, an algorithm is proposed that allows taking into account the technical and technological parameters of MTU. It is developed on the basis of information on the technologies of growing walnuts available on the world market and technical means for their implementation. It is developed on the basis of information about the technologies and technical means of walnut production available on the world market and allows carrying out their system-structural analysis.
The identification of domestic and foreign energy remedy available on the market to ensure the technological process of walnuts production was carried out and correlation-regression analysis was performed, which allowed establishing the relationship between tractor cost and their parameters: engine power, operating weight.
The proposed dependences make it possible to substantiate the rational (optimal) parameters of the technical support of the entire technological process with different subject-production characteristics.
Conclusions. Based on the analysis of existing methods of substantiation of parameters of energy remedy for technological operations of agricultural production it is established that specialized methods that would take into account the peculiarities of walnut production absent. A new technique has been developed that will increase the efficiency of substantiation of energy parameters during the technological operations of walnut cultivation.
The identification of available on the market energy remedy, machines and tools for technological operations of walnut production is carried out and their parametric and cost indicators are established. Based on these data, a regression analysis was performed, which made it possible to establish the relationships between price and their parametric indicators.
