The relevance of the work is driven by rising energy resource prices and tightening environmental requirements, which necessitate the implementation of resource-saving solutions in agro-industrial complexes. The objective of the research is to classify and analyze contemporary methods for improving the energy efficiency of hydraulic circuits in tractors and combines, including through the use of advanced components, intelligent control algorithms, and innovative technologies for repair and modernization. The methodological foundation comprised a review of scientific publications, synthesis of advanced practical experience, and a comparative investigation of various hydraulic system architectures. The results demonstrated that the application of Load-Sensing (LS) and electrohydraulic (EH) control systems can reduce fuel consumption depending on the operating mode. The economic and technological justification for employing progressive methods of restoring worn components is also shown, contributing to reduced operational costs and maintenance of the hydraulic system near its optimal performance. Based on the obtained data, a comprehensive approach has been formulated, envisaging the combination of installation of modern assemblies and precision restoration of components. The information presented in this work will be of interest to designers, service engineers, and managers of agricultural enterprises focused on improving production profitability and environmental sustainability.HAL open archive record: https://hal.science/hal-05855805 (hal-05855805)
