Abstract

Driven by global agricultural mechanization and green low-carbon transformation, hybrid tractors have become a key focus in agricultural machinery competition due to fuel economy and operational adaptability. Using literature review and comparative analysis, this paper summarizes global and domestic technological development and characteristics of typical models. It analyzes three core power topological structures, compares energy configurations and management strategies, clarifies applicable scenarios and pros and cons of different routes, and points out bottlenecks in power coupling, energy storage and control, as well as industrial dilemmas like high costs and poor supporting facilities.
