Abstract: To explore strategies and practice for advancing digital construction of Agricultural Power Equipment Application Technology course through virtual reality（VR）technology, existing problems in traditional professional teaching were identified．These included insufficient digital teaching resources, abstraction and difficulty of complex mechanical principles, and high equipment operation costs, have restricted students' learning effectiveness and practical ability cultivation．Focusing on digital innovation in curriculum digitization, cutting-edge technologies such as 3D design software, WebGL technology, 3D, and VR engine technologies were employed to construct and develop digital resources for Agricultural Power Equipment Application Technology course．This realized structural cognition, disassembly simulation, and fault diagnosis of agricultural power equipment, breaking through temporal and spatial limitations of traditional teaching．This approach provided practical reference for digital construction of agricultural equipment courses in vocational education．
