The intensive development of agricultural engineering and agricultural technologies requires a future engineer to have a thorough knowledge of the structure and purpose of modern agricultural machinery. In the process of training future engineers in the educational process of higher agricultural educational institutions, a problem has arisen, which is the lack of such equipment as training models. Smart technologies of Industry 4.0, such as artificial intelligence, digital twins, virtual and augmented reality, allow to optimize the educational process, increase its efficiency and reduce the time spent on learning due to a new stage of automation. The purpose of the article is to highlight the main stages of VR application development and the possibilities of using virtual reality to study the structure of tractors. The main object of study is a tractor, so the issue of developing a digital twin was resolved separately. The VR application was developed as a smartphone program using a Google Cardboard headset, and the Unity game engine was chosen as the development environment. The main scene shows a hangar with electronic models of a John Deere 6195M tractor and a virtual avatar. One model of the tractor is disassembled into separate components to study its internal structure. A script was written for the virtual avatar to allow it to move. In particular, the avatar moves when the camera is tilted down to a certain angle. Red markers are placed near the tractor nodes, which interact with the avatar’s sight and display information panels. The information panels tell about the name of the node, its purpose, and technical characteristics. The use of the program we developed in the educational process has shown that higher education students liked the process of gaining knowledge in a game form, but it should be noted that the movement of the virtual avatar sometimes caused dizziness in some users.
