Therefore, the teaching system of the course should be upgraded and innovated.

This teaching system strives to lay a solid theoretical foundation for students’ professional knowledge, and also tries to create conditions for training students’ practical ability. Moreover, it aims to help the students develop the habits of self-learning and conscious innovation, which are needed in the agricultural machinery industry to be a professional expert with solid foundation and excellent skills.
