Production internship is an important teaching part of agricultural mechanization and automation majors in higher education institutions. It plays an important role in cultivating students'engineering abilities and promoting their employment and career development. However, there are still many problems in the production internship of agricultural machinery majors, which are not conducive to the cultivation of students'engineering abilities. Based on the current situation of agricultural machinery major production internships, this article analyzes the specific problems in cultivating students'engineering abilities during production internships, including insufficient attention from students to production internships, lack of high-level guidance teachers, insuffi-cient depth of internship content, loose organizational forms, and lack of targeted practical assessments. Subsequently, the article proposed teaching reform measures such as tapping into students'intrinsic motivation, hiring corporate mentors, keeping up with industry needs, segmenting internship plans, and optimizing assessment content, in order to increase students'attention to intern-ships, improve the level of guidance teachers, expand internship content, optimize internship organization forms, and improve assessment efficiency. Teaching practice was conducted, and good results were achieved. This study has certain reference value for the production internship teaching of other similar courses.
