How To Become a Heavy Equipment Mechanic: FAQs

What training and education do I need?

Most employers require a high school diploma or equivalent. Entry-level workers receive on-the-job training.

Employers often look for postsecondary specialization in diesel technology, heavy equipment mechanics or small engine repair. Technical schools and community colleges offer certificate programs that cover diagnostics, electronics as well as hands-on training. Certificate programs typically last from 12 months to two years. An associate degree in diesel technology or heavy equipment mechanics will take two years. 

Some companies and trade unions offer internships, so you can learn while you earn. (Jump at an internship opportunity if you see one.) Most companies offer some form of on-the-job training for entry-level mechanics to get familiar with the company’s machines. The length of training to become fully qualified varies.

Military experience in heavy duty machine repair may also be beneficial.

Equipment manufacturers also offer specialized training, which allows mechanics to learn new technology or how to fix specific equipment. In this line of work, it pays to invest the time in continuing education because the equipment and the technology is always improving. (Besides, many employers will cover this expense and give you the time away from work to learn new skills.)
