What is a Heavy Equipment Mechanic?
A heavy equipment mechanic inspects and repairs large mobile machines. They work on hydraulics, transmissions, brakes, electrical systems, and undercarriages. Many work for Caterpillar or Komatsu dealers or construction and mining companies.

Your Responsibilities:
- Diagnose problems with hydraulics, engines, and electronics
- Repair and replace large parts
- Service undercarriages and tracks
- Do preventive maintenance
- Make field repairs at job sites
- Use cranes and hoists to move parts
- Test equipment after repairs
- Keep service records
You keep the biggest machines in North Dakota working.

Training in North Dakota
No state license is required. Dealer-sponsored programs and diesel programs are common paths. Registered apprenticeships are also available in ND.
Training Pathways:
- Dealer-sponsored AAS (about 2 years): Caterpillar or Komatsu programs with paid internships.
- Diesel technology program: Leads to heavy equipment jobs too.
- Registered apprenticeship: ApprenticeshipND lists Construction Equipment Mechanics.
Where to Train in North Dakota:
- ND State College of Science (Wahpeton) — Caterpillar Dealer Service Technician, AAS
- ND State College of Science (Wahpeton) — Diesel Technology – Komatsu, AAS
- Williston State College (Williston) — Diesel Technology, AAS or certificate

Before You Start: High school diploma or GED. A valid driver's license. A CDL may be required later. You will likely need your own tools.
Tip: Start with financial aid, scholarships, and any help an employer offers — that is where the money starts. After that, ask a career counselor or Job Service North Dakota whether WIOA or other programs can help with what is left over, like training, tools, work boots, or exam fees. What can be paid for depends on the program and on your own situation, so ask before you sign up rather than after. Registered apprenticeships let you earn a paycheck while you learn — see jobsnd.com/job-seeker/apprenticeships for ND programs.
