Studies & Degrees in Heavy Equipment Maintenance

Heavy equipment maintenance is the trade of keeping large machines working: excavators, bulldozers, cranes and graders on construction sites and in surface mines, tractors and harvesters on farms, and railway rolling stock. The US Bureau of Labor Statistics (BLS) describes the people who do this work as technicians who inspect, maintain and repair vehicles and machinery used in construction, farming, rail transportation and other industries.

Students learn how the main systems of a machine work and how to find faults in them: diesel engines, hydraulics, transmissions and powertrains, brakes, and electrical and electronic systems. Diagnosis with computers and test instruments is a large part of the job today, next to workshop skills such as welding and machining.

Qualifications and levels

This is a vocational subject. Most programmes are short and practical, and almost all schools in this directory that teach it are in the United States.

  • Certificates. According to the BLS, vocational schools and community colleges offer programmes in diesel technology or heavy equipment mechanics that last one to two years and lead to a certificate of completion.
  • Associate degrees. These generally take two years. One example is the Heavy Equipment/Diesel Technology Associate of Applied Science at Linn-Benton Community College in Oregon, with 92-93 credit hours and courses in electrical and electronic systems, powertrain systems, mobile hydraulics and diesel engines.
  • Bachelor's degrees. These are rare. Ferris State University in Michigan has taught a Heavy Equipment Technology associate degree since 1959 and added a bachelor's degree, Heavy Equipment Service Engineering Technology, in 1991. The university states that it is still the only bachelor's degree of its kind in the United States. It adds failure analysis, troubleshooting techniques and product design to the mechanical, electrical, electronic and hydraulic subjects.
  • Spain. The closest official qualification is the vocational training (FP) title Técnico en Electromecánica de Maquinaria, a grado medio cycle of 2,000 hours. It trains students to locate faults in the mechanical, hydraulic, pneumatic and electrical-electronic systems of machinery.

A school-leaving qualification is the usual entry requirement. The BLS notes that most technicians have a high school diploma or equivalent, and that new technicians usually become fully qualified after three to four years of work. Some manufacturers also certify technicians in their own equipment and repair methods.

Where to study

SpainExchange lists six active schools for heavy equipment maintenance, all in the United States: Ferris State University (Big Rapids, Michigan), Linn-Benton Community College (Albany, Oregon), Lansing Community College (Lansing, Michigan), Western Wyoming Community College (Rock Springs, Wyoming), Eastern Maine Community College (Bangor, Maine) and Shelton State Community College (Tuscaloosa, Alabama). Five of the six are two-year community colleges. Teaching is in English.

Programme names differ from school to school. Many colleges combine the subject with diesel technology: Western Wyoming Community College, for example, presents its Diesel and Heavy Equipment programmes together. When comparing schools, look at the machines and engines students actually work on, the length of any work placement, and industry accreditation. The AED Foundation, the non-profit foundation of the heavy equipment distribution industry, accredits college programmes in this field; the Ferris State programme is one that reports this accreditation.

Careers

The BLS distinguishes three specialisations. Mobile heavy equipment mechanics repair and maintain construction and surface mining equipment, and most work for governments, equipment rental and leasing shops, and large construction and mining companies. Farm equipment mechanics service tractors and harvesters, mostly in dealer repair shops. Rail car repairers service locomotives, subway cars and other rolling stock.

In the United States, the BLS projects employment of heavy vehicle and mobile equipment service technicians to grow 7 percent from 2025 to 2035, with about 20,300 openings each year. In Spain, the official job profiles for the Electromecánica de Maquinaria title include mechanic for agricultural machinery, for extractive-industry machines and for building and civil engineering machines.

Frequently asked questions

How long does it take to train as a heavy equipment technician?

Certificate programmes last one to two years and associate degrees generally take two years, according to the US Bureau of Labor Statistics. Technicians usually become fully qualified after three to four years of work.

Do I need a university degree?

No. Most technicians enter with a high school diploma and a vocational certificate or associate degree. A bachelor's degree exists at Ferris State University but is the exception.

Is heavy equipment maintenance the same as diesel technology?

The two overlap, and many colleges teach them in one programme. Diesel technology centres on trucks, buses and diesel engines; heavy equipment maintenance centres on construction, farm, mining and rail machines and gives more weight to hydraulics.

Can I study this subject in Spain?

Not at the schools listed here, which are all in the United States. Spain's public vocational system offers the official title Técnico en Electromecánica de Maquinaria, a grado medio cycle of 2,000 hours.
