Choosing between diesel mechanics and heavy equipment mechanics, or thinking about switching? This side-by-side uses the federal government’s BLS OEWS national data, May 2025 for pay and job counts and BLS Employment Projections, 2025–35 for growth, openings and typical entry requirements. BLS occupation titles: “Bus and Truck Mechanics and Diesel Engine Specialists” (SOC 49-3031) and “Mobile Heavy Equipment Mechanics, Except Engines” (SOC 49-3042). More detail: Diesel Mechanics (BLS) and Heavy Equipment Mechanics (BLS).
Pay side by side
| May 2025 | Diesel Mechanics | Heavy Equipment Mechanics |
|---|---|---|
| U.S. jobs | 289,960 | 176,600 |
| 10th percentile (annual) | $44,530 | $46,820 |
| 25th percentile | $50,540 | $56,970 |
| Median (annual) | $61,770 | $65,510 |
| Median (hourly) | $29.70 | $31.50 |
| 75th percentile | $75,470 | $79,270 |
| 90th percentile | $88,740 | $94,460 |
| Mean (average) | $64,320 | $69,240 |
Percentile wages: for example, 10% of workers earn less than the 10th-percentile figure. OEWS wages exclude overtime, tips and most bonuses.
Outlook and how you get in
| BLS Employment Projections | Diesel Mechanics | Heavy Equipment Mechanics |
|---|---|---|
| Projected job growth, 2025–35 | 3.6% | 6.7% |
| Openings per year (avg.) | 24.4 thousand | 15.0 thousand |
| Typical entry education | High school diploma or equivalent | High school diploma or equivalent |
| Work experience in a related job | none | none |
| Typical on-the-job training | Long-term on-the-job training | Long-term on-the-job training |
Openings include jobs that open up when workers retire or change occupations, not just new positions, which is why a field with slow growth can still hire a lot of people every year.
Where each job pays best
The three states with the highest median wage for each occupation (BLS OEWS state data, May 2025):
| Rank | Diesel Mechanics | Heavy Equipment Mechanics |
|---|---|---|
| 1 | Hawaii – $80,080 | Alaska – $82,670 |
| 2 | Washington – $77,900 | Nevada – $79,860 |
| 3 | Alaska – $75,580 | Minnesota – $79,370 |
By industry, diesel mechanics earned the highest median in Utilities ($99,210) and heavy equipment mechanics in Professional, Scientific, and Technical Services ($87,320), counting sectors with at least 1,000 jobs in the occupation (BLS OEWS industry data).
Which should you pick?
- Look past the median. Compare the 25th and 75th percentiles too: they show what a typical early-career and an experienced worker earn in each field.
- Count the cost of entry. The education and training rows above tell you how long it takes to start earning. A longer path can still pay off if the pay gap is large.
- Check your area. State pay differs a lot from the national figure; use the state table and your local job ads before deciding.
- Already in one of these jobs? If your pay is below the 25th percentile for your field, that is a concrete number to bring to a raise conversation.
