What Is Heavy Diesel Mechanics?

Heavy diesel mechanics is the repair and maintenance of heavy diesel-powered equipment, such as trucks, buses and farm equipment, by mechanics and similar technicians. Heavy diesel mechanics work in many settings, including trucking, construction, logging, and farming. Many technicians are graduates of certificate or degree programs in diesel technology, such as an Associate of Applied Science in Diesel Technology program. Schools offering Diesel Mechanics degrees can also be found in these popular choices.

Industry Overview

The durability and efficiency of diesel-powered engines makes them ideal for use in vehicles that endure a lot of wear and tear, including buses, trucks, trains, cranes, locomotives, cargo ships, farm tractors, and bulldozers. Lots of equipment runs on diesel engines, such as oil rigs, hydraulic systems, and farming equipment.
