A mechanic is a skilled tradesperson who uses tools to build, maintain, or repair machinery,[1] especially engines.

Formerly, the term meant any member of the handicraft trades, but by the early 20th century, it had come to mean one who works with machinery.

There are also mobile mechanics who work on heavy equipment that will come to you if there is an issue that must be resolved at the location of the machine.

Mechanics may be separated into two classes based on the type of machines they work on, heavyweight and lightweight.

Countries like Canada have a governmental certification body that tests and maintains automotive mechanics' qualifications.
