tractor

This word evokes images of heavy-duty utility and ruggedness. It is strongly associated with rural life, farming, and industrial labor. While most people think of the red or green machines in a field, the term applies to any vehicle whose primary purpose is to pull something else rather than carry passengers. In modern usage, it carries a connotation of reliability and brute force. It is rarely used in a casual or urban context unless referring to specialized construction equipment or a specific type of propulsion system in aviation.
