Each Mighty Machines episode focuses on a specific type of heavy equipment or work environment. The machines talk to the viewers. Documentary footage of actual machines in action doing their day-to-day work is presented with voiceovers of the machines addressing the viewers. The audience is invited to follow the machines during a typical day. The machines explain their abilities and duties in detail over the course of the episode. The machines talk to each other too. Each machine is given its own personality and they often have conversations with each other as they work. Unlike most documentary-style shows, there is no external narrator.
