Two-Tonne is a big powered cab unit who likes to get everything just right. A very adaptable heavy goods vehicle, he can haul heavy materials and equipment on different types of trailers, including Bob's mobile office. His experience and knowledge is invaluable to Bob and the team, and so the machine team often look up to him in admiration.
- In the US, Two-Tonne does not have a catchphrase along with Wendy and Leo.
