A tractor that is capable of carrying a driver (or driverless), and also capable of carrying other things is definitely a vehicle. If it is battery-powered, it an electric vehicle. The company making the title EV is Monarch Tractor, and they are on the other side of Livermore, CA where I have lived for over 30 years.
If you are curious about the “AI” in the title of this post, Monarch Tractors also makes a software package called Wingspan AI. This package does much more that control tractors, and this post is about Monarch’s Tractors and their AI.
