I don't know about other states, but in Ohio if a vehicle is never driven on a public road, it needn't be licensed, and no drivers license is needed to operate it. The jeep on the golf course where I used to work was not licensed; the truck used by the caretaker at my gun club is not licensed.

In California, all motor vehicles (not necessarily farm equipment) must be registered, even if they are inoperable.
