Because we do not have one.
The “bloody Tractor” was a very kind gift from New Holland a few years ago.
Maybe you would like to donate an aircraft Tug?
This place is littered with them, I know 2 people with one aircraft & 3 tugs. Howard has a David Brown one that’s been resto-modded & looks quite tasty. Might have to stash one in a container next time an aircraft goes East 😉
I see them looking abandoned around the airfields quite a bit since a certain POTUS destroyed the private aviation business.
