Do you have any links to that huge traction engine?
Here are 2 of my youtube videos that have really taken off in the past few weeks from the unveiling in Andover, SD last September. My 3 year old can be heard quite a bit in them

I have some pictures and will post my trip report in the full-size section of the forum this evening...
If you have seen a 110 Case, those have 7 foot diameter rear wheels, these are 8 feet.
