Tractors are not titled. Automobiles and trucks are. When you sell an auto, you record the mileage at time of sale and your signature. Is it even illegal to alter the hour meter on a tractor?

The New Holland Money Pit is what it is because somewhere in its history the hour meter was turned back.  New tires were installed and it was made to look like a 5 yr old tractor with about 200 hrs per year.

If I remember correctly, the Weibull Curve predicted the lifespan of a manufactured assembly such as a tractor.  It appears to be a gift from the mathematicians.
