We look at it this way: how quickly are our customers trading in their equipment? In the seventies and early eighties, it was very common for a smaller farm, with smaller-sized equipment, to hang on to a combine for anywhere from 8 to 12 years before the effective life of the machine was pretty done and major overhaul work would have to be done on it. Now we're seeing with the high-end stuff that they're doing more bushels, more acres, and they're doing it in a shorter period of time. We're seeing the five-year range now as the effective life cycle.
That came from data that came from our dealers. That was the basis for our organization going to Washington, D.C., and getting the change from seven to five years.
