The State of California has a program called the Carl Moyer program, to which it annually commits $150 million. If a farmer has an older tractor with a tier 0, 1, or 2 engine in it, and the engine needs to be rebuilt or replaced, the State of California will make up the difference between the cost of the rebuild and the tier 3 engine. It commits $150 million to that program.
We fear what might happen when we move to a tier 4 engine. The concept of the tier 4 engine is that the air coming out of the engine is cleaner than the air going into it. There are frame adjustments that will have to be made. We're not even sure if we'll be able to get a tier 4 engine on an older tractor. We have a lot of customers who have made investments in farm equipment over the years, and many dealers have their used inventory. Who's going to absorb the cost? If a farmer's 10-year-old tractor is no longer compliant with environmental standards, who's going to absorb that cost?
