The new emissions standerds for diesels, known as Tier II, do not come into effect on compact tractors for another year (I think). Tier II is being phased in by horsepower and higher power construction and farm equipment is being hit first.
Manufacturers are scrambling to find ways to make cleaner burning engines. Mostly what you will see for Tier II is electronically controlled engines. Similar to what has happened in cars, electronic engines presisely monitor engine timing and fuel injection. Of course Tier II engines will burn more fuel and produce less power. As some of you may remember last year (or was it 2 years ago) Cummins, Cat, and Detroit Diesel all got in trouble with the EPA because they were changing fuel maps in thier truck engines. The engine would burn less fuel and produce more power but it was no longer emissions compliant. For those of you with a Ford truck with the 7.3l Powerstroke, you can acheive a similar result by buying an aftermarket chip for the engine computer. The chip will give you from 30 to 100 additional horsepower and 6 more miles per gallon (reported to me by somebody who "chipped" his truck). Of course your engine will no longer be emissions compliant.
I am not sure when Tier II kicks in for compacts but when it is getting close look for updated tractors with emissions engines. The manufacturer websites and product lit will most likely be touting Tier II compliance when this occurs. Several construction machines are already boasting Tier II compliance.
