In preparation to meet the 2014 Tier IV emission specs.
2014 models will have to be equipped with cat converters particulate filters and urea injection.
Purchase your new equipment before the end of 2013.
That emission crap messed up the diesel pickup trucks, now the tractors.
Good advice, get your tractor before 2014, I wonder how much in price it will add? 10K 12K
Tier 4 Emission Standards
The Tier 4 emission standards—to be phased-in from 2008-2015— introduce substantial reductions of NOx (for engines above 56 kW) and PM (above 19 kW), as well as more stringent HC limits. CO emission limits remain unchanged from the Tier 2-3 stage.
Engines up to 560 kW. Tier 4 emission standards for engines up to 560 kW are listed in Table 3.

a - hand-startable, air-cooled, DI engines may be certified to Tier 2 standards through 2009 and to an optional PM standard of 0.6 g/kWh starting in 2010
b - 0.4 g/kWh (Tier 2) if manufacturer complies with the 0.03 g/kWh standard from 2012
c - PM/CO: full compliance from 2012; NOx/HC: Option 1 (if banked Tier 2 credits used)—50% engines must comply in 2012-2013; Option 2 (if no Tier 2 credits claimed)—25% engines must comply in 2012-2014, with full compliance from 2014.12.31
d - PM/CO: full compliance from 2011; NOx/HC: 50% engines must comply in 2011-2013
