Preliminary Nebraska Tractor Test Lab results indicate that new Tier 4A Case IH tractors with

Selective Catalytic Reduction (SCR) technology have set new industry records for

fuel-efficient power.

In all, the tests confirmed several advantages for the new Case IH tractors, including:

-

Record-breaking fuel efficiency of up to 12 percent advantage over competitors' Tier 3 performance

- Up to 495 drawbar horsepower - a new record for handling today's larger implements

- Lower operating cost through enhanced fluid efficiency

• The Nebraska Tests measured maximum drawbar horsepower and fuel efficiency for

           Tier 4A Case IH Steiger and Magnum tractors along with Tier 3 compliant tractors in

           their category, including Deere models. 

Unlike Exhaust Gas Recirculation (EGR) systems, SCR technology routes clean and cool air to the engine.

This allows Case IH to fine-tune their engines' combustion process for improved fuel efficiency, lower

engine temperatures, increased reliability and longer maintenance intervals. It also allows producers to

avoid having to deal with issues such as the limiting of engine idling, which some manufacturers with

EGR have recommended to minimize particulate filter regeneration and servicing.

By avoiding EGR, not only do we improve fuel efficiency, but also the engine oil is kept cleaner , which

allows extended oil change intervals and longer engine life. The result is lower operating cost, because

DEF usage is more than offset by enhanced fuel efficiency and fewer oil changes, providing an improved

 total overall fluid efficiency.

SCR puts producers in a position to be ready for final Tier 4B regulations in 2014. Many industry

 observers have acknowledged that SCR will become the future standard for farm tractors.
