Case IH starts shipment of Tier 4a-compliant tractors

New Magnum tractors equipped with SCR technology to reduce emissions

This month Case IH shipped out the first in a lineup of new high-horsepower tractors that meet the U.S. Environmental Protection Agency’s Tier 4a emissions regulations, which take effect January 1. Models shipped include the new Magnum 180, 190, 210, and 225. The company has presold more than 750 Magnum tractors, which range in price from about $175,000 to $250,000. Orders for big diesel tractors have tripled from a year ago, Case says.

This clean air standard applies to all diesel-powered farm vehicles rated 174 hp and above and calls for a 90% reduction of two pollutants:  nitrogen oxides and particulate matter or “soot.”  

To meet these levels Case IH is employing Selective Catalytic Reduction (SCR) technology, which treats emissions after they leave the engine with a stable, non-toxic mixture of urea and water called Diesel Exhaust Fluid (DEF). The DEF tank is filled during refueling and is priced about the same as diesel fuel and used at a rate of 3 to 5 percent of diesel fuel.

Case IH claims the operating cost of its new SCR tractors is 10 percent lower than previous Case IH models as a result of better fuel economy and fewer required oil changes.

Paul Fortkamp of Fort Recovery, OH, was the first customer to take possession of a Case IH tractor equipped with SCR. Fortcamp said he bought the tractor, a 182-hp Magnum 180, because of its fuel efficiency and size, which, he says, “is narrow enough for my rows but big enough for a grain cart.”

Case IH says larger Magnum models and a new generation of Steiger 4WD tractors will be rolled out next to meet the January deadline.
