For 2008, the Case IH Steiger® line introduces five new models
including four-wheel drive and Quadtrac® configurations with
up to 589 peak horsepower and enhanced fuel efficiency.
The Case IH Steiger 535 is one of five new Steiger models being
introduced at farm shows this fall. The 535 is the biggest of the
bunch – with a 15L engine rated at 535 horsepower.
The 2008 Steiger models include a number of Quadtrac and scraper
configurations to meet the diverse needs of large ag producers
and contractors. All carry a special decal commemorating the 50th
anniversary of the groundbreaking design.
New Turbo Compound in Steiger 485 boosts fuel efficiency
The proven 12.9-liter engine previously used in mid-sized Steiger
models is now enhanced with an exclusive new "compound turbocharger" technology
standard in the new Steiger 485. "This is essentially the
same engine that has been used in the Steiger 380 and 430 models,
with one major change: Turbo Compound technology for outstanding
fuel efficiency," says Tom Dean, North American marketing
manager for Magnum tractors.
"Turbo Compound involves two turbo sets working in a series," Dean
explains. "The first turbo performs as a conventional turbocharger
using exhaust gas to compress air into the combustion chamber.
In the Turbo Compound system, instead of routing the exhaust out
the exhaust pipe, it then goes to a second turbine downstream from
the turbocharger. The energy from this second power turbine then
transfers power to the crankshaft through a set of reduction gears
and a hydro coupling. This provides fuel efficiency gains of up
to 3 percent. The result is increased performance, horsepower and
Dean adds that while Turbo Compound technology has been used in
some on-highway applications, "We believe this is the first
time it's been used in an agricultural tractor and will mean outstanding
fuel savings for the customer."
2008 Steiger models
Enhanced center-pull drawbar design
Because Case IH Steiger customers are pulling bigger, heavier
implements than ever, the company made several enhancements to
the center-pull drawbar design, while maintaining key center-pull
benefits such as load distribution and power-to-the-ground. The
hanger bar's size increases from 1.5 to 1.75 inches, improving
bend strength by 37 percent for the heaviest loads.
The hanger bar is now integral to the chassis, improving stress
distribution. It now extends through the side frame, and is welded
on both sides for increased strength. The design uses a 2.5-inch
solid bar design with a heavier, 1-inch-thick support plate, and
is interchangeable between all frame sizes. In addition, the drawbar
side-swing angle has been increased 29 percent, reducing front
frame side loading and improving ride quality. These combined designs
provide a durable drawbar system to handle today's larger implements
and larger requirements of the future.
Industry's first complete factory-installed autoguidance
Previous Steiger tractors came standard as "AccuGuide Ready" --
allowing autoguidance to be added in the field. Now, the 2008 models
take the growing popularity of autoguidance one step further by
offering the complete AFS AccuGuide autoguidance system factory-installed.
"This is an industry-first for Case IH," says Dean, "For
the first time we're shipping tractors with all the autoguidance
components installed right at the factory. Growers are adopting
autoguidance at a very fast pace with smart features and powerful
technologies that deliver all the productivity and profitability
our customers expect."
Steiger AccuSteer™ II system
Exclusively from Case IH, the AccuSteerTM II system is a four-wheel
drive articulated tractor system available on the Steiger 335 model
for row crop applications, where precision steering is critical.
"The AccuSteer II provides intuitive point and steer operation;
allows the front frame to pivot independent of the rear; eliminates
the "tail wag" associated with articulated four-wheel
drive tractors for better steering control within rows; and enables
easy turns at the end of rows," says Dean. "The system
delivers the industry's tightest turning radius for 4WD tractors,
at 12.4 feet."
AccuSteer II was recently awarded the prestigious AE50 award from
the American Society of Agricultural and Biological Engineers.
Design enhancements for 2008 include improved performance and reliability;
system hydraulics and electronics integrated with the base tractor;
all new steering angle sensors and steering wheel encoder; and
a make-up system to overcome drift.
Expanded biodiesel compatibility
In 2008 models, the use of B5 biodiesel is fully approved for
all Steiger tractors. Higher blends also can be used -- B20 in
all models, and B100 in the 385, 435 and 485 - with use of required
Case IH biodiesel maintenance practices.
"Case IH is committed to supporting and promoting the renewable
fuels grown by our customers," Dean says. "This commitment
extends to our most powerful, highest-horsepower Steiger tractors
