secure the in-cab display. Plug-in points
inside the cab and on the front of the
machine make it easy to install
electronic components.
AccuGrade GPS Control System.
The AccuGrade Global Positioning
System (GPS) is the best solution when
the construction site involves contours,
rather than single or dual slope planes.
A GPS system compares the blade
position to a three-dimensional
computerized job site plan and signals
the operator or hydraulic system to raise
or lower the blade to achieve the design
requirements.
Computer Aided Earthmoving System
(CAES) (optional). This on-board
electronic site plan directs machine
operators, in real-time, where to cut and
fill. A graphical map of the design plan
and a view of the machine’s horizontal
and vertical position simplify operation
and enhance production. This advanced
information tool combines GPS
technology (centimeter-level) and in-cab
computing capabilities for precise grade
and slope control. It has proven to
provide measurable impact on work

Page 9
Torque Converter. A high efficiency
torque converter with fixed stator
provides high torque multiplication
while shielding the drive train from
sudden torque shocks and vibration.
Additional Feedback. A minor, but
important, by-product of the torque
converter is its tendency to increase
engine lug all the way to converter
stall. This gives the operator additional
feedback concerning tractor speed
and drawbar pull.
Differential Steering System. A planetary
differential turns the machine by speeding
up one track and slowing the other,
while maintaining full power to both.
Differential steering system consists of:
• Three planetary gear sets:
• Two planetary gear sets (steering
and drive) make up the “dual
differential,” which performs the
traditional drive function (forward
or reverse). Unlike competitive
machines, the differential also
performs a steering function with
input from the steering motor.
• A third planetary gear set, the
“equalizing planetary,” resides
inside the transmission case. It is
connected to the dual differential,
which provides a maximum speed
difference between the right and
left final drives during a turn.
• A dedicated variable-displacement
hydraulic pump.
• A bi-directional, fixed-displacement
steering motor.
• Heavy-duty steering drive gears.
Operation. When moving straight
ahead, power flows through the
transmission pinion and bevel gear into
the dual differential, transmitting equal,
uninterrupted power to each final drive.
While turning, power is shifted to
the outboard track speeding it up.
The inboard track slows down to
accommodate a tighter turning radius.
Forward ground speed remains the
same throughout the turn.
Planetary Power Shift Transmission.
Three speeds forward and three speeds
reverse, utilizing large diameter, high
capacity, oil-cooled clutches.
• Modulation system permits fast
speed and direction changes.
• Modular transmission and differential
slide into rear case for servicing
ease, even with ripper installed.
• Oil-to-water cooler for maximum
cooling capacity.
• Forced oil flow lubricates and cools
clutch packs to provide maximum
clutch life.
Drawbar Pull vs. Speed. As loads on
the tractor increase, the D9T offers
unmatched lugging capability and
smooth shifting as the need occurs
to change gears under varying loads.
The 3-speed forward, 3-speed reverse
transmission, backed by differential
steering, offers excellent runout speeds
and accurate steering capability
under load.
Elevated Final Drives. Isolated from
ground and equipment induced impact
loads for extended power train life.
• Crown-shaved drive gears provide
smooth, quiet, low maintenance
operation.
• Splash lubrication and Duo-Cone
®
Seals extend service life.
