Operator Station
Superior comfort keeps you productive, all day long.
The operator station is designed to keep operators comfortable,
relaxed and productive throughout the long work shift. The D4K
features:
• Standard air conditioning with cab option.
• Spacious cab with generous leg room.
• Fully adjustable air suspension seat with a heated seat option
for cold climates.
• Wide door openings for getting in and out of the cab easily.
• Clear view to the blade corners and bottom cutting edge,
especially important in fine grading, working against
foundations and curbing.
• Operator sound level has been lowered inside the cab 4 dB(A)
to an industry leading 80 dB(A) –ANSI/SAE J1166 OCT 98.
This provides a quiet, comfortable working environment
reducing operator fatigue and increasing their productivity.
Seat-Mounted Joystick Controls
For optimum comfort and precise control, the D4K
features ergonomically designed seat-mounted controls.
Seat-mounted controls isolate vibrations from the operator,
and provide independent seat and controls adjustment.
Individual wrist pads and armrests can be adjusted
independently for optimum comfort.
Monitoring Package
Easy to read display provides vital system information.
Buttons below the display allow the operator to select
parameters for forward/reverse speed, blade response,
steering response and decel pedal operation modes.
Dozer Blade Control
Ergonomic joystick is easy to use and reduces operator fatigue.
The intuitive control makes operating the tractor easy for both
new and experienced operators. The new handle shape conforms
to your hand for precise blade raise and tilt control with less
operator fatigue. A thumb roller controls the blade angle and
requires less effort than other competitive machines. A blade
shake button on top of the handle provides momentary quick tilt
movement to easily remove material from the blade.
Combined Decel/Brake Pedal
Decel pedal serves combined function as engine speed control
and brake. Depressing pedal through bottom of travel detent
applies brake. Pedal mode can also be changed to control
transmission speed with selection buttons on the display panel.

Hydrostatic Transmission Control
Seat-mounted controls improve productivity.
Speed and Direction Control
Speed, direction and steering are all controlled with a single, easy
to use joystick for less effort and lower fatigue so you can get
more done. The joystick controls direction and has three simple
detented positions for travel – forward, reverse and neutral.
With the machine in motion, simply move the joystick in the
direction you wish to move the machine. The more the joystick
is moved to the right or left, the tighter the turn. Regardless of
ground conditions, steering is consistent and predictable.
Infinitely Variable Speed Control
The speed control thumb wheel mounted on the joystick is used
to infinitely increase and decrease speed, letting the operator
select the optimum speed for ground and job conditions. It also
eliminates power interruption when changing speeds. A speed
recall button on the joystick is used to select pre-determined
speed settings.
Maneuverability
The power turn feature lets you handle large loads around
corners or through hard spots. Power turn capability improves
mobility in soft underfoot conditions and is very effective on
side slopes. Counter-rotation provides easy, quick maneuvering
in tight areas or congested job sites.
Engine
ACERT™ technology reduces
emissions, increases performance.
The Cat® C4.4 is a 4.4 L (269 in3) displacement, four cylinder,
inline configured engine equipped with a Caterpillar common
rail fuel system. It uses ACERT™ Technology, a series of
Caterpillar engineered innovations that provide advanced
electronic control, precision fuel delivery and refined air
management, resulting in outstanding performance and lower
emissions. It meets the U.S. EPA Tier 3, EU Stage IIIA
and Japan MOC Step 3 emissions standards.
The C4.4 delivers increased horsepower, outstanding
durability, reliability and improved response to change in
loads, delivering power when you need it. The engine is
more compact, allowing the cab to sit more forward – this
improves machine balance and provides greater operator
comfort. The engine and transmission control systems are
integrated to optimize performance and fuel efficiency.

Undercarriage
Lower owning and operating costs.
Undercarriage is a significant portion of a tractor’s owning and
operating costs. Caterpillar offers two different undercarriage
choices for lowest owning and operating costs for your
application needs. A sealed and lubricated track (SALT)
undercarriage is standard; SystemOne™ undercarriage is
available as an option. Full length guarding on top of the track
roller frame prevents abrasive material from falling down on
moving parts.
Machine balance is the key to good grading performance.
Greater track length and a stable platform lead to optimum
balance, allowing you to complete jobs easier and quicker with
the D4K than with competitive machines.
SystemOne Undercarriage
With the revolutionary SystemOne undercarriage option,
undercarriage maintenance time and costs are greatly
reduced, lowering your costs and helping your bottom line.
This innovative system uses a rotating bushing design which
increases bushing life and eliminates the need for bushing turns.
The rotating bushing combined with long wear life sprockets
and center tread idler, increases the life and dependability
of the entire system. Ideal for virtually any application or
underfoot condition, the SystemOne undercarriage also features
significantly less vibration for a better, more comfortable ride.
Sealed and Lubricated Track (SALT) Undercarriage
The standard sealed and lubricated track (SALT) undercarriage
is built for long life in rugged conditions. Segmented sprockets
are easy to replace and less expensive than replacing the complete
sprocket hub.
Choice of Track Frame Configurations
Track frames are available in extra long (XL) or low ground
pressure (LGP) configurations. XL undercarriage provides
increased ground contact area and flotation, superior balance
and excellent finish grading. In addition, the LGP version also
features a wider track shoe, increasing ground contact area
for optimum flotation and stability on sloping and finish
grading jobs.

AccuGrade™ Systems
Grade with increased accuracy.
Caterpillar is revolutionizing the way to move material with new
technology solutions for earthmoving machines – solutions that
provide greater accuracy, higher productivity, lower operating
costs and greater profits. The AccuGrade System is designed and
integrated into the machine and hydraulic systems to create an
automated blade control system that allows operators to grade
with increased accuracy. The system uses machine-mounted
sensors to calculate precise blade slope and elevation information.
AccuGrade Laser
AccuGrade Laser uses a laser transmitter and receiver for precise
grade control. A laser transmitter on the worksite creates a constant
grade reference over the work area. A digital laser receiver mounted
on the machine captures the laser signal. The system calculates
the blade adjustments necessary to achieve grade, makes automatic
elevation adjustments typically performed by the operator and
provides automatic blade control. The operator simply steers the
machine. Automated blade control lets you achieve grade faster
and in fewer passes, reducing the need for traditional survey
stakes or grade checkers. The system also calculates cut/fill
requirements for manual blade control. Work is completed faster,
more accurately and with less manpower. AccuGrade Laser is
well suited for flat work such as concrete pads and driveways.
AccuGrade GPS
AccuGrade GPS computes the machine positioning information
and compares the position of the blade relative to the design plan.
Information is provided to the operator via an in-cab display
showing blade elevation, necessary cut/fill to achieve grade,
blade position on the design surface and a graphical view of the
design plan with machine location. AccuGrade GPS puts all the
information the operator needs to complete the job in the cab for
a greater level of control. Vertical and horizontal guidance tools
visually guide the operator to the desired grade. Automated
features allow the hydraulic system to automatically control
blade adjustments to move the blade to grade. The operator
simply uses the light bars to guide the machine for consistent,
accurate grades and slopes, increasing productivity with less
fatigue. AccuGrade GPS is best used for cut and contour jobs.
AccuGrade Monitor
Caterpillar is the first to integrate this system and its monitor
into the machine’s dash for easy viewing during operation.
The AccuGrade monitor is conveniently located, allowing the
operator to view system information while keeping a straight
line of sight to the blade corners.

Blade and Attachments
Cat work tools can handle tough
dozing applications.
VPAT Blade
The VPAT blade is specifically designed for finish grading, backfilling ditches, cutting
V ditches, windrowing, fill spreading, medium land clearing and heavy dozing. Built for
rugged strength and durability, this 6-way blade allows for adjustable angle, tilt and
pitch. Visibility to the blade corners and cutting edge is improved. This is especially
critical when working near curbs and foundation structures.
Parallelogram Ripper
The aggressive parallelogram ripper lets you do more productive ripper work. The parallel
linkage design provides better penetration and maneuverability in tight working areas.
Forestry Options
An easier way to work in the woods. The D4K is available with the following features
to aid in forestry applications:
• Forestry blade, featuring additional guarding to protect the tractor from debris and to
provide increased productivity.
• Cat hydrostatic winch, featuring excellent line pull at any speed and infinitely variable
drum speed.
• 360 degree guarding, for added protection of the cab.
• Heavy-duty rear tank guard.
Hydrostatic
Winch
Infinitely variable
speed control.
The Cat hydrostatic winch offers
outstanding control of the load with
infinitely variable modulation of speed
and pull. Mechanical winches force
the operator to choose the gear ratio
of the winch. The Cat hydrostatic
winch eliminates this compromise
by providing the speed of a standard
winch and the pull of a low speed
winch, all in one package.
The result is:
• Excellent line pull at any speed
• Infinitely variable drum speed
• Lower operator effort
• Unmatched load control
Page 8
Serviceability
Easy access and minimal maintenance requirements keep
your machine on the job.
Easy Access
Long service intervals and easy maintenance keep the machine
up and running and lower your owning and operating costs.
A large, hinged door on the left side of the engine compartment
provides easy access to all regular engine maintenance points,
including engine fuel filters and water separator, the engine oil
filter, the engine oil dipstick and filler, the fuel priming pump
and the engine air pre-cleaner and filters. Grouped pressure
taps allow for quick testing and troubleshooting of the hydraulic
system. The hydraulic filters are all located in the left rear
service compartment and are accessible from ground level.
Product Link
The optional Product Link system simplifies equipment fleet
tracking. Using satellite or cellular technology, the system
automatically reports information such as location, machine
hours, active and logged service codes and security alarms.
