The Cat® D3K Track-Type Tractor delivers superior
performance and comfort while reducing your operating
costs. The large spacious cab provides a comfortable
work area. Intuitive seat-mounted controls are easy to
use for greater job accuracy and efficiency. The innovative
SystemOne undercarriage reduces maintenance time
and costs – significantly impacting your bottom line.
The AccuGrade Laser and GPS Systems help you get
to grade faster, with fewer passes and less manpower.
From the first cut to finish grade, the D3K sets the standard.

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 D3K
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 D3K
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 D3K 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. As an additional choice, the LGP undercarriage on the
D3K is available with 762 mm (30 in) shoes.
