Palm command
electronic controlled
travel control joystick

Palm command travel joystick
provides the operator with a
relaxed posture and superb
fine control without operator
fatigue. Transmission gear
shifting is simplified with thumb
push buttons.

Full-adjustable suspension seat and travel control
console

The travel control console has adjustment fore and aft, and
height.
For improved rear visibility during reverse operations, the
operator can adjust seat 15° to the right. (optional)

Palm command
PPC controlled
blade control joystick

Blade control joystick uses the
Proportional Pressure Control
(PPC) valve and joystick is
similar to the travel control
joystick. PPC control combined
with the highly reliable Komatsu hydraulic system enables
superb fine control.

Fuel control dial

Engine revolution is controlled by electric signal, providing
ease of operation, eliminating maintenance of linkage and
joints.

Height adjustable armrest

Armrest height is adjustable without any tools, providing the
operator with firm arm support in an ideal armrest.

Komatsu’s ergonomically designed control system “PCCS” creates an operating environment
with

“complete operator control”.

MONITOR SYSTEM

Power train electronic control system

Smooth and soft operation

D61EX/PX utilizes a newly designed power train electronic control system.The controller registers the amount of operator
control (movements of lever and operation of switches) along with machine condition signals from each sensor, to calculate
accurately the control of the transmission for optimal machine operation.The ease of operation and productivity of the new
D61EX/PX is greatly improved through these new features.

Electronic Controlled Modulation Valve (ECMV) controlled transmission

Controller automatically adjusts each clutch engagement depending on travel conditions
such as gear speed, revolution and shifting pattern. This provides smooth shockless clutch
engagement, improved component reliability, improved component life and operator ride
comfort.

Hydrostatic Steering System—smooth, powerful turning

The Hydrostatic Steering System (HSS) is powered by an independent hydraulic pump with
engine power transmitted to both tracks without power interruption on the inside track. When the
machine turns, the outside track moves faster and the inside slower, for smooth, powerful
turns. Counter-rotation is available for minimum turning radius providing excellent
maneuverability. Shock-free steering reduces machine vibration and minimizes operator
fatigue.

Preset travel speed function

Preset travel speed selection function is provided as standard equipment.The preset switch enables the operator to select a
combination of forward/reverse gear shifts, from 5 patterns; F1-R1, F1-R2, F2-R1, F2-R2 and F2-R3, by using UP/DOWN
shift switch, and once the shift pattern is selected, only forward / reverse direction control selection is required. Once F2-R2
pattern is selected, for example, 2nd gear is automatically selected when travel control joystick is moved into
forward/reverse. This function reduces gear shifting frequency during machine operation, and is especially helpful, when
used in combination with auto-downshift function.

Auto-downshift function

Controller monitors engine speed, travel gear and travel speed.
When load is applied and machine travel speed is reduced, the
controller automatically downshifts to optimize gear speed to
provide high fuel efficiency. This function provides comfortable
operation and high productivity without manual downshifting. (This
function can be deactivated with cancel switch.)

Actuated on heavy
load or steep slope

● Tu r ning while dozing— the machine turns by driving the
left and right tracks under power at different speeds
allowing the machine to travel at the same speed as in
straight dozing.

● Side cutting— when side-loading the blade, straight travel
can be maintained utilizing HSS.

● On downhill slopes— the
machine doesn’t require
counter-steering. The joystick
provides the same steering response
on downhill slopes as on flat ground.

● Grading— can be done efficiently without damaging the
ground, because the inside track is not locked during
turning.

Engine

The Komatsu SAA6D107E-1 engine delivers 125 kW 168 HP
at 1850 rpm. The fuel-efficient Komatsu engine, together with
the heavy machine weight, make the D61EX/PX superior
crawler dozers in both ripping and dozing operations.
The engine is EPA Tier 3 and EU Stage 3A emission
regulations certified, and features direct fuel injection,
turbocharger, air-to-air and aftercooler to maximize fuel
efficiency.
To minimize noise and vibration, the engine is mounted to the
main frame with rubber cushions.

Hydraulic drive radiator cooling fan

Fan rotation is automatically controlled depending on coolant
and hydraulic oil temperature, saving fuel consumption and
providing great productivity with a quiet operating environment.

Undercarriage

Low drive and long track undercarriage

Komatsu’s design is extraordinarily tough and offers
excellent grading ability and stability.
The track seal life is increased by using large-size bulldozer
type seals.

Work equipment

5.0 yd3(PAT dozer for D61PX), 4.3 m35.6 yd3(Semi-U dozer
for D61EX) yield outstanding production. High-tensile-strength
steel has been incorporated into the front and sides of the
blade for increased durability.

Photo may include optional equipment.

Operator comfort is essential for productive work.The
D61EX/PX provides a quiet, comfortable environment where
the operator can concentrate on the work at hand.

Hexagonal pressurized cab

● The cab’s new hexagonal design and large tinted glass
windows provide excellent front, side, and rear visibility.

● Air filters and a higher internal air pressure combine
to prevent dust from entering the cab.

Comfortable ride with new cab damper mounting

D61EX/PX’s cab mount uses a new cab damper which
provides excellent shock and vibration absorbtion capacity
with its long stroke. Cab damper mounts soften shocks and
vibration while traveling over adverse conditions, which
conventional mounting system are unable to absorb. The cab
damper spring isolates the cab from machine chassis,
suppressing vibration and providing a quiet, comfortable
operating environment.

New suspension seat (optional)

A newly designed suspension seat is available. Fore and aft
sliding rails and suspension spring have been newly designed
to increase strength and rigidity. The new seat provides
excellent support, improving riding comfort. Fore and aft seat
travel is designed for
almost all operator
sizes. An optional air
suspension seat for
increased riding comfort
is also available. It has
an automatic operator
weight adjustment
system and an air
lumbar support to
improve operator
comfort.

Centralized service station

To assure convenient maintenance, the transmission and
HSS oil filters, power train oil level gauge and hydraulic tank
are arranged on the right side of the machine.

Monitor with self-diagnostic function

With the starting switch turned ON, the monitor displays
check-before-starting and caution items appear on the
lower right part of the panel. If the monitor detects
abnormalities, corresponding warning lamp blinks and
warning buzzer sounds. The monitor displays engine rpm
and forward/reverse gear speed on the upper part of the
monitor during operation. If abnormalities occur during
operation, user code appears on display. When a critical
user code is displayed, the caution lamp blinks and a
warning buzzer sounds to prevent the development of
serious problems.

Easy/cleaning with hydraulic driven radiator
cooling fan

The radiator core and the core on the front side of the oil
cooler can be easily cleaned by running the hydraulic engine
fan in reverse. Accordingly, the cleaning intervals of those
cores can be increased.

Modular power train design

Power train components are sealed in a modular design that
allows the components to be dismounted and mounted
without oil spillage.

Reliable simple structure

Simple hull structure main frame design increases durability
and reduces stress concentration at critical areas. The track
frame has a large cross section and utilizes pivot shaft
mounting for greater reliability.

Maintenance-free disc brakes

Wet disc brakes require less maintenance.

Gull-wing engine side covers

The opening area is further
enlarged when gull-wing
engine side covers are
opened, facilitating engine
maintenance and filter
replacement.

Preventative maintenance

Preventative maintenance is the only way to ensure long service life from your equipment.That’s why Komatsu designed the
D61EX/PX with conveniently located maintenance points to make necessary inspections and maintenance quick and easy.
