Power train electronic control system
Smooth and soft operation
D85EX/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
D85EX/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 4 patterns; F1-R1, F1-R2, F2-R1 and F2-R2, by using UP/DOWN shift switch,
and once the shift pattern is selected, operator can control the machine concentrating his attention on directional control only.
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.)

●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.

PRODUCTIVITY FEATURES

CRAWLER DOZER
D85EX/PX-15R CRAWLER DOZER
Photo may include optional equipment.
Engine
The Komatsu SAA6D125E-5 engine delivers 197 kW 264 HP
at 1900 rpm. The fuel-efficient Komatsu engine, together
with the heavy machine weight, make the D85EX/PX supe-
rior crawler dozers in both ripping and dozing operations.
The engine features direct fuel injection, turbocharger, and
air-to-air 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. Large-diameter
bushings, increased track link heights, and improved oil-
seals help to increase undercarriage durability.
Improvements
Numerous improvements to increase undercarriage
reliability and durability have been incorporated.
Serviceability has also been improved with the addition of
remote greasing of the equalizer bar center pin.
Operator comfort is essential for productive work.
The D85EX/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
D85EX/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
D85EX/PX uses a new suspension seat. Fore and aft
sliding rails and suspension spring increase strength and
rigidity. The new seat provides excellent support, improving
riding comfort. Fore
and aft seat travel can
be adjusted to
accommodate different
operator sizes.

Capacities of 5.2 m36.8 yd3(Straight tilt dozer for D85EX),
5.9 m37.7 yd3(D85PX), 7.0m39.2 yd3(Semi-U tilt dozer for
D85EX) yield outstanding production. High-tensile-strength
steel has been incorporated into the front and sides of the
blade for increased durability.
Rippers (EX)
●The multi-shank ripper features a long sprocket center-to-
ripper point distance, making ripping operation easy and
effective while maintaining high penetration force.
●The multi-shank ripper is a parallelogram type ideal for
ripping in tough material. The ripping depth is adjustable in
two stages.

EASY MAINTENANCE
D85-15
CRAWLER DOZER
D85EX/PX-15R CRAWLER DOZER
RELIABILITY FEATURES
Centralized service station
To assure convenient maintenance, the transmission and
HSS oil filters, power train oil level gauges and hydraulic
tank are arranged in 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 finds
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 drive radiator 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.
Electric priming pump
Simply pressing the button enables bleeding air from the
fuel circuit at the time of filter replacement, etc.
Enclosed hydraulic piping
Hydraulic piping for the blade tilt cylinder is completely
housed in the push arm, ensuring damage protection from
materials.
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. Side covers
have been changed to a
thick one-piece structure with
a bolt-on catch to improve durability.
Heavy-duty track link
The track link life is greatly improved through increased
bushing diameter and link height in addition to lubricated
track.
Preventative maintenance
Preventative maintenance is the only way to ensure long service life from your equipment. That’s why Komatsu designed the
D85EX/PX with conveniently located maintenance points to make necessary inspections and maintenance quick and easy.
Filtration
Engine
Newly added main fuel filter of 2µm and water separator
protect the engine against dirt and water in the fuel.
The fuel tank is
equipped with a high-
filtration breather with
pressure valve to
prevent dust from
entering.
Hydraulic
A filter is added to the
hydraulic tank cap in
order to prevent dust
from entering the tank
cap and protect
hydraulic components
against dust.
