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 is EPA/CARB Tier 3 and EU stage 3 emission
regulations certified, and features direct fuel injection,
turbocharger, air-to-air aftercooler, and cooled EGR system
to maximize fuel efficiency.
To minimize noise and vibration, the engine is mounted to
the main frame with rubber cushions.
Hydrostatic driven engine 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.

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 single shank
ripper ideal for ripping in tough material. The ripping depth
is adjustable in two stages.
Operator comfort is essential for safe and 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
cover almost all for all
operator sizes.
