New integrated ROPS cab
A newly designed cab is integrated with ROPS according to
the latest computer analysis. High rigidity and superb sealing
performance sharply reduce noise and vibration for the
operator and prevent dust from entering the cab. Relaxed
operation in comfortable environment. In addition, side
visibility is increased because external ROPS structure and
posts are not required. Outstanding visibility has been
achieved.
Large multi-lingual LCD color monitor
A large user-friendly color monitor enables safe, accurate
and smooth work. Excellent screen visibility is achieved by
use of TFT liquid crystal display that can easily be read at
various angles and lighting conditions. Simple and easy to
operate switches. Plus function keys facilitate multi-function
operations.
Display data in 10 languages to globally support operators
around the world.

Comfortable ride with cab damper mounting
The D65's cab mount uses a cab damper which provides
excellent shock and vibration absorption capacity. The long
stroke cab damper mounts soften shocks and vibration
while traveling over adverse conditions, which conventional
rubber mounting systems are unable to absorb. The cab
damper spring isolates the cab from the machine body,
suppressing vibration and providing a quiet, comfortable
operating environment.

Power angle power tilt dozer (Optional)
A power angle and power tilt dozer blade with highly
durable box-structure frame is optionally available. This
dozer is available for the EX, WX and PX machines. The
hydraulic blade tilt and angling function expands versatility
and productivity in a variety of applications. The manually
adjustable blade pitch further expands the versatility and
productivity.

Preventative maintenance
Preventative maintenance is the only way to ensure long service life from your equipment. That's why Komatsu designed the
D65 with conveniently located maintenance points to make necessary inspections and maintenance quick and easy.
Multi-monitor with troubleshooting function to
prevent critical machine troubles
Various meters, gauges and warning functions are centrally
arranged on the multi-monitor. The monitor simplifies start-
up inspection and promptly warns the operator with a lamp
and buzzer if any abnormalities should occur. In addition,
countermeasures are
indicated in 4 levels to
ensure safety and prevent
the machine from major
problems. Replacement times
for oil and filters are also
indicated.
Low maintenance costs
Parallel Link Undercarriage System (PLUS)
(Optional)
Komatsu's innovative Parallel Link Undercarriage System
features a rotary bushing that demonstrates high durability
in any working conditions. Allowing the bushing to rotate
virtually eliminates bushing wear, resulting in doubled
service life of the undercarriage
Rotating Bushing
when compared with the
conventional undercarriage. In
addition, wear limits of the link and
carrier roller are increased to
balance with the extended service
life of the bushing.
Self-adjusting idler support
Self-adjusting idler support applies a constant spring force to
the wear plate of the idler guide to eliminate the play of the
idler. This results in reduced noise and vibration as well as
extends the service life of the wear plate.
Reliable simple hull frame
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.

Easy radiator cleaning with hydraulic drive fan
The radiator can be cleaned by utilization of the reversible,
hydraulically driven cooling fan. The fan can be reversed
from inside the cab by simply activating a switch.
Oil pressure check ports
Pressure check ports for power train components are
centralized to promote quick and simple diagnosis.
Gull-wing engine side covers
The engine side covers are gull-wing
type with a gas spring, and the opening
angle of the cover is further increased to
facilitate engine maintenance and filter
replacement.
Sealed DT connectors
Main harnesses and controller connectors are equipped with
sealed DT connectors providing high reliability, as well as
water and dust resistance.
Flat face O-ring seals
Flat face O-ring seals are used to securely seal all hydraulic
hose connections preventing leakage.
Enclosed hydraulic piping
Hydraulic piping for the blade tilt cylinder is completely
housed in the push arm, protecting it from damage.
Modular power train design
Power train components are Engine
sealed in a modular design that
allows the components to be
removed and installed without
oil spillage, making servicing Pivot shaft
