simplified with thumb push buttons.
Gearshift pattern preset function
When the gearshift pattern is set to either <F1-R2>, <F2-
R2> or <F2-R3L> in automatic gearshift mode, the gear is
automatically shifted, reducing round trip repetition work
time and operator's efforts.

Palm command PPC controlled blade/ripper
control joystick
Blade control joystick uses a PPC (Proportional Pressure
F
Control) valve and blade control
joystick ergonomics are 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 an electronic signal,
providing ease of operation, eliminating maintenance of
linkage and joints.
Height adjustable armrest (Optional)
Armrest is height adjustable without any tools, providing the
operator with firm arm support.

New integrated ROPS cab (Optional)
A newly designed cab is integrated with ROPS. High rigidity
and superb sealing performance sharply reduce noise and
vibration for the operator and helps prevent dust from
entering the cab. The result is relaxed operation in a
comfortable environment for the operator. 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, accurate and
smooth work. Improved 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. Industry first 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 D155A-6's cab mount uses a cab damper which
provides excellent shock and vibration absorption capacity
with its long stroke. Cab damper mounts soften shocks and
vibration while traveling over adverse conditions, which
conventional 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.
