SIGMADOZER – The next generation blade

Based on a completely new digging theory, SIGMADOZER
dramatically improves dozing performance and increases
productivity. A new frontal design concept adopted for
digging and rolling up at the center of the blade increases
soil holding capacity while simultaneously reducing sideway
spillage. It also reduces digging resistance producing a

smoother flow of earth, enabling the dozing of larger
quantities of soil with less power.

Outstanding productivity

New fuel efficient bulldozer

The new D65 has achieved both high levels of
productivity and fuel economy through the usage of
SIGMADOZER and automatic transmission with
lockup torque converter. SIGMADOZER developed
based on completely new digging theory dramatically
increases production. New transmission with high
power transmission efficiency greatly reduces fuel
consumption. This bulldozer significantly improves
fuel efficiency compared with our conventional model.

Lockup mechanism of the
torque converter is
automatically actuated to
transfer engine power directly
to the transmission in
travelling and usual dozing
speed ranges. Locking up the
torque converter eliminates
loss of power by 10%.
Because the electronically
controlled engine is extremely
efficient, a decrease in fuel
consumption is realized while
also maintaining machine
power.

Automatic transmission with lockup torque
converter

A sharp reduction in fuel consumption and greater power
train efficiency is achieved by the new automatic gearshift
transmission and lockup torque converter. The automatic
transmission selects the optimal gear range depending on
the working conditions and load placed on the machine.
This means the machine is always operating at maximum
efficiency.

Fuel consumption decreased by

10%

(compared with our conventional model)

Outstanding fuel economy

Automatic/manual gearshift selectable mode

Automatic or manual gearshift modes can be selected with ease to suit the work at hand by simply pressing the switch on
the multi-monitor (selection at neutral).

● Automatic gearshift mode

Select for all general dozing. When a load is applied, the transmission automatically shifts down, and when the load is off,
it automatically shifts up to a set maximum gear speed. This mode economizes both fuel and production further where the
torque converter lockup mechanism is actuated according to load, providing a one to one drive.

● Manual gearshift mode

Select for dozing and ripping rough ground. When loaded, the transmission automatically shifts down, but does not shift up
when the load is off.

Selectable working mode

Working mode P is the mode aiming for powerful operation and maximum production and mode E for general dozing
applications with adequate speed and power while saving energy. For CO

2 reduction and energy saving, the monitor panel

allows for switching the working mode with ease, depending on the work at hand.

● P mode (Power mode)

With P mode, the engine outputs its full power, allowing the machine to perform the work requiring large production,
heavy-load work, and uphill work.

● E mode (Economy mode)

With E mode, the engine outputs enough power for the work without delivering unnecessary power. This mode allows for
energy saving operation and is suitable for the work on a ground where the machine may cause shoe slip and the work
not requiring large power such as downhill dozing, leveling and light-load work.

controlled. The fan rotation speed depends on engine
coolant and hydraulic oil temperatures, the higher the
temperature the higher the fan speed. This system increases
fuel efficiency, reduces the operating noise levels and
requires less horsepower than belt driven fan.

Engine

Komatsu develops and produces all major components,
such as engines, electronics and hydraulic components in
house.
Since all components can be matched, efficiencies are
increased achieving high levels of productivity and ecology.
With this "Komatsu Technology", and adding customer
feedback, Komatsu is achieving great advancements in
technology.
The result is a new generation of high performance and
environment friendly machines.

Palm command hydraulic controlled blade/ripper
joystick

Hydraulically-controlled palm command joystick is equipped
for blade/ ripper control. Combined with the highly reliable
Komatsu hydraulic system, superb control is the result.

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

Human-Machine Interface PCCS (Palm Command Control System)

Gearshift pattern preset function

When the gearshift pattern is set to either <F1-R2>,
<F2-R1>, <F2-R2>, <F2-R3L> or <F3L-R3L> in the
automatic gearshift mode, the gear automatically shifts to
the preset gear when the travel control joystick is set to
Forward or Reverse position, reducing round trip repetition
work time and operator’s efforts. Gearshift pattern
<F2-R3L> and <F3L-R3L> are newly added for high speed
leveling operation.
