Top Features

Powerful and Fuel Efficient Tier 4 Final Engine

The Komatsu 11.04 liter D85-18 Tier 4 Final electronic controlled engine uses a high efficiency combustion chamber and a higher fuel injection pressure to achieve maximum horsepower and engine torque rise. It is precisely tuned to use less fuel than the prior model.

Komatsu Variable Geometry turbocharger (KVGT) with a hydraulic actuator delivers optimum air flow under all speed and load conditions and improves low speed engine response.

The Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR) automatically clean the exhaust gas with a high percent of passive regeneration and is seamless to the operator.

The Auto-Idle Shutdown function can be activated to further reduce fuel costs.


Productivity Advantages

Komatsu's exclusive  SIGMADOZER blade has a unique shape to reduce digging resistance while providing smooth material roll up thereby increasing production by up to 15 % over a similar sized Semi-U blade.

The SIGMADOZER blade power pitch function allows the operator to adjust the blade rearward  for normal dig and carry and forward for more aggressive dig and dump.

The Auto-shift Transmission increases dozing speed while reducing fuel consumption by up to 5% and the hydrostatic steering system maintains power to both tracks during turns.

Manual shift transmission can be selected with a toggle switch for applications such as ripping.

The D85PX-18 with straight tilt blade has wide 36" track shoes and long track-on-ground to provide floatation in soft ground conditions.


Operator Friendly and Comfortable Cab

A pressurized and integrated ROPS cab with large windows and rear view monitor improves visibility 360 degrees around the machine.

A standard air suppression seat along with oil-filled cab damper suspension provides a smooth ride with low noise levels.

A high resolution LCD color monitor with pull-down menus enables quick operational adjustments and has enhanced service diagnostics capability.

An auxiliary input allows operator to connect an MP3 player and hear sound through the cab stereo speakers. 2 standard 12V outlets provide power for mobile devices.


Maintenance Made Easy

Daily Check points are easily accessible.

The high capacity side-by-side wide-core coolers are easy to clean with the hydraulically-driven cooling fan with clean mode. Hinged double radiator doors open wide for convenient access.

Komatsu CARE complementary scheduled maintenance for 3 years / 2000 hours lowers operating costs and provides additional peace of mind.

Up to two complimentary KDPF exchanges and two DEF tank flushes within first 5 years reduce your O&O costs.

KOMTRAX is provided at no charge. Reports are available to view fuel and DEF consumption, working modes and other "actionable information" for fleet managers.
