Features

Roof Mounted AC Condenser

Moves condenser to a lower debris area for improved serviceability.

Belly Guard Seal Kit and Powered Engine Belly Pan Winch

Seal kit helps reduce debris from entering the engine compartment. Powered belly pan simplifies cleaning.

Quick Opening Two (2) Piece Radiator Guard Doors and Flexxaire Auto Reversing Fan

Doors allow easy access to the standard wide core radiator for cleanings. Computer controlled forward and reverse fan intervals allow the operator to concentrate on productivity while keeping the radiator and oil cooler clean.

Engine Exhaust Thermal Shield

Covers exhaust manifold, KDPF, and hot side of the turbo charger in order to reduce ignition temperature and thus reduce potential for fire.

Counterweight, HD w/ Rear Striker Bars and Hitch

Optimizes machine balance for landfill applications (1046 kg 2,306 lb)(Required unless winch or ripper is ordered).

Front Striker Bars, Frame Mounted (not available on PX or PAT blade) and Track Shoes with Holes

Striker bars help prevent debris from riding up on tracks and damaging chassis. Track shoe holes minimize packing and extend component life.

Automatic Transmission with Lockup Torque Converter

A significant reduction in fuel consumption and greater power train efficiency are achieved by the new automatic 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.

The 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 results in 10% improved drive train efficiency. Because the electronically controlled Tier 4 Interim engine is extremely efficient, an additional 5% decrease in fuel consumption is realized while also maintaining machine power.

Rear View Monitoring System

On the large LCD color monitor, the operator can view, through one camera, areas directly behind the machine. This camera can be synchronized with reverse operation.

Palm Command Control System (PCCS) Travel Joystick

Palm command travel joystick provides the operator with a relaxed posture and superb fine control. Transmission shifting is simplified with thumb push buttons.

Palm Command Proportional Pressure Control (PPC) Blade Control Joystick

Blade control joystick uses the PPC valve and joystick, similar to the travel control joystick. PPC control combined with the highly reliable Komatsu hydraulic system enables superb fine control. A switch is now used to angle the PAT blade.

Automatic shift 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 when the torque converter lockup mechanism is actuated according to load, providing a one-to-one drive.

Manual shift 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.

Newly Integrated ROPS Cab

A newly designed cab; wider, deeper and taller, is integrated with the ROPS. High rigidity and superb sealing performance greatly reduce noise and vibration for the operator and minimize dust entering the cab. The standard air-ride seat positions the operator 3" higher and 4" closer to the blade. The taller and narrower battery box and tanks plus larger glass area also improve visibility of the blade, sides, and rear of the machine. Cab meets OSHA/MSHA ROPS and FOPS Level 2 standards.

Large Multi-Lingual LCD Color Monitor

A large user-friendly color monitor enables accurate and smooth work. Excellent screen visibility is achieved by the use of a TFT liquid crystal display that can easily be read at various angles and lighting conditions. Simple and easy to operate switches. Function keys facilitate multi-function operations. Data can be displayed in 25 languages for local customization.

Parallel Link Undercarriage System PLUS

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 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 extended service life of the wear plate.

Steering System    
     
Palm Command Control System (PCCS) lever controls for all directional movements. Pushing the PCCS lever forward results in forward machine travel, while pulling it rearward reverses the machine. Simply tilt the PCCS lever to left to make a left turn. Tilt it to the right for a right turn.    
Hydrostatic Steering System (HSS) is powered by steering planetary units and a hydraulic pump and motor. Counter-rotation turns are also available. Wet, multiple-disc, pedal-controlled service brakes are spring-actuated and hydraulically released. Gear shift lock lever also applies parking brake.
