Top Features

Machine Performance

Redesigned Komatsu bucket with liner and bolt- on ground engagement tooling (GET) fills more easily and retains material better for up to 7% increased productivity.

Powerful Komatsu SAA6D170E-7 Tier4 Final engine with advanced engine timing optimizes performance and reduces emissions.

Variable traction control and modulated clutch systems provide optimal tractive effort for all ground conditions.

Large Capacity Lock-up Torque Converter provides quick acceleration and automatically engages in 2nd, 3rd, and 4th gear, requiring no action from the operator.

Ultimate Efficiency

Automatic Digging System performs bucket curl and boom lift during digging to reduce operator fatigue and help optimize bucket fill factors.

Komatsu SmartLoader Logic helps reduce fuel consumption without decreasing production.

Fuel Consumption Decreased up to 13% in E mode.

Dual work modes allow the operator to select between Power and Economy modes to optimize the machine efficiency and performance to match the application.

Komatsu Quality

All major hydraulic and power train components (engine, transmission, pumps, cylinders, etc) are designed and manufactured by Komatsu which helps increase efficiency and performance by working together in harmony.

Castings are used in high stress areas such as the bell-crank to increase durability and visibility.

Standard RH full fender with steps and handrail provides improved access to engine compartment for daily checks.

The pillar-less operator's cabin provides the operator with a large, quiet and pressurized work environment while providing excellent visibility during operation.

New high capacity air suspension operator's seat with heat and dampener is now standard.

New 7'' LCD high resolution monitor with key pad allows the operator fast, accurate viewing of operational information.

New rear view monitor system with separate monitor is standard.

Standard Advanced Joystick Steering System (AJSS) helps optimize steering control while reducing operator fatigue.

Maintenance KOMTRAX

Komatsu CARE complimentary factory scheduled engine maintenance for 3 years or 2,000 hrs, and up to 2 complimentary KDPF exchange assemblies within the first 5 years.

Battery disconnect switch is located at ground level and can be locked with a standard padlock.

Reversible cooling fan swings out for ease of cleaning.

Convenient Diesel Exhaust Fluid (DEF) fill access with sight gauge.

Standard onboard diagnostics with KOMTRAX, monitor machine utilization, maintenance reminders, fuel consumption, working modes, KDPF regeneration, DEF level, payload data, and receive e-mail notifications of important events.
