New Komatsu Traction Control System (KTCS) monitors for wheel spin and automatically applies independent brake assemblies for optimum traction in all ground conditions to improve productivity
Tier 4 Final Komatsu engine with increased horsepower provides exceptional performance while reducing fuel consumption up to seven percent
The McPherson strut type suspension with a special A-arm between each wheel and the main frame provides a small 28 feet 7 inch turning radius
Keeping track of production is easier with a standard integrated Payload Meter (PLM). Loaded material weight is displayed on the LCD monitor for the truck operator and external display lamps light up when the truck has reached capacity, minimizing underloaded or overloaded haul cycles. Production data can be monitored through KOMTRAX or downloaded

The all new cab is mounted on top of viscous dampers to reduce mechanical vibration and noise transmitted from the machine to the operator environment
Rear hydropneumatic rear suspension provides a smooth ride over rough terrain to maximize production and operator comfort
Large capacity, continuously cooled multiple disc brakes also function as a highly responsive retarder providing the operator confidence at high speed
Automatic retard speed control (ARSC) allows the operator to simply set downhill travel speed for added operator confidence with 1,075 HP of retarding capacity

All major components including the engine, torque converter, transmission, hydraulic system, and electrical system are designed and manufactured by Komatsu
Components are manufactured to strict Komatsu quality standards for durability and reliability
Komatsu Advanced Transmission with Optimum Modulation Control System (K-ATOMiCS) with skip shift function provides long life and optimized performance
A high-rigidity frame is used with cast steel components used in critical areas of the main frame where loads and shocks are most concentrated
The powerful and fuel efficient Komatsu SAA6D170-7 engine provides five percent more horsepower and only requires Komatsu Diesel Particulate Filters for aftertreatment

The new ergonomic cab ROPS / FOPS cab provides the operator with a large, quiet and pressurized work environment while providing excellent visibility during operation
The new high capacity operator’s seat is equipped with air suspension, 3-point seat belt, and is heated and ventilated for added comfort
A forward-facing training seat with a 3” lap belt is located on the right side of the cab and can be folded
The front dash panel provides excellent visibility to a 7” monitor and a rearview monitoring system
New stairways and walkways are made with dimpled slip-resistant plates for better traction

New ground level access to the batteries helps facilitate daily checks and battery replacement
The filters are conveniently grouped for easy service
A new hydraulically driven reversible fan can be set to clean mode in the monitor
Every Komatsu Tier 4 Final construction machine comes standard with Komatsu CARE complimentary factory scheduled maintenance for 2,000 hours or the first 3 years whichever comes first, and one complimentary KDPF exchange (which includes both KDPF assemblies) in the first five years
KOMTRAX is included at no additional charge and allows easy management of your equipment asset
