Regulate fuel efficiency for lighter work on flat ground with ‘economy’ and ‘economy light’ modes. For higher production jobs and uphill hauling, use ‘power’ mode to increase engine maximum output and raise the upshift and downshift engine speeds during operation.

Maneuver in and out of tight spaces with a tight turning radius (28’ 7"). The MacPherson strut-type independent front suspension features an A-arm wheel-to-main frame design for wider spacing and easy access to the engine bay.

Handle steep grades with fully hydraulic-controlled wet multiple-disc brakes on the rear axle. These large-capacity, continuously-oil-cooled brakes also function as a responsive retarder, giving operators confidence at higher downhill speeds.

Control downhill descent by setting your desired travel speed with the automatic retard speed control (ARSC), which automatically applies the brake retarder to maintain the desired setting and descend the road with confidence.

Operate at peak efficiency with the Komatsu Advanced Transmission with Optimum Modulation Control System (K-ATOMiCS). Designed to help avoid unnecessary fuel consumption and reduce material spillage by automatically selecting a gear depending on grade, speed and acceleration.

Stay focused while operating in loose or slippery haul road conditions with Komatsu's Traction Control System (KTCS), which monitors the rear wheels for slippage and automatically applies the brakes independently to each wheel for enhanced traction.

Cast-steel components are used in critical areas of the main frame where loads and shocks are most concentrated for increased machine durability.
