Durability and performance in one

When it comes to maximizing your productivity, the HM300-5 delivers maneuverability, comfort and durability in one — even in harsh conditions. Automated powertrain features allow consistent cycle times from all operator experience levels.

Features may include:

• Monitor and adjust to changing conditions. Komatsu Traction Control System (KTCS) is designed to provide excellent machine performance in soft and slippery ground conditions without sacrificing steering performance.

• Powerful acceleration, smooth down shifting and synchronized engine speed. The K-ATOMiCS transmission features a six-speed, fully automatic transmission with an advanced electronic system to reduce shift shock and torque cutoff for exceptional efficiency.

• Increase operator confidence when traveling down hill through large capacity, continuously cooled, wet multiple-disk brakes that also function as a highly responsive retarder with 526 horsepower absorption capacity.

• Discover a smooth ride over the rough terrain with front and rear axle hydro-pneumatic suspensions. The rear axles are mounted on a dynamic equalizer structure and the entire system is designed to help reduce operator fatigue while offering a comfortable ride.

• Improved cab entry in front of the front axle. A curved front dash panel. Thoughtful design enhancements throughout the cab provide the operator excellent visibility and a large, quiet environment to promote productivity and comfort.
