Product Features and benefits:
High Swing Torque and Drawbar Pull: Experience superior performance in demanding applications like shovel logging, truck loading, and road building with high swing torque and maximum drawbar pull.
Rugged Forestry-Specific Undercarriage: Designed with larger class-size components for long-lasting performance. The high and wide design ensures excellent ground clearance in challenging forestry environments.
Powerful, Fuel-Efficient Engine: A robust engine with a net output of 213 HP (159 kW). Komatsu’s proprietary technology ensures exceptional performance with low fuel consumption.
High-Performance Front Work Equipment: Engineered to enhance productivity in log loading, shovel logging, road building, and processing. Komatsu-designed setups deliver efficient and reliable operation.
Modern, Comfortable, Quiet Forestry Cab: The spacious forestry-specific cab offers a comfortable, climate-controlled, and quiet work environment for extended productivity. The ergonomically designed operator’s seat is cushioned with air suspension and heated for cool conditions.
Robust Forestry Guarding: Maximize uptime in challenging forestry environments with robust guarding, including thicker service undercover guards, rear compartment doors, right corner guard with tree deflector, intake and exhaust screens, and more.
Forestry Cooling System: Specially designed cooling system ensures proper cooling in high-debris environments. The robust wide-fin radiator is protected by fine screens, and a variable pitch reversing fan (standard on Processor; optional on Road Builder) enhances airflow.
Komtrax Monitoring System: Continuously monitors and records machine health and operational data, aiding in lowering owning and operating costs. It enables proactive maintenance planning by notifying you when maintenance is due.
Komatsu Care: This complimentary maintenance program covers most regular service, inspections, filter and fluid replacement, and labor for the first three years or 2,000 hours (whichever occurs first), ensuring your machine performs at its best.
