Features and benefits

High swing torque and drawbar pull

High swing torque and maximum drawbar pull deliver superior performance you’ll appreciate in tough shovel logging, truck loading and road building applications.

Rugged forestry-specific undercarriage

Undercarriage designed with larger class-size components to perform year after year. High and wide design for excellent ground clearance in the tough forestry environments you face.

Powerful, fuel-efficient engine

Powerful engine with a net output of 213 HP (159 kW). Proprietary Komatsu technology delivers exceptional performance with low fuel consumption.

High performance front work equipment

Engineered to assist you in being more productive. Komatsu-designed setups for log loading, shovel logging, road building and processing.

Modern, comfortable, quiet forestry cab

Spacious forestry-specific cab provides a comfortable, climate controlled and quiet work environment to support daylong productivity. Ergonomically designed operator’s seat is cushioned with an air suspension and heated for cool conditions.

Forestry guarding

Robust guarding designed to help maximize uptime in your difficult forestry work environment. Thicker service undercover guards, thicker rear compartment doors, right corner guard with tree deflector, intake and exhaust screens, and much more.

Forestry cooling system

Special cooling system helps ensure proper cooling in your high-debris environments. Robust wide-fin radiator design protected by fine screens. Variable pitch reversing fan (standard on Processor; optional on Road Builder) for improved airflow.

Komtrax monitoring system

Continuously monitors and records machine health and operational data – such as fuel consumption and utilization – to aid in lowering owning and operating costs. Enables planning for future maintenance needs by letting you know when maintenance is due.

Komatsu Care

Our complimentary maintenance program helps keep your machine producing at its best. For the first three years or 2,000 hours (whichever occurs first) we take care of most regular service, inspection, filter and fluid replacement, and labor.
