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.

Forestry_log loader_literature link_cab2.jpg

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_log loader_literature link_guarding.psd

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_log loader_literature link_cooling system1.png

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.

HM400_Literature link_KOMTRAX_Hi-Res_Cover FIN 1_v2.psd

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.
