Performance, Reliability and Durability


Komatsu 40' Live Heel Forestry Front

Komatsu designed and built 40' reach live heel forestry front has Komatsu built cylinders, arm and boom cylinder guards, and 2 powerful LED working lights for high productivity.

Komatsu 32' Reach Processor Front

Komatsu designed and built 32' reach processor front is built for high productivity plus allows for a transport position like an excavator. Available with a Komatsu 398 processing head or to fit other brands of heads.

Komatsu Forestry Cab

The ROPS/OPS/FOPS/TOPS/FOG/WCB/Oregon OSHA certified Komatsu Forestry cab provides a comfortable and quiet work environment so operators can maximize their productivity. The OPS certified cab is specifically designed for forestry applications and gains strength from a reinforced framework.  The operator platform is mounted on viscous damper mounts to isolate vibrations from cab floor.

Komatsu Forestry Undercarriage

Large PC290 class track components and PC360 class final drives provide 64,520 lbf drawbar pull for excellent slope climbing performance and maneuverability. Forestry high and wide carbody with 28" ground clearance has a heavy duty swivel guard, full length bottom roller support rock guards and reinforced idler with large recoil spring.

High Performance Forestry Cooling System

Robust Bar & Plate 3 mm Wide Fin Single Radiator, Hydraulic Oil Cooler and Charge Air Cooler Cores: Reduces clogging for improved productivity and reliability.

Variable Pitch Reversing Fan

(Standard on Processor; Optional on Road Builder):
Reduces debris build-up and HP consumption. Variable blade pitch control automatically manages airflow direction and volume to deliver only as much airflow as needed. Reverses airflow every 20 minutes to purge debris (plus has a manual overide).
