Features

Komatsu SAA6D114E-5 Engine

Powerful Komatsu SAA6D114E-5 engine provides a net output of 192 kW 257 hp is EPA Tier 4 interim and EU stage 3B emissions certified. Forestry modifications include insulation with heat shields for the diesel particulate filter and debris screens on engine compartment air flow openings.

Komatsu Forestry Cab

The new 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 certifed cab is specifically designed for forestry applicatiaons 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 PC490 class track components and final drives provide 73,880 lbf drawbar pull for excellent slope climbing performance and maneuverability.  Forestry high and wide carbody with 32" ground clearance has a heavy duty swivel guard, full length bottom roller support rock guards and reinforced idler with large recoil spring.  Wide 10'11" gauge improves over the side lift capacity.

Komatsu Live Heel Boom

Komatsu designed and built 42' reach live heel logging boom has Komatsu built boom, arm, heel and hydraulic cylinders.
