2025 Komatsu Forestry Machines 855-3 8WD
Nimble and powerfulEquip your operators to drive productivity day after day in this 14-metric-ton class forwarder that features power, nimbleness and smart features. Hydraulic retarder overspeed protection ensures the driveline won't run too fast, and the flat FlexGate headboard increases load space.
Features may include:
Efficient loading- Match the machine to the job with a variety of load capacities — 12, 14, 16 or 20 metric tons — and several frame-length options. Designed for smooth and precise operation. Rugged cranes have a long reach and excellent lifting and slewing torque.
- Maneuver with confidence in the most rugged forests, even when fully loaded. Chassis and suspensions are designed for performance under demanding conditions. Komatsu Comfort Bogie axles with a high portal offset and V-shaped frames provide some of the highest ground clearance in the industry.
- Maximize performance with high power and torque while driving efficiency with a fuel-efficient engine. A sophisticated control system automatically adapts to changes in engine load.
- Get exceptional tractive force thanks to an intelligent hydrostatic transmission system that considers machine load, terrain conditions, power and torque output. Hydraulic retarder overspeed protection on the 875-1 and 895-2 models ensures the driveline won't run too fast.
- Give operators the benefit of machine controls they can fine-tune for sensitivity and speed or smoothness and accuracy – whatever the job demands. Our state-of-the-art MaxiXplorer/MaxiXT system monitors and controls everything from engine and crane to the transmission and service ladders.
