Efficiency

        

  • Engine, hydraulics, and work tool integration are optimized to minimize power losses and increase overall machine efficiency
  •     

  • Steady state high idle speed and U.S. EPA Tier 4 Final technology reduce fuel consumption
  •     

  • Larger hydraulic pumps allow engine to operate at lower rpms with increased performance to maximize efficiency
  •     

  • Component layout and back-to-back main hydraulic control valve reduce oil flow restrictions and aid in greater fuel economy
  •     

  • Machine designed for integration and optimization with Cat grapples
  •     

  • Powerful, multi-functioning hydraulics, combined with strong machine performance ensure work tools function quickly and smoothly to complete work faster

Performance

        

  • Cat 152 kW (204 hp) C7.1 ACERT™ Tier 4 Final engine with increased horsepower maintains maximum performance under load
  •     

  • Strong hydraulic horsepower for efficient implement performance and greater productivity
  •     

  • An increase in swing torque of 19 percent on General Forestry models and 18 percent on Log Loader models, provides added power to move trees, which enables more efficiency and productivity
  •     

  • Heavy lift mode features increased lift capacity to handle larger payloads with improved control
  •     

  • 989 L (261 gal) counterweight fuel tank for extended machine operation and maximum uptime
  •     

  • Machine width and track length designed for stability in varied logging applications

Application Versatility

        

  • Boom arrangements and hydraulic systems for specific applications enable more effective road building, loading, processing, shoveling, or millyard stacking
  •     

  • New track options meet shovel logging and low ground pressure application requirements
  •     

  • Ground saw hydraulics are available for log loader applications
  •     

  • Two premium rear entry cab choices, available on the Log Loader, include a 1219 mm (48 in) or a 1829 mm (72 in) cab forward riser
  •     

  • Purpose built processor cab option that includes 19 mm (0.75 in) front windows

Reliability and Durability

        

  • Variable pitch, reversing cooling fan maintains optimum fluid temperature in heavy duty forestry applications
  •     

  • Cooling capability increased 12 percent for trouble-free operation
  •     

  • Purpose built upper frame, high-wide carbody, robust linkage configurations, and heavy-duty enclosures are reinforced with thick doubler plates, extra gussets, and other reinforcements for structural integrity in severe applications
  •     

  • Large, 216 mm (8.5 in) pitch (336 HEX), grease lubricated tracks, provide excellent life in variable forestry working conditions
  •     

  • Validated and proven excavator technologies ensure overall machine reliability

Serviceability

        

  • One-piece engine hood design, with two opening angles, allows easy access to engine and cooling compartments
  •     

  • Side-by-side engine and hydraulic coolers are easy to access for cleaning, while reduced cooling fins per inch allows better debris flow-through and reduced clogging potential
  •     

  • 0.56 m3 (19.8 ft3) of storage space at ground level, provides ready access to tools, equipment, and supplies that operators use daily
