MAXIMIZE PERFORMANCE

  • Cat C7.1 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 configuration 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

MOVE MORE WITH LESS FUEL

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

OPTIONS TO MEET YOUR NEEDS

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

HEAVY DUTY CONSTRUCTION

  • 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

SAVE ON SERVICE AND MAINTENANCE

  • 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

BETTER COMFORT AND CONTROL

  • Premium fit and finishes to maximize operator experience
  • Fully adjustable, air ride cab seat that includes heating and cooling capability for comfort and reduced operator fatigue
  • LED lights increase visibility
  • Rear entry cab option provides improved access on a fully lit platform through the use of a key FOB
  • Rear entry cab window design improves visibility for shovel logging and other applications
  • Rear entry cab includes a new innovative cab lock down system that minimizes transport time and improves uptime
  • Tool control software as standard equipment for swapping and selecting tools quickly and efficiently
  • Cat Product Link™ allows for remote location of a machine and enables tracking of fuel consumption and other events
