PERFORMANCE AND PRODUCTIVITY

  • Cat C7.1 engine with increased horsepower maintains maximum performance under load
  • Strong hydraulic horsepower for efficient implement performance and greater 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

POWERFUL 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 pump allows 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

EXPAND YOUR CAPABILITIES

  • Boom arrangements and hydraulic systems for specific applications enable more effective road building, loading, processing, shoveling, or millyard stacking
  • New track option meets shovel logging application requirements
  • Two new premium rear entry cab choices, available on the Log Loader, include a 1219 mm (48 in) straight riser or a 1829 mm (72 in) cab forward riser
  • Purpose built processor cab option that includes 19 mm (0.75 in) front windows

RELIABILITY YOU CAN COUNT ON

  • Variable pitch, reversing cooling fan maintains optimum fluid temperature in heavy duty forestry applications
  • Cooling capacity increased 33 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 (349 HEX), grease lubricated tracks, provide excellent life in variable forestry working conditions
  • Validated and proven excavator technologies ensure overall machine reliability

SAVE ON MAINTENANCE TIME

  • 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
  • 0.71 m³ (25 ft³) of storage space at ground level, provides ready access to tools, equipment, and supplies that operators use daily

DESIGNED FOR OPERATORS

  • 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 safe access through 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 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
