BENEFITS & FEATURES
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 reduces fuel consumption
  • Larger hydraulic pump allows engine to operate at lower rpm with increased performance to maximize efficiency
  • Component layout and back-to-back main hydraulic control valve reduces oil flow restrictions and aids in greater fuel economy
  • Machine designed for integration and optimization with SATCO® work tools and Cat® grapples
  • Powerful, multi-functioning hydraulics, combined with strong machine performance ensure work tools function quickly and fluidly to complete work faster

Performance


  • Cat 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 18 percent, 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

Stability


  • Wider undercarriage, by 203 mm (8 in), improves stability for increased lift and swing capabilities
  • Heavy duty counterweight as standard equipment ensures machine platform is stable in varied 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
  • Purpose built processor cab that includes 19 mm (0.75 in) front windows

Reliability and Durability


  • Variable pitch, reversing cooling fan maintains optimum fluid temperatures in heavy duty forestry applications
  • Cooling capability increased 12 percent for trouble-free operation
  • High-wide carbody features double-supported carrier rollers, reinforced idler mounts, heavy-duty top hat, extra gussets, and thick doubler plates for structural integrity in severe applications
  • Larger 203 mm (8 in) pitch Positive Pin Retention 2 links (329 HEX) provide greater life in variable forestry working conditions
  • Purpose-built upper frames provide increased life with box section members, thick doubler plates, reinforced swing drive mounts, rugged door components, and 5 mm (0.2 in) sheet metal
  • Linkage configurations incorporate internal baffle plates, large box sections, and thicker plating to increase service life
  • 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 provide easy access for cleaning, while reduced cooling fins per inch allows better debris flow-through to reduce clogging potential
  • 0.28 m3 (10 ft3) of storage space at ground level, gives ready access to tools, equipment, and supplies that operators use daily

Operator Comfort and Technology


  • Fully adjustable, air ride cab seat that includes heating and cooling capability for comfort and reduced operator fatigue
  • LED lights increase visibility
  • Cat Product Link™ allows for remote location of a machine and enables tracking of fuel consumption and other events

Work Tools


  • Both machine models are optimized for a wide variety of processing and harvesting heads, grapples, heels, quick couplers, and thumbs
