  • 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
