Under The Hood

  • A new water cooled, Variable Flow Turbocharger, provides added durability and excellent engine response.
  • The Komatsu Diesel Oxidation Catalyst provides 98% passive regeneration and does not interfere with machine operation.
  • New auto-idle shutdown and economy modes that help reduce idle time and save fuel.

Machine Performance Enhancements

  • New standard, operator-selectable, automatic reverse grading mode enables automatic blade control, per customer feedback.
