Fuel Efficiency

Fuel Efficiency
  • The C3.4B U.S. EPA Tier 4 Final/EU Stage IV engine burns up to 14% less fuel than the model it replaces, the 311D.
  • The engine is equipped to run on up to B20 biodiesel fuel.
  • Two power modes, high power and eco mode, help operators manage fuel consumption.
  • Auto engine idle shutdown saves fuel, reduces emissions, and extends service intervals.


  • Reduced radius is ideal for work in space-restricted areas.
  • Site prep and finishing work are quick and easy with a wide range of Cat work tools.
  • Utility work is fast and flawless with a Cat bucket and compactor.
  • A coupler lets you swap between attachments in seconds without leaving the cab.
