  • Use up to 15 percent less fuel than the 315F to keep you moving and productive on the jobsite.
  • Work confidently in space-restricted areas. Dig, swing, and dump within a working space of 3.96 m (12 ft 11 in).
  • Easily work on slopes and move around the jobsite with 10 percent more swing torque.
  • The advanced hydraulic system provides the optimum balance of power and efficiency while providing the control needed for precise digging requirements.
  • Smart mode meets your power needs by automatically matching engine and hydraulic power to digging conditions.
  • Get higher production in demanding applications, easier penetration into piles, and faster cycle times with Cat® Advansys™ bucket tips. Quickly change tips with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
  • The Cat C3.6 engine meets U.S. EPA Tier 4 Final and EU Stage V emission standards.
