  • Get the same productivity and results using up to 5 percent less fuel and work longer with a larger fuel tank over the M314F.
  • The Cat® engine matches your performance and production needs.
  • The engine meets U.S. EPA Tier 4 Final, EU Stage V, and S Korea 2014(Tier 4 Final) emission standards.
  • Travel between sites is easier with travel speeds up to 37 km/h(22 mph).
  • From dirt to asphalt, the excavator matches your needs to get the job done in a timely, efficient manner.
  • The advanced hydraulic system provides the optimum balanceof power and efficiency while giving you the control you need for precise working requirements.
  • With up to 15 percent more swing torque, you can get the job done faster to move on to the next one.
  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
  • Don’t let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of 52° C (125° F)and cold start capability of –18° C (0° F).


  • Choose between Deluxe and Premium cab options.
  • The Deluxe seat is heated and air adjustable while the Premium seat is heated, cooled and adjusts automatically.
  • Get in and out of the cab easier using the tip-up left console.
  • Feel more comfortable in the cab while you work with reduced cab vibrations from advanced viscous mounts.
  • Control the excavator comfortably with easy-to-reach controls.
