SIMPLE TO OPERATE

        

  • Start the engine with a push button; use a Bluetooth® key fob or the unique Operator ID function.
  •     

  • Program each joystick button, including power mode, response, and pattern, using Operator ID; the machine will remember what you set each time you go to work.
  •     

  • Make moving the excavator much easier with standard Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
  •     

  • Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.

WORK IN COMFORT

        

  • Get in and out of the cab easily with the standard tilt-up left console.
  •     

  • Deluxe cab with premium seat offers a heated and ventilated seat for year-round comfort.
  •     

  • Control the excavator comfortably with easy-to-reach controls all located in front of you.
  •     

  • Stow your gear with plenty of in-cab storage beneath and behind the seat and in the consoles.
  •

EASY MAINTENANCE

        

  • Long life fuel, oil, and air filters keep you working on the job longer.
  •     

  • Check the hydraulic system oil and easily drain fuel system water from ground level.
  •     

  • Track your excavator’s filter life and maintenance intervals via the in-cab monitor. The optional engine oil sensor tracks your oil levels to speed up your daily maintenance routine.
  •     

  • Change all fuel filters at a synchronized 1,000 hours. Filters are grouped together for easy maintenance.
  •     

  • The air intake filter with pre-cleaner has a high dust holding capacity.
  •     

  • The hydraulic oil filter provides improved filtration performance and anti-drain valves to keep oil clean when the filter is replaced.
  •     

  • The high-efficiency hydraulic fan has a standard automatic reverse function to keep cores free from debris, eliminating the need for any operator interaction.
