  • The C4.4 engine meets U.S. EPA Tier 4 Final/EU Stage IV emission standards. It is powerful and efficient, and it can run on biodiesel up to B20.
  • Advanced control automatically manages pump and engine speed for maximum efficiency.
  • Two power modes, high power and eco mode, help you actively manage fuel consumption.
  • Engine idle shutdown saves fuel, and extends service intervals.


  • 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.
  • See the whole money-making attachment line for your machine at www.cat.com/attachments.


  • The roll-over protective structure (ROPS) certified cab is quiet and comfortable.
  • Automatic climate control helps maintain consistent cab temperature.
  • Joystick consoles and armrests are adjustable.
  • Seats are adjustable and feature air suspension (Europe, Australia, New Zealand and Pacific Islands) with an optional heater.
  • The LCD monitor is easy to navigate and programmable in 42 languages.


  • Many routine service and maintenance points can be accessed from ground level reducing the time taken to check and service your machine.
  • Wide service doors make for easy access.
  • Filters are grouped to reduce service time.
  • The cooling package is designed to prevent plugging, make blowing off debris easy.


  • Cat technology improves job site efficiency.
  • Optional Cat Grade Control helps you create a level base and precise slope with ease.
  • Product Link™/VisionLink® connects owners to the machine, providing access to location, hours, fuel consumption, idle time, events, and diagnostic codes.


  • The large swing bearing is secured with elongated bolts to help handle the most swing-intensive work.
  • Robot welded, Caterpillar designed boom and sticks are built for long service.
  • Greased track link between pins and bushings increases undercarriage life and reduces noise.


  • The hydraulic activation lever locks out all hydraulic functions.
  • Handrails, anti-skid plating, and countersunk bolts reduce slipping and tripping.
  • A ground-level engine shutoff switch shuts down the engine in case of emergency.
  • Standard rearview camera and mirrors enhance visibility.
  • The side-view camera enhances visibility on the boom side of the machine to help make operators more effective and efficient (Europe only).
