High Performance with Lower Fuel Consumption

        
  • Increase operating efficiency up to 45 percent with standard Cat Connect technologies that lower operator fatigue and operating costs, including fuel consumption and daily maintenance.
  •     
  • Get up to 15 percent higher fuel efficiency than the Cat 336D2 excavator—with more engine power, swing torque, and production.
  •     
  • The C9.3B engine can run on biodiesel up to B20 and meets China Nonroad Stage III and Brazil MAR-1 emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
  •     
  • Match the excavator to the job with three power modes—Power, Smart, and Eco. Smart mode automatically matches engine and hydraulic power to digging conditions, providing max power when needed and reducing power when it isn’t to help save fuel.
  •     
  • New high-efficiency hydraulic fans individually cool engine components on demand to help reduce fuel consumption.
  •     
  • The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.

  •     
  • Upgrade to optional Cat GRADE with 3D: Create and edit designs with ease and see the front linkage’s full range of motion on a second high-resolution 254 mm (10 in) touchscreen monitor.
  •     
  • Know the excavator’s exact position relative to GPS and GLONASS systems. The machine automatically compensates for excavator pitch and roll caused by sloping ground conditions.
  •     
  • Standard Product Link™ provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data on demand through VisionLink online interface, helping you improve job site efficiency with lower operating costs.
  •     
  • Know where your work tools are and how much you use them, as the machine tracks all attachments equipped with Cat TrackIt technology.

Work in Comfort in the All-New Cab

        
  • Choose between Comfort and Deluxe cabs—both with automatic climate control.
  •     
  • Sit in wide seats that adjust for all size operators; stay warm with the Deluxe heated seat.
  •     
  • Enjoy wide spacing between consoles for a more comfortable environment.
  •     
  • Get in and out of the cab easier using the tip-up left console (Deluxe cab only).
  •     
  • Advanced viscous mounts reduce cab vibration up to 50 percent over previous excavator models.
  •     
  • 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, overhead, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are also provided.
  •     
  • Use the standard radio’s USB ports and Bluetooth® technology to connect personal devices and make hands-free calls.

Simple to Operate

        
  • Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
  •     
  • Program each joystick button, including power mode, response, and pattern, using Operator ID.
  •     
  • Automatic hydraulic oil warm up gets you to work faster in cold temperatures and helps prolong the life of components.
  •     
  • Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor, or with the optional 254 mm (10 in) touchscreen monitor, or with the aid of the jog dial control.
  •     
  • A second 254 mm (10 in) monitor is available for the advanced grade control and Cat GRADE with 3D.
  •     
  • 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.

Maintenance

        
  • Expect up to 15 percent less maintenance cost than the 336D2. (Savings calculated over 12,000 machine hours.)
  •     
  • Check hydraulic system oil and easily drain fuel system water and fuel tank water from ground level.
  •     
  • Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
  •     
  • Change all fuel filters at a synchronized 1,000 hours. Oil and fuel filters grouped and located on right-hand side of machine for easy maintenance.
