High Performance with Lower Fuel Consumption

• The excavator uses up to 20 percent less fuel than the 320D2 GC insimilar applications.
• Match the excavator to the job using power modes; let Smart mode
automatically match engine and hydraulic power to your digging conditions.
• The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
• Valve priority puts hydraulic pressure and flow where you command it to go for fast light- to medium-load cycle times.
• Meets U.S. EPA Tier 3/EU Stage IIIA/China Nonroad Stage III/
Brazil MAR-1 equivalent emission standards.
• Add auxiliary hydraulics to do more work with a range of Cat attachments.
• Product Link™ comes standard so you can remotely monitor machine health, location, hours, and fuel consumption on demand through the VisionLink® online interface.
