    •     
  • Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to help increase undercarriage life.
    •     
  • Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
    •     
  • Optional Advansys™ bucket tips* increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
    •     
  • S·O·SSM oil sampling ports are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.
    •     
  • Using Cat® genuine oil and filters and doing typical S∙O∙S monitoring will extend the current service interval, giving you more uptime.  

*Not available in all regions. Please check with your local Cat® dealer for specific offering availability in your area.

Low Owning and Operating Costs

        
  • The excavator uses less fuel than the 320D2 L in similar applications.
    •     
  • Match the excavator to the job with a choice of two modes: Power and Smart. Power mode provides full-time maximum output. Smart mode automatically matches engine and hydraulic power to digging conditions to help conserve fuel without impacting production.
    •     
  • VisionLink™ provides actionable data insights for all assets - regardless of fleet size or equipment manufacturer.* Review equipment data from your desktop or mobile device to maximize uptime and optimize assets. Dashboards provide information such as hours, miles, location, idle time, and fuel utilization. Make informed decisions that lower costs, simplify maintenance, and improve safety and security on your jobsite.
    •     
  • Save fuel with Automatic Engine Control (AEC). It reduces engine speed when the machine is not under load to minimize fuel consumption.

* Data field availability can vary by equipment manufacturer.
