LATEST FEATURES
Cab Monitor Improvements
        
  1.  Continuously improved user interface allows for intuitive navigation, minimizing performance interruption with the easy-to-use touchscreen menu.
    2.     
  2. Identify apps quickly with a grid list view, abbreviated app names, and categorized menu options.
High Performance
        
  • The C9.3B engine generates more power than the 2020 model year 336 engine.
    •     
  • More power to the pumps, wider undercarriage, and heavy counterweight enable up to 10 percent more productivity.
    •     
  • Match the excavator to the job with three power modes – Power, Smart, and Eco. Power mode is maximum power all the time. Smart mode automatically matches engine and hydraulic power to digging conditions, providing maximum power when needed and reducing power when it isn’t to help save fuel. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption.
Efficiency Through Technology
        
  • Boost productivity up to 45% versus traditional grading with standard Cat Grade with 2D system – includes indicate-only and laser capability.​
    •     
  • Want a 3D system to improve your digging results? Caterpillar's single antenna global navigation satellite system (GNSS) makes it easy by giving you visual and auditory guidance to grade. Plus, you can create and edit designs on the touchscreen monitor while you’re on the job. If your application calls for a dual antenna system, it’s easy to upgrade.​
Take The Guesswork Out of Managing Your Equipment

    •     
  • Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
    •     
  • Cat VisionLink® displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
    •     
  • Remote Flash minimizes downtime and maintenance time while keeping your asset running with maximum efficiency. Alerts for machine updates are sent virtually from your Cat dealer and updates can be deployed without a dealer technician needing to be onsite.
    •     
  • Remote Troubleshoot decreases maintenance time and keeps your machine running with maximum efficiency by allowing your Cat dealer to virtually test the machine while working. Once a problem is identified, a technician can fix it the first time, saving time and money.

*Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).
**Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
