  • Up to 8% improvement in productivity.
  • Advanced Productivity Electronic Control System (APECS) allows
    the engine and transmission to communicate on a high level. This communication allows the machine to better utilize the power
    and torque the engine is producing. The net result is moving more
  • Machine Speed Limit feature replace stop gear selection.
  • Auto-Stall assists in quickly bringing the transmission to an
    operating temperature at start-up when the machine is working in a
    cold climate region.
  • Boost productivity with the Payload Estimator feature (optional
    attachment). Payload Estimator is an automatic feature when
    ordered with Sequence Assist.
  • Cat® Payload Estimator for scrapers is an earthmoving solution for
    optimal payload and jobsite efficiency. Payload Estimator achieves
    on-the-go weighing by using bowl lift cylinder pressure during the
    loaded haul segment. Payload Estimator is optimized to be used
    with Sequence Assist, which provides increased productivity with
    less operator effort.


  • Reduce up to 14 individual operator commands per cycle with
    Sequence Assist (optional attachment).
  • Steer with less effort with the newly designed high-pressure
    steering system.
  • Enjoy interior improvements and a more ergonomic work
    environment with a 21% larger cab than the G Series cab.
  • Intuitive, ergonomic controls keep operators focused on their work.
  • Maintain desired cab temperature with automatic temperature


  • Get in and out of the cab easier with the new powered access
    ladder system (optional attachment).
  • Enhance an operator’s awareness of site surroundings with the
    Work Area Vision System [WAVS (optional attachment)].
  • Differential lock engagement protection (standard) prevents
    the operator from engaging the differential lock when damage
    can occur.
  • Seat belt indicator provides visual and audible alerts when the seat belt is not in use.


  • Control the slip of the tractor tires with tire spin reduction
  • The spacious cab features easy, intuitive controls and excellent
    visibility. The cab provides a comfortable working environment for
    all-day operation.
  • Equipped with advanced cushion hitch software, the Cat Advanced
    Ride Management (ARM) seat suspension reduces end stroke
    movement of the load cylinder for a smoother ride.


  • Hit target grade faster and more accurately with Cat GRADE technologies. Finish jobs in fewer passes and with less operator effort, saving you time and helping to increase profit.
  • Product Link™ collects machine data that can be viewed online through web and mobile applications (optional attachment).
  • Access information anytime, anywhere with Vision Link®– use it to make informed decisions that productivity, lower costs,simplify maintenance, and improve safety and security on your jobsite.
  • Shorten the learning curve for inexperienced operators with Load Assist (optional attachment).


  • The new tractor hydraulic on-demand fan helps assist in lower fuel consumption.
  • Use fuel economy mode to assist in fuel savings.
  • The Cat C13 tractor engine and the Cat 9.3 scraper engine emit equivalent to U.S. EPA Tier 2/EU Stage II or U.S. EPA Tier 3/ EU Stage III, contributing to lower fuel consumption.
  • Using draft-arm overflow guards diverts material away from the bowl, retaining material and limiting spills onto the rear of the scraper.
  • No operator input is required with engine overspeed protection.
  • Cat Grade Control (optional attachment) intelligently ensures the machine does not cut below grade in a cut area or overfill in the fill area.
