Benefits

Be More Productive

The Advanced Productivity Electronic Control System (APECS) allows
    the engine and transmission to communicate on a high level. This
    communication allows the machine to utilize better the power
    and torque the engine is producing. The net result is moving more
    material.
Use Ground Speed Control to set the desired top speed and the machine will find the gear that works best for the engine and the
transmission, providing a lower fuel burn.
The machine speed limit feature allows the machine to maintain a
set top speed instead of relying on top gear selector.
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.
Cat® Payload for scrapers is an earthmoving solution for optimal payload and jobsite efficiency. Cat Payload achieves on-the-go weighing by using bowl lift cylinder pressure during the loaded haul segment. Cat Payload is optimized to be used with Sequence Assist, which provides increased productivity with less operator
effort.
Enhance productivity through the usage of Cat Payload with
Sequence Assist.

Work in comfort

Reduce up to 14 individual operator commands per cycle with Sequence Assist.
Steer with less effort using 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 control.

Designed for Safety

Enhance an operator’s awareness of site surroundings with the work area vision system (WAVS).
Get in and out of the cab easier with the new powered access ladder system (optional attachment).
Seat belt indicator provides visual and audible alerts when the seatbelt is not in use.
Advanced Cushion Hitch allows the cushion hitch to prevent endstroke by predicting endstroke events and managing the rate of dampening, resulting in reduced hitch maintenance and improved operator ride in rough conditions.
The fuel fill, fuel filter, engine oil filter, engine oil change, and water drain are easily accessible at ground level.

Easy to Operate

The spacious cab features easy, intuitive controls and excellent visibility
. The cab provides a comfortable working environment for all-day
operation.
Cat advanced ride management (ARM) seat suspension reduces end
stroke movement of the load cylinder for a smoother ride.
Engine overspeed protection will automatically engage with no operator
input when the machine is in eighth gear. The machine will assist in slowing the machine speed by canceling the throttle command and engaging the engine compression brake.

Integrated Cat Technologies

Monitor, manage, and enhance jobsite operations.
Hit the 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 VisionLink® – use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety and security on your
jobsite.
Shorten the learning curve for inexperienced operators with
Sequence Assist and Load Assist (included with Cat Grade
attachment).

Execute Efficiency

The new tractor hydraulic on -demand fan helps assist in lower fuel consumption.
Using draft-arm overflow guards diverts material away from the bowl, preventing material from getting caught between the draft arms and the bowl sides.
Cat Grade (optional attachment) intelligently ensures the machine does not cut below grade in a cut area or overfill in the fill area.
