INTEGRATED CAT TECHNOLOGIES
EXECUTE EFFICIENCY

- 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 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 replaces Top 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.
- Cat® Payload Estimator for scrapers is an earthmoving solution for optimal payload and job site 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.
- Steer with less effort with the newly designed High-Pressure Steering system.
- Reduce up to 14 individual operator commands per cycle with
Sequence Assist (optional attachment). - Enjoy interior improvements and a more ergonomic work
environment with a 21% larger cab than the 657 G-Series cabs. - Intuitive, ergonomic controls with multifunction display keep operators focused on their work.
- Maintain desired cab temperature with Automatic
Temperature Control.
- 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
optional Work Area Vision System (WAVS). - Ground level access to fuel fill and daily maintenance points.
- Seat belt indicator provides visual and audible alerts when the
seatbelt is not in use. - Advanced Cushion Hitch allows the cushion hitch to prevent
end stroke by having the ability to predict end stroke events
and manage the rate of dampening, resulting in reduced hitch
maintenance and improved operator ride in rough conditions.
- Cat Advance 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.

- Access information anytime, anywhere with Vision Link® –use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety and security onyour jobsite.
- Product Link™ collects machine data that can be viewed online through web and mobile applications (optional attachment).

- The Cat C18 tractor and C15 scraper engines meets U.S. EPA Tier 4 Final or EU Stage V emission standards, contributing to lowerfuel 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.
- The new tractor hydraulic on-demand fan helps assist in lower fuel consumption.
