Enjoy interior improvements and a more ergonomic work environment. Intuitive, ergonomic controls with multifunction display keep operators focused on their work. Maintain desired cab temperature with automatic temperature control. EASY TO OPERATE See more EASY TO OPERATE 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. BE MORE PRODUCTIVE See more BE MORE PRODUCTIVE The Advanced Productivity Electronic Control System (APECS) allows the machine to better utilize engine power and torque. Set the desired top speed with Ground Speed Control, and the machine will find the gear that works best for the engine and the transmission, providing a lower fuel burn in speed reduced areas. 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 working in colder climates. DESIGNED FOR SAFETY See more DESIGNED FOR SAFETY Get in and out of the cab easier with the new powered access ladder system.
