MORE PERFORMANCE, LESS FUEL

Increase operating efficiency up to 45 percent with standard Cat technologies that lower operator fatigue and operating costs, including fuel consumption and daily maintenance.
Get up to 10 percent higher fuel efficiency – more work per unit of fuel – than the Cat 349F excavator.

EFFICIENCY AND PRODUCTIVITY

Boost productivity up to 45 percent versus traditional grading with standard Cat GRADE with 2D system – includes indicate-only and laser capability.
Standard Grade Assist: Stay on grade – simply and effortlessly – with single-lever digging.
Set your desired bucket angle and let Bucket Assist automatically maintain the angle in sloping, leveling, fine grading, and trenching applications.

WORK IN COMFORT

Choose between Deluxe and Premium cabs – both with automatic climate control.
Stay warm with the Deluxe seat; stay warm and cool with the Premium seat.
Get in and out of the cab easier using the tip-up left console.
Advanced viscous mounts reduce cab vibration up to 50 percent over previous excavator models.

SIMPLE TO OPERATE

Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
Program each joystick button, including power mode, response, and pattern, using Operator ID; the machine will remember what you set each time you go to work.
Automatic hydraulic oil warm up gets you to work faster in cold temperatures and helps prolong the life of components.

REDUCED MAINTENACE COSTS

Expect up to 15 percent less maintenance cost than the 349F due to extended service intervals. (Savings calculated over 12,000 machine hours.)
Check hydraulic system oil and easily drain fuel system water and fuel tank water from ground level.
Track your excavator’s filter life and maintenance intervals via the in-cab monitor.

BUILT-IN SAFETY FEATURES

Standard 2D E-Fence integrated right out of the factory prevents the excavator from moving outside of operator-defined set points.
Lift Assist helps you avoid tipping by letting you know if your load is within the excavator’s safe working range limits.
The standard ROPS cab meets ISO 12117-2:2008 requirements.

MORE PERFORMANCE, LESS FUEL

Increase operating efficiency up to 45 percent with standard Cat technologies that lower operator fatigue and operating costs, including fuel consumption and daily maintenance.
Get up to 10 percent higher fuel efficiency – more work per unit of fuel – than the Cat 349F excavator.
The C13 engine can run on biodiesel up to B20 and meets U.S. EPA Tier 4 Final, Japan 2014, and Korea Tier 4 Final emission standards.
Match the excavator to the job with three power modes – Power, Smart, and Eco. Smart mode automatically matches engine and hydraulic power to digging conditions, providing max power when needed and reducing power when it isn’t to help save fuel.
The new high-efficiency hydraulic fan cools the engine on demand to help reduce fuel consumption; available reverse function makes it easy to keep cores clean.
New self-sharpening Advansys™ bucket tips increase production and lower costs.
Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
Don’t let the temperature stop you from working. This excavator has a high-ambient capability of 52° C (125° F) and cold start capability of –18° C (0° F).
