Feel more comfortable in the cab while you work with reduced cab vibrations from advanced viscous mounts.
Control the excavator comfortably with easy-to-reach controls.
Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, bottle holder, and coat hook are also provided.
Bluetooth® integrated radio allows for seamless mobile phone connection to listen to music, podcasts, and hands-free calling.
Easily adjust to your ideal temperature with the touchscreen monitor or jog dial.

Quickly check and service your machine with daily maintenance points accessible from ground level.
Check the engine oil level quickly and safely from the ground.
Save up to 10 percent in maintenance parts with longer lasting filters.
Track your machine's filter life and maintenance intervals on the in-cab monitor.
Two levels of fuel filtration protect the engine from dirty diesel.
The hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000-hour replacement interval - 50 percent longer than previous filter designs.
Scheduled Oil Sampling (S·O·SSM) ports are located at ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.
Boost productivity with proactive service reminders. The Integrated vehicle health management system alerts the operator with step-by-step service guidance along with parts needed so you don't experience any unnecessary downtime.

Start the engine with the push-to-start button, a Bluetooth key fob, or the unique operator ID function.
Program your power mode and joystick preferences using operator ID; the excavator remembers your settings each time you go to work.
Navigate quickly on the standard high-resolution 254 mm (10 in) touchscreen monitor or with the aid of the jog dial control.
Not sure how a function works or how to maintain the excavator? Simply access the operator's manual on the touchscreen monitor.
The axle locks at zero speed and unlocks when the travel pedal is activated. The axle can also be manually locked with a button on the right-hand console.
Tiltrotator attachments--ours or other brands--work seamlessly with Cat 2D Grade, Assist, Payload, and E-Fence . With no additional hardware required, all you have to do is simply select "Third Party Tiltrotator System Installation" in the monitor, do the calibration, and get to work.
Cat continues to improve user interface functionality for operators of all skill levels. The touchscreen monitor is an easy-to-use operating tool that presents the jobsite dashboard with an intuitive format. Productivity applications are displayed in grid-view to read on-the-go, and touchscreen navigation is programmed to make sure job performance continues without any hold ups.

Access daily maintenance points from ground level.
Keep your excavator secure with operator ID. Use your PIN code on the monitor to enable the push-button starting feature.
The standard ROPS cab meets ISO 12117-2:2008 requirements.
Enjoy better visibility into trenches, in each swing direction and behind you, with the help of smaller cab pillars, larger windows, and a flat engine hood design. Rearview and sideview cameras are standard.
The service platform design provides easy, safe, and quick access to the upper service platform; the service platform steps use antiskid punch plate to prevent slipping.
The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
Travel and swing lock prevent front linkage from moving as you travel.
Ground level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
Make service work easier and safer with optional inspection lighting. With the flip of a switch, lights will illuminate the engine, pump, battery, and radiator compartments to enhance visibility.

Boost Efficiency and Productivity with Integrated Cat Technologies

Boost productivity versus traditional grading with optional Cat Grade with 2D system.
Optional Cat Payload helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material--with a bucket and thumb combination or grapple and clamshell attachments--and get a real-time weight estimate without swinging.
Combine Payload with VisionLink® and remotely manage your production targets or take payload data with you.
Upgrade to our dual antenna GNSS for maximum grading efficiency. The system lets you create and edit designs on the touchscreen monitor while you’re on the job, or you can have the plan design sent to the excavator to make your work easier. Plus, you get added benefits of avoidance zones, cut and fill mapping, lane guidance, and augmented reality along with advanced positioning capability.
Optional Grade Assist helps you 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
Optional 2D E-fence is integrated right out of the factory to prevent the excavator from moving outside operator defined set points.
All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica. Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.

The Cat® C4.4 engine meets U.S. EPA Tier 4 Final, EU Stage V, and Korea Tier 5 emission standards.
The M318 emits up to 10% less CO2 than the M318F.*
Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels*** up to: 20% biodiesel FAME (fatty acid methyl ester)** or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels.Refer to guidelines for successful application. Please consult your Cat dealer or "Caterpillar Machine Fluids Recommendations" (SEBU6250) for details.
Match the excavator to the job using power modes including ECO mode that reduces engine speed and hydraulic power for applications not requiring full hydraulic power - helping you to save fuel and greenhouse gas emissions.
Cat Grade technologies combine advanced guidance with optional automated machine control helping you reach grading targets while helping to reduce fuel burn and greenhouse gas emissions by improving efficiency, job site productivity, and accuracy.
Cat® Payload for excavators provides on-the-go material weighing which helps reduce fuel burn by improving loading efficiency, job site productivity, and eliminating trips to the scale.
Cat 2D E-fence keeps the front linkage within a predefined work area to avoid hazards such as traffic - not only helping keep personnel safe but also helps you avoid repairs, downtime, and costly job site fines.
Don't waste fuel idling. Cat VisionLink® online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions. VisionLink® displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
Extended maintenance intervals not only reduce downtime but can decrease the amount of fluid and filters that are replaced over the life of the machine. The hydraulic oil filter can now be replaced every 3000 hours - 50% longer than previous designs.
Remote Flash helps to minimize downtime and maintenance time while keeping your asset running with maximum efficiency. Alerts for machine updates are sent virtually from your Cat dealer and updates can be deployed without a dealer technician needing to be onsite.
Remote Troubleshoot helps to decrease maintenance time and keep your machine running with maximum efficiency by allowing your Cat dealer to virtually test the machine while working. Once a problem is identified, a technician can fix it the first time, saving time and money.

*All comparisons to M318F. Productivity, fuel and CO2 emissions vary by application. CO2 emissions calculations based on a reference work cycle using 2.2 U.S. gallons per hour of #2 U.S. diesel fuel based. Applies IPCC2006 methodology using U.S. EPA Emissions Hub emission factors. Includes DEF (diesel exhaust fluid) related CO2. Fuel measurements are at 15°C. Estimated average fuel consumption improvements are based on tests or Product Link® data where available. Productivity improvements are based on test data.
**Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).***Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
