Benefits and Features

  • Increased breakout forces and hydraulic power increase productivity by up to eight percent over the previous model.
  • The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
  • Reduce fuel consumption by up to five percent over the previous model.
  • Match your machine to the job with power modes. Let Smart mode automatically match engine and hydraulic power to working conditions. Power mode constantly provides maximum productivity, and ECO mode minimizes fuel consumption in less-demanding applications.
  • Get higher production in demanding applications, easier penetration into piles, and faster cycle times with Cat Advansys™ bucket tips. Quickly change tips with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
  • The Cat C4.4 engine meets U.S. EPA Tier 4 Final emission standards.
  • Don’t let the temperature stop you from working. The 317 has an optional cold-start capability of -25°C (-13°F).

  • Boost productivity up to 45 percent versus traditional grading with the standard Cat GRADE with 2D system – includes indicate-only and laser capability.
  • Dig with guidance to depth, slope, and horizontal distance to grade. You can set up to four different depth and slope targets to help save time and money.
  • Standard 2D E-Fence prevents your machine from moving outside operator-defined parameters.
  • Achieve precise load targets and increase loading efficiency with standard Cat PAYLOAD which provides on-the-go weighing and real-time estimates of your payload without swinging.
  • Standard Grade Assist keeps you on grade – simply and effortlessly – with single-level digging.
  • Set your desired bucket angle and let Bucket Assist automatically maintain the angle in slope, leveling, fine grading, and trenching applications.
  • Keep the tracks on the ground in lifting and hard digging applications with Boom Assist.
  • Automatically stop excavator swing at the operator-defined set points in truck loading and trenching applications with Swing Assist, saving you effort and fuel.
  • Upgrade to Cat GRADE with Advanced 2D to create and edit grade designs with ease on a second high-resolution 254 mm (10 in) touchscreen monitor.
  • Upgrade to Cat GRADE with 3D to create and edit designs with ease and see the front linkage’s full range of motion on a second high-resolution 254 mm (10 in) touchscreen monitor.
  • Know the excavator’s exact position relative to GPS and GLONASS systems. The machine automatically compensates for excavator pitch and roll caused by sloping ground conditions.
  • Use the excavator’s onboard cell technology to quickly connect to 3D services like Trimble Connected Community or Virtual Reference Station.
  • Remote Troubleshoot connects you to a dealer service pro to help solve your problem and quickly get you to work.
  • Remote Flash works around your schedule to ensure your machine’s software is up to date for optimal performance.
  • The Cat App helps you manage fleet location, hours, and maintenance schedules; it also alerts you for required maintenance and even allows you to request service from your local Cat dealer
  • Standard Product Link™ automatically and accurately collects data from your connected assets – any type and any brand. Information such as location, hours, fuel usage, productivity, idle time, maintenance alerts, diagnostic codes, and machine health can be viewed online through web and mobile applications.
  • 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.

  • Increase operator productivity with an all-new, larger cab.
  • Get in and out of the cab easier using the tip-up left console.
  • Advanced viscous mounts reduce cab vibration.
  • Control the excavator comfortably with easy-to-reach controls all located in front of you.
  • Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, document holder, and coat hook are also provided.
  • Use the standard radio’s USB ports and Bluetooth® technology to connect personal devices and make hands-free calls.

  • Start the engine with the push of a button, a Bluetooth key fob,or the unique Operator ID function.
  • Program your preferred power mode and joystick settings using your operator ID. The excavator will automatically remember your selections.
  • Navigate quickly on the standard high-resolution touchscreen monitor or with the aid of the jog dial control.
  • The Cat PL161 Attachment Locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The excavator’s onboard Bluetooth reader or Cat App on your phone will locate the device automatically.
  • Save time and energy with work tool recognition. A simple shake of the attached tool confirms its identity ensuring all attachment settings are correct, so you can get to work quickly and efficiently.
  • Not sure how a function works or how to maintain your machine? Simply access the operator’s manual through the touch screen monitor.
  • Make moving the excavator much easier with Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.

  • Expect up to 20 percent less maintenance costs over the previous model.
  • Quickly check and service your machine with all daily maintenance points accessible from ground level.
  • Check the engine oil level quickly and safely from the ground. Fill and check engine oil on top of the machine with a conveniently located second dipstick.
  • Track your machine’s filter life and maintenance intervals on the in-cab monitor.
  • The new 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.
  • S·O·SSM ports are located at ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.

  • Access all daily maintenance points from ground level – no need for you to climb on top of the machine.
  • The standard ROPS cab meets ISO 12117-2:2008 requirements.
  • A ground-level shutoff switch stops all fuel to the engine and shuts down the machine when activated.
  • A rearview and right-side-view camera are standard. Upgrade to 360° visibility to easily see objects and personnel around the excavator in a single view.
  • New service platform design provides easy, safe, and quick access to the upper service platform. Prevent slipping with the anti-skidpunch plate on the platform steps.
  • Optional boom and stick lowering check valves prevent reverse flow, keeping your front linkage securely in place should the hydraulic system unexpectedly lose power.
  • Brightly colored seatbelts allow easy recognition of properly utilized safety restraints.
  • Antennas have theft-prevention bolts; a special tool makes them easy to remove at the end of a shift.
