Fuel Saving, Job Matched Performance
  • Use up to 10 percent less fuel than the 316F to keep you moving and productive on the jobsite.
  • The advanced hydraulic system provides the optimum balance of power and efficiency while providing the control needed for precise digging requirements.
  • Smart mode meets your power needs by automatically matching engine and hydraulic power to digging conditions.
Lower Maintenance Costs
  • Expect up to 20 percent less maintenance costs than the 316F.
  • 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.
World-Class Versatility
  • Do more with one machine. The 317 GC’s expanded work tool offering helps you tackle your jobsite’s various applications with ease.
  • Work efficiently with the 317 GC's large working envelope. Move more material without having to reposition the machine.
  • Easily move the excavator from jobsite to jobsite. The 317 GC’s weight makes it easily transportable without compromising on the performance you need.
Work in Comfort
  • Increase operator productivity with an all-new, larger cab.
  • The cab has a wide seat that adjusts for operators of all sizes.
  • Advanced viscous mounts reduce cab vibration.
  • Control the excavator comfortably with easy-to-reach controls, all located in front of you.
  • Stow your equipment with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles.
Reliable, Whatever the Environment
  • Don’t let the temperature stop you from working. The 317 GC has a standard high-ambient temperature capability of 52°C (125°F) without derate and an optional cold-start capability of -25°C (-13°F).
  • Automatic hydraulic warm-up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
Simple to Operate
  • Start the engine with the push of a button, a Bluetooth key fob, smartphone app, 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.
Safety
  • 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.
  • The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
  • A ground-level shutoff switch stops all fuel to the engine and shuts down the machine when activated.
Fuel Saving, Job Matched Performance
  • Use up to 10 percent less fuel than the 316F to keep you moving and productive on the jobsite.
  • The advanced hydraulic system provides the optimum balance of power and efficiency while providing the control needed for precise digging requirements.
  • Smart mode meets your power needs by automatically matching engine and hydraulic power to digging conditions.
