High Performance, Low Fuel Consumption

  • Powerful digging force and strong swing torque enable the use of large buckets up to 3.2 m3 (4.2 yd3) for class-leading productivity.
  • Compared to the Cat 349-07, the 350 consumes up to 13 percent less fuel for lower operating costs and greater profit potential.
  • Match the excavator to the job with three power modes – Smart, Power, and Eco. Smart mode automatically matches engine and hydraulic power to digging conditions, providing maximum power when needed and reducing power when it isn’t to help save fuel. Power mode is maximum power all the time. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption.
  • Valve priority puts hydraulic pressure and flow where you command it to go for fast light- to medium-load cycle times.

Simple To Operate

  • Start the engine with a push button; use a Bluetooth key fob or Operator ID passcode.
  • 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.
  • Trouble cuting through tough material? Auto dig boost gives you an automatic power increase of 8 percent when you need it for better bucket penetration, shorter cycle times, and greater payloads.
  • Need more lift during your shift? Auto heavy lift gives you 8 percent more power exactly when you need it for as long as you need it.
  • Make moving the excavator much easier with optional Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers and pedals.
  • Navigate quickly on the standard high-resolution touchscreen monitor or with the aid of the jog dial control.
  • Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds – all to prevent wear and tear on the attachment and excavator.
