Not all features are available in all regions. Please check with your local Cat dealer for specific offering availability in your area. Build Number: 06C

High Performance, Low Fuel Consumption

        
  • Powerful digging force and strong swing torque enable the use of large buckets up to 3.2 mยณ (4.2 ydยณ) 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 โ€“ 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 isnโ€™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.

Boost Efficiency And Productivity

        
  • Boost productivity up to 45 percent with optional Cat Grade technology.
  •     
  • 2D Grade indicates depth and slope on the monitor with auditor alerts.
  •     
  • Grade Assist helps you stay on grade โ€“ simply and effortlessly โ€“ with single-lever digging.
  •     
  • Automatically stop excavator swing at operator-defined setpoints in truck loading and trenching applications with Swing Assist, which will help you use less effort and consume less fuel.
  •     
  • Cat Payload helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material and get a real-time weight estimate without swinging.
  •     
  • Combine Payload with VisionLinkยฎ and remotely manage your production targets. The monitor's USB port lets you download results from one shift all the way up to 30 days of work so you can manage your progress without needing an internet connection or VisionLink subscription.
  •     
  • Upgrade to Cat Grade with Advanced 2D and create and edit grade designs with ease on a second high-resolution 254 mm (10 in) touchscreen monitor.
  •     
  • Want a 3D system to improve your digging results? Caterpillar's single antenna global navigation satellite system (GNSS) makes it easy by giving you visual and auditory guidance to grade. Plus you can create and edit designs on the touchscreen monitor while youโ€™re on the job. If your application calls for a dual antenna system, itโ€™s easy to upgrade.
  •     
  • Upgrade to our dual antenna GNSS for maximum grading efficiency. The system lets you create and edit designs on the touchscreen monitor while youโ€™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.
  •     
  • 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.
  •     
  • 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.
  •     
  • 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.
  •     
  • Standard VisionLinkยฎ provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data on demand through VisionLink online interface, helping you improve jobsite efficiency with lower operating costs.
