Benefits and Features

  • Powerful Cat® C18 twin-turbo engine meets regional emission standards
  • Smooth and efficient operation with Automatic Idle Control and multiple rotor speeds optimize output and demand on the engine
  • High capacity cooling system keeps engine at ideal temperatures for optimal fuel efficiency and lower emissions
  • Automatic load sensing on the rotor adjusts milling speed to prevent stalls and optimize production

  • Reliable track undercarriage leverages proven designs from Cat dozers and an automatic tensioning system to ensure consistent performance and longer track life
  • Robust propel system features two independent propel pumps to drive two crawler tracks each, in a high-traction, cross-drive pattern
  • Automatic traction control maintains consistent speed in the most challenging applications
  • Four steering modes with advanced alignment and tracking provides precise steering geometry and reduces track pad wear
  • Ability to electronically switch between rotor speeds during operation

  • Operate in comfort with height-adjustable operating consoles and intuitive, ergonomic controls
  • Retractable handrails stow and redeploy easily when approaching obstacles
  • Work day or night with backlit keypads and well-lit work areas
  • Upgrade operator stations with optional suspension seats that reposition for improved visibility and comfort
  • Optional remote cameras enhance visibility to the cutting edge and conveyor
  • Optional powered canopy stows easily during operation to clear overhead obstacles and optional windscreens can be added for increased comfort
  • Maximize dust removal from the working areas with the optional dust abatement system

  • The rotor drive system features a heavy-duty dry clutch, automatic belt-tensioning to prevent slippage and two high tensile (five-rib) belts to drive the rotor
  • Reinforced cutting chamber offers enhanced durability
  • Hardened full length side plate skis and anti-slab shoes reduce wear and maintenance

  • Achieve accurate, repeatable and automatic cutting precision with the integrated Cat GRADE with Grade and Slope system
  • Control boxes can be repositioned without the need to reconfigure settings
  • Obtain full control of grade and slope from any control box
  • Seamlessly swap between multiple grade sensors for uninterrupted accuracy during milling
  • Adjust the speed at which the rotor drops into the cut for optimal machine control
  • Set and automate transitions in/out of cuts and save settings for future jobs
  • Clear obstacles in the cutting path with ease using the obstacle jump feature
  • Enhance for full 3D milling operation (additional hardware required)

  • Cat System K rotors feature efficient material flow with an excellent cutting pattern for numerous applications
  • A dual taper retention design holds tool holders in place, without retaining pins or bolts, for faster bit changes
  • Reversible paddles and high strength alloys reduce wear and abrasion to extend rotor life
  • Optional diamond bits can extend replacement intervals up to 80 times longer than conventional carbide bits

  • Maintenance is easier and faster with large service doors and power hood for walk-in access to critical components
  • Maintenance-free track components and easy to replace track pads lower service costs
  • Standard ground-level controls and an optional hydraulically-operated rotor turning device simplify bit removal and replacement
  • Operate select machine functions during maintenance and service with the accessory drive system
  • Electrical system wiring is color-coded and numbered for easy identification and wrapped in a protective, abrasion-resistent nylon braid for longer life
  • Extended hydraulic oil service intervals: 3000 hours without oil sampling, 6000 hours with oil sampling
  • Track scheduled maintenance with Cat Product Link™ telematics services
  • Electronic Control Modules (ECMs) monitor machine systems to alert the operator of performance issues and can be paired with Product Link options to enable additional remote services with your local Cat dealer
  • Multi-piece, cartridge-style engine filters are environmentally friendly, reducing waste and lowering replacement costs
  • Convenient parts availability, dealer locations and service repair kits simplify ordering of high wear components
