Efficient Performance

Cat® C9.3 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

Maneuverability and Control

Robust propel system features dual displacement planetary motors at each leg post, utilizing a cross-drive pattern for additional traction in straight cuts
Automatic traction control maintains consistent speed in the most challenging applications
Articulating right rear leg maximizes stability and traction in demanding cuts while enhancing flush cutting capability when needed

Comfortable Work Environment

Operate in comfort with a standard suspension seat, adjustable right arm console and intuitive, ergonomic controls
A sliding operator station extends up to 215 mm (8.5 in) to provide improved visibility to the cutting edge
Work day or night with backlit keypads and well-lit work areas

Durable Cutting System

The rotor drive system features a heavy-duty dry clutch, dual stage belt drive and automatic belt-tensioning to prevent slippage
Reinforced cutting chamber offers enhanced durability
Hardened full length side plate skis and anti-slab shoes reduce wear and maintenance

Boost Precision with Integrated Cat Technology

Achieve accurate, repeatable and automatic cutting precision with the integrated Cat GRADE with Grade and Slope system
The optional grade control box can be positioned in the operator station or on the back of the machine to enable interaction with the grade system from the ground level

System K Rotors

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

Simplified Service

Maintenance is easier with large service doors for 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

The optional grade control box can be positioned in the operator station or on the back of the machine to enable interaction with the grade system from the ground level
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)

System K Rotors

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

Simplified Service

Maintenance is easier with large service doors for access to critical components
