Features

1
Folding Secondary Conveyor
Allows reduced shipping length for easier transportation and can be equipped with optional scale and camera so the operator can monitor truck fill.
2
CAN-Bus System Architecture
Industry standard components reduce wiring and interconnections providing greater reliability and ease of troubleshooting.
3
Engine
Mounted behind the fuel tanks at the optimum center of gravity location - putting the weight closer to the cutter for more stability & less vibration during milling. Moving the engine away from the operator platform reduces noise and heat, increasing operator comfort & safety.
4
Engine Mounted Pumps
Our industry exclusive front engine mount pump drive is a highly reliable, proven design that allows belts and pumps to be changed easily from the front of the engine.
5
Easy Access
Fully opening gull wing engine cover doors lift up to reveal all service items such as air cleaners, batteries, belts and filters.
6
Primary & Secondary Conveyors
CMI’s industry leading 42” wide primary & secondary discharge belts provide greater material evacuation from the housing allowing the machine to operate at a faster, more efficient cut rate with far less cutting tooth and holder wear.
7
Fuel and Water Storage
Largest storage capacity in its class results in longer running time and less downtime.
8
Skid Mounted Powerpack
Side platforms allow walk-in access to the engine compartment. The skid mounted engine has clearance from below for easy access for maintenance and repair.
9
Slim Profile
A slimmer, streamlined profile provides greater visibility and a better sight line for the operator to the ground.
10
Power Lift Rear Door
Fan assembly is lifted with hydraulically actuated rear door allowing ground level access to maintain cooling system.





Touch Screen Control System

Standard control package features the largest (12”) high resolution, high contrast graphic control screen in the industry providing excellent visibility during day and night operation.



Cutter Drum

Full range movement lift and hinge cutter door provides efficient and easy access for tooth change out and replacement.



Conveyor Components

Catenary style suspended idlers with rubber impact rings provide for easy maintenance over fixed idler designs.



Modular System Design

Our modular control system design approach using common parts provides redundancy, reduces spares requirements and allows us to easily add additional functions and control options.



Easy Maintenance

Centralised lubrication points make regular maintainence simple while all engine fluids fill/check locations are easily reached via walkways and oil filters are easily accessible from the ground.



Easy Troubleshooting

Multiple lower level screens identify the location of problems and provide simple “smart” status codes to allow for easy maintenance and troubleshooting.
