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.
CAN-Bus System Architecture
Industry standard components reduce wiring and interconnections providing greater reliability and ease of troubleshooting.
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.
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.
Fully opening gull wing engine cover doors lift up to reveal all service items such as air cleaners, batteries, belts and filters.
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.
Fuel and Water Storage
Largest storage capacity in its class results in longer running time and less downtime.
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.
A slimmer, streamlined profile provides greater visibility and a better sight line for the operator to the ground.
Power Lift Rear Door
Fan assembly is lifted with hydraulically actuated rear door allowing ground level access to maintain cooling system.
