C15 Engine with ACERT™ Technology

A combination of innovations working at the point of combustion, ACERT Technology optimizes engine performance while meeting U.S. EPA Tier 3 and European EU Stage IIIa emission regulations for off-road applications.

Operator's Station

Ergonomic design emphasizes operator comfort, visibility and easy operation. The platform slides side-to-side to increase versatility and productivity while reducing operator fatigue.

Operational Controls

All machine controls, switches and gauges are positioned to minimize operator fatigue and maximize productivity.

Cab (Optional)

Optional cab can increase machine utilization and provides greater year-round comfort in extreme environment conditions. The cab is fully pressurized and includes air conditioning.

Electronic Control Modules

Reliable field-proven technology makes machine operation simple and self-diagnostics simplifies troubleshooting.

Dual Pump Propel System

Hydrostatic drive provides balanced full-time tractive effort to each drive motor.

All-Wheel Drive

A separate hydraulic pump provides hydraulic flow to large displacement motors on each rear wheel. The system is designed to propel the machine with full-time all-wheel drive.

Rotor Drive

Maximum production with high reliability. A Cat powershift transmission provides three rotor speeds for maximum performance in a variety of materials and cutting depths.

Mixing Chamber

The mixing chamber is a heavy-duty hood with large volume to handle deep mixing. Ensures depth control, proper sizing and thorough blending of reclaimed materials.

Hydraulic Front Door

Heavy-duty front door is ideal for peak efficiency on soil stabilization, bio-remediation or mixing passes on asphalt reclamation.

Universal Rotors

Two universal rotors for different tasks.

Combination Rotor

Designed primarily for soil stabilization applications in cohesive soils.

Soil Rotor

Designed primarily for soil stabilization applications in semi-cohesive or granular soils.


Less time on maintenance means more time on the job.
