C11 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 optional sliding platform slides side-to-side to reduce operator fatigue for increased productivity.

Operational Controls

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

Sliding 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.

Propel System

Hydrostatic drive provides balanced tractive effort to each drive motor.

Rear Wheel Drive (Optional)

Optional rear wheel drive includes a separate hydraulic pump and large displacement motors on each rear wheel. The system propels the machine with all-wheel drive.

Rotor Drive

Maximum production with high reliability. The mechanical rotor drive system provides three rotor speeds for maximum performance in a variety of materials and cutting depths.

Mixing Chamber

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 (Optional)

Optional 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.

Spade Rotor

Designed for soil stabilization applications.


Less time on maintenance means more time on the job.
