C15 Engine with ACERT™ Technology

Powerful Cat C15 ACERT engine meets US EPA Tier 3 and EU Stage IIIA emission standards.

Robust Cooling System

Provides cool air intake to maximize fuel efficiency and minimize emissions. An on -demand variable speed fan draws ambient air from a separate compartment in front of the engine through the cooling package. The exhaust air exits from the front of the machine, maintaining a cool engine compartment.

Electronically Controlled All-wheel Drive

Hydrostatic drive system has four pumps and four motors that are electronically controlled for optimized traction in extreme conditions.

Four Steering Modes

The RM500B provides four steering modes: Front Steer, Rear Steer, Crab Steer and Coordinated Steer. This endows the machine with remarkable maneuverability.


The cab provides excellent year-round comfort. The cab is fully pressurized and includes climate control. Plenty of glass provides ample views to optimize operator precision. Two doors allow the operator to enter the cab from either side of the machine.

Operator's Station

Ergonomic design emphasizes operator comfort, visibility and easy operation. The cab slides side-to-side, enhancing visibility to the cutting edge to increase versatility and productivity while reducing operator fatigue.

Electronic Control Modules

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

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. Designed for deep-cut soil mixing where pulverization and gradation is of lesser importance than higher working speeds. Performs well in cohesive soils and has a secondary application of surface mining for non-engineered substances such as coal, shale, or limestone.

Soil Rotor

Designed primarily for soil stabilization applications in semi-cohesive or granular soils. An ideal choice for mixing additives with semi-cohesive or granular materials where soil gradation is critical. Also can perform light reclamation applications where the asphalt layer is thin and deteriorated.


The RM500B features ground level access to most service items. Less time on maintenance means more time on the job.
