Cat® C6.6 Engine with ACERT™ Technology

ACERT™ Technology manages combustion using a combination of air management, precise fuel delivery and careful timing in order to lower emissions and meet U.S. EPA Tier 3 engine emissions requirements.

Fumes Management System

The ventilation system draws fumes from the conveyor tunnel as well as the auger chamber and redirects them away from the operator for a more comfortable working environment.

High Capacity Cooling System

The deck-mounted cooling system provides a cool environment by exhausting hot air toward the hopper, away from operators and ground personnel.

Operator Comforts for a Productive Environment

The dual operating stations offer the best-in-class comfort, visibility and ease of use.

Advisor Display Simplifies Operation

The left operating console includes the Advisor Display that provides many unique features to assist the operator.

Mobil-trac™ Undercarriage Performs in All Applications

The Mobil-trac™ undercarriage provides superior durability while delivering unmatched mobility, ride, and traction in a variety of conditions.

Steel Track Undercarriage

The steel track undercarriage is available as an economic alternative to the Mobil-trac.

Independent Material Handling System Promotes Hands-Free Operation

The gateless material handling system promotes hands-free operation by providing features such as ratio control dials, and independent control of each auger and each conveyor.

Generator System Provides Quiet Power

The high capacity generator provides power for the electric screed heat, auxiliary lights and job site tools.

Serviceability Features That You’ve Come to Expect

Simplified service means more time spent paving and less time spent on maintenance.

Screeds That Deliver Quality

Cat pavers are available with vibratory and/or tamper bar screeds. Vibratory screeds are available with either front or rear-mounted extenders. Cat screeds provide even material flow and unparalleled stability that result in smooth, high quality mats.
