Cat® C6.6 Engine with ACERT™ TechnologyACERT™ 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.
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.
High Ambient Temperature Cooling SystemThe standard, high-capacity cooling system provides efficient operation in high ambient temperatures. The system design provides quiet operation that benefits the operator and the surrounding environment.
Efficient Airflow DesignThe airflow design draws ambient air across the engine compartment and through the coolers. This design allows the exhaust air to exit toward the hopper in order to provide a cooler engine compartment and cooler operating environment.
Variable Speed FanThe variable speed fan is electronically controlled and hydraulically driven to provide on-demand cooling. This on-demand operation reduces engine power demand, lowers sound levels, and increases fuel efficiency.
Operator Comforts for a Productive Environment
The dual operating stations offer the best-in-class comfort, visibility and ease of use.
Dual Operating StationsThe dual operating stations incorporate fully equipped consoles, ground speed indicators, adjustable suspension seats with cup holders, armrests, and 76 mm (3") retractable seat belts.
Operator VisibilityThe dual operator's stations can be positioned in one of four different locations to provide optimum visibility. The stations can extend beyond the machine frame for good visibility when paving applications require precise control.
Tilting ConsolesThe tilting consoles increase operator comfort by offering multiple positions. A 12-volt power supply located on the right console allows for the use of accessories.
Advisor Monitoring System Simplifies Operation
The left operating console includes the Advisor Display that provides many unique features to assist the operator.
Advisor Monitoring System (AMS)The Advisor display provides access to a start-up checklist, operator preferences, engine and machine operating parameters, “Paving Calculator”, and “Paving by the Numbers.”
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.
Mobil-trac UndercarriageThe Mobil-trac undercarriage combines the flotation and traction benefits of a crawler suspension with the mobility and ride quality of a wheel-type paver. The Mobil-trac system includes a durable, high strength rubber track belt with a thick outer cover and internal layers of flexible steel cable.
Large Ground Contact AreaThe Mobil-trac’s ground contact area is 3020 mm (119") long and 406 mm (16") wide. This large footprint provides uniform weight distribution over the entire length of the belt.
Choice of Belt DesignsThe Mobil-trac system offers a tread-bar style belt or a smooth belt. Both belt styles are 58 mm (2.3") thick and provide good performance and wear characteristics, however, the smooth belt with beveled edges provides less disturbance on soft base materials.
Two Speed Planetary DriveA fixed displacement motor drives a two-speed planetary providing quick mobility around the job site.
Steel Track Undercarriage
The steel track undercarriage is available as an economic alternative to the Mobil-trac.
Quad Rear BogieA special quad bogie is positioned near the rear of the steel track in order to evenly distribute the load.
D3 Track RailsThe steel track system incorporates D3 dozer track rails. The sealed and lubricated links include a split master link for dependable performance.
Long Life Bonded Track PadsThe track pads contain a special rubber compound in order to provide long life and good traction.
Single Speed Planetary DriveA variable displacement motor drives a single-speed planetary that provides variable speed selection.
Large Ground Contact AreaThe steel track’s ground contact area is 3048 mm (120") long and 356 mm (14") wide. This large footprint provides uniform weight distribution over the length of the track.
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.
Precise Mix DeliveryThe material delivery system provides precise mix delivery with minimal operator monitoring. The left and right conveyors in addition to the left and right augers are controlled independently. The ability to control these four components separately eliminates the need for feeder gates.
Ratio ControlThe ratio of conveyor speed to the maximum auger speed is automatically maintained through the controller when changing paving speed. This ratio control feature is helpful when paving wider or thicker on one side of the screed.
Outboard-Mounted Conveyor DrivesThe conveyors have outboard-mounted motors, reducers and drive chains that maximize the tunnel area and reduce segregation.
Gateless SystemThe gateless conveyors run full of mix regardless of the auger speed. When changes in conveyor speed are required, delivery of mix to the augers is immediate. By not always having to run the conveyors at full speed, component wear is significantly reduced. Running at slower speeds can also help reduce the opportunity for segregation, especially when working with larger stone mixes that have a tendency to segregate.
Independent Auger DriveThe auger drive assembly is independent of the tractor, which allows the distance between the two conveyors to be significantly reduced. Keeping the conveyors close together allows the material to flow together more easily as it discharges into the auger cavity. The tunnel and auger design eliminates voids under the chain case in order to minimize segregation.
Adjustable Auger RangeThe auger assembly is hydraulically adjustable with a range up to 215 mm (8.5"). The ability to adjust the auger assembly simplifies loading and unloading from a transport vehicle. Also, when working with larger stone mixes, the augers can be adjusted to allow the mix to flow unrestricted under the auger assembly.
Generator System Provides Quiet Power
The high capacity generator provides power for the electric screed heat, auxiliary lights and job site tools.
Industrial, Single-Phase A.C. GeneratorThe tractor-mounted generator provides 25 kW of power at 60 Hz for the electric screed heat and the auxiliary power panel. Circuit breaker protection, internal electronic voltage regulation and a dual bearing design provide reliability.
Choices Available (Belt or Hydraulic Driven):The belt-driven generator provides full power with a variable frequency when the engine speed increases above 1275 rpm. The hydraulic-driven generator provides full power with a fixed frequency of 60 Hz when the engine speed increases above 1275 rpm.
Optional Auxiliary Power PanelThe power panel provides 8 kW of power for auxiliary lighting and job site work tools. The panel includes four 120 V and two 240 V receptacles.

AS2252C Vers-A-Mat™ ScreedThe AS2252C vibratory screed features narrow front-mounted extenders. The extenders utilize 229 mm (9") wide screed plates making it a perfect fit for commercial applications by reducing the need for handwork when changing paving widths. The main screed plate is 457 mm (18") wide (measured front to back).
AS3251C Extend-A-Mat™ ScreedThe AS3251C vibratory screed features hydraulically-driven, rear-mounted extenders. Heavy-duty support tubes stabilize the extenders providing even material flow for high quality results on highways and streets as well as commercial applications.
