Cat C7.1 Engine

The C7.1 engine provides 168 kW (225 hp) and meets U.S. EPA Tier 4 Final and EU Stage IV emmision standards.

Quiet Heating

Quiet heat mode operates at an engine speed of 1300 rpm and provides screed plate heating in under 15 minutes.

Better Visibility, Exceptional Comfort

The dual independent operating stations can extend beyond the frame for good all-around visibility. The low profile, front-mounted cooling system improves forward viewing and the redesigned auger assembly optimizes visibility to material height in front of the screed. The heated seat option, multiple seat adjustments, and tilting consoles conform to the operator to provide day-long comfort. The top-mounted cooling system directs fumes, hot air, and fan noise away from the crew for a cooler and quieter working environment.

Single Touch Operation

Single touch features for the auto-fill feeder system, feeder system activation, and hopper control, allow operators to concentrate on truck exchanges and other duties for improved efficiency.

Auto-Fill Feeder System

The auto fill feeder system simplifies starts by alternating the conveyors and augers until the mix height reaches the sensor set point, eliminating manual activation and constant monitoring.


The Mobil-Trac undercarriage minimizes tow-point movement. The front and rear bogie sets crawl over obstacles and help maintain ground contact. The smooth belt option performs well on soft base materials and fresh mats. The tread-bar design excels on loose paving/transport conditions.

Screed Heat Technology

Exclusive zone monitoring allows heating to continue in the event of a temperature sensor failure. The system also monitors heating elements for failure conditions, eliminating unnecessary replacement.

Screed Display

Easy Operation

F-Series pavers allow Cat Grade Control to be operated from any of the two tractor or two screed consoles. Split screen mode can be setup to monitor each side of the screed allowing single person operation.


  • Eco-mode

    Eco-mode utilizes an engine speed of 1650 rpm and reduces fuel burn by up to 5% over Cat E-series pavers while also lowering sound levels even more.

  • Automatic Engine Speed Control

    When automatic engine speed control is activated, the engine speed is reduced to an idle speed of 1000 rpm when the propel lever is moved to neutral or to 1300 rpm when screed heat is active.

  • Advanced Eco-mode

    Eco-mode and automatic engine speed control when activated together modify the engine rpm based on load factors. When activated the engine will operate at 1650 rpm when paving. If the upper power threshold is exceeded, the engine speed will increase to 2200 rpm and remain there until the demand drops below the threshold and remains there for 30 seconds, ensuring reliable performance.

  • Quick Heating

    Quick heating mode provides a heat-up time in under 35 minutes when equipped with the 10 m (33 ft) wide-width paving package.

  • Temperature Ranges

    Three preset heating options provide a wide range of temperatures for various mix designs; Low is 110 degrees C or 230 degrees F, medium is 130 degrees C or 266 degrees F, high is 160 degrees C or 320 degrees F.

  • Fumes Management

    The exclusive 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.

  • Simple Technology

    Technology helps operators perform. Intuitive symbols and large graphics simplify operation, while the interactive LCD display with touchscreen access to generator activation, screed temperature control, and mix height adjustment, increase efficiency.

  • Single Touch Feeder System

    The two augers and two conveyors can be activated automatically with a single button, simplifying setup. Each auger and each conveyor can still be operated independently when needed.

  • One Touch Hopper Control

    The hopper wings and hydraulic apron can be folded with a single touch and release. The system can be tailored to activate left or right wings, or the front hydraulic apron independently or together.

  • Cleanout and Warm-Up Mode

    This feature activates the augers, conveyors, and tamper-bar (if equipped) at a reduced speed, allowing the application of release agents to prevent material build-up.

  • Mix Height Adjustment

    Mix height adjustment in front of the screed can be modified from the tractor LCD display for increased versatility when needed.

  • Hydraulic Mainframe Extensions

    The optional 457 mm (18") hydraulic mainframe extensions attach to the auger assembly and provide smooth material flow out to the extenders. They retract with the screed extensions when reducing paving widths.

  • Multiple Feed Sensor Options

    The feeder system can be tailored to automatically operate with 0, 2, or 4 feeder sensors. When paving with 0 sensors due to a failure, simply set the feeder system to automatic and adjust the mix height setting, no need to cycle the manual switch as previous models required.

  • Easier Service

    Hardware-free bed plates simplifies replacement and bottom side mounting hardware for the chain gaurds eliminates bolt wear and material build-up for easier replacement.

  • Durability

    Self-tensioning accumulators, center guide blocks, and rugged internal belt cables ensure durability. The components are rubber coated in order to shed asphalt and prevent accumulation.

  • Easy Adjustment

    Feeder system ratio adjustment capability from the screed provides versatility. Standard hydraulic adjustment for extender height, slope, and crown, allows for on-the-go adjustment at standard and maximum paving widths.

  • Two-Speed Proportional Extender Control

    Exclusive two-speed proportional extender control offers slower speed for precise control around obstacles and quick reaction when extending paving widths.

  • Simple Replacement

    The heating elements slide out for easy replacement, no need to remove the screed plates. Machined screed frames simplify plate replacement and leveling.

  • Tamper Bar Screed Option

    Tamper bar equipped screeds increase density as it tucks material under the screed plates. Three stroke settings of 2, 4, and 7 mm provide versatility and has a variable tamper speed of 0 to 1800 rpm.

  • Wide-Width Paving Packages

    Exclusive power controls simplify adjustment across the entire 10 m (33 ft 4 in) paving width for better mat texture and quality. An innovative hooking system utilizes extender slope to attach wide-width paving packages, eliminating the need for other lifting devices.

  • Precise Control

    More accurate control maximizes mix utilization and saves money. True averaging with sonic sensors that utilize 5 transducers, 2 readings are discarded and 3 averaged. A 10-point Auto-Calibration eliminates over/under adjustment from a single calibration point. Cross-coupling, slope and elevation are maintained with height adjustments. The true 9 m (30 ft) sonic averaging beam modifies tow point movement by 1/3 of total grade deviation.

  • Highly Reliable

    Water-resistant displays, factory installed components, and consistent routing deliver performance. Sealed components withstand heat, moisture, and vibration, while the built-in temperature sensors provide better reliability than bail-type sensors.
