Simple to Operate, Easy to Learn

  • Large, full-color displays keep the operator informed of machine functions including water and fuel levels, impact spacing, and mat temperature.
  • Innovative hand-wheel steering technology delivers precise control and good forward visibility.
  • Easily activate the vibratory system, water spray system and drum offset with the multi-function propel handle.
  • Machine functions with LED indicators have been independently grouped for simplified control and quick activation.
  • Rotary dials with green light indicators provide a quick visual reference and fingertip feel for quick adjustment to speed control and water spray timers.

Better Fuel Economy

  • Get up to 10% better fuel economy with the Cat  C3.6 engine and standard Eco-mode.
  • The C3.6 engine provides 74.4 kW (100 hp) of power and meets U.S. EPA Tier 4 Final emissions.
  • Unique Eco-mode design modifies engine speed based on load requirements; high amplitude vibration utilizes higher engine speeds, while static rolling conserves fuel and operates at low engine speed with even lower sound levels.

Work Safer with Enhanced Visibility

  • Optional top down, 360  viewing utilizes cameras mounted in each corner of the ROPS for excellent work-zone visibility. This option utilizes a high-definition display mounted to a swivel on the upper left side of the ROPS.
  • Optional fore and aft cameras mounted in the front and rear bumpers provide outstanding visibility when approaching obstacles. The camera view is integrated into the main operating display.
  • Optimize sight lines with 360  seating option; always face the direction of travel.
  • LED Lighting delivers excellent job site illumination while conserving energy.
  • Night-lighting option provides additional illumination to the ROPS, drum edges, and drum surfaces.

Easy Vibratory System Set-up

  • Two-amplitude/two-frequency vibratory system automatically optimizes amplitude and frequency with a single switch for simple thin/thick lift operation.
  • Reach compaction goals with automatic speed control; green indicators help ensure travel speed matches correct impact spacing.
  • Built-in application profiles for thin lift or thick lift applications can be quickly activated through the operating display.
  • Single touch vibratory system profiles for frequency and speed help ensure optimal impact spacing.

Ensure Mat Coverage with Compaction Control

  • Pass-count and Temperature Mapping combines infrared temperature sensors with GPS mapping to keep the operator informed of current asphalt temperatures, machine position, pass-count, and layer coverage.
  • Compaction Meter Value (CMV) utilizes a drum-mounted accelerometer to measure the combined stiffness of the asphalt layer, base layer, and sub-base layer to indicate road structure quality beneath the surface.
  • Machine to Machine communication helps keep rolling patterns in sync by sharing mapped data such as CMV, temperature mapping, and pass count coverage between multiple machines.

Prevent Build-Up, Keep the Drum Surfaces Wet

  • High capacity water tank provides long duration between fills
  • Dual water pumps provide back-up capability and alternate with direction of travel to maximize service life.
  • Triple filtration prevents clogs with filters located at the fill point, water pumps, and spray nozzles.
  • Simple rotary dial provides adjustable spray settings and intermittent modes that help conserve water.
  • Integrated freeze protection kit (optional) provides protection in cold temperatures when machine is not in use.
