Benefits
Up To 10% Less Fuel Consumption
More fuel efficient with standard eco-mode and automatic engine idle shutdown.
Simple Operation
With easy-to-use dials and bright colored LCD screen.
More Productivity
More productivity with optional Intelligent Compaction technologies and flexible vibratory systems.
Features At A Glance
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Make timely, fact-based decisions to maximize efficiency, improve productivity, and lower owning and operating costs.
- Easily track location, machine hours, fuel usage, and idle time.
- Diagnostic codes are made available through online web applications.
- Remote flash works around your schedule to ensure your machine’s software is up to date for optimal performance
