OPERATOR COMFORT AND CONTROL

Improved ingress/egress with an improved cab with flip up armrest.
Keep your operators informed about machine conditions and operation with VIMS™ 3G machine monitoring system.
Safety and visibility enhanced with standard rearview camera.
Preferred temperature settings maintained with automatic climate control.

TOP-TIER SERVICE AND SUPPORT

Easier access and in a controlled environment; electronics bay is located inside the cab.
Focused on safety with ground level or platform access to most major components.
Ground level: emergency shutdown, battery disconnect, and jump start.
Quick visual inspection and minimize fluid contamination with sight gauges for coolant, transmission, and hydraulic oil.

POWERFUL EFFICIENCY

Powerful, responsive Cat® 7.1 engine is designed for maximum fuel economy and increased power density.
Reliable performance and low emissions.
High productivity with optional four-way tilting blade.
Two engine options available that meet U.S. EPA Tier 4 Final and EU Stage V emission standards or U.S. EPA Tier 3 and EU Stage IIIA equivalent.

PRODUCTIVITY WITH TECHNOLOGY

Optional Cat Compact 3D mapping technology combines advanced compaction measurement, in-cab guidance, and reporting capabilities to help you consistently meet compaction targets fast, uniformly, and in fewer passes – saving on fuel and the cost of unnecessary rework.
Cat Compaction Control with Machine Drive Power (MDP) is an energy-based measurement system that correlates compaction with rolling resistance to provide an indication of soil stiffness.

OPTIMIZE COMPACTION

Chevron tamping tip design provides greater ground pressure, more compaction, excellent traction, and a smooth ride.
Symmetrical tamping tip pattern results in equal compaction in forward or reverse. Tips are full perimeter and replaceable. The tip is welded to a base assembly, then welded directly to the drum.

OPERATOR COMFORT AND CONTROL

Improved ingress/egress with an improved cab with flip up armrest.
Keep your operators informed about machine conditions and operation with VIMS™ 3G machine monitoring system.
Safety and visibility enhanced with standard rearview camera.
Preferred temperature settings maintained with automatic climate control.
Premium plus seat with leather finish containing forced air heating and cooling, two-way thigh adjustment, power lumbar and back bolster adjustment, and dynamic end dampening.

POWERFUL EFFICIENCY

Powerful, responsive Cat® 7.1 engine is designed for maximum fuel economy and increased power density.
Reliable performance and low emissions.
High productivity with optional four-way tilting blade.
Two engine options available that meet U.S. EPA Tier 4 Final and EU Stage V emission standards or U.S. EPA Tier 3 and EU Stage IIIA equivalent.
For the Tier 4 Final and Stage V option, the Cat Clean Emissions Module contains a diesel oxidation catalyst, diesel particulate filter, and Cat Regeneration System, utilizing SCR technology.
Regeneration is completely automatic and does not interrupt the machine’s work cycle.
Experience maximum responsiveness and control with Steering and Transmission Integrated Control System (STIC™).
Conserve more fuel with the automatic engine and electrical system shutdown.
Achieve greater momentum on grades and fuel savings by carrying that momentum through the shift points with the all new Advanced Productivity Electronic Control System (APECS) transmission controls.
Operators experience less fatigue with throttle lock to maintain engine speed and reduce fuel burn.

PRODUCTIVITY WITH TECHNOLOGY

Optional Cat Compact 3D mapping technology combines advanced compaction measurement, in-cab guidance, and reporting capabilities to help you consistently meet compaction targets fast, uniformly, and in fewer passes – saving on fuel and the cost of unnecessary rework.
Cat Compaction Control with Machine Drive Power (MDP) is an energy-based measurement system that correlates compaction with rolling resistance to provide an indication of soil stiffness.
Link technology (standard) provides access to machine location, hours, fuel consumption, idle time, events, and diagnostic codes through the online VisionLink® interface.

OPTIMIZE COMPACTION

Chevron tamping tip design provides greater ground pressure, more compaction, excellent traction, and a smooth ride.
Symmetrical tamping tip pattern results in equal compaction in forward or reverse. Tips are full perimeter and replaceable. The tip is welded to a base assembly, then welded directly to the drum.
Each wheel has two cleaner bars to keep the drums free of carryover dirt, regardless of rolling direction so efficiency is maximized.
The adjustable cleaner bar tips (standard or abrasive type) are heat-treated and direct-hardened cutting edge steel to increase wear life, which translates into lower operating costs.
