ARX 12 TIER 4f

  • Photos

The Ammann ARX 12 T4f Tandem Roller is a light, articulated ride-on roller that works flush against curbs and other obstructions and eliminates the need for special edge compaction efforts. It meets Tier 4 Final emissions standards.

Double-drive and double-vibration are standard and help deliver optimum compaction results. An electronic drive lever makes for smooth starting and stopping and is among the reasons the roller is popular with operators. Other operator benefits include a rubber-mounted platform that limits vibration and an intuitive instrument panel to help make even an inexperienced operator successful.

The ARX 12 is built with high quality, long-lasting components that reduce the cost of ownership over the lifetime of the machine. It is reliable, economical, safe and fuel efficient.
