ARX 12 TIER 4i

  • Photos

The Ammann ARX 12 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. Double-drive and double-vibration are standard and help deliver optimum compaction results.

An electric 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.
