The Ammann ARX 20 T4f Tandem Roller is a light, articulated ride-on roller that delivers optimum compaction results through its double-drive and double-vibration systems. The compactor meets Tier 4 Final emissions standards.

The roller works flush against curbs and other obstructions to eliminate the need for special edge compaction efforts. Excellent visibility to the drums also helps the operator.

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.

The ARX 20 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.
