  • Virtual Tour

The Ammann ARX 20-2 is a light, articulated ride-on roller that works flush against curbs and other obstructions to eliminate the need for special edge compaction efforts.

Operators of all experience levels find the machine easy to control, in part because of the automated intelligent functions (such as Automatic Vibration Control (AVC), integrated parking brake, soft/hard mode).

Soft drive enables smooth, steady adjustments to directional changes – particularly important when working on asphalt. Hard drive responds quickly to directional changes.

Durable, maintenance-free components and the fuel-efficient engine maximise uptime and lower lifetime operating costs.

Biofuel Use

Ammann diesel-burning machines are able to utilise hydrotreated vegetable oil (HVO), a biofuel made from waste that reduces CO2 emissions by up to 90%.
