The Ammann ARX 40-2 Tandem Roller makes it even easier for operators to work next to obstructions such as curbs.

The roller, with a drum width of 1300 mm (51.2 in), features a new articulating joint that enables quick drum adjustment from in-line to off-set configurations. Rollers that are offset are able to work close to obstructions. Operators need watch only one drum, knowing the second will be a safe distance from the obstruction. The in-line setting, which enables equal distribution of compaction forces, is preferred on more open jobsites.

The adjustment between in-line and offset configurations is done manually and is easy for operators to make. The articulating joint, which makes the in-line/off-set adjustment possible, is maintenance-free.

The roller features Kubota engines that meet US Tier 4 Final emissions standards and are EU Stage V, and EU Stage IIIA/US EPA Tier 4 interim. It includes an intuitive dashboard layout, a redesign of the front and rear of the machine and a new LED light system. Reduced sound levels improve operator safety, as does the new light system and a new dashboard guardrail.
