Ammann's ARW 65-S walk-behind roller features a new pivoting mechanism. The new S version utilizes a pivoting mechanism that enables movement in all directions – forward, backward, and laterally. The prior version could only move forward and reverse. With the S version, the machine can also be moved to the right and left via the control handle.

The lateral movement is a significant advantage to operations. Body weight is not required to direct the machine, which is often the case with other models. This improvement prevents operator fatigue, eliminates surface irregularities, and provides consistency throughout the shift.

"The lateral control makes operating the machine much easier – and much more precise," said Ralf Brutschin, strategic commercial manager for light equipment at Ammann. "The steering results in increased productivity, efficiency and quality."

A hydraulic drum swivel enables the movement when going forward or backward. The drum swivels 15 degrees to the left and right. The operator controls the direction by simply pressing one of the two buttons on the steering unit.

The drawbar is shorter, which makes the machine even more compact. This improves handling and makes transport easier.

Soil and asphalt compaction in one machine

The ARW 65-S offers both soil and asphalt compaction in one machine – with one acquisition cost. That is still the case with the new version.

The 0.3 millimetre (0.01 inch) high amplitude setting makes the walk-behind roller ideal for compacting soil and substructures. The operator can switch to a lower amplitude of 0.15 millimetre (0.005 inch) which is ideal for compacting asphalt and bitumen. The machine is always ready to work on bituminous surfaces thanks to two scrapers on every drum and a 60-litre (15.8-gallon) water tank with a sprinkler system.

The ARW 65-S retains all the features and benefits of the previous ARW 65 version.

The upgraded roller is available with engines from Hatz, Honda, and Yanmar. An electric starter is standard for all three engines. The height-adjustable handle is designed to prevent unwanted vibration from reaching the operator, providing significant comfort.

The roller offers clearance on both drum sides, allowing compaction work close to curbstones, retaining walls, and other obstacles. No extra time-consuming work on edges and in confined areas is needed.

The roller is built without mechanical fast-wearing parts such as V belts and a clutch, helping reduce maintenance needs. In addition, no special tools are required for daily maintenance work.

The machine utilizes an ergonomic guide handle including the dead man's handle that immediately puts the machine in the neutral position if the operator releases his or her grip. In reverse mode, the roller's speed limit is set to 2.5km/h as a safety regulation. Plus, the hydraulic drive helps ensure variable speed adjustment and smooth starting/braking action. The drive system utilizes individual drive motors in each drum. This enables high traction and gradability.

A sprinkling system helps prevent asphalt from caking on the drums and is integrated into the machine for convenience and to protect the system. The tank is fabricated from anti-corrosive materials and has a large capacity (60 litres/15.8 gallons). The cooling system utilizes cooling fins on the hydraulic tank, helping the machine perform in hot conditions.
