Wacker's new RD 12 Series ride-on asphalt rollers, the RD 12-90 and RD 12A-90, have been newly configured to eliminate rear overhang, allowing enhanced visibility and the capability to compact to the edge of the mat. Both machines have an operating weight of 2,490 pounds, use 35.4-inch-wide drums, and produce a centrifugal force of 3,400 pounds at the front drum (the rear drum is static).
