Wacker Neuson’s new 2.5-ton RD 27 ride-on double drum vibratory rollers, which are powered by a 37.5-horsepower Kubota diesel engine, feature a range of improvements designed to provide easy operation and boost visibility.
A multi-function directional control lever has buttons for all vibration options and water on and off, enabling the operator to control all of the common functions of the machine without the need to remove his hands from the control. An ergonomically designed operator’s station includes an easy-to-read dashboard and control panel, and the display layout has a lighted pictorial including water and fuel levels, high and low vibration, front and rear vibration and water on/off.
The roller’s tapered front frame allows for excellent visibility to the front drum, helping the operator align the drum during compaction as well as monitor water coverage.
Designed for applications that include base and finish asphalt layer as well as granular subbase material compaction, the RD 27 is offered in two drum widths—the 39.4-inch RD 27-100 and the 47.2-inch RD 27-120, which weigh in and 5,470 and 5,950 pounds, respectively.
Both models offer single or dual drum vibration and a choice of high or low compaction force—15,599 and 16,860 pounds of centrifugal force for the RD 27-100, and 15,285 and 20,232 pounds for the RD 27-120. The RD 27 models use hydraulics to adjust high and low force, allowing the machine to maintain peak horsepower in both settings.
Additional features include tool free access to the water pump, water filter and water bars. No tools are need to flip up the bumpers to access the tie down points, water bars and lights, and all engine maintenance points are easily accessible from one side of the roller.
