Vibratory Double Drum Rollers

RD 7H-ES / RD 7H-S

WACKER's multipurpose rollers for excellent productivity

These walk-behind, double drum vibratory rollers are capable of performing a wide range of soil and asphalt compaction applications.The exclusive compact design allows for tight side clearance on both sides of the roller. Plus the totally hydrostatic drive eliminates mechanical components providing for less maintenance and greater reliability.



  • Dual smooth drums with bevelededges compact asphalt and granular materials equally as well for added job versatility.
  • Roller features a low oil shutdown for maximum engine protection.
  • Guide handle folds for compact storage, and features excellent shock mounting for low vibration to operator.
  • Large rubber shock mounts absorb vibration and shock to the upperr components, reducing equipment wear and operator fatigue.
  • Special clutch/pump drive system makes possible and easy starting during cold weather as well as a start up under low load.
