  • Compacts granular and moderately cohesive soils.
  • Compacts soil in trenches, foundations, and on slopes.


  • In suitably granular soil, GenPac Compactors can readily double as pile driver.
  • GenPac offers a faster, less-expensive technique for driving wood, steel, vynil and aluminum sheeting, H and I beams, piling, posts and sea walls. The GenPac sends vibration along the length of the item being driven, breaking the skin friction that slows driving.
  • This vibration, coupled with the impulse force of the GenPac and the carrier’s down pressure, makes the unit a truly remarkable driver of beams, sea walls and piling.


  • Designed to fit all carriers 4,000 lbs to 18,000 lbs.
  • Capable of producing a Mod Proctor Density of 95% or better.


  • Baseplate and eccentric housing are integrally mounted; no bolts to tighten.
  • Heavy rubber isolators prevent vibrations from reaching the carrier boom.
  • Fast, easy installation - complete mounting kits allow simple matching of hydraulic attachment to the carrier. Install the GenPac in place of the bucket - ready in minutes.

Works well

By Roger B. (Kent, United States) on 21 May 2019

I use mine for pounding trellis post in apple orchard. Had to modify it for a Kubota 036 excavator. Love the thing.
