The Eterra Excavator Auger Drive is a hydraulic powerhead that bores holes for posts, footings, and fence-line work from an excavator. It comes in three sizes, 2500, 3500, and 4500, that scale torque and bit capacity to the machine's flow. This is the bare drive only; a Universal Excavator Mount is required to run it and is sold separately.

The Eterra Excavator Auger Drive is a hydraulic powerhead that bores holes for posts, footings, and fence-line work from an excavator. It comes in three sizes, 2500, 3500, and 4500, that scale torque and bit capacity to the carrier's hydraulic flow. It ships as the bare drive only: a Universal Excavator Mount is required to run it and is ordered separately.

A planetary drive spreads torque across multiple gears for smoother power transfer, which is what keeps the shaft from pulling out and costing a crew downtime the way it can on lighter drives. A heavy-duty gearbox protects the internal parts from that stress, while a large thrust plate evenly distributes the weight and pressure of digging across the housing. This is built for excavator crews boring holes in ground too tough for a lighter drive to hold up to.

Common Applications

  • Boring footing, deck, and fence-post holes with Eterra auger bits
  • Augering through compacted soil, clay, and rocky ground
  • Setting deck, dock, and sign posts

Selection Notes

  • Three drive sizes match hydraulic flow and torque to the carrier machine; choose by your excavator's flow.
  • This configuration ships as the bare drive; the Universal Excavator Mount is required and priced separately, it is not bundled the way the skid steer version's mount is.
  • The Flip Mounting Frame available on the skid steer version is not offered for this excavator configuration.
  • Hydraulic hoses and couplers are included; auger bits, extensions, and adapters for round or larger hex sizes are ordered separately.
  • Confirm the recommended bit size for your drive size and ground conditions with the supplier before ordering.
