What's included?


Digga 7DDT 2 Speed High Flow Auger Drive Unit
Fitted with Digga-designed Eaton bell motors with an integrated pressure relief valve and input housing, the innovative design allows the gearbox to go down the hole to maximize drilling depth without extensions.

Over 30 years of design and development have perfected this drive unit, enabling maximum performance in a sleek, ergonomic profile.

  • Digga-designed Eaton motor eliminates the need for bulky valve blocks while reducing many potential leak points
  • 2-piece shaft design ensures maximum side load ratings without increasing load on bearings
  • Integrated PRV (Pressure Relief Valve) to prevent damage to internal motor on kickback
  • Compatible with vehicles that put out 10-36 GPM of hydraulic flow at up to 3500 PSI
  • 2.5" Hex Output Shaft matches industry-standard Auger Bits
  • Compact, high-torque Digga-manufactured gearbox generates a whopping 7,357 ft-lbs of Torque

Why Choose a 2-Speed Drive Unit?
Digga's flagship 2-Speed Drive Units give you 2 units in one, allowing you to adjust your configuration depending on your job conditions.

Low Speed - High Torque
Ideal for drilling with large diameter augers or hard fracturable rock
High Speed - Low Torque
Ideal for small diameter augers or softer soils where speed is needed.
Switch to high-speed for added spinoff speed for clearing large diameter augers.

  • Minimize Fuel Consumption. Host machines can be run at a lower RPM on certain drilling jobs to save fuel.
  • Drill More Efficiently. 2-Speed Drives allow you to match your torque profile to the perfect profile for your host machine.
