Product & applications
About the hydraulic auger drives
Provide rotary power to a compatible auger through a hydraulic drive unit.
Features & benefits
Square output connection
The series uses 75 mm and 95 mm square output connections on different drive sizes.
Size-specific drilling range
Different drive sizes provide the torque and hole-diameter ranges shown in the specifications; the chosen bit must suit the ground.
Typical applications
- Fence and post installationDrill holes in suitable soil for posts and supports, using the required auger diameter.
- Tree planting and landscapingPrepare planting holes in ground suited to the selected soil auger.
- Construction earth drillingDrill suitable earth holes for construction work within the selected drive and bit limits.

Product questions
Hydraulic Auger Drives questions
Are the auger drive and auger bit separate components?
Yes. The hydraulic drive turns a separate ground-engaging auger bit. Confirm the selected bit, extension and shaft connection for the required drilling task.
Can one bit drill all ground types?
No. Soil and rock require the appropriate cutting teeth and bit geometry for the formation.
How should a drive be selected?
Compare required hole diameter, depth and ground conditions with model-specific torque, hydraulic flow and pressure.
Which connections must match?
The excavator mounting, hydraulic supply and output shaft must match the drive, bit and any extension.
