Digga PD25-7 Auger Drive Package for 20–28 Ton Excavators – 100mm Square Shaft
Premium High Torque Auger Drive Package for Foundation Drilling, Screw Piling & Civil Construction
The Digga PD25-7 Auger Drive Package is engineered for demanding drilling applications including foundation boring, screw piling, utility installation, pole foundations, civil construction and large-scale earthmoving projects.
Designed for excavators in the 20–28 tonne class operating between 120–230 litres per minute, the PD25-7 combines Digga's proven planetary gearbox technology with the Digga Danfoss Bell Motor to deliver exceptional torque, reliability and drilling performance in demanding ground conditions.
The PD25-7 comes standard with Digga's HALO Alignment System, helping operators drill straighter holes faster while reducing wear on augers, drives and machine components.
Manufactured in Australia and built for professional contractors, piling specialists, civil contractors, government departments, utilities, construction companies and hire fleets.
Fitment & Attachment Class Information
Excavator tonnage is a guide only.
Attachment build class, compatibility and pricing are determined by the machine's pickup configuration, including:
- Pin diameter
- Pin centres
- Width between ears
- Quick hitch configuration
Machines with larger pin sizes require heavier-duty attachment construction with increased material thickness and reinforcement, even where machine tonnage may overlap other classes.
This ensures correct fitment, structural integrity, durability and long-term performance.
Some machines may vary from standard specifications depending on hitch setup and manufacturer configuration.
