Overview
The largest single-speed excavator auger drive Digga builds, the 30DDS sits at the top of the DDS range, at the top of the 18–30 tonne class on the 100mm square shaft. Above it, Digga’s range moves to the SD “Supa” drives, which are a different class of machine entirely — radial piston motors, far higher torque, and a purpose-built anchoring capability. The 30DDS is the most drive available before that step.
Key Features of the 30DDS High Flow Auger Drive
- 30,712 ft-lbs of torque — the figure Digga publishes for the 30DDS
- 26-60 GPM recommended flow — match this against your carrier’s auxiliary circuit
- 4" Square output shaft — sets which Digga auger bits fit
- Compact high torque Digga manufactured gearbox
- Digga designed Eaton motor with integrated pressure relief valve eliminating 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
- 5 year gear box and 3 year motor warranty / lifetime shaft pull-out warranty
- Over 40 years design and manufacturing experience
- Easily converted to a Screw Anchor Drive with the addition of our patented ‘Anti Kickback Valve’
- TRU-CUT – a 12†auger cuts a 12†hole, no more oversized holes!
Why This Drive Suits Its Machine Class
- It is the top of the conventional range — the next step up is the SD Supa series, which is a different product class with different pressures, mounts and warranty terms.
- Highest torque available without the complexity of a two-speed or a Supa drive — standard two-line hydraulics, no case drain, no electrical control.
- Shares augers, extensions and mounts with the 20DDS and 25DDS.
- Built for large-diameter piling on the biggest excavators this range serves.

Which Machines Fit the 30DDS?
For 18–30 tonne excavators at the top of the class, pin-mounted with a 100mm linkage:
| Fitment factor | Requirement |
|---|---|
| Mount | Excavator pin mount and linkage, sold separately, selected by pin diameter |
| Case drain | Not required — this is a single-speed drive |
| Hoses | Sold separately |
| Auger bits | Sold separately |

30DDS High Flow Auger Drive Questions, Answered
What comes after the 30DDS?
The SD “Supa” anchor and drilling drives. Those use radial piston motors, operate at far higher torque, and are built specifically for screw anchor and pile installation. They are a different class rather than simply a bigger version.
Is the 30DDS suitable for screw anchoring?
Digga’s warranty terms treat anchoring separately from drilling. Anchoring above 12,000 ft-lbs without an Energy Control Valve carries no warranty at all, so the SD series with ECV is the correct tool for anchor work.
Does the 30DDS require a case drain?
No. The 30DDS is single speed and runs on a standard two-line auxiliary circuit. Digga’s two-speed DDT drives are the models that need one.
What warranty applies to the 30DDS?
Five years on the gearbox, three years on the motor, and a lifetime shaft pull-out warranty for drilling use, subject to maintenance per the operator’s manual. Digga’s terms treat anchoring separately — drives used for anchoring above 12,000 ft-lbs without an Energy Control Valve carry no warranty.
Can the 30DDS install screw anchors?
Digga distinguishes drilling from anchoring. Anchoring above 12,000 ft-lbs without an Energy Control Valve voids cover entirely, so an ECV-equipped anchor drive is the right tool for that work rather than a drilling drive.
What hydraulic flow does it need?
This one is rated for 26-60 GPM. Check that figure against your machine’s auxiliary hydraulic output before choosing — a machine that cannot supply the rated flow will never reach the rated performance, and one that exceeds the limit will run the attachment hot.
Will this fit my machine?
Check three things: it is built for 18-30T (39,700-66,100 lbs); the interface is Excavator pin mount and linkage, sold separately, selected by pin diameter; and it needs 26-60 GPM. Add your machine make and model at checkout and we confirm the fit before the order ships.
How is shipping calculated?
Shipping is calculated at checkout — add the item to your cart, enter your delivery address, and the shipping charge is shown before you complete your order. Lift gate service is available for residential deliveries and can be selected at checkout.
How do I order?
Add the item to your cart and check out online — the order page asks for your machine make and model, so there is no need to call ahead. We check the mount against your machine after the order and come back to you if anything needs changing. If you would rather ask first, email support@eskidsteer.com or use the chat button on your screen.
What to Order Alongside the 30DDS
- Auger bits — The 30DDS takes a 4" Square output shaft, and the shaft size decides which Digga bit family fits.
- Mount and linkage — the 30DDS ships without one, so the interface is chosen to match your carrier rather than a generic plate.
- Hydraulic hoses and flush-face quick disconnects — sized to the 30DDS’s 26-60 GPM flow rather than to whatever is on the shelf.
- XO40 and XT40 auger extensions — cheaper than buying a longer bit for the occasional deep hole on the 30DDS, and they stack.
Contractors reach this page searching for a excavator auger, for a auger drive, or specifically for a 100mm square shaft. The 30DDS also comes up when people are comparing an high flow auger drive against a digga auger, since Digga builds both on shared mounts and shared auger families. Whichever term brought you here, the 30DDS and every other 30dds auger drive drive in the range is made in Dyersville, Iowa.
