Description
This high flow auger drive package pairs the Digga 4DDS with hoses, flush-face disconnects and a mount for a skid steer, mini excavator or backhoe. The 4DDS is the crossover model in Digga’s range: it is a high-flow drive that still runs a 2" hex output shaft, so it takes the same A4 and RC4 bits as the standard-flow drives while drilling to a larger maximum diameter than any of them. Above the 4DDS the range moves to 2.5" hex and a different auger family.

| Machine Type | Carrier weight range (Digga) | Mount packages offered |
|---|---|---|
| Backhoe | — | Backhoe Mount |
| Mini Excavator | 3-5T (6,600-11,000 lbs) | Double Pin Mount, Single Pin Mount |
| Skid Steer | 2.5-3.8T (5,500-8,400 lbs) | Extension Frame (TPE) Package, Universal Quick Attach Frame Package |
Across all 10 configurations above, the 4DDS drive itself does not change — only the mount does. Where a carrier weight range shows a dash, Digga publishes no figure for the 4DDS in that class, so the mount is what decides fitment.
| Mount Package | Fits | What it is |
|---|---|---|
| Backhoe Mount | Backhoe | Backhoe cradle mount with linkage and pin, for the dipper of a backhoe loader. |
| Double Pin Mount | Mini Excavator | Two-pin excavator mount with linkage — the usual arrangement on a standard dipper. |
| Extension Frame (TPE) Package | Skid Steer | Telescopic piling and drilling extension frame, for reach and depth beyond a fixed frame. |
| Single Pin Mount | Mini Excavator | Pins direct to a single-pin dipper. Pin diameter and spacing must match your machine. |
| Universal Quick Attach Frame Package | Skid Steer | SSQA frame with linkage and cradle, giving side-shift capability on a full-size loader. |
Every 4DDS configuration can be ordered with the HALO Auger Alignment System. HALO sits in the hood of the drive and shows green when the auger is plumb and red when it is not, so the operator can correct without a spotter — worth adding on fence lines, structural piers and anywhere an out-of-plumb hole means rework or extra concrete. Select Include HALO Auger Alignment System to have it factory-fitted, or No HALO for the standard drive.
The 4DDS package lists the Machine Type first: pick the one that matches your carrier, then the Mount Package that goes with it. Mounts are machine-specific and do not interchange between classes.
Those are the common quick-attach loaders; pin-on and bucket-mount configurations are matched by dimension rather than brand. Add your machine make and model at checkout and we confirm the mount fits before the order ships.
High flow — but unusually it keeps the 2" hex output shaft used by the standard-flow drives. That means high-flow performance without replacing your A4 and RC4 auger bits, which is the main reason to pick it over a 5DDS.
Match it to your machine class. Pin-on mounts — single pin and double pin — are for excavators; quick attach frames and TPE extension frames are for skid steers; the mini quick attach and Bobcat MT mounts are for compact utility loaders; bucket and slide frame mounts suit tractor loaders; and the backhoe mount fits a backhoe dipper. They are machine-specific and do not swap between classes.
The drive unit, hydraulic hoses, flush-face quick disconnects and the mount package you select. Auger bits and extensions are separate — the drive takes any Digga bit matching its output shaft.
HALO is Digga’s LED auger alignment system, built into the hood of the drive. Green means the auger is plumb, red means it is not, so the operator corrects without a spotter. It earns its cost on fence lines, structural piers and any high-volume drilling where an out-of-plumb hole means rework or extra concrete.
No. The 4DDS is a single-speed drive running on a standard two-line auxiliary circuit. Only Digga’s two-speed DDT drives need a case drain.
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.
Check three things: and it needs 10-36 GPM. Add your machine make and model at checkout and we confirm the fit before the order ships.
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.
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.
People reach this listing looking for a skid steer auger attachment, an auger drive with mount, or simply a skid steer auger for a machine they already own. Because the 4DDS configures across several machine classes from one page, it also comes up when someone is comparing a mini excavator auger against a backhoe auger. Every configuration is genuine digga auger equipment built in Dyersville, Iowa.
