Digga 4DDS Specifications
Choosing the Mount for Your 4DDS
Pin diameter varies by machine, so enter the make and model with the order and we confirm the mount before it ships. The linkage on this drive is the 75mm size (HI-000393K on excavators) — the 100mm and 130mm linkages belong to larger drives. All three are listed under Auger Drive Mount Linkages.
HALO Alignment Kit
Every 4DDS option on this page can be taken with No HALO or with the HALO Alignment Kit. The kit is not a bolt-on: the drive arrives with HALO built into its hood, with the extension cable and in-cab 12V plug. A ring of green lights means plumb and red guides the operator back — which is what replaces judging plumb from the cab, off to one side of the hole. Retrofitting an older drive is a separate HALO Retrofit Kit.
Where the 4DDS Sits in Digga's Range
Against the 4DSS, the 4DDS adds 9 percent more turning force, from a flow range of 10-30 to 10-36 GPM. The 4DDS is the largest drive on the 2 inch hex shaft. Above it Digga moves to the 5DDS and a 2.5 inch shaft, which means a different bit family. Max speed is 108 RPM. Speed and torque trade against each other, so the smaller drives in this range spin faster and the larger ones pull harder.

Digga 4DDS Excavator Package Questions, Answered
Single pin or double pin for the 4DDS?
A single pin lets the drive hang and find vertical on its own, which suits plumb holes. Two pins fix it to the dipper so the boom sets the angle, which suits angled holes and slopes. Match the pin range to the pins on your dipper.
Do I need to remove my quick coupler?
For a pin mount, yes — it pins where the bucket pins. If you would rather keep the coupler on, Digga makes coupler hitches for TAG, Wain Roy, John Deere, Kubota and Bobcat X-Change couplers, sold separately.
What size holes will the 4DDS drill?
Digga rates it to 40 inches in earth and 24 inches in clay or shale. On a machine at the light end of the class, the practical limit is often set by the machine rather than the drive.
Which bits and extensions fit?
A4 earth auger bits, AB4 bolt-on auger bits and RC4 rock and earth combo bits on the 2 inch hex hub, with 2 inch hex auger extensions if you need to drill deeper than the bit reaches.
Which linkage does it take?
The 75mm size. Digga sets linkage by the drive: 75mm for 1DSS through 7DDT, 100mm for the 9K through 30K drives, 130mm for the SD range.
How is shipping calculated?
Shipping is calculated at checkout from the weight of your order and your delivery address, and the charge is shown before you complete the order.
On delivery: check the package before you sign. Note any damage on the delivery receipt at the time of delivery, photograph it, and email support@eskidsteer.com — a clean signature makes a carrier claim much harder to win.
