7DDT 2 Speed High Flow Skid Steer Auger Package with Mount - Digga

Overview

The 7DDT is the largest two-speed high flow skid steer auger attachment Digga builds on a 2.5 inch hex shaft: 6,308 ft-lbs, 48 inches in earth, and the shift that makes large-diameter production drilling practical on a loader. On this page it comes three ways: Drive Only if you already have a frame, on the Universal Quick Attach Frame Package with 7 ft hoses and flush-face disconnects, or on the Extension Frame (TPE) Package, Digga's telescopic piling and drilling extension.

Key Features of the Digga 7DDT 2 Speed Skid Steer Auger Package

• Torque 6,308 ft-lbs at 3,000 PSI and 7,344 ft-lbs at 3,500 PSI, as published by Digga for the 7DDT
• Recommended flow 10-36 GPM, with 10 GPM the floor for rated torque
• 2.5 inch hex output shaft taking A6 earth auger bits, RC6 rock and earth combo bits and DR6 dedicated rock augers
• Drills to 48 inches in earth and 30 inches in clay or shale, subject to ground conditions
• Digga gearbox with an integrated pressure relief valve, so no external valve block and fewer joints to leak
• The gearbox follows the bit down the hole, so drive height is not lost from drilling depth
• HALO Alignment Kit optional — HALO built into the drive hood at the factory, reading plumb to ±0.25 degrees per Digga
• Shifts between high torque and high speed under load, without stopping or lifting out
• Case drain hose included; the machine needs the low-pressure return line
• 10 ft powerlead with a 2-pin connector fitted for the shift solenoid
• 5 year gearbox and 3 year motor warranty for drilling use, plus lifetime shaft pull-out cover

Figures as published by Digga for the 7DDT. Maximum drilling diameter depends on ground conditions and is a guide rather than a rating.

Choosing How the 7DDT Mounts

The TPE is engineered for drives up to 16,000 ft-lbs, so the 7DDT sits well inside it. One thing to plan for: a drive working 12-14 ft down needs more hose than the 7 ft set, and Digga's TPE hose kits come in 14 ft and 16 ft for exactly that. Tell us if the package is for TPE work and we will confirm hose length with the order.

HALO Alignment Kit

Every 7DDT on this page — both frame options and Drive Only — can be taken with No HALO or with the HALO Alignment Kit. Despite the name it is not a bolt-on: choosing it supplies the 7DDT with HALO built into the drive hood at the factory, with the extension cable and in-cab 12V plug. A ring of green lights means plumb; red and green guide the operator back when the drive drifts. On a one-person crew it replaces the spotter at the hole.

What Comes in the 7DDT Skid Steer Package

• Digga 7DDT auger drive
• Universal skid steer frame and 75mm linkage, or the TPE extension frame, unless you choose Drive Only
• 7 ft hoses with flush-face quick disconnects on the frame package
• Case drain hose, required on every two-speed drive
• 10 ft powerlead with a 2-pin connector for the shift solenoid
• HALO where the HALO Alignment Kit is selected
• Not included: auger bits, and the Plug N Play Controller Kit needed to shift the drive from the cab

Where the 7DDT Sits in Digga's High Flow Range

Against the 6DDT, the 7DDT adds 26 percent more turning force, from the same minimum flow. Nothing larger is offered on the 2.5 inch hex shaft — above the 7DDT, Digga moves to the 9K drives and a bigger machine class. The 7DDS is the single-speed version of the same size at 6,164 ft-lbs, without the shift, the case drain or the controller, and for considerably less. Max speed is 80 RPM, against 54 on the 7DDS.

Which Loaders Fit the 7DDT?

The 7DDT package mounts on the universal skid steer quick attach plate, so fitment is decided by hydraulics rather than brand. The 7DDT needs a high flow auxiliary circuit and at least 10 GPM to reach the torque above.
