1DSS Auger Drive Unit - Digga

📘 Overview

The Digga 1DSS Auger Drive delivers 1,467 ft-lbs of torque at 3,000 PSI (max 1,712 ft-lbs at 3,500 PSI) for Compact skid steer machines (0.75–2.5T (1,600–5,500 lbs)), with a recommended hydraulic flow range of 6–16 GPM. Built around a Digga-manufactured high-torque gearbox and Digga-designed Eaton bell motor with integrated pressure relief valve, the 1DSS eliminates bulky valve blocks and reduces potential leak points. The 2-piece shaft design handles high side loads without transferring load to the bearings. HALO alignment system compatible. Warranty: 5-year gearbox / 3-year motor / lifetime shaft pull-out. Made in Dyersville, Iowa, USA by Digga.

⚙️ Key Features

• Model 1DSS | 1,467 ft-lbs @ 3,000 PSI | Max 1,712 ft-lbs @ 3,500 PSI
• Recommended flow: 6–16 GPM
• Compact Digga-manufactured high-torque gearbox — gearbox descends into hole to maximize drilling depth without extensions
• Digga-designed Eaton bell motor with integrated PRV — no bulky valve blocks, fewer leak points
• 2-piece shaft design — maximum side load ratings without bearing overload
• HALO alignment system compatible — optional LED plumb system for precision hole alignment
• 2" hex output shaft — standard auger bit interface
• For Compact skid steer machines: 0.75–2.5T (1,600–5,500 lbs)
• Warranty: 5-yr gearbox | 3-yr motor | lifetime shaft pull-out | Made in USA

🔑 Benefits

• Gearbox-descends-into-hole design maximizes drilling depth without extensions — conventional auger drive gearboxes sit above the machine boom, limiting effective drilling depth to the bit length minus the drive height. Digga's bell motor design allows the gearbox to follow the bit down into the hole, adding 12–18" of usable depth from the same overall drive length.
• Integrated PRV in Eaton motor eliminates the external valve block that is the most common auger drive leak and failure point — external pressure relief valve blocks add connections, fittings, and potential leak paths. The integrated PRV eliminates these components entirely, reducing the number of hydraulic connections by 4–6 per drive.
• 2-piece shaft transfers torque to the bit without bending the shaft in off-center drilling — single-piece shafts transmit side loads directly into the gearbox bearings when drilling in non-plumb conditions. The 2-piece design uses a separate inner shaft that can deflect slightly without transmitting that deflection load to the upper bearing — significantly extending bearing service life in real-world off-plumb drilling.
• Industry-leading warranty reflects Digga's design confidence — 5-year gearbox and 3-year motor warranties far exceed the 1-year coverage standard in the auger drive market. Lifetime shaft pull-out warranty is unique to Digga.
