13DDS High Flow Auger Drive - Digga

📘 Overview

The Digga 13DDS is a high-flow single-speed excavator auger drive for 13–16T excavators machines — delivering the torque and flow handling required for large-diameter foundation, pile, and caisson drilling. Built around Digga's compact high-torque planetary gearbox with Digga-designed Eaton motor and integrated pressure relief valve, the 13DDS eliminates bulky external valve blocks. 2-piece shaft design. 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 13DDS | High-flow single-speed excavator auger drive
• For 13–16T excavators class excavators
• Compact high-torque Digga planetary gearbox
• Digga-designed Eaton motor with integrated PRV
• 2-piece shaft design — maximum side load without bearing overload
• HALO alignment system compatible
• Warranty: 5-year gearbox | 3-year motor | Lifetime shaft pull-out
• Made in Dyersville, Iowa, USA | Digga — attachments since 1981

🔑 Benefits

• Purpose-built for 13–16T excavators class machines — not an undersized drive rated-up for a larger machine — using an underpowered drive on a large excavator limits drilling performance to the drive's rated capacity, not the machine's. The 13DDS is engineered specifically for this machine weight class.
• Integrated PRV eliminates the most common excavator drive failure point — external PRV blocks create additional connections and potential leak points. Integrated design reduces leak risk and simplifies installation.
• 5-year gearbox warranty far exceeds the 1-year industry standard — reflects Digga's engineering confidence and manufacturing quality.
• HALO compatibility ensures straight holes in precision foundation work — on large excavator drilling for commercial foundations, hole deviation causes significant rework cost. HALO provides real-time plumb feedback from the cab.
