471-12 General DIG-R-TACH Series Hydraulic Attachment Hole Digger

The 471-12 DIG-R-TACH Hydraulic Attachment Hole Digger is built to bring industrial-grade digging power to your compact tractor backhoes, mini excavators, and small tractor loaders. Designed for serious soil penetration, this direct-drive beast pumps out a massive 426 ft. lbs. of torque to tear through clay, roots, and rocky ground with ease. With a low-speed, high-torque motor, universal joint swivel, and rugged hydraulic protection, this attachment delivers smooth, efficient power, so you can dig deeper, faster, and more reliably, without breaking a sweat.

FEATURES

• FLOW: 5.0–10.0 GPM (18.9–37.9 LIT/MIN): Compatible with a wide range of hydraulic systems for optimal performance on compact equipment. Ensures consistent power output while offering flexibility across machines.
• PRESSURE RANGE: 1500–3000 PSI: Designed to handle the full spectrum of hydraulic power demands, delivering reliable torque in varied working conditions. This wide range supports both light-duty and high-performance digging.
• 426 FT. LBS MAX DRILLING TORQUE @ 3000 PSI: Delivers brute force for cutting through dense soils, tree roots, and compacted terrain. Makes large-diameter holes with ease and speed, saving time and reducing operator strain.
• 2 INCH HEXAGON AUGER DRIVE CONNECTION: Accepts heavy-duty augers up to 36 inches in diameter. Provides superior strength and grip to prevent slippage and ensure consistent drilling performance.
• UNIVERSAL JOINT SWIVEL: Keeps the auger vertically aligned throughout the dig. Reduces side loading, enhances hole accuracy, and minimizes wear on the equipment.
• LOW-SPEED, HIGH-TORQUE MOTOR: Engineered to produce high-output drilling power without sacrificing control. Perfect for tough soil conditions where precision and muscle are equally critical.
• DEBRIS/FOREIGN OBJECT PROTECTION GUARD: Shields hydraulic connections from damage during operation. Preserves the integrity of your system and reduces costly downtime due to maintenance or repairs.
• DIRECT-DRIVE CONFIGURATION: Maximizes power transfer directly from the hydraulic motor to the auger. Improves efficiency, responsiveness, and overall digging performance.
• WEIGHT: 81.6 lbs (37.01 kg) Lightweight enough for smaller equipment while still delivering professional-grade digging force. Easy to handle, mount, and maneuver on the job.
• INCLUDES AUGER BOLT: Comes ready for immediate attachment with the essential hardware included—no extra trips to the supply house.
