471-20 General DIG-R-TACH Series Hydraulic Attachment Hole Digger

The 471-20 DIG-R-TACH Hydraulic Attachment Hole Digger delivers raw digging power with luxury-level ease. With a massive 731 ft. lbs. of max torque and a low-speed, high-torque motor, this machine eats through tough ground like it's nothing. Built to mount on compact tractor backhoes, mini excavators, and similar machines, this hydraulic digger lets you take on serious jobs with precision and power, while enjoying the ride. Compatible with 2-inch hex hub augers up to 36 inches in diameter, it's built for operators who demand heavy-duty performance without heavy-duty effort.

FEATURES

• FLOW: 7.0–12.0 GPM (26.5-45.4 LIT/MIN): Matches perfectly with higher-output compact machines, giving you smooth, responsive performance across various hydraulic systems. Ideal for operators who need consistent power and digging speed.
• PRESSURE RANGE: 1500-3000 PSI: Engineered to operate at high pressure for maximum torque delivery. This broad range ensures reliable performance in both standard and demanding applications.
• 731 FT. LBS MAX DRILLING TORQUE @ 3000 PSI: Exceptional torque output to power through clay, rock, roots, and other harsh ground conditions. Digs cleaner and faster with less operator input—perfect for large-diameter augers.
• 2 INCH HEXAGON AUGER DRIVE CONNECTION: Built to handle augers up to 36 inches in diameter. Provides a solid, secure fit for high-torque applications without slippage or wear.
• LOW-SPEED, HIGH-TORQUE MOTOR: Offers smooth, controlled power with maximum torque at lower speeds. Ideal for precision digging where power and finesse are equally important.
• DEBRIS/FOREIGN OBJECT PROTECTION GUARD: Shields hydraulic connections from damage caused by flying debris or rough handling. Keeps your machine running longer with fewer interruptions.
• DIRECT-DRIVE CONFIGURATION: Transfers hydraulic power directly to the auger with minimal loss. Improves efficiency, reduces complexity, and ensures long-term durability.
• UNIVERSAL JOINT SWIVEL: Maintains vertical auger alignment throughout the dig. Reduces stress on your equipment and results in straighter, more accurate holes.
• INCLUDES AUGER BOLT: Ready to go right out of the box—includes secure connection hardware for fast and easy setup.
• WEIGHT: 81.6 lbs (37.01 kg): Lightweight enough for compact equipment, but tough enough to handle big jobs. Easily manageable without sacrificing durability or performance.
