553 DIG-R-TACH 4750 Series Earth Augers

The 4750 Series Earth Augers are built for those who appreciate the power of a round connection and demand uncompromising performance. Featuring the same rugged design as the 4710 Series, these augers are equipped with a 2.562-inch round auger drive connection and are ready to take on the toughest soil conditions without flinching. From the hardened flighting to the heavy-walled axles and precision-formed boring heads, every component is built to handle serious torque and keep you digging hole after hole with speed, strength, and style.

FEATURES

• 2.562 INCH ROUND AUGER DRIVE CONNECTION: Designed specifically for round hub auger systems. Provides a secure, high-strength connection ideal for heavy-duty use and repeat performance across multiple machines.
• FLIGHTING PITCH MINIMIZES POWER REQUIRED, MAXIMIZES LOOSE SOIL REMOVED: Engineered for efficient digging by reducing resistance and improving soil lift. Keeps holes cleaner with less dirt fallback and helps you get more done in less time.
• HEAVY-GAUGED, STEEL, HELICOID OR SECTIONAL FLIGHTING: Built for strength and resilience in rocky, clay, or compacted soils. Resists wear and bending while delivering consistent performance over years of tough work.
• HEAVY-WALLED, STEEL, AXLE: Reinforced to endure high torque and digging forces without failure. Keeps your auger centered and stable for straighter holes and less wear on your equipment.
• FORMED, STEEL PLATE BORING HEAD: Designed to position teeth precisely for optimal soil breakup and cutting efficiency. Enhances performance and wear life in all soil types, from loose loam to hard-packed dirt.
• WIDE SELECTION OF INTERCHANGEABLE CUTTING TEETH: Allows you to match the auger teeth to the soil for superior cutting and penetration. Improves productivity and ensures cleaner holes with every dig.
• OUTSIDE CUTTING TEETH EXTEND PAST FLIGHTING EDGE: Minimizes direct wear on the flighting and helps extend the life of the auger. Produces smoother holes and increases overall durability.
