Four Auger Sizes
Caterpillar offers four auger models: the direct-drive A7 Auger for the Mini Hydraulic Excavator, the chain-driven A14B Auger for the Mini Hydraulic Excavator, Multi Terrain Loader and the Skid Steer Loader, the planetary-driven A19B Auger for the Mini Hydraulic Excavator, Multi Terrain Loader and the Skid Steer Loader and the planetary-driven high flow A26B Auger for the Skid Steer Loader.

A7 Auger
Direct-drive design and hex-shaped output shaft. Compact cylindrical housing design is enclosed to minimize contaminants entering the drive housing when operating.

A14B Auger
The A14B direct drive system features a variable speed, bidirectional, gerotor style hydraulic motor coupled to a sprocket/chain reduction system for optimal bit speed and output torque for light to moderate duty applications.

A19 Auger
The A19 single reduction planetary system features a variable speed, bidirectional, gerotor style hydraulic motor mounted to an in-line planetary gear box for optimal bit speed and output torque for moderate to heavy duty applications. The additional output torque provides better performance with larger diameter bits.

A26B Auger
The A26B double reduction planetary system features a variable speed, bidirectional, gear hydraulic motor mounted to a planetary gear box for optimal bit speed and torque for extreme duty, high performance drilling requirements. Its exceptional output torque capabilities provides excellent performance in the toughest conditions withe the largest diameter bits.

Wide Range of Auger Bits
Auger bits are rugged and adaptable to a wide range of projects. Standard and tree bit options are available in a variety of diameters. Hex-to-round shaft adapter is available to accommodate existing round auger bit mountings.
