Tool Tuff 12″ Industrial Duty Rock Auger
The 12″ Tool Tuff Rock Auger provides a robust hex-drive interface with replaceable carbide bullet teeth and a replaceable rock tip. Built for heavy-duty drilling, it features an industrial-grade design with a 48″ length to reach depth while maintaining control on skid steers. The carbide edges and standard replacement parts ensure long-term serviceability, reducing downtime on tough jobs. This auger is suitable for rocky soils and demanding post-hole tasks where reliability matters most.
Compact 36″ Industrial Duty Hex Drive Auger
This 36″ hex-drive auger is designed for professional skid-steer applications with a 2″ hex output shaft. Its reinforced flighting and sturdy input shaft collar provide enhanced durability for repeated use in demanding digging. The heavy-duty construction focuses on reliability in professional settings, making it a solid choice for contractors and crews who require a long-lasting auger that can handle thicker soils and longer reach. Compatibility targets tractor-mounted diggers and skid steers with 2″ hex connections.
24″ Auger Extension for 2″ Hex Drive
The 24″ auger extension is designed to work with a 2″ hex gearbox drive shaft and attaches to a 2″ hex auger receiver. It is intended for hydraulic-powered skid-steer or bucket-loader mounted post hole diggers, expanding reach and depth in challenging layouts. Note that these extensions are not suited for 3-point post hole diggers, making sure installation aligns with compatible skid-steer configurations and hydraulic systems.
Industrial Duty Earth Auger, 9″ Diameter
The 9″ diameter earth auger by Tool Tuff balances compact size with industrial strength. Its 48″ length supports deep drilling, and replaceable cutting edges reduce maintenance costs over time. The fish-tail tip can help begin holes cleanly, while carbide options extend edge life in tough soil. This auger is suitable for frequent use on skid steers when drilling holes for posts or small-diameter applications where precision and longevity matter.
Hydraulic Post Hole Digger for Skid Steer Tractors
This fully hydraulic post hole digger is designed for skid steer operation and accepts earth and rock augers up to 18″ in diameter. It supports 12-21 GPM flow and up to 4000 psi, offering smooth, versatile digging performance for heavier jobs. The hydraulic drive delivers consistent torque, enabling efficient drilling in varied soil conditions without requiring manual auger changes or gear adjustments.
Buying Guide: Key Purchase Considerations
Choosing the right skid steer auger drive depends on drive type, compatibility, torque, and bit options. Hex-drive models offer straightforward quick-change accessories and strong torque for mid-sized to large augers, ideal for structures and fencing. Hydraulic drives provide smooth control and higher digging force, particularly for larger-diameter bits and deeper holes, but require compatible skid steers and hydraulic systems. Consider shaft size, output compatibility, and the sleeve or collar construction to ensure durability in rocky or dense soils. Replacement parts, carbide edges, and fish-tail tips can extend life in demanding environments.
Soil conditions also matter: sandy soils demand different flighting and bit geometry than clay or rocky ground. If you expect frequent bit changes or replacements, prioritize models with standard carbide edges and readily available spares. For contractors needing reach, a longer auger with reinforced flighting reduces wobble and improves hole accuracy. Finally, evaluate maintenance requirements, warranty terms, and the ease of adapter compatibility with existing skid-steer brands to minimize downtime and ensure reliable operation across varied jobs.
