Best Hex Drive Auger For Skid Steers
The Compact 36″ Industrial Duty Hex Drive Auger from AGKNX is designed for heavy workload environments. Its reinforced 6.5 mm thick double flighting and strengthened input shaft collar emphasize durability for professional use on tractor-mounted post-hole diggers and skid steers with 2-inch hex output shafts. While it is built for robustness, its 6″ diameter auger is suitable for footings, fence posts, and similar installations, delivering reliable digging performance in demanding soils.
Hydraulic Post Hole Digger With High Capacity
The Tool-Tuff 420 Hydraulic Post Hole Digger offers fully hydraulic operation for skid steers, enabling consistent performance with 2″ hex drive earth and rock augers up to 18″ in diameter. This model is designed for 12-21 GPM flow skid steers and up to 4000 psi, making it a strong choice for mid-to-large projects requiring heavier auger bits. Its hydraulic efficiency reduces operator effort and improves productivity over manual or less-capable units.
Auger Bit For 3 Point Digger, Heavy Duty Bit
The Titan Attachments auger bit is a 12″ drilling bit designed for use with compatible 3-point post hole diggers. It features a fishtail point and a steel construction aimed at penetrating various soil types. The bolt-on fishtail point helps maintain bit stability during deep drilling, while the included safety cover protects the tip, contributing to safer operation on busy job sites.
Hydraulic 9″ Earth Auger For Skid Steer
The 9″ earth auger from Tool-Tuff provides a compact option with full hydraulic operation for skid steers. Compatible with 2″ hex drive earth and rock augers up to 18″ in diameter, this unit supports 12-21 GPM flow and up to 4000 psi. It is well-suited for projects needing a balance between maneuverability and digging width, such as narrower fence lines or small yard installations.
Gas-Powered 72CC Auger Post Hole Digger Set
The Prowoo 72CC Auger Post Hole Digger combines gas-powered mobility with a versatile bit set, including 4″, 6″, and 12″ options and 2 extension rods. The 72CC engine supports one or two-person operation, making it suitable for a range of landscaping, fencing, and planting tasks. The Ultra Blade System enables bit changes and replacements, while ergonomic grips and throttle control aim to improve handling and precision in challenging soil conditions.
When selecting a post hole digger attachment for a skid steer, consider drive compatibility, auger diameter range, and overall build quality. Higher duty ratings and reinforced flighting reduce wobble and wear in rocky soils, while hydraulic units provide consistent torque for large-diameter drilling. Gas-powered options offer portability without hydraulic plumbing, though they may require more maintenance and fuel management on site.
Buying Guide
Key purchase considerations for skid steer post hole digger attachments include:
- Compatibility: Verify that the attachment’s drive interface matches your skid steer or tractor’s output—2″ hex shafts are common for heavy-duty units, but some models require different connections for 3-point diggers.
- Power and hydraulic requirements: For hydraulic diggers, check flow rate (GPM) and pressure (psi) ratings to ensure your machine can operate the auger efficiently without stalling or overheating.
- Auger diameter range and depth: Smaller jobs may only need 4–6″ bits, while footings and larger posts call for 12″ and deeper. Consider the required drilling depth and available bit variations.
- Durability and materials: Look for reinforced flighting, heavy-wall steel, and sturdy input shafts. Industrial-grade attachments generally resist wear in persistent digging tasks.
- Ease of maintenance: Bolt-on bits and quick-change systems can reduce downtime. Check whether spare bits and parts are readily available from the manufacturer.
- Safety features: Safety covers for tips, shields to prevent debris ejection, and secure mounting hardware help minimize on-site risk during operation.
- Operational considerations: Gas-powered units offer portability but require fuel logistics; hydraulic options depend on your loader’s hydraulics but typically deliver smoother operation and larger diameters.
- Cost of ownership: Factor in initial price, maintenance, bit replacement costs, and potential downtime. A higher upfront investment often yields lower long-term per-hole costs in demanding jobs.
- Soil conditions: Rocky, hard-packed, or clay soils may demand more robust augers with reinforced points and thicker walls, as well as higher torque options.
Across the reviewed options, the AGKNX 36″ hex drive and Tool-Tuff hydraulic diggers stand out for heavy-duty performance and hydraulic control, respectively. Titan Attachments provides a durable bit designed to extend the life of 3-point compatible diggers, while Prowoo offers a versatile, gas-powered alternative with a broad bit set for mixed workloads. For smaller or mid-range projects, the 9″ auger from Tool-Tuff or the 12″ bit from Titan Attachments can provide the balance between size, power, and ease of use.
