Compact 36″ Industrial Duty Hex Drive Auger
Designed for tractor-mounted post-hole diggers and skid steers with a 2-inch hex output shaft, this auger is built for professional-grade use. The reinforced 6.5 mm thick double flighting and a strengthened input shaft collar deliver durability under demanding drilling conditions. Its hex-drive output ensures a secure connection and reliable torque transfer, reducing the risk of slipping in tough soils.
Key notes: The unit is specifically compatible with 2″ hex drives and is not suitable for 2″ round drive diggers. Industrial-grade materials emphasize longevity, making this auger a solid choice for frequent post-hole work on construction sites or large landscaping projects.
Hydraulic Post Hole Digger For Skid Steer Tractors (12″ Rock Auger Combo)
This unit offers fully hydraulic operation, compatible with 2″ hex drive earth and rock augers up to 18″ in diameter and works with 12-21 GPM flow skid steers at up to 4000 psi. The hydraulic design provides smooth, controlled digging across varying soil textures, including rocky conditions, with straightforward integration into existing skid steer hydraulics.
Best suited for operators who need flexibility with auger sizes and reliable hydraulic performance without relying on mechanical drive options.
Hydraulic Post Hole Digger For Skid Steer Tractors With 9″ Earth Auger
Fully hydraulic operation supports use with 2″ hex drive earth and rock augers up to 18″ in diameter, compatible with 12-21 GPM flow skid steers and up to 4000 psi. This model emphasizes consistent hydraulic performance for medium to large auger diameters, making it a flexible option for projects requiring frequent diameter adjustments or deeper holes.
Ideal for professionals needing robust hydraulic control and a reliable platform for mid-sized augers in dense soils or layered substrates.
Tool-Tuff 420 Hydraulic Post Hole Digger (12″ Earth Auger)
Fully hydraulic operation supports 2″ hex drive earth and rock augers up to 18″ in diameter, with 12-21 GPM flow skid steers and up to 4000 psi. The 420 series model emphasizes higher flow compatibility and durable construction, making it suitable for demanding digging tasks where large diameters or deeper holes are needed.
This option is advantageous for users who regularly work with larger augers and seek a hydraulic unit designed for intense workloads and rapid cycle times.
Titan Attachments 48in Skeleton Rock Bucket
This rock bucket is designed to fit almost all skid steers, loaders, and tractors via a universal SSQA connection. It features a 0.5-inch grade 50 structural steel shell with reinforced 4 x 4-inch tubular steel support on top for added durability. Replaceable teeth allow for cost-effective maintenance when wear occurs, keeping the attachment productive over time.
Best for material handling and debris sorting while preparing surfaces or clearing rocky debris on site. It complements digging operations by isolating rocks and larger chunks for easier loading or removal.
Titan Attachments Trencher Skid Steer Attachment
This trenching attachment offers 36 inches of depth with a 6-inch-wide rock chain. It uses a universal skid steer quick tach mounting system for quick and easy attachment changes. The chain mechanism is designed to rotate in reverse to expel dirt and rocks, reducing clogging and enhancing trenching efficiency in compact or rocky soils.
Suitable for trenching tasks adjacent to structures or utilities, where controlled, narrow trenches are required, and soil conditions demand efficient debris management and trenching precision.
Buying Guide: Key Purchase Considerations For Skid Steer Rock Augers And Attachments
- Drive compatibility: Determine whether your skid steer uses a hex drive or a round drive system, and verify input shaft size (commonly 2 inches for many post-hole diggers). Mismatches can cause reduced torque transfer or fitment issues.
- Hydraulic vs. mechanical: Hydraulic post hole diggers offer smoother operation and multi-size augers, ideal for large-scale projects and rocky soils. Mechanical (hex drive) tools rely on tractor power and can be simpler for smaller tasks but may limit auger options.
- Auger diameter range: Choose auger diameters that fit your typical hole requirements. Larger diameters remove more material but require more power and may slow drilling in dense soils.
- Flow and pressure requirements: For hydraulic units, ensure the skid steer’s flow rate (GPM) and operating pressure (psi) meet the tool’s specifications to avoid underperformance or overheating.
- Construction and durability: Look for reinforced flighting, thick walls, and robust input collars. For rock environments, hardened steel and corrosion-resistant coatings extend tool life.
- Accessory compatibility: If planning to trench, bucket, or debris-clearing tasks, consider attachments that complement ground preparation and site cleanup, such as skeleton rock buckets and trenchers with universal quick tach compatibility.
- Maintenance and replaceability: Features like replaceable teeth reduce long-term costs and downtime. Check for availability of spare parts and ease of blade or tooth replacement.
- Safety considerations: Use proper shieldings, follow operator manuals, and ensure stable machine setup on uneven or rocky ground. Use trench safety practices when digging near utilities or slopes.
- Cost vs. frequency: For frequent heavy-duty use, investing in industrial-grade, heavy-duty augers and hydraulic diggers can yield better long-term value through durability and performance.
- Manufacturer support: Consider brands with accessible customer service and straightforward warranty policies to minimize downtime in case of wear or a failure.
