Its reinforced 6.5 mm thick double flighting and welded construction under a strengthened input shaft collar deliver reliability in demanding settings. It’s built for industrial-grade applications, ensuring consistent performance in challenging soils and longer operation runs, making it a staple for landscapers and utility terrain work on larger properties.
Titan Attachments 3 Point Standard PTO-Stump Grinder
The Titan Attachments Standard Series PTO Stump Grinder is compatible with Cat 1, 3-point tractors and offers easy operation by driving the tractor forward to engage the grinder. Its PTO-driven design eliminates the need for hydraulic components, reducing maintenance. A 24″ carbide steel teeth cutting wheel with 34 replaceable shear blades delivers substantial stump removal capability, extending below ground depth to minimize residual stump traces. The model includes a slip-clutch PTO shaft for durability and smooth engagement in fieldwork.
Tool Tuff Model 400 3-Point Digger — 6″ Auger
The Tool Tuff Model 400 3-Point Tractor Post Hole Digger is configured for compact and sub-compact tractors, offering a 6″ auger with a robust gearbox and a PTO driveline. It features multiple adjustment holes and a manual canister for controlled operation. The setup provides practical depth and stability for post-hole and stump-related tasks on smaller tractors, delivering a reliable balance between maneuverability and performance in tight spaces.
Tool Tuff Pole-Star 6″ Compact Auger — 36″ Length
Tool Tuff’s 6″ diameter Compact Auger in a 36″ length serves situations requiring smaller diameter digging with compatibility for standard 2″ round shafts. The product emphasizes replaceable edges, welded steel, and powder-coated protection, along with a dual-bolt connection for secure mounting. It is a practical choice for precision stump work around trees and edging where a smaller auger is advantageous.
Tool Tuff Pole-Star 9″ Compact Auger — 36″ Length
With a 9″ diameter, this Tool Tuff Pole-Star auger is designed for heavier digging tasks while remaining compatible with 2″ round gearbox outputs. It features replaceable edges, welded steel construction, and a powder-coated finish for enhanced durability in challenging soil types. The 36″ length maintains reach while enabling stable operation with a suitable 3-point or hitch-mounted system.
Buying Guide: Key Purchase Considerations
- Drive compatibility: PTO-driven, 3-point hitch, or earth auger drives with a specified torque rating. Confirm your tractor’s output shaft size (2″ round vs 2″ hex) and available PTO rpm.
- Diameter and length: Larger diameters remove more material per stroke but require more torque. Longer augers provide deeper reach but can affect maneuverability on small tractors.
- Flighting and durability: Double or reinforced flighting, 6.5 mm or thicker construction, and replaceable cutting edges extend life in tough soils and prevent frequent replacements.
- Attachment compatibility: Ensure the model matches your gearbox output shaft and three-point mounting system. Some augers are designed for specific drive configurations (hex vs. round shafts).
- Maintenance and replacement parts: Look for replaceable center points, blades, and edges, as well as coating options (powder-coated) to resist corrosion in damp environments.
- Intended use: Separate stump-grinding attachments and hole-digging augers—while related, stump planers and grinders serve different outcomes. Identify whether you need cutting power for stumps or hole-digging capability for posts.
- Safety and mounting: Verify safety shields and quick-release or adjustable mounting positions. Secure mounting reduces wobble and preserves equipment life during operation.
