MechMaxx SG24 Heavy Duty Stump Grinder
The SG24 model is a PTO-powered attachment designed for tractors in the 15-45 HP range, using a 540 RPM input and delivering high torque for root removal. It features a 24″ flywheel with 34 tungsten carbide teeth and a maximum cutting depth of 6 inches. A practical 3-point hitch makes installation straightforward, and a compact storage box sits above the grinder for fast tool access. This setup is suitable for forestry work, gardens, and plantations, providing efficient root disruption with minimal downtime.
MechMaxx TSG61 PTO Hydraulic Grinder
This hydraulic-driven stump grinder is built for larger compact tractors in the 35-60 HP range. It uses two hydraulic cylinders to position a 24″ cutting wheel equipped with 16 carbide teeth. The cutting depth reaches 18 inches above ground and 12 inches below, enabling aggressive stump removal and quick ground-level grading. Operators can control milling head movement from the tractor cab, improving efficiency and safety on uneven terrain.
SuperHandy Stump Grinder Teeth Set
This replacement teeth kit is specifically engineered for the SuperHandy Grinder Model GUO110. The set uses premium carbide construction designed to withstand tough stump grinding conditions and maintain efficient grinding performance. Compatibility and precise fit help keep downtime to a minimum, especially on commercial jobs where frequent teeth replacements occur.
tpengine 10-Pack Stump Grinder Teeth (2-7/8″ x 3/4″)
These carbide-tipped teeth are designed to fit a range of common stump grinder models, including 1P24/Ashland/Bradco-style heads. The packaging notes compatibility with specific lines and advises users to confirm the machine model before purchase. With carbide tips, they offer durability for repeated grinding cycles and tough root material, reducing the need for frequent replacements under heavy use.
tpengine 12-Pack 1/2″ Stump Grinder Teeth
This 12-pack includes a mix of right, left, and straight teeth designed for compatibility with the 500 Series stump grinders. Constructed from tungsten carbide and alloy materials, these teeth aim to deliver long service life and reliable cutting performance in demanding sites where compact equipment is used. The set supports quick swaps to minimize downtime on multi-day projects.
tpengine 4 Pack Straight Side 1/2″ Teeth
The 4-pack provides direct replacement straight-side teeth for 500 Series grinders. These parts are positioned as direct replacements to simplify maintenance and reduce downtime. The packaging emphasizes compatibility and straightforward installation for quick turnaround on job sites.
Buying Guide
- Machine compatibility: Confirm HP range, PTO/hydraulic drive, and mounting interface before selecting a grinder. Mini excavators vary in their hydraulic capabilities, so ensure the attachment’s power requirements align with the carrier.
- Wheel size and cutting depth: A larger wheel enables deeper cutting but adds weight and power demand. For compact machines, prioritize models with manageable cutting depth and a cutting wheel size that fits the machine’s clearance and hydraulics.
- Teeth design and material: Carbide teeth offer longer life in tough wood and root material, but cost more upfront. Tungsten carbide tips provide durability on mixed soils. Consider expected job types (soft roots, hard timber, rocky soil) when choosing replacement teeth.
- Maintenance and accessibility: Look for designs with easy tooth replacement and storage space for tools or manuals. A black tool box or similar feature can reduce downtime on-site.
- Attachment versatility: Some grinders are PTO-powered; others are hydraulic. For mini excavators, hydraulic options can deliver precise head control from the cab, enabling safer, more efficient milling on uneven terrain.
- Interchangeability and spare parts: If you operate multiple machines, consider teeth sets that fit common 500-series or 1P/Bradco-type heads to simplify inventory management.
- Cost of ownership: Compare not only the upfront price of the grinder or teeth set but also the expected tooth life, replacement frequency, and potential downtime during long projects.
