Is This Right For You?
✅ Buy if…
- You remove tree stumps on residential or commercial properties where a dedicated stump grinder trailer isn't cost-effective
- Landscaping, tree service, or property clearing contracts where stump removal is part of the job
- You already run a skid steer and want to add stump grinding without a second piece of dedicated equipment
⛔ Skip if…
- Large hardwood stumps over 18 inches are your primary target — a heavy-duty grinder works more efficiently
- Stumps are tight against structures regularly — a side-shift model gives you access a standard unit can't
🔍 Also consider…
- Heavy-duty stump grinder for large-diameter hardwood stumps
- Side-shift stump grinder for tight obstacle-constrained work sites
🔧 Machine Compatibility
Compatible with all skid steer brands and compact track loaders via universal SSQA quick attach. Mid-frame machines (S450–S650 class) are the most common fit.

Care & Maintenance
- Check carbide tooth torque before every use — loose teeth eject at high RPM and can cause catastrophic cutterhead damage or injury
- Replace carbide teeth in matching pairs (left-right balance) to maintain cutterhead balance and reduce destructive vibration
- Grease cutterhead drive spindle bearings after every 4 hours of operation — grinding generates significant heat and vibration that accelerates lubricant breakdown
- Clean wood chips and soil from the motor ventilation shroud and belt drive area after every use — blocked ventilation causes motor overheating
- Inspect hydraulic motor fittings for loosening after hard-material sessions — the constant vibration of grinding loosens threaded fittings progressively
How to Connect
- Attach stump grinder using Bob-Tach
- Connect high-flow hydraulic couplers
- Run wheel at idle to verify direction (wheel should spin into stump, not away)
- Clear 10m radius of bystanders before grinding
⚠ Safety NoteHigh-flow required (20-40 GPM). Always wear face shield and hearing protection.
🪵 Before You Buy a Stump Grinder
Virtually all skid steer stump grinders require high-flow hydraulics — and carbide tooth condition is a major operating cost factor.
