Is This Right For You?
Buy if
- You grind hardwood stumps over 18 inches diameter — large oaks, maples, or elms that standard grinders struggle with
- Production tree service or land clearing where stump count and diameter are high
- Your large-frame skid steer has the hydraulic flow and lift capacity to run a heavy grinder effectively
Skip if
- Most of your stumps are under 12 inches — a standard grinder completes those faster with less wear
- Your machine is compact or mid-frame — a heavy grinder may exceed carrier capacity
Also consider
- Standard stump grinder for typical residential and light commercial stump removal
- Side-shift stump grinder if you work near obstacles frequently
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
