6.2 Grinding Procedure

1. Start Tractor and Engage PTO: Start the tractor and engage the PTO at a low RPM. Gradually increase to the recommended 540 RPM.
2. Position Grinder: Slowly lower the stump grinder until the cutting wheel is just above the stump.
3. Begin Grinding: Engage the cutting wheel with the edge of the stump. Move the tractor slowly and steadily, allowing the grinder to cut through the stump. The tractor's movement rate should be independent of the PTO speed.
