8. Using the lift and swing levers to direct the
stump grinder, make the first pass across the
front edge of the stump, moving the cutting
wheel from right to left in 3 - 6 in. (76 - 152
mm) passes. The size of the pass will depend
on the power and size of the tractor. Larger
passes can be handled by a larger tractor.
Return the grinder to the far right after each
pass.
9. Continue to take passes across the front edge
of the stump, taking 3 - 6 in. (76 - 152 mm) on
each pass.
10. When ground level is reached, continue to
grind 3 - 6 in. (76 - 152 mm) below the surface
to the bottom of the stump where the roots
branch out.
11. Lift the stump grinder and swing it to the far
right. Back the tractor up slightly to position the
stump grinder beside the new front edge of the
stump.
12. Make multiple passes over the front edge of
the stump, taking 3 - 6 in. (76 - 152 mm) on
each pass.
13. Reposition the tractor and stump grinder
as needed until the entire stump has been
removed to below ground level.
14. Follow the roots, taking as much of the larger
surface roots as possible. If these are not
removed they can, over time, protrude from the
ground in areas where there is a heavy freeze/
thaw cycle.
15. Throttle down the tractor to an idle.
16. Disengage tractor PTO.
17. Shut off engine and remove key.
