How to Grind Stumps
Align the cutter wheel with the left side of the stump (viewed from the machine control area) and position the machine so
that it will cut about 4-6 inches off the top of the stump and 8-12 inches from the left side of the stump. See FIGURE A.
The rate of cut will depend on the type of tree, condition of the wood, and the condition of the cutters. Too light a feed
will produce sawdust. The ideal feeding rate produces heavy wood chips, some of which may be about 1/16” thick by
approximately 6-8 inches long, as well as chunks of wood. After completing the first cut through the stump, move the
machine to the right (again as viewed from the control area) so the wheel can cut another 8-12 inches. Proceed with
anther cut. Additional passes, when the tree stump is very large, are made in the same manner as described above.
Repeat the procedure until the stump is cut to ground level.
Before cutting below the ground level, make certain that all rock or stone is removed from the immediate area of the
cutting wheel. When you are cutting below the ground level, the feed rate should be reduced and the operator should be
alert to the possibility of cutting hidden rock. Extra care used in this part of the operation can avoid costly damage to the
cutting wheel and teeth.
The wheel is designed so that it can “saw” or cut its way into solid wood by dropping straight down on it. This operation
works well for cutting off large roots.
