CLUTCH ADJUSTMENT
Your Stump Grinder is equipped with a brake clutch that controls the motion of the cutter head. When engaged
the clutch allows the cutter head to spin, when disengaged the clutch will stop the cutter head in under 2
seconds. It is critical that the clutch control cable be adjusted properly.
To adjust the clutch control cable:
1. Remove belt guard and disconnect clutch control cable from spring attached to clutch engagement lever
(item C, fig. 11).
2. With engagement lever fully forward measure 1 ½ “ backwards from the left hand edge of the lever and
make a mark on the clutch housing.
3. Re-connect the clutch control cable and adjust the jam nuts (item A, fig. 11) forwards or backwards as
necessary so that the lever does not pull backwards.
4. Compress the operator presence handle and check that left hand edge on the engagement lever moves
to the mark on the clutch housing.
5. Adjust cable accordingly if lever moves to the left or right of the mark.
6. If more adjustment is needed, move the cable end support (item B, fig. 11) as necessary.
Clutch cable tension should be checked periodically along with belt tension.

CLUTCH SERVICING
The clutch is shipped from the factory assembled and adjusted. No internal adjustment is available to the end
user. For service, return the clutch to the factory.
