Drive Belts:
The drive system of the stump machine is composed of a 3V banded V­belt. The stump
machine’s V­belt tension should be checked daily.
Before beginning to check or adjust belt:
shutdown
the machine, be
sure that all moving parts
have come to a complete stop. Extreme caution
must be used to avoid death or serious injury.
Stay clear of belts, pulley, clutch and cutting blade
when they are moving.
NOTICE
To extend belt life, proper tension must be
maintained. A loose belt will cause
excessive cutting blade slippage and belt
failure. A belt that is too tight can cause
bearing, shaft and belt failure.
To adjust belt tension, loosen the 2 bolts behind clutch.
Also loosen the 4 engine mounting bolts. Turn square
head adjusting bolt on frame clockwise to tighten belt,
counter clockwise to loosen belt.
(Make sure to
tighten all 6 bolts after proper belt adjustment is
achieved).
To check belt tension, you should be able to depress the
belt down about 1/4 ­ 3/8" (6­10mm) from the original
position.
