3.
Insert the belt adjustment tool through
the hole in the side of the adjustment
block, spacing the ends of the tool equally
on both sides (Figure 5-14). Rotate the
tool so the slotted end faces down.
4.
Place the Wheels/Tines/PTO Drive
Lever in FORWARD position. The arms
of the clutch control yoke will be resting
on the belt adjustment tool and the clutch
roller should be engaged slightly beneath
the adjustment block (Figure 5-15).
5.
Use one hand to hold the drive lever in
FORWARD while using a 9/16" wrench to
loosen (don’t remove) the bolt at the back
of the belt adjustment block (Figure 5-16).
The adjustment block should be free to
move either up or down.
6.
Push the drive lever down if the belt
needs tightening. Pull the lever up if the
belt needs to be loosened. Hold the drive
lever in place and tighten the bolt in the
adjustment block firmly.
7.
Let go of the drive lever and remove
the belt adjustment tool from the hole in
the adjustment block.
8.
Check the tension on the belt by
following the previous instructions “How
to Measure Belt Tension.”
NOTE: If the adjustment block is all the
way down and the measurement between
the clutch roller and the bracket is less
than 1/4", then a new drive belt is needed.
Replacing the Drive Belt
Removing the Belt
1.
Move Wheels/Tines/PTO Drive Lever to
NEUTRAL position.
2.
While kneeling on the right side of the
tiller, create slack in the belt by reaching
over to the left side of the pulleys and
pushing in on the center of the belt with
your finger.
3.
Use your right hand to move the belt
down and away from the lower pulley, in
the direction of the engine (Figure 5-17).
4.
Push the belt upward to create slack in
the belt (Figure 5-18).

the upper pulley and the rubber reverse
disc, moving it in front of the reverse disc
(refer to Figure 5-19).
