Figure 9: Belt Pattern and Spring Adjustment (Model C60K)
For Model E60B: - See Figure 10.
With the clutch engaged, adjust the nuts on the spring loaded idler adjuster bolt until the length of
the spring is between 2-1/4” and 2-3/8”. This model comes with a belt brake when the clutch is
disengaged. This is a safety feature to stop the blades from turning after the clutch is disengaged.
To ensure that the brake works properly the spring length must be set correctly. With the clutch
disengaged make sure the spring length is no more then 2-3/4”.
The brake stud must be adjusted. If the brake stud is not adjusted correctly, the
blades will still spin even though the clutch may be in the disengaged position.
Always shut mower engine off before servicing.
To the adjust brake place clutch in the engaged position. Loosen the bolt on the top of the brake
stud. Slide the brake stud in the slot until there is about 1/2” of clearance between the belt and
the brake stud. Tighten the bolt at the top of the brake stud.
If brake stud is not set in correct position underbraking or overbraking may occur.
If overbraking occurs premature belt failure could occur and possible fire due to
overheating.
