Removing the Drive Belt

(Self-Propelled Units Only)
WARNING: Before you remove the belt,
disconnect the wire from the spark plug.
1. Remove the screw that secures the belt cover (A, Figure
22). Remove the belt cover.
2. To remove the drive belt, tip the mower up. See "Engine
Tipping" in the Maintenance section.
3. Loosen the belt tension bolt (A, Figure 23).
4. Remove the front of the drive belt (B) from the trans-
mission pulley (C).
5. To remove the rear of the drive belt (A, Figure 24), slip
the drive belt over the end of the blade (B).
Note: Make sure you replace the drive belt only with a
replacement belt from the factory.
6. To assemble the drive belt, reverse the above steps.
7. Set the belt tension.
a. Tighten the adjuster nut (A, Figure 25) until the nut
touches the spacer (B). Try to turn the spacer. When the
adjuster nut touches the spacer, the spacer will not turn.
b. Then, loosen the adjuster nut only enough to allow
the spacer to turn. The tension on the drive belt is now
correct.
8. Install the belt cover.
9. Before you begin to mow, make sure the drive system
will correctly disengage and that the mower will stop. If
the drive system will not disengage, take the mower to
an authorized service center before you operate the
mower.
