4. Pull the cable to the remove slack, but do not put
tension on the spring. Tighten the cable clamp screw
to lock the adjustment in place.
Warning
Do not overtighten the blade brake cable.
Overtightening the blade brake cable could cause
the blade brake to come off of the brake drum. If
the brake does not contact the drum, the blade
will not stop rotating when you release the control
bar. A rotating blade could cause serious personal
injury.
• Each time you adjust the brake cable, ensure
that the brake stops the blade in 3 seconds or
less.
• If the blade does not stop rotating in 3 seconds
or less, bring the lawn mower to an Authorized
Service Dealer for inspection and repair.

4. Separate the wheel halves from the tire by removing
4 bolts and 4 locknuts (Fig. 35).
Note: If you remove the bearings from the bearing/hub
assembly, remove them by pressing on the bearing spacer
(Fig. 35).
Assembling the Wheels
1. Position the tire onto one wheel half, aligning the lugs
on each (Fig. 35).
2. Place the bearing/hub assembly into the center hole of
the wheel half. Ensure that the legs of the hub are
positioned over the flange of the hole (Fig. 35).
3. Place the other wheel half onto the bearing/hub
assembly, aligning the wheel and the tire lugs and the
mounting holes (Fig. 35).
4. Using 2 fully threaded bolts (1/4–20 x 1.50 inch) and
non-locking nuts, loosely secure the wheel halves
together. Mount the bolts in the opposing holes
(Fig. 35).
5. Check the alignment of all parts and tighten the bolts,
alternating from side to side for a uniform fit, until the
wheel halves are drawn together (Fig. 35).
6. Install the 2 bolts and 2 locknuts previously removed
in the remaining holes in the wheel halves and tighten.
Remove the 2 long bolts and replace them with 2 bolts
and 2 locknuts (Fig. 35).
7. Install the wheel to the pivot arm with the bolts, a
spacer, and a locknut. Ensure that the spacer is
positioned between the wheel hub and the pivot arm
(Fig. 35).
