blade edge is dull or nicked, have it sharpened and balanced,
or replace it.
WARNING
The blade is sharp; contacting the blade can result
in serious personal injury.
Wear gloves when servicing the blade.
1.
Refer to Preparing for Maintenance (page 12).
2.
Tip the mower onto its side with the air filter up.
3.
Use a block of wood to hold the blade steady
(Figure 18).
Figure 18
4.
Remove the blade, saving all mounting hardware
(Figure 18).
5.
Install the new blade and all mounting hardware
(Figure 19).
Figure 19
Important:
Position the curved ends of the blade
to point toward the mower housing.
6.
Use a torque wrench to tighten the blade bolt to
60 ft-lb (82 N-m).
Important:
A bolt torqued to 60 ft-lb (82 N-m) is
very tight. While holding the blade with a block
of wood, put your weight behind the ratchet or
wrench and tighten the bolt securely. This bolt is
very difficult to overtighten.
Adjusting the Self-propel Drive
Cable
Whenever you install a new self-propel cable or if the
self-propel drive is out of adjustment, adjust the self-propel
drive cable.
1.
Loosen the cable support nut (Figure 20).
2.
Pull down the cable jacket (toward the mower) until
there is no slack in the cable (Figure 20).
3.
Tighten the nut on the cable support.
