• Replacing
1.
Remove the mower deck from the machine
and
turn it
over to expose the
blades.
2.
Wedge a block of wood between the blade and mower
housing or use a box wrench over the
pulley nut to
prevent the
spindle from rotating while removing the
blade bolts; loosen the blade bolt
as
illustrated.
IMPORTANT:
• Use the proper metric size box or socket wrench to
tighten or
loosen the blade mounting bolt.

NOTE:
• Use the proper size box or socket wrench to tighten or
loosen the blade mounting bolt.
3.
To
sharpen the blades yourself, clamp the blade
securely
in
a vise.
Use a
large mill file
and
file along the original bevel
until it becomes sharp.
4.
To check the blade for balance, place a small
rod
through the center hole. If the blade
is
not balanced,
file the heavy side of the blade until balance
is
achieved.
5.
To
attach blades, be sure
to
install the cup washer
between the
blade
and
the bolt head.
6.
Before checking or replacing the blade, wipe grass
and
mud
off the top and the inside of the mower.
Especially clean
up
the inside of the belt cover,
because otherwise the
belt life will
be
reduced.
