• 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.
