A
Blades may be sharp. When you handle blades,
wear heavy gloves or wrap end of blade with a
rag.

Replace the blades if they appear similar to blade (C).
C
Replacing
1. Dismount the mower deck from the machine.
(See "DISMOUNTING THE MOWER DECK" in
"MOWER MOUNTING" section.)
Then turn it over to expose the blades.
2.
[RCK60P]
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.
A
Use the proper metric 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 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. Pass the spline boss through the blade and 2 cup
washers, and tighten the bolt.
A
Make sure that the cup washer is not flattened out or
worn; this cause blade to slip excessively.
Replace the 2 cup washers if either is damaged.
6. Before checking or replacing the blade, wipe grass
and mud off the top and inside of the mower.
Especially clean up the inside of the belt cover,
because otherwise the belt life will be reduced.
