Inspect the blades for nicks or dull edges. Use a file
to sharpen blade to a fine edge. If the blade is dam-
aged, it must be replaced.
Balance the blade as shown in Figure 26. Center the
blade's hole on a nail lubricated with a drop of oil. A
balanced blade will remain level. If the blade is not
balanced, continue to sharpen the heavy side until it
balances.
Reinstall the blade with the lift wings (C, Figure 25)
pointing up toward the mower deck as shown.
Reinstall the spring washer (B) and capscrew (A).
Use a wooden block (B) to prevent blade rotation
while tightening the capscrew (A) to 45-55 ft-lbs (61-
