Servicing the Mower Blades
NOTE: Mower blades must be timed perpendicular to
each other.
1. Remove mower deck (see MOWER DECK
REMOVAL).
2. To remove blade for sharpening, use a block of wood
to prevent blade rotation while loosening the
capscrew (see Figure 18).
3. Remove the capscrew (
A
, Figure 19), spring washer
(
B
), hex washer (

), and blade.
4. Use a file to sharpen blade to a fine edge. If blade is
damaged, it must be replaced.
5. Balance the blade as shown in Figure 20. Center the
blade’s hole on a nail lubricated with a drop of oil. A
balanced blade will remain level.
6. Reinstall the blade with the tabs pointing up toward
the mower deck as shown in Figure 19. Reinstall the
hex washer (

) and capscrew (
A
).
Use a wooden block (

while tightening the capscrew (

ft-lbs).
