SERVICING THE MOWER BLADES
Service Interval: Every 10 Hours or As Required
1. Remove mower deck (see “Mower Deck Removal”).
2. See Figure 14. To remove blade for sharpening, use
a block of wood to prevent blade rotation while
loosening the capscrew.
3. Remove the capscrew (D, Figure 16), spring washer
(C), hex washer (B), 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 15. Center the
blade’s hole on a nail lubricated with a drop of oil. A
balanced blade will remain level.
6. Reinstall the blade (Figure 16) with the tabs pointing
up toward the mower deck as shown.
7. Reinstall the hex washer (B, Figure 16), spring
washer (C) and capscrew (D). Use a wooden block

WARNING
For your personal safety, do not handle the sharp
mower blades with bare hands. Careless or
improper handling of blades may result in serious
injury.
