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 loos-
ening the hardware.
3. Remove the nut (C, Figure 16), blade washers (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 blade washers (B, Figure 16), concave
side up, and nut (C). Use a wooden block (A) to pre-
vent blade rotation while tightening the hardware.

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.
