SERVICING THE MOWER BLADES
1. Blades should be sharp and free of nicks and dents.
If not, sharpen blades as described in following
steps.
2. To remove blade for sharpening, use a 1” wrench on
the flats of the spindle shaft while removing the blade
mounting bolt with a 15/16” wrench (Figure 18).
3. Use a file to sharpen blade to fine edge. Remove all
nicks and dents in blade edge. If blade is severely
damaged, it should be replaced.

blade’s hole on a nail lubricated with a drop of oil. A
balanced blade will remain level.

flat washer and torque bolts to 70 ft.lbs. (94 N.m.).
