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 16).
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.
4. Balance the blade as shown in Figure 17. Center the
blade’s hole on a nail lubricated with a drop of oil. A
balanced blade will remain level.

deck as shown in Figure 18. Secure with a bolt and
flat washer and torque bolts to 70-90 ft.lbs. (94-120
N.m.).

For your personal safety, blade mounting bolts
must each be installed with a flat washer then
securely tightened. Torque blade mounting bolts
to 70-90 ft.lbs. (94-120 N.m.)
