SERVICING THE MOWER BLADES
1. Blades should be sharp and free of nicks and
dents. If not, sharpen blades as described in the
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
25).
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 26. Center
the blade’s hole on a nail lubricated with a drop of
oil. A balanced blade will remain level.

toward deck as shown in Figure 27. Secure with a
bolt and flat washer and torque bolts to 70 ft.lbs.
