NOTE: Mower blades must be timed perpendicular to
each other.
1. Remove mower deck (see “Mower Deck Removal”).
2. To remove blade for sharpening, use a block of wood
(Figure 17) to prevent blade rotation while loosening
the capscrew.
3. Remove the bolt (A, Figure 18), spring 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 19. 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 18) with the tabs pointing
up toward the mower deck as shown. Reinstall the
spring washer (B) and bolt (A). Use a wooden block
(C) to prevent blade rotation while tightening the bolt
to 45-55 ft-lbs (61-75 Nm).
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.
WARNING
For your personal safety, blade mounting
capscrews must each be installed with a
hex/spline washer and spring washer, then
securely tightened. Torque blade mounting
