Servicing the Mower Blades
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
to prevent blade rotation while loosening the
capscrew (see Figure 18).
3. Remove the capscrew (A, Figure 19), spring washer
(B), hex washer (C), 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 20. Center the
blade’s hole on a nail lubricated with a drop of oil. A
balanced blade will remain level.
6. Reinstall the blade with the tabs pointing up toward
the mower deck as shown in Figure 19. Reinstall the
hex washer (C), spring washer (B) and capscrew (A).
Use a wooden block (D) to prevent blade rotation
while tightening the capscrew (A) to 61-75 Nm (45-55
ft-lbs).
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
