Cutting Blades

WARNING!
Shut the engine off and remove
ignition key before removing the cutting blade(s) for
sharpening or replacement. Protect your hands by
using heavy gloves when grasping the blade
WARNING!
Periodically inspect the blade and/or
spindle for cracks or damage, especially after you've
struck a foreign object. Do not operate the machine
until damaged components are replaced.
To remove the blades, proceed as follows.
1. Remove the deck from beneath the tractor, (refer to
Cutting Deck Removal earlier in this section) then gently
flip the deck over to expose its underside.
2. Place a block of wood between the center deck housing
baffle and the cutting blade to act as a stabilizer.
See Figure 7-5.
3. Remove the flange lock nut that secures the blade to the
spindle assembly. See Figure 7-5.
Figure 7-5
4. To properly sharpen the cutting blades, remove equal
amounts of metal from both ends of the blades along the
cutting edges, parallel to the trailing edge, at a 25° to 30°
angle. Always grind each cutting blade edge equally to
maintain proper blade balance. See Figure 7-6.
CAUTION:
If the cutting edge of the blade has
previously been sharpened, or if any metal
separation is present, replace the blades with new
ones.
WARNING!
A poorly balanced blade will cause
excessive vibration, may damage to the tractor and/
or result in personal injury.
