Cutting Blades

WARNING:
Shut tractor engine off, remove ignition key, disconnect the spark plug wire(s) and ground
against the engine before proceeding with job. Protect your hands by using heavy gloves or a rag to grasp
the cutting blade
• Periodically inspect the blade adapter and/or spindle for cracks or damage, especially if you strike a foreign
object. Replace immediately if damaged
1. Remove the deck from beneath the tractor, 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 14.
3. Using a 15/16" wrench, remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 14.
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. See Figure 14.
• If the cutting edge of the blade has already been
sharpened to within 5/8" of the wind wing radius, or if
any metal separation is present, replace the blades
with new ones. See Figure 14.
Each cutting blade edge has to be ground
IMPORTANT:
equally to maintain proper blade balance. A poorly
balanced blade will cause excessive vibration, may
damage the tractor and/or result in personal injury.

screwdriver. Grind metal from the heavy side until it
balances evenly.
6. When replacing the blade, be sure to install the blade
with the side of the blade marked ''Bottom'' (or with a
part number stamped in it) facing the ground when
the mower is in the operating position.
7. Use a torque wrench to tighten the blade spindle hex
flange nut to between 70 and 90 foot-pounds.
