WARNING: Periodically inspect the blade adapter and/or spindle for cracks or damage, especially if you strike a foreign object. Replace immediately if damaged.
The blades may be removed as follows.
•Remove the deck from beneath the tractor, (refer to DECK REMOVAL) then gently flip the deck over to expose its underside.
•Place a block of wood between the center deck housing baffle and the cutting blade to act as a stabilizer. See Figure 20.
•Use a 15/16" wrench to remove the hex flange nut that secures the blade to the spindle assembly. See Figure 20.
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 21.
IMPORTANT: 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 21.
It is important that each cutting blade edge be ground equally to maintain proper blade balance.
A poorly balanced blade will cause excessive vibration and may cause damage to the tractor and result in personal injury.
The blade can be tested by balancing it on a round shaft screwdriver. Grind metal from the heavy side until it balances evenly.
