spindle for cracks or damage, especially after you've
struck a foreign object. Do not operate the machine
until damaged components are replaced.
The cutting blades can be sharpened or replaced. To do so, they
must be removed first.
To remove the blades, proceed as follows:
1. Disconnect the mowing attachment from the FLEX™ Base
Unit.
2. Pivot the mowing attachment backwards onto its
mounting assembly, as shown in Figure 6-1.
3. Place a block of wood between the center deck housing
baffle and the cutting blade to prevent the blade from
turning when loosening the blade's hex flange nut.
See the left-hand side of Figure 6-2.
4. Remove the hex flange nut that secures the blade to the
spindle assembly. See Figure 6-2.
Note: The hex flange nut is secured using a standard thread
pattern. Turn counter-clockwise to loosen.

5. Remove the blades from the mowing deck.
6. Replace or sharpen the blades. 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 6-3.

7. Test the blades for balance by balancing the blade on a
round shaft screwdriver to check. If out of balance, when
sharpening, remove metal from the heavy side until it
balances evenly. During sharpening the blade, follow the
original angle of grind. Grind each cutting edge equally to
keep the blade balanced.
