Note:
Sharpen only the top of the cutting
edge and maintain the original cutting angle
to ensure sharpness (
Figure 116 ). The blade
remains balanced if the same amount of metal
is removed from both cutting edges.

1. Sharpen at the original angle.
Note:
Remove the blades and sharpen them
on a grinder. After sharpening the cutting edges,
install the blade with the anti-scalp cup and
blade bolt; refer to
Removing and Installing the
Mower Blade(s) (page 78) .
Correcting a Mower-Deck
Mismatch
If there is mismatch between the blades, on a single
mower deck, the grass will appear streaked when it is
cut. This problem can be corrected by ensuring that
the blades are straight and all of the blades are cutting
on the same plane.
1. Park the machine on a level surface of the shop
floor.
2. Raise the height of cut to the highest position;
refer to
Adjusting the Height of Cut (page 29) .
3. Lower the mower deck onto the flat surface and
remove the covers from the top of the mower
deck.
4. Loosen the flange nut securing the idler pulley
to release the belt tension.
5. Rotate the blades until the ends face forward
and rearward and measure from the floor to the
front tip of the cutting edge.
Note:
Remember this dimension. Then rotate
the same blade so that the opposite end is
forward, and measure again. The difference
between the dimensions must not exceed 3
mm (1/8 inch). If the dimension exceeds 3 mm
(1/8 inch), replace the blade because it is bent.
Measure all the blades.
6. Compare the measurements of the outer blades
with the center blade.
Note:
The center blade must not be more than
10 mm (3/8 inch) lower than the outer blades. If
the center blade is more than 10 mm (3/8 inch)
lower than the outer blades, proceed to step
7
and add shims between the spindle housing and
the bottom of the mower deck.
7. Remove the bolts, flat washers, lock washers,
and nuts from the outer spindle in the area
where the shims must be added.
Note:
To raise or lower the blade, add a shim
(Part No. 3256-24) between the spindle housing
and the bottom of the mower deck. Continue
to check the alignment of the blades and add
shims until the tips of the blades are within the
required dimension.
Important:
Do not use more than 3 shims at
any 1 hole location. Use decreasing numbers
of shims in adjacent holes if more than 1
shim is added to any 1 hole location.
8. Adjust the idler pulley and install the belt covers.
