Correcting Cutting Unit
Mismatch

If there is mismatch between the blades, the grass will
appear streaked when it is cut. This problem can be
corrected by making sure the blades are straight and all
blades are cutting on the same plane.

1. Using a 3 foot long carpenters level, find a level surface

on the shop floor.

2. Raise height-of-cut to the highest position: refer to

Adjusting Height-of-Cut.

3. Lower cutting unit onto flat surface. Remove covers

from top of cutting unit.

4. Unhook spring from idler arm bracket to release belt

tension.

5. Rotate blades until the ends face forward and backward.

Measure from floor to front tip of cutting edge and
remember this dimension. Then rotate same blade so
opposite end is forward and measure again. The
difference between dimensions must not exceed 1/8 of
an inch. If dimension exceeds 1/8 of an inch, replace the
blade because it is bent. Make sure to measure all
blades.

6. Compare measurements of outer blades with the center

blade. Center blade must not be more than 3/8 of an
inch lower than the outer blades. If center blade is more
than 3/8 of an inch lower than the outer blades. proceed
to step 7 and add shims between spindle housing and
bottom of cutting unit.

7. Remove capscrews, flatwashers, lockwashers and nuts

from outer spindle in the area where shims must be
added. To raise or lower the blade, add a shim, Part No.
3256-24, between spindle housing and bottom of
cutting unit. Continue to check alignment of blades and
add shims until tips of blades are within the required
dimension.

Important

 

Do not use more than three shims at any

one hole location. Use decreasing numbers of shims in
adjacent holes if more than one shim is added to any
one hole location.

8. Hook spring onto idler arm bracket. Reinstall belt

covers.
