MAINTENANCE
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.
