(20 mm) thick down on a level surface and lower the
cutting unit onto the flat surface.
3. Rotate blade so ends face fore and aft. Measure from
flat surface to front tip of cutting blade and record
dimension. Rotate same blade so opposite end faces
forward and repeat measurement. Difference between
the two measurements must not exceed 1/8 in. (3 mm).
If difference exceeds 1/8 in. (3 mm), the blade is bent.
Replace it. Use same procedures to measure all blades.
4. Rotate blade so ends face fore and aft. Measure from
flat surface to front of cutting blade and record
dimension. Repeat process with all blades and compare
measurements. Maximum difference allowed between
any two adjacent blades is 1/4 in. (6 mm). Maximum
difference allowed between the highest and lowest
blade measurement is 3/8 in. (10 mm). If measurements

do not fit recommended standards, add shims between
the cutting deck and spindle housing; proceed to step 6.
If measurements meet standards, proceed to step 5.
5. Rotate blades so tips line up with one another. Tips of
adjacent blades must be within 1/8 in.(3 mm) of each
other. If tips are not within 1/8 in. (3 mm) of one
another, add shims between spindle housing and bottom
of cutter deck; proceed to step 6.
6. Remove locknuts securing spindle housing to deck in
area where shims are to be added. To lower a blade, add
a shim (Part No. 3256–24), to each mounting bolt,
between spindle housing and cutter deck. Repeat step 5.
Continue process until blade tips are within the required
dimensions.
Important
Do not exceed three shims at any one hole
location. If more than one shim is added to any one hole
location, install decreased amounts of shims in adjacent
holes.
Adjusting the Winglet
Stabilizers
If front winglet decks bounce excessively when in
transport, an adjustment to the winglet stabilizers is
required.
1. Park machine on a level surface, engage parking brake,
lower front deck completely to the ground and turn the
engine OFF.
2. Loosen capscrews securing winglet stabilizer brackets
to deck and move brackets outward (Fig. 75).
