the distance measured
9. Compare the measurements at various positions. All
dimensions must be equal within 6 mm (1/4 inch)
from any 2 adjacent blades. The difference between
the dimensions of all 3 blades must not exceed 10 mm
(3/8 inch). If the difference exceeds specifications,
proceed to step 10.
10. Remove the bolts, flat washers, and locknuts from
the outer spindle in the area where the shims must be
added. To raise or lower the blade, add a shim, between
the spindle housing and bottom of the mower deck.
Continue checking the alignment of the blades and
adding shims until the tips of the blades are within the
required dimension.
