If the deck is too low, tighten the single point
adjustment bolt by rotating it clockwise. If
the deck is too high, loosen the single point
adjustment bolt by rotating it counterclockwise.
Note:
Loosen or tighten the single point
adjustment bolt enough to move the height of cut
plate mounting bolts at least 1/3 the length of
the available travel in their slots. This will regain
some up and down adjustment on each of the
four deck links.
