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 4 deck links.
