13. 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 (Figure 91).
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.

surface to the back tip of the blade (Postion B). The
measurement should read 8.3 cm (3 1/4 inches) (Figure

16. Fine tune the screw adjuster by turning it to get 8.3 mm
(3–1/4 inches) height (Figure 89).
