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.
14. Tighten the 2 bolts at the bottom of the height-of-cut
plate (Figure 93).
Note: In most conditions, the back blade tip should
be adjusted 6.4 mm (1/4 inch) higher than the front.
