lift assembly by turning it
Note:
To increase the height, turn the
adjustment nut clockwise; to decrease, turn
counterclockwise.

adjustment to achieve accurate cut height,
use the single-point adjustment to gain more

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 regains some up and down adjustment on
each of the 4 deck links.
