If the front-deck links do not have enough
adjustment to achieve accurate cut height, the
single point adjustment can be utilized to gain
more adjustment.
12.
To adjust the single-point system, loosen the
two bolts at the bottom of the height-of-cut plate.
Refer to

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 4 deck links.

On both sides of the deck, measure from the
level surface to the back tip of the blade (Postion
B). The measurement should read 8.3 cm (3-1/4
inches); refer to

Fine-tune the adjuster screw by turning it to get
8.3 mm (3-1/4 inches) height (
).
To increase the height, turn the adjustment nut
clockwise; to decrease the height, turn the nut
counterclockwise.
