11. 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 Figure 87.

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 88).
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.

14. Tighten the two bolts at the bottom of the height of
cut plate (Figure 87). Torque to 27-33 ft-lb (37-45
N-m).
Note: In most conditions, the back blade tip should
be adjusted 1/4 inch (6.4 mm) higher than the front.
15. On both sides of the deck, measure from the level
surface to the back tip of the blade (Position B). The
measurement should read 3 1/4 inches (8.3 cm)
(Figure 85).
16. Fine-tune the adjustment nut on the front deck lift
assembly by turning it (Figure 86).
To increase the height, turn the adjustment nut
clockwise; to decrease, turn counterclockwise.
17. Measure until all four sides are the correct height.
Tighten all the jam nuts on the deck lift arm
assemblies.
18. Lower discharge chute.
