12. 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 129 ).
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 regains some up and down adjustment on
each of the 4 deck links.

13. T ighten the 2 bolts at the bottom of the
height-of-cut plate ( Figure 127 ).
Note: In most conditions, the back blade tip
should be adjusted 6.4 mm (1/4 inch) higher
than the front.
14. T orque the 2 bolts to 37 to 45 N∙m (27 to 33 ft-lb).
15. On both sides of the deck, measure from the
level surface to the back tip of the blade (postion
B) as shown in Figure 124 .
Note: The measurement should read 8.3 cm
(3-1/4 inches)
16. Fine tune the screw adjuster by turning it to get
8.3 mm (3-1/4 inches) height ( Figure 126 ).
T o increase the height, turn the adjustment nut
clockwise; to decrease, turn counterclockwise.
17. Measure until all 4 sides are the correct height.
18. T ighten all of the nuts on the deck-lift-arm
assemblies.
19. For side-discharge machines, lower the
discharge chute.
